Array data, or other data generated based on thermal image signals. In the following, the thermal image data frame is exemplified by a thermal image signal.

 The temporary storage unit 2 is a buffer memory that temporarily stores a thermal image data frame output from the imaging unit 1 as a buffer memory that temporarily stores the thermal image data frame output from the imaging unit 1. For example, the following processing is repeated, and the acquired thermal image data frame is temporarily stored for a predetermined time.

In the card slot, data such as a thermal image data frame is recorded under the control of a recording control unit (not shown) of the control unit 11.

 The image processing unit 7 is configured to perform predetermined processing on the thermal image data frame obtained by the imaging unit 1, for example, a thermal image of a predetermined time portion temporarily stored in the temporary storage unit 2 when the display timing comes. In the data frame, the frame of each predetermined time interval is selected and read; the processing of the image processing unit 7 is converted into data suitable for display, recording, etc., such as correction, interpolation, pseudo color, synthesis, compression, decompression, and the like. deal with. The image processing unit 7 can be realized by, for example, a DSP or another microprocessor or a programmable FPGA, or can be integrated with the processor corresponding to the detecting unit 8 and the control unit 11.

 The image processing unit 7 performs predetermined processing on the thermal image data frame (e.g., thermal image signal) obtained by the imaging unit 1 to obtain image data of the infrared thermal image. Specifically, for example, the image processing unit 7 performs predetermined processing such as non-uniformity correction and interpolation on the thermal image data frame obtained by the imaging unit 1, and performs pseudo color processing on the thermal image data frame after the predetermined processing to obtain an infrared thermal image. Image data; an embodiment of the pseudo color processing, for example, determining the corresponding pseudo color table range according to the range of the thermal image AD value data or the setting range of the thermal image AD value data, and the thermal image data is in the pseudo color plate range The corresponding specific color value is used as the image data of the corresponding pixel position in the infrared thermal image. The image data obtained after the pseudo color processing by the image processing unit 7 is transferred to the temporary storage unit 2 used as a buffer memory.

 Further, the image processing unit 7 includes a synthesizing unit (not shown) that obtains a reference image based on the configuration data of the reference image specified by the reference image specifying unit 11F and the positional parameter set by the position setting unit 11G, and The infrared thermal image generated by the image processing unit 7 is combined to generate image data of the composite image. Specifically, the image synthesizing unit synthesizes the reference image and the infrared thermal image according to a prescribed transparency ratio; in this case, the transparency of the reference image is 1 (eg, the reference image is a line image of the edge contour), that is, opaque and Infrared thermography synthesis.

 The image processing unit 7 is configured to perform predetermined processing on the acquired thermal image data frame based on the configuration data of the designated reference image and the position parameter set by the position setting unit 11G to generate an infrared thermal image in which the reference image is reflected.

 In addition, the synthesis may also be based on such processing, for example, performing pseudo color processing on the thermal image data frame according to the pixel position of the reference image located in the infrared thermal image to generate display image data embodying the reference image and the infrared thermal image. (similar to the effect of overlapping); for example, according to the pixel position of the reference image located in the infrared thermal image, the thermal image data of the pixel position is not subjected to pseudo color processing, and the thermal image data other than the pixel position of the reference image is pseudo-colored. Processing, and then combining the image data of the reference image to generate image data for display.

Alternatively, the reference image may be processed differently from the thermal image data of the pixel position in the thermal image data frame by the pseudo color processing of the thermal image data of the other image position of the infrared thermal image (eg, different pseudo color). Processing) to generate a body . , loo can

An image synthesis unit that combines image data with an infrared thermal image.

 The so-called reference image, which is displayed together with the infrared thermal image, helps the user to shoot a specific subject. For example, an image embodying the morphological features of the particular subject; the reference image may also be other shapes, such as a square or a circle; for example, an identification image that reflects a desired imaging position of the subject thermal image in the infrared thermal image. For example, an identification image that reflects a detection area in the infrared thermal image (the detection area may include one or more detection windows); for example, an identification image of an analysis area that embodies a desired subject thermal image, and the like. Preferably, the reference image is displayed superimposed on the infrared thermal image according to a prescribed positional parameter (position, or also including size, or also including a rotation angle).

 In addition, the reference image may also be displayed in the display portion, outside the infrared thermal image window; in addition, a thumbnail representing the relationship between the reference image and the position and size ratio of the infrared thermal image may be displayed in the infrared thermal image window. The area of the display unit outside.

 The detecting unit 8 performs correlation calculation with the subject identification information based on the thermal image data frames of the plurality of frames stored in the temporary storage unit 2 (thermographic image storage unit); wherein, it may be in the temporary storage unit 2 Part or all of the thermal image data frames are subjected to detection processing, for example, reading all the thermal image data frames in sequence for detection processing, for example, reading only the thermal image data frames of a predetermined interval for detection processing; for example, when the correlation is detected for the first time And/or when the thermal image data frame whose evaluation value is larger than the comparison value, the detection is not continued; for example, the detection is started or stopped in response to the predetermined operation of the user; or the thermal image data frame or the detection window is also read. The thermal image data is reduced before the data is detected; thereby, the processing load associated with the detection can be reduced.

 The thermal image data frame associated with the detection may be a thermal image signal (thermal image AD value data), or image data of an infrared thermal image, or array data of thermal image temperature values, or other data obtained based on a thermal image signal. For example, the detecting unit 8 can read the obtained thermal image data frame by reading the imaging unit 1 stored in the temporary storage unit 2 or by reading the image processing unit stored in the temporary storage unit 2 based on the control of the control unit 11. The data obtained by performing predetermined processing on the obtained thermal image data frame by the imaging unit 1 (for example, image data of an infrared thermal image obtained by pseudo color processing) is used to perform detection of correlation between the registered subject identification information and the registered object identification information. deal with.

 It is not limited to the thermal image data frame captured by the imaging unit 1 , and in other examples, the thermal image obtained from externally input data, for example, continuously received and decoded from other thermal imaging devices by the I/F 4 . Data Frame.

 In the first embodiment, the detecting unit 8 includes a feature registration unit, a detection window setting unit, and a detecting unit (not shown). The feature registration unit is configured to register the subject identification information related to the correlation calculation. For example, the subject identification information may be registered according to the subject identification information stored in advance in the storage medium; for example, registered for the correlation calculation based on the subject identification information associated with the selected subject information of the user. Subject identification information. Further, the subject identification information may be specified by the user, for example, subject identification information (e.g., template data, or extracted feature amount) may be obtained by specifying a subject region from the display image. The registered subject identification information is stored, for example, at a predetermined position of the temporary storage unit 2, or is distinguished from other stored subject identification information by the mark when stored.

The object identification information may be template data (such as a template image) for template matching; in addition, the object identification information may also be a feature quantity of the parameter description, so-called feature quantity (point, line, surface, etc.), For example, a value determined according to the state of the pixel included in the detection window, such as a ratio of a predetermined partial pixel in a specific detection window, an average value of pixel values, a center point of an outline of a specific subject, an area, and the like. For example, with respect to the subject 1 in Table 3, the subject identification information is the template data 301, and for the subject 2 in Table 3, the subject identification information is the feature amount 302. In a specific application, a combination of one or more types of subject identification information may be selected according to circumstances. Yuan, mouth. a Gi), a plurality of detection windows (for example, parameters for predetermining the detection window according to quality requirements) are disposed in the detection area G1, and may be a plurality of detection windows of different sizes, or may be a detection window after a further tilt, such as Figure 4, where Figure 4 (a) is the standard detection window, Figure 4 (b) is the detection window according to the reduced size, Figure 4 (c) is the detection window set by the enlarged size, Figure 4 (d) is according to A detection window that is set to be inclined at an angle. In order to be equal to the size of the detection window, the template image is used here in a state of being reduced or enlarged or also tilted, or a template image having a size equal to the window size may be prepared and stored for use. Further, the thermal image data in the detection window may be used in a state of being reduced or enlarged or also tilted to correspond to the template image. The detection window is not limited to a square shape, and may be other shapes, for example, depending on the shape of the template image.

 The detection area may be set by the user according to the shooting habit; or may be pre-stored as associated with the subject information; or may be generated based on the position where the specific subject thermal image was last detected; or the specific detection may not be set. The area, and the range of the thermal image data frame is the detection area. It is also possible to set a plurality of detection windows by a user-specified position and size. In addition, it is not necessary to set multiple detection windows, or only one detection window.

 It should be noted that for the application field of infrared detection, for example, a substation is filled with a large number of similarly shaped devices, but different names, in order to avoid misleading users and accidental shooting, it is preferable to set the detection area. The identification of the detection area is superimposed on the infrared thermal image, and the user can easily understand the approximate position and size of the specific subject thermal image captured, which facilitates the shooting reference and speeds up the detection process, but the detection area may not be displayed. .

 The detecting unit obtains a value for evaluating the correlation based on the subject identification information based on the thermal image data in the detection window set by the detection window setting unit in the read thermal image data frame. When a plurality of detection windows are set, for example, the value of the maximum correlation obtained by the detection may be used as the value of the correlation of the thermal image data frame.

 The detecting process of the detecting unit 8 may be based on a template matching detection method, and perform correlation calculation and comparison based on the thermal image data in the detection window and the template image; for example, the detecting unit calculates the infrared thermal image in the detection window and as a template The sum of the differences between the pixels of the positions at which the infrared thermal images correspond to each other, the smaller the sum of the calculated differences, the higher the correlation. For example, an embodiment in which the feature amount is extracted for matching may be configured, and the correlation is determined using a comparison between the template image and the feature amount of the thermal image data in the detection window. For example, the closer the ratio of the specific pixel of the subject image in the detection window is extracted to the specific pixel in the template image, the higher the correlation.

 The detection processing of the detection unit 8 may be a detection method based on the feature amount of the parameter description, performing a predetermined calculation to obtain the feature amount of the thermal image data in the detection window, and the reference value (subject identification information) of the feature amount. Compare to get the value of the correlation. For example, the reference value of the feature amount is a ratio of pixels of a specific pixel value, and the detecting unit calculates a ratio of pixels of a specific pixel value in the thermal image data, and compares it with a reference value of the feature amount to obtain a correlation between the two. The value of the degree.

In a preferred embodiment, the contour image is used as a matching template, and the detecting unit 8 calculates the correlation degree by, for example, the following processing. First, the detecting unit 8 extracts the thermal image data located in the detection window, and reads it according to a predetermined threshold value of the AD value. The thermal image data in the detection window is binarized; then, a connected image of pixels of the binary image having a predetermined pixel value (1 or 0) is connected; and then it is determined whether the connected image has a predetermined range of sizes; If it is judged that the size of the connected image is within a predetermined range, a comparison process is performed between the extracted connected image and the registered template, for example, the sum of the ratios of the overlapping areas between the two in the respective total areas is calculated. Thereby, the correlation between the extracted thermal image data and the template is obtained. TM , 5 , 8 501

Move window J1 to the lower right corner to detect, cut the thermal image data in the window, and detect its correlation with template image T1. Specifically, the window J1 is gradually moved from the left end to the right with a window displacement of a prescribed value (for example, one pixel), and after reaching the right end, is set to return to the left end and move the window displacement downward, and then gradually move to the right again. . In order to detect the subject with high precision, the range of the detected window size, window displacement, and tilt angle of the window is defined in advance, for example, the window size varies from 150 X 50 pixels to 120 X 40 pixels, and the range of window displacement varies. From 10 pixels to 1 pixel, the tilt angle of the window varies from 0° to 10° based on the center point. The detecting section 8 successively changes the window size by 5 pixels at a time, and changes the window displacement by 1 pixel at a time, and changes the window tilt angle by 2° each time. The detecting unit 8 performs correlation calculation of the template image T1 and the thermal image data frame 501; after completing the detection of all the detection windows, the value of the correlation obtained by selecting the detection window with the highest correlation is selected as the thermal image data frame 501. The value of the corresponding relevance.

 Note that various methods of calculating the degree of correlation of the thermal image data frame based on the subject identification information, the above-exemplified processing is only an example of a usable method.

 The display control unit 9 displays the image data for display stored in the temporary storage unit 2 on the display unit 10. For example, in the shooting standby mode, the infrared thermal image generated by the thermal image data obtained by the shooting is continuously displayed; in the playback mode, the infrared thermal image read and expanded from the memory card 6 is displayed, and various setting information can be displayed. . Specifically, the display control unit 9 includes a VRAM, a VRAM control unit, a signal generating unit (not shown), and the like, and the signal generating unit periodically reads out image data from the VRAM under the control of the control unit 11 (from temporary storage). The portion 2 reads and stores the image data to the VRAM, and generates a video signal output, which is displayed on the display unit 10. In the thermal imaging device 100, the display portion 10 is, for example, a liquid crystal display device. The display unit 10 may be other display devices connected to the thermal image device 100, and the thermal image device 100 itself may have no display portion in its electrical configuration. In this case, the display control portion 9 may also be an example of an image output member. .

 Further, in the first embodiment, the display unit 10 is configured to display the notification information based on the control of the notification unit 11C; for example, to warn with characters and images, such as displaying the information of the maximum correlation, and displaying the thermal image data of the maximum correlation. The infrared thermal image obtained by the frame is also notified by means of the transparency of the text, the image, the color, the size, the line shape, the thickness, the flicker, the brightness, and the change of the frame.

 Among them, the notification method can last for a specified time. Further, it is also possible to control a vibrating member, an indicator lamp (not shown) in the thermal imaging device 100, an analyzing member (not shown), and a diagnostic member (not shown) when the thermal image data frame of the maximum correlation is detected. , the light can also be changed by the indicator light, the vibration is generated by the vibration device, analyzed by the analysis component and the analysis result is displayed, the diagnosis component is diagnosed and the diagnosis result is displayed; or one or more of the above methods are notified, as long as The way the user can perceive it.

 The control unit 11 controls the overall operation of the thermal imaging device 100, and stores a program for control and various data used for control of each part in a storage medium such as the flash memory 3. The control unit 11 is realized by, for example, a CPU, an MPU, a SOC, a programmable FPGA, or the like. In the present embodiment, the control unit 11, the display unit 10, and the like are also configured as a subject information selecting unit for selecting subject information.

Further, the control unit 11 includes a comparison unit 11A for comparing the obtained predetermined information with the detection unit 8 and/or an evaluation value obtained based on the predetermined information obtained by the detection with a predetermined comparison value, the predetermined information including at least Information of one or any combination of the position, size, inclination angle, and correlation value of the specific subject thermal image; in Embodiment 1, the value of the correlation of the thermal image data frame obtained by the detecting portion 8, Compare with the correlation value of the correlation. Note that the comparison value of the correlation may be a judgment value of the correlation degree prepared in advance (for example, corresponding to the subject identification information, which is stored in Table 3, for example, : ), , ; can be obtained without the pre-prepared correlation value, but according to the value of the correlation in the thermal image data frame, for example, the value of the correlation obtained by the first detection processing is used as the subsequent comparison correlation. The comparison value, and, when the correlation is detected to be greater than the comparison value, is updated.

 Further, the control unit 11 has a selection unit 11B that selects specific information on a predetermined thermal image data frame based on the comparison result of the comparison unit 11A. The specific information selected can be used for the prescribed processing to be experienced, such as analysis, recording, notification, and the like.

 The specific information related to the predetermined thermal image data frame is specific information related to one or more frames of the thermal image data frame in the multi-frame thermal image data frame of the temporary storage unit 2; for example, based on the comparison of the comparison portion 11A As a result, the specific information related to the thermal image data frame having the largest correlation is selected; but it is not limited to the frame of the thermal image data frame of the detected maximum correlation, for example, sub-optimal, or for example, detection may be selected. The frame before or after the timing of the frame of the maximum correlation, or the frame obtained by the multi-frame operation, or the specific information related to the thermal image data frame corresponding to the correlation of the specified contrast value is detected at the earliest. It may also be configured to select specific information related to multiple thermal image data frames, for example, to select specific information related to the first, second, and third three-frame thermal image data frames of the correlation, or to select the same hotness as the multi-frame correlation. Specific information like a data frame.

 The specific information is a thermal image data frame selected from a multi-frame thermal image data frame of the temporary storage unit 2, and data obtained by performing predetermined processing from a thermal image data frame selected from the multi-frame thermal image data frame, and the obtained specification is detected. The information, the evaluation value obtained based on the detection of the obtained predetermined information, based on one or more of the predetermined information obtained by the detection and/or the prompt information generated by the evaluation value.

 The data obtained by performing predetermined processing on the thermal image data frame selected from the multi-frame thermal image data frame, for example, data obtained by performing predetermined processing on the selected thermal image data frame, for example, extracted from the thermal image data frame. The specific subject thermal image, such as image data of the generated infrared thermal image, for example, converts the thermal image data frame into an array of analytical values such as temperature values, and the like.

 The predetermined information obtained by the detection, for example, includes at least one of a position, a size, an inclination angle, and a value of a correlation of a specific subject thermal image, or any combination thereof.

 The evaluation value obtained based on the detection of the obtained predetermined information is obtained by, for example, weighting the weighted coefficient based on the predetermined information obtained by the detection, or obtaining a rating for evaluating the thermal image quality based on a comparison table between the predetermined information and the evaluation value. value.

 The presentation information generated based on the detection and/or the presentation information generated by the evaluation value, for example, the specification information obtained by the detection and/or the evaluation value is converted into a prompt for percentage information that the user can easily understand.

 The selection unit 11B controls the selected specific information to be held or not held; the held specific information is held in a predetermined area of the temporary storage unit 2, and may be held (stored) in a storage medium such as the flash memory 3. Hereinafter, the selection unit 11B holds an example in which specific information such as a thermal image data frame is held in a predetermined area of the temporary storage unit 2.

The selection section 11B may hold the selected specific information at all times, or may hold it under a prescribed condition, for example, the currently selected specific information is maintained for a prescribed time; for example, until a thermal image data frame of a greater correlation is detected. Current specific information; for example, the selected specific information is always held until the subject identification information for detecting the comparison or the selected subject information is changed; for example, according to the user's instruction (eg, the user selects the display portion) A specific piece of information is displayed to determine the specific information that is maintained or not maintained. In addition, it may not be maintained, for example, transmitted to other external devices through the communication I/F 4; for example, undergoing other processing such as deleting after notification. „ , 1 π m 1/ . ugly, 3⁄4£丰郃11Β, 定邰2 疋憎Α3⁄4, 51 Specific information for subsequent selection of the 11B. The specified conditions, such as the specified time, for example, the specified quantity is detected. The thermal image data frame is, for example, based on the comparison result of the comparison portion 11A (when the correlation degree is greater than the correlation degree of the held thermal image data frame, etc.), such as an instruction of the user, etc. In addition, the previous maintenance can be performed. Specific information continues to be maintained.

 In the first embodiment, based on the comparison result of the comparison unit 11A, the selection unit 11B controls the selection, retention, and update of the specific information. For example, when the value of the correlation degree of the specific subject thermal image detected by the detecting unit 8 is greater than the comparison value of the correlation degree, the specific information such as the value of the correlation degree and the corresponding thermal image data frame is selected and held in the temporary storage unit. In the storage medium of 2; when there is specific information such as the correlation value and the corresponding thermal image data frame, the previous specific information will be replaced; until the subsequent hot image data frame with higher correlation can be replaced ( It is also possible to maintain a prescribed number of highly correlated thermal image data frames). Thus, specific information such as the value of the maximum correlation and the corresponding thermal image data frame is maintained. In addition, specific information that was previously maintained can be maintained.

 Preferably, the control unit 11 includes a notification unit 11C that notifies the specific information on the predetermined thermal image data frame selected by the selection unit 11B. The notification unit 11C preferably displays the notification information obtained by the currently selected specific information together with the infrared thermal image, the reference image, and the like obtained by the thermal image data frame continuously acquired by the acquisition unit. For example, the infrared thermal image obtained by the currently selected and held thermal image data frame (eg, after being reduced) is displayed together with the continuous infrared thermal image, reference image, and the like acquired by the imaging unit 1, and may be displayed simultaneously or separately. Notification information, such as the value of the correlation, the evaluation value, and the like. In addition, the dynamic infrared thermal image can also be switched to display a frozen image of the thermal image data frame.

 Wherein, when the selection unit 11B selects to hold the specific information related to the plurality of thermal image data frames, the notification unit 11C may notify one or more of the plurality of thermal image data frames, for example, the reduced infrared heat obtained by the plurality of thermal image data frames. It is displayed together with the continuous infrared thermal image acquired by the imaging unit 1.

 The notification information is obtained according to the specific information about the predetermined thermal image data frame selected by the selection unit 11B. For example, the value of the correlation can be converted into information that is easy for the user to understand, and displayed. The specified comparison table of the value of the correlation and the percentage, or the calculation method (such as the sum of the extracted specific object contour and the ratio of the overlap area of the contour T1 in the total area, divided by 200%, can be converted into The percentage value of the correlation is converted into the percentage value); it can also be other methods, such as directly displaying the value of the correlation, such as directly displaying the sum of the differences of the pixel values. Note that the displayed correlation degree is not compared with a predetermined comparison value (a judgment value representing whether or not a specific subject thermal image matches the subject identification information) indicating that a specific subject thermal image is detected or not. The information does not necessarily represent the detection of a specific subject thermal image (match) or not. For convenience of explanation, in the following, the value of the correlation degree, the evaluation value, and the percentage value converted by the comparison value are taken as an example, but in practice, it is not necessary to convert into a percentage value.

 Among them, the notification method can last for a specified time. Further, based on the control of the notification unit 11C, the display unit 10 can cause the display unit 10 to change the display content, the vibration of the vibrating member in the thermal image device 100, the light change of the indicator light, the sound of the sound component, and the analysis processing of the analysis component (and The display unit 10 displays the analysis result), and the diagnostic component performs a diagnosis (and causes the display unit 10 to display the diagnosis result), a reference image blinking display, a color change, or the like, and a change in one or more of the pseudo color change of the infrared thermal image; The way you can perceive it.

Further, the control unit 11 includes a recording unit 11E (not shown), and records the thermal image data frame selected and held by the selection unit 11B in the temporary storage unit 2 in the memory card 8 in response to a predetermined recording instruction. For example, the thermal image data frame is recorded to the memory card 8 in response to an instruction by the user to select a notified thermal image data frame, such as an automatic recording of timing. M ( ),

For example, the constituent data (dot matrix data or vector data) of the reference image associated with the object information stored in the storage medium is specified based on the user's selection of the subject information. The constituent data of the reference image associated with the object information is not limited to the object information, and the composition data of the reference image may be obtained by selecting, for example, a thermal image file from the storage medium; or, according to the thermal image device 100 The default configuration is to specify the constituent data of the reference image, for example, the data of the default detection area; in addition, for example, an area may be specified from the infrared thermal image displayed on the display unit, and the infrared thermal image of the area may be used as a reference image or the like. Specified way.

 Further, the control unit 11 is provided with a position setting unit 11G (not shown) for setting a position parameter (position, or also including a size, or a rotation angle) in which the reference image is located in the display unit. Preferably, the position setting portion 11G is configured to set a position parameter in which the reference image is located in the infrared thermal image; for example, according to the adaptive display region specified in the infrared thermal image, the centering is maximized in the adaptive region according to the calculated reference image The position parameter displayed to set the position parameter of the reference image in the infrared thermal image; for example, the reference image may be set according to the parameter attached to the reference image (for example, the position parameter in the infrared thermal image is reflected) The positional parameter in the infrared thermal image; or, the positional parameter of the reference image in the infrared thermal image may be set according to the configuration (centered, original size) of the thermal image device 100; or, according to the positional parameter input by the user .

 Operation unit 12: Various operations such as various instruction operations or input of setting information are input by the user, and the control unit 11 executes the corresponding program based on the operation signal of the operation unit 12. Referring to FIG. 2, the operation unit 12 is provided. The buttons for providing user operations include a record button 1, a focus button 2, a confirmation button 3, a play button 4, a menu button 5, a direction button 6, and the like; A speech recognition component (not shown) or the like is used to implement related operations.

 The control flow of the detection mode of the thermal image device 100 will be described with reference to Fig. 8, and the change of the display interface during the shooting will be described with reference to Fig. 6. In this application scenario, the user holds the thermal imaging device 100 to photograph the subject of the substation. The control unit 11 controls the overall operation of the thermal imaging device 100 and the control for executing a plurality of mode processes based on the control program stored in the flash memory 3 and various data used in the respective partial controls. After the power is turned on, the control unit 11 initializes the internal circuit, and then enters the standby shooting mode, that is, the imaging unit 1 captures a thermal image data frame, and the image processing unit 7 specifies the thermal image data frame captured by the imaging unit 1. The processing is stored in the temporary storage unit 2, and the infrared thermal image is continuously displayed in the form of a moving image on the display unit 10. In this state, the control unit 11 performs control thereof, and continuously monitors whether or not the processing is switched to another mode according to a predetermined operation. The shutdown operation, if any, enters the corresponding processing control. The control steps of the detection mode are as follows:

 Step A01, the display unit displays a dynamic infrared thermal image and a reference image, and the temporary storage unit 2 cyclically stores the thermal image data frame obtained by the imaging unit 1;

 Based on the control of the control unit 11, the display unit 10 displays a dynamic infrared thermal image and a reference image, and the temporary storage unit 2 cyclically stores the thermal image data frame obtained by the imaging unit 1.

 Specifically, in order to secure the photographing quality specification, the display mode of the reference image is selected by the predetermined operation of the operation unit 12, and the control unit 11 displays the subject indication information generated by the subject information based on the table 3 stored in the flash memory 3 Display unit 10 (not shown);

 Then, when the user selects "subject 1" according to the subject at the shooting scene, the "subject 1" displayed on the display portion 10 is selected by the operation portion 12;

The reference image specifying unit 11F determines the reference image T1 based on the user's selection, reads the constituent data of the reference image T1 from the flash memory 3, and transmits it to the temporary storage unit 2; and the position setting portion 11G sets the reference image T1 to be in infrared heat. ruler). , ,

Position parameter in the image. In addition, the positional parameter of the reference image T1 in the infrared thermal image may also be determined according to the specified adaptive display area or the position parameter specified by the user.

 The image processing unit 7 performs predetermined processing such as pseudo color conversion on the acquired thermal image data frame to obtain image data of the infrared thermal image, and the synthesizing unit obtains the image data of the reference image T1 according to the set predetermined size from the determined constituent data. Combining (overlapping) the image data of the generated infrared thermal image according to the set predetermined position, and storing the synthesized image data in the temporary storage unit 2;

 Next, the display control unit 9 displays the composite image on the display unit 10. As shown in FIG. 6(a), there is a difference in position and size between the subject thermal image and the contour image T1, and the user can take a picture based on the reference image. The subject is hot.

 Further, the temporary storage unit 2 cyclically stores the thermal image data frame obtained by the imaging unit 1.

 In step A02, the user may be confused with the alignment operation of the subject thermal image according to the contour image T1. To ensure the photographing quality and the operation is simple, the detection instruction is issued by the predetermined operation of the operation unit 12, and the control unit 11 detects that When the user's detection instruction (step A02: YES), the detection processing is entered.

 Further, the detection instruction is not limited to the user's issuance, and may be a predetermined timing or a trigger signal of an external device connected to the thermal imaging device 100, and the control unit 11 responds to the control detected by the detecting unit 8.

 In step A03, the feature registration unit registers the subject identification information. The feature registration unit determines the subject identification information for matching based on the user's previous selection of "subject 1", and here, the reference image T1 is assumed to be a template image for calculating the correlation degree. (In addition, the template data 301 can also be read from the flash memory 3 as the subject identification information for calculating the correlation). This step can also be completed before the A02 step, if the subject information is selected and completed.

 Next, in step A04, the thermal image data frame is read from the temporary storage unit 2;

 Step A05, detecting the window setting unit, and setting the detection window. For example, based on the upper left corner of the prescribed detection area G1, a detection window is first set;

 Step A06, a process of calculating the correlation between the thermal image data and the subject identification information in the detection window is performed. The detecting unit 8 extracts the thermal image data located in the detection window based on the detection window set by the detection window setting unit, and calculates the correlation between the two based on the contour image T1 registered by the feature registration unit. For example, according to the contour of the specific subject thermal image extracted by the thermal image data in the detection window, compared with the contour of the contour image T1, the sum of the ratios of the overlapping areas between the two in the respective total areas is calculated, thereby Get the value of the relevance.

 Further, at step Α07, the value of the obtained correlation degree is stored in the temporary storage unit 2.

 In step Α08, the detecting unit 8 judges whether or not the correlation has been calculated for all the detection windows when the detection window is set in the thermal image data frame. If there is no area in which the correlation has not been calculated (NO in step Α08), then returning to step Α05, the detection window setting unit shifts the position of the detection window by a predetermined number of pixels in a predetermined direction, and sets the position as the detection window. Next position, and repeat the subsequent processing.

 Further, when a frame portion similar to the template is searched for from the thermal image data frame, the detection processing similar to that described above is also performed for the enlargement and reduction and the detection window in which the detection window J1 is tilted by a predetermined angle.

If the correlation has been calculated for all the detection windows to be set in the thermal image data frame (YES in step Α08), the value of the maximum correlation detected in step Α09 (or the corresponding detection window) The positional parameter is held in a predetermined area of the temporary storage unit 2; the value of the correlation of the thermal image data frame is obtained. Aiu, . A04, repeat the subsequent processing. If yes, in step A1, the largest correlation degree is selected from the detected multi-frame thermal image data frames, and compared with the correlation value of the correlation degree;

 In step Al l, a comparison with the correlation value is compared;

 Wherein, the comparison value of the correlation degree may be a comparison value of the correlation degree of the initial preparation prepared in advance (for example, a judgment value for determining whether or not the specific subject thermal image is matched with the subject identification information is detected, as the initial value Correlation value of correlation).

 If it is less than the comparison value, it means that the thermal image data frame with the correlation degree is better than the comparison value is not detected; the process proceeds to step A13; if not, the process returns to step A01, and the display is a dynamic infrared thermal image, or may also be displayed. The portion 10 displays "the specific subject thermal image is not detected" to notify the user, as shown in Fig. 6 (a); then, the user changes the position of the shooting and adjusts the optical components of the thermal image device 100 and The shooting distance, imaging position, and angle between the thermal images of the subject, when the detection instruction is issued again, the subsequent processing is repeated.

 When the value of the correlation obtained by the detection is greater than the determination value, the process proceeds to step A12, and the specific information related to the thermal image data frame having the highest correlation (the plurality of frames with high correlation may be selected) is selected and held in the temporary storage unit 2 For subsequent processing. Further, the held specific information can be always held in the temporary storage unit 2 until the specific information that the selection unit 11B has not reselected.

 As shown in FIG. 6(b), the correlation degree of the detected thermal image data frame of the maximum correlation is 80%, and the selection unit 11B sets specific information related to the thermal image data frame, for example, the value of the correlation, the heat. The image data frame is held in the temporary storage unit 2. Alternatively, the notification unit 11C notifies that the infrared thermal image 601 obtained by the thermal image data frame is displayed together with the dynamic infrared thermal image and the reference image.

 The infrared thermal image 601 is not limited to display, and other methods may be used. As shown in FIG. 6(b), the value of the correlation is converted into information indicating the degree of matching, and the display is performed; for example, the value of the correlation is converted into a percentage. As an example (according to the specified comparison table of values and percentages of correlation degrees, or conversion), other methods may be used, such as directly displaying the value of the calculated correlation, such as directly displaying the ratio of the overlapping areas in the respective areas. And the value of and so on. Note that when it is not compared with a comparison value (a judgment value indicating whether or not a specific subject thermal image matches the subject identification information) of a specific subject thermal image, the information of the correlation degree displayed is It does not necessarily mean that a specific subject thermal image is detected. In addition, the display dynamic infrared thermal image can also be switched to display a frozen image of the thermal image data frame; in a preferred manner, the detected detection window having the largest correlation (or the position parameter of the object) Etc.) to make a notification. For example, the detected position of the position of the thermal image of the subject having the greatest correlation is detected in the frozen infrared thermal image. Or switching the display dynamic infrared thermal image to display the frozen image of the thermal image data frame, and then, in response to the user's instruction, switching back to the display state of the dynamic infrared thermal image, or the image obtained by the thermal image data frame and the dynamic image The state in which the infrared thermal image is displayed together. In addition, the infrared thermal image obtained by the thermal image data frame may not be displayed, and the prompt information may be displayed; or in a manner that various users can perceive by vibration, blinking of the indicator light, and the like.

At this time, if the user presses the record key, the thermal image data frame corresponding to the infrared thermal image 601 is subjected to predetermined processing (e.g., compression, etc.) to the memory card 8. Further, even if the prompt information or the infrared thermal image is not displayed, for example, the indicator light blinks, since the thermal image data frame is held in the storage medium such as the temporary storage unit 2, the user can press the confirmation button or When the key is recorded, processing such as display, recording, and the like is performed. In addition, the thermal image data frame can also be selected for direct recording without the user's operation. Further, it is also possible to perform processing such as analysis, diagnosis, and the like relating to thermal image capturing on the selected thermal image data frame. , n _ _ D - - _ m ^ . „ , 1 π ugly, W BE is set from 邰2 but Ί肓W 3⁄4£ 3⁄4i 11B is configured to indicate that multiple frames of thermal image data frames are maintained, then multiple The infrared thermal image obtained by the retained thermal image data frame is as shown in Fig. 6 (c), or is also sorted according to the degree of correlation. The user can select a thermal image data frame to be subjected to subsequent processing, and the like.

 Further, the comparison value of the correlation degree may not be prepared in advance. In this case, for example, the selection unit 11B selects the thermal image data frame or the plurality of frames having the highest correlation in the temporary storage unit 2 in accordance with the comparison result of the comparison unit 11A. Note that the thermal image data frame having the largest correlation degree selected does not necessarily represent a specific subject thermal image (match) or not when compared with the comparison value as a judgment as to whether or not the object identification information is identical.

 Step A13, judging whether to exit, if not exiting, returning to step A01, repeating the subsequent processing. Further, after the next detection processing, the specific information selected by the previous selection unit 11B can be configured to be continuously held, and the notification unit 11C can collectively display the specific information instructed by the selection unit when the detection processing is performed differently. Alternatively, the specific information obtained later may be replaced with the previous specific information.

 As described above, in the present embodiment, since the predetermined detection area is set, the user can easily understand the range of photographing, and when the instruction of the detection is received, the hot image data frame stored in the temporary storage unit 2 is detected. The frame with the highest correlation, and can maintain the specific information for subsequent recording, analysis and the like; can reduce the operation intensity of the visual matching alignment, and the ordinary user can easily grasp the shooting skill, the operation is simple, and can be reduced The processing speed of the processor is burdened, the cost of the thermal image device 100 is reduced, and the like, and is suitable for shooting a fast moving target.

 Further, the configuration of the notification portion 11C can be removed, for example, when a specific subject thermal image is detected, processing such as recording, analysis, and the like is performed.

 Example 2

 Embodiment 2 is different from Embodiment 1 in that the thermal image device 100 (infrared sorting device 100) has a comparison value updating portion 11D for updating the comparison value. Fig. 7 is a block diagram showing a schematic configuration of a thermal imaging device 100 of an example of the infrared sorting device 100 according to the second embodiment of the present invention. The same configurations as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted.

 Further, after the comparison value is updated, the comparison unit 11A detects the obtained predetermined information and/or the evaluation value obtained based on the detection of the obtained predetermined information, and compares it with the updated comparison value; For the adjustment of the shooting, the contrast value may be continuously increased, so that the user is more likely to be notified of the specific information of the thermal image data frame corresponding to the maximum correlation obtained in the multiple detection processing.

 The update condition of the comparison value is updated, for example, by the user's instruction; for example, the update is performed based on the predetermined time; for example, the comparison value is updated based on the comparison result of the comparison unit 11A.

 The comparison value for the update may be updated in sequence according to a plurality of comparison values prepared in advance; for example, comparison values of three correlation degrees are prepared, and when the correlation detected by the detection unit 8 is greater than the first comparison value, The subsequent comparison will be updated to the second comparison value, and when it is greater than the second comparison value, it will be updated to the third comparison value.

 The comparison value for updating may also be obtained according to the specified information obtained by the detection; for example, according to the detection unit 8 detecting the value of the correlation obtained, when the value of the correlation is greater than the comparison value of the correlation prepared in advance, The value of the obtained correlation is replaced with the comparison value for updating. The predetermined information includes at least one of a position, a size, a tilt angle, an analysis value, and a value of a correlation of a specific subject thermal image.

According to the comparison result of the comparison unit 11A, the comparison value is updated, or may be updated according to the predetermined information obtained by the detection, wherein there is no comparison value prepared in advance; for example, according to the detection unit 8 detecting the value of the correlation degree, when phase / " ( , , the value of the obtained correlation is updated accordingly by replacing the comparison value.

 Preferably, the notification unit 11C performs notification based on the information selected by the selection unit 11B regarding the specific thermal image data frame and/or the updated value of the comparison value.

 In addition, in the embodiment, the selection unit 11B is configured to replace at least the specific information related to the plurality of thermal image data frames held before the comparison value is updated, and at least replace the comparison result according to the comparison result of the comparison unit. One of the previously selected thermal image data frames is related to specific information. However, it is not limited to this, and it is also possible to maintain specific information before and after the update. Further, the notification unit 11C notifies the specific information on the thermal image data frame newly selected by the selection unit 11B.

 The control flow of the detection mode of the thermal image device 100 will be described with reference to Fig. 9, and the change of the display interface during the shooting will be described with reference to Fig. 10.

 Step A01-Step A02, similar to the step A01-A02 of Embodiment 1, the description is omitted;

 Step B03, similar to the step A03-A10 of the embodiment 1, detecting the correlation degree of obtaining the thermal image data frame of the multi-frame, and omitting the description;

 In step B04, comparing with the comparison value of the correlation degree; comparing the value of the maximum correlation degree with the comparison value; if it is smaller than the comparison value, it means that the comparison value is not detected and the previous comparison value is obtained or obtained before The maximum correlation of the thermal image data frame (as the updated comparison value); return to step A01, showing that no better thermal image data frame is detected; can also be configured to step B08, if not exited Go to A01. Then, the user repeats the subsequent processing by changing the position of the shooting and adjusting the shooting distance, imaging position, and angle between the optical component of the thermal image device 100 and the thermal image of the subject, and when the user gives an instruction again.

 Wherein, in a preferred manner, a comparison value of the initial correlation may be set (for example, a comparison value for determining whether there is a specific subject thermal image as a comparison value of the initial correlation), when the correlation obtained by the detection is obtained The value of the comparison is greater than the judgment value, and the correlation value of the detected specific subject thermal image is better than the prepared judgment value, and the judgment value is replaced with the comparison value obtained by the value of the currently detected correlation degree; The comparison value of the correlation is detected subsequently, so that whether a specific subject thermal image with higher correlation can be obtained subsequently. In this embodiment, it is assumed that the comparison value of the initial correlation of the thermal imaging device 100 is 72%, and the initial comparison value is a judgment value for judging whether a specific subject thermal image is detected, if the obtained thermal image data frame If the correlation is less than the comparison value, it means that the specific subject thermal image is not detected in the thermal image data frame; the effect is that when the user repeatedly fails to obtain the notification information, it means that the wrong photograph is taken. body.

 In addition, the comparison value of the correlation may not be prepared in advance. For example, when the value of the correlation of the first detected thermal image data frame is used as the value of the correlation obtained by the subsequent detection of the thermal image data frame. The comparison value, when the subsequent detection is greater than the comparison value, the comparison value is replaced.

 Here, whether or not the comparison value is greater than the comparison value is used as the basis for evaluating the correlation, but there are cases where the comparison value or the comparison value (predetermined value prepared in advance) is used as the evaluation correlation. Further, the contrast value may be a value of the correlation degree, or may be a value obtained by converting the value of the correlation degree or the like.

 When the correlation detected in step B04 is greater than the comparison value of the correlation degree, the process proceeds to step B05; wherein, if the comparison value of the correlation degree is not stored before, the value of the correlation degree obtained for the first time may be used as the correlation degree. value.

 Step B05, the comparison value updating unit 11D updates the comparison value of the correlation degree according to the detected value having the largest correlation degree, and the updated comparison value is used as a comparison of the comparison correlation degree of the subsequent thermal image data frame. value.

In step B06, the selection unit 11B holds the specific information such as the detected thermal image data frame corresponding to the value having the greatest correlation in the predetermined area of the temporary storage unit 2, and replaces the previous specific information (if any). In addition, you can keep the specified number , 3

Specific information such as values. Then, in step B07, subsequent notification, analysis, recording, diagnosis, and the like can be performed. Further, it is not limited to the specific information selected by the notification selecting unit 11B, and the updated value may be updated or the updated comparison value may be further notified.

 In step B08, it is judged whether to exit. If not, the process returns to step A01, and the subsequent processing is repeated. At this time, when the user again issues the detection instruction, since the comparison value of the correlation degree is updated, the correlation degree with the update is read and detected when the thermal image data frame is subsequently read and detected from the thermal image storage unit. The comparison values are compared, and, when the comparison value is greater than the correlation value, the held specific information is updated, and, in step B07, notification is made.

 In Embodiment 1, since only a comparison value (for example, a comparison value representing whether or not the subject thermal image matches the subject identification information) is compared, and the comparison value is not updated, subsequent shooting is performed. In the case, if the detection indication is issued, it is possible that the quality of the thermal image data frame is worse than before.

 In the second embodiment, the infrared thermal image 1001 as shown in FIG. 10(a) is detected first, because the correlation value (assuming the initial comparison value is 72%) is updated (updated to 85). %), therefore, when the correlation of the thermal image data frames detected in the temporary storage unit 2 is less than 85% after the detection instruction is issued again, the selection will not be selected, notified, or notified that "there is no better shot. The words "infrared thermal image". Then, when the detection instruction is issued, when it is detected that the infrared thermal image 1002 (95%) as shown in FIG. 6(b) is photographed, the selection is made and further notification is made; and, the selection section 11B always selects the maximum correlation. The specific information related to the thermal image data frame is maintained, so that the user can safely adjust the thermal image device 100 to pursue the thermal image of the best effect.

 It is to be noted that, in Embodiments 1 and 2, whether or not a specific subject thermal image is detected is not limited to a comparison between the value of the correlation and the comparison value of the correlation, and may be deformed into, for example, a specification obtained according to the detection. The comparison result of the information and/or the evaluation value obtained by the predetermined information and the predetermined comparison value is used as a basis for detecting whether or not the specific subject thermal image is detected.

 As described above, in the present embodiment, when the thermal image data frame whose correlation is higher than the comparison value is detected, the thermal image data frame is selected or notified, and the correlation is higher than before. When comparing the values, the comparison value can be continuously updated, and the specific information related to the selected hot image data frame is maintained, or the specific information held by the original is replaced; obviously, the notification is made according to the specific information selected by the selection unit. Subsequent processing such as analysis can improve the efficiency of the processing; it can achieve the operation difficulty of greatly reducing the visual matching alignment, greatly reduce the physical strength of the shooting, and improve the quality of the finally obtained thermal image data frame. It is easy for ordinary users to master this shooting skill. Of course, it is not necessary to achieve all of the advantages described above while implementing any of the products of the embodiments of the present invention.

 Moreover, in the field of infrared detection, since the position, size, tilt angle, and the like of a specific subject thermal image in the infrared thermal image are considered, corresponding to different photographing qualities, even if the correlation is high, if the above parameters are not ideal The quality of the acquired thermal image data frame is not necessarily high; therefore, it is preferable to consider factors such as a position, a size, an inclination angle, a correlation value, and the like of a specific subject thermal image in the thermal image data frame, for example, according to the above The factor is used to obtain the evaluation value (may be one or more), and compared with the specified comparison value, as a factor for selecting and notifying the specified thermal image data frame, to prompt the user to pay attention to the quality of the shooting, or to select the best. The thermal image data frame of the shooting quality is processed for subsequent processing.

 Example 3

The difference from the first embodiment and the second embodiment is that the thermal imaging device 100 (infrared sorting device 100) detects the plurality of stored in the temporary storage unit 2 based on the predetermined instruction based on the multi-frame thermal image data frame in the temporary storage unit 2. The predetermined information related to the specific subject thermal image in the frame thermal image data frame; wherein the predetermined information includes, for example, at least one of a position, a size, an inclination angle, and a correlation value of the specific subject thermal image. Information of any kind or combination. The control unit 11 has auxiliary information acquisition s; ι ΐΑ, the auxiliary information acquired by the information acquiring unit, the evaluation value obtained by the detecting unit 8 detecting the obtained predetermined information, the evaluation value obtained by the auxiliary information acquiring unit, and the predetermined information detected by the detecting unit 8 and One or more of the evaluation values obtained by the auxiliary information acquired by the auxiliary information acquisition unit are compared with the corresponding one or more comparison values; the selection unit 11B selects and specifies based on the comparison result of the comparison unit 11A. Specific information related to the thermal image data frame, when there are multiple comparisons, the selected specific information may be specific information related to one or more frames of thermal image data frames according to different comparison results; the notification portion 11C, based on the selection portion 11B The specific information related to the specified thermal image data frame is selected and notified. The comparison value update unit 11D is for updating the comparison value.

 In the field of infrared detection, since the position, size, tilt angle, etc. of a specific subject thermal image in the infrared thermal image are considered, corresponding to different shooting qualities, even if the correlation is high, if the above parameters are not ideal, The quality of the acquired thermal image data frame is not necessarily high; therefore, considering the position, size, tilt angle, and the like of the specific subject thermal image located in the thermal image data frame, as a factor for generating the notification, the user is prompted to pay attention to the shooting. Quality, or select the thermal image data frame of the best shooting quality for subsequent processing.

 The auxiliary information, for example, at least one of an analysis value, an ambient temperature, a background factor, a wind speed, a humidity, a distance, or any combination of information, or other auxiliary information acquired by the thermal imaging device 100 (including by using The setting is included in the range of information including other information relating to the predetermined thermal image data frame selected by the selection unit 11B and/or factors affecting the information notified by the notification unit 11C.

 In the field of application of infrared detection, depending on the above auxiliary information, the quality and importance of the obtained thermal image data frames are different, and there should be different conditions to cope with the comparison, selection, notification, etc. of the specified thermal image data frames. For example, when the obtained specific thermal image of the subject has an analysis value larger than the specified contrast value (for example, the threshold value of the defect), it means that the object has a defect, and then the user should pay attention to it. When the correlation is close, it is also preferable to select and notify the specific information related to the thermal image data frame whose analysis value exceeds the standard, which will immediately attract the attention of the user, which is significant for infrared detection; for example, considering the ambient temperature, background, wind speed, background Influencing factors such as the difference between the background and the thermal image of the subject, the thermal field distribution of the background, etc., in the case of close correlation, these influencing factors may lead to different thermal image quality and the value of subsequent analysis. To reduce, other influencing factors should be selected and notified to interfere with the thermal image data frame.

 The auxiliary information acquiring unit may acquire the auxiliary information according to the thermal image device 100 or a device connected to the thermal imaging device 100 or a component (not shown) of the corresponding function, for example, obtaining an analysis value by analyzing the component (analysis) The value may be a temperature value obtained by the analysis, and is not limited to the temperature value, for example, it may be an AD value, a color value in a pseudo color thermal image, a ratio of a specific image value, or a value calculated by a predetermined formula. Value, etc., the analysis value obtained by the analysis component can be used for all the pixels in the thermal image data frame or the pixels in the specific analysis area, the temperature is obtained by the temperature sensor, the humidity is obtained by the hygrometer, and the distance is obtained by the range finder. The distance between the thermal imaging device 100 and the subject, and the like. It is also possible to obtain, for example, historical data of the auxiliary information based on the above-described auxiliary information stored in advance in the storage medium; or to obtain the auxiliary information by comparing the auxiliary information acquired by the current measurement with the historical data of the auxiliary information stored in advance in the storage medium. The acquisition of various ancillary information is a technique well known to those skilled in the art.

Further, the comprehensive evaluation value may be obtained by specifying information and/or auxiliary information; for example, the specific information in the detected prescribed information may correspond to different coefficients, and other specified information in the detected prescribed information may be used. The evaluation value is obtained by combining the coefficient; for example, the weight of the different information may be used, and the evaluation value is obtained by weighting. The final evaluation value can be obtained by various calculation methods. u , 13 ( c ) 1301 is obtained, and the infrared thermal image 1302 is obtained according to the detection window with a window coefficient of 0.8, the evaluation value = the value of the correlation degree X window coefficient (the detection window can reflect the rough position and size), Therefore, even if the correlation of the infrared thermal image 1301 is smaller than the correlation of the infrared thermal image 1302, the evaluation value is rather high.

 For example, a comprehensive evaluation value can be obtained by the prescribed information and the auxiliary information. For example, an evaluation value obtained by integrating the position, size, inclination angle, analysis value, and correlation value of a specific subject thermal image is obtained, for example, a comprehensive evaluation value is obtained according to the following formula, and the comprehensive evaluation value = position X position weighting coefficient + size X size weighting coefficient + tilt angle X tilt angle weighting coefficient + analysis value X analysis value weighting coefficient + correlation value X correlation weighting coefficient; or, another preferred manner, according to the detected specified information and The obtained auxiliary information and the comprehensive evaluation value are compared to obtain an evaluation value.

 Further, it is also possible to obtain an evaluation value based on the predetermined information and the auxiliary information, and then, based on the predetermined information and/or auxiliary information in which the evaluation value is not participated, together with the obtained evaluation value, The comparison unit compares with the specified comparison value.

 The comparison value update unit 11D updates the comparison value according to the comparison result of the comparison unit 11A; and, when there are multiple comparison values, updates at least one of the corresponding comparison values; The comparison value is all updated. After the update, the comparison unit 11A is configured to perform subsequent detection of the predetermined information obtained by the detection unit 8, and/or based on the auxiliary information acquired by the auxiliary information acquisition unit, and/or by the regulation. The evaluation value obtained by the information and/or the auxiliary information is compared with a comparison value of the plurality of updates; wherein, when a part of the plurality of comparison values is updated, after the update, the update item with the plurality of comparison values The comparison value and the comparison value of the unupdated item are compared. Preferably, according to one of the optimal prescribed information obtained by the comparison unit comparison, or the optimal auxiliary information, or the optimal evaluation value obtained by the predetermined information and/or the auxiliary information obtained by the detection, at least one of A comparison value is updated.

 Wherein, the detecting unit 8 is configured to detect a plurality of pieces of predetermined information of a specific subject thermal image, and the comparing unit 11A detects the obtained predetermined information and/or the evaluation value obtained based on the detected predetermined information by the detecting unit 8 When compared with the predetermined plurality of comparison values, the selection unit 11B may select specific information about a plurality of thermal image data frames based on the result of the comparison, and the notification unit 11C may notify one or more of them. Preferably, the selection unit selects a value of the correlation degree and/or the predetermined information and/or the auxiliary information and/or the evaluation value (the evaluation value obtained by the predetermined information and/or the auxiliary information) based on the comparison result of the comparison unit. The specific information related to the thermal image data frame of the specified contrast value is maintained. The notification unit selects a value of the correlation degree and/or predetermined information and/or auxiliary information and/or an evaluation value based on the specific information related to the predetermined thermal image data frame selected and held by the selection unit (prescribed information and/or Or the evaluation value obtained by the auxiliary information is notified by the specific information related to the thermal image data frame of the specified comparison value.

 The control flow of the detection mode of the thermal imaging device 100 of the third embodiment will be described with reference to Figs. 11, 12, and in this example, three comparison values are arranged. The predetermined information (the value of the correlation) related to the specific subject thermal image in the thermal image data frame detected by the detecting unit 8, the predetermined information obtained by the detection, and the auxiliary information (analytical value) acquired by the auxiliary information acquiring unit. The obtained evaluation values are compared with the first, second, and third comparison values.

 The first contrast value is prepared in advance (in the present embodiment, the first contrast value of the correlation degree), and is used to determine whether or not there is a contrast value of the specific subject thermal image (representing the specific subject thermal image and the subject identification information) The judgment value of matching or not), the first comparison value is not updated.

a second comparison value (in the present embodiment, a second comparison value of the correlation degree), which is a comparison value of the correlation greater than the first comparison value, which is obtained according to the value of the correlation of the detected thermal image data frame, When a subsequent thermal image data frame detects a higher correlation value, the second comparison value will be updated to a higher value. , the ruler, , , , and the corresponding (for example, prepared) third comparison value, when the subsequent thermal image data frame detects a higher (better) comprehensive evaluation value, the third comparison value will be updated accordingly For higher values.

 Finally, the selection section 11B will select specific information relating to the second contrast value and/or the thermal image data frame superior to the third contrast value; facilitating subsequent processing of notification, analysis, diagnosis, recording, and the like.

 Step C01-Step C02, similar to the steps A01-A02 of Embodiment 1, the description is omitted;

The subsequent processing is repeated; it can also be configured to go to step C32, and if not, return to C01.

 When the correlation detected in step C04 is greater than the first comparison value, it proceeds to step C05.

 Step C05, the auxiliary information acquiring unit obtains auxiliary information such as an image related to a specific subject thermal image, for the thermal image data frame whose correlation degree is greater than the first comparison value and/or the thermal image data in the thermal image data frame detection window. Values, etc., such as control analysis components for analysis to obtain analytical values. Further, for example, when the detecting section 8 is configured to calculate the correlation by detecting the pixel ratio or the like, it is not limited to determining the positional parameter of the detected specific subject thermal image based on the positional parameter of the detection window, and in this case, Further extracting a contour of a specific subject from the detected detection window to obtain more precise position, size, tilt angle, and the like, and predetermined information related to a specific subject thermal image.

 In step C06, an evaluation value is obtained, and an evaluation value obtained by integrating the position, the size, the inclination angle, the analysis value, and the correlation value of the specific subject thermal image is obtained. For example, the comprehensive evaluation value is obtained according to the following formula, and the comprehensive evaluation value= Position X position weighting coefficient + size X size weighting coefficient + tilt angle X tilt angle weighting coefficient + analysis value X analysis value weighting coefficient + value of correlation degree X correlation weighting coefficient; or, another preferred manner, according to the detected The information is compared with the comprehensive evaluation value to obtain the evaluation value.

 Step C07, determining whether the thermal image data frames of the maximum correlation and the maximum evaluation value in the detected thermal image data frame are the same frame.

 If so (step C07: YES), proceed to step C08 to compare the evaluation value with the third comparison value.

 If it is less than the third comparison value (step C08: NO), then in step C09, the value of the correlation obtained by the detection is compared with the second comparison value; if not, then the process jumps to step C32, for example, the representative has previously detected Correlation, a thermal image data frame that is higher than the currently detected thermal image data frame. If so, in steps C10-C11, the comparison value updating portion 11D updates the second comparison value based on the value of the detected maximum correlation. Further, the selection unit 11B holds the specific information on the thermal image data frame in a predetermined area of the temporary storage unit 2, and replaces the previous specific information (if there is specific information about the previous thermal image data frame, and the previous thermal image) The correlation of the data frame is smaller than the currently detected thermal image data frame, and the evaluation value is not replaced when the thermal image data frame is not maximized, and in step C12, the correlation is greater than the second comparison value. The hot image is notified of specific information about the data frame.

 If the comprehensive evaluation value is greater than the third comparison value (step C08: YES), then in step C13, the value of the correlation is compared with the second comparison value;

If it is larger than the second comparison value (step C13: YES), at C14-C15, the comparison value updating portion 11D updates the second comparison based on the value of the maximum correlation detected by the thermal image data frame, the maximum comprehensive evaluation value. Value, third comparison value. Further, the selection unit 11B holds the specific information on the thermal image data frame in a predetermined area of the temporary storage unit 2, before replacing , T ^ · . - - _ 一疋憎), C16, — 升 丑 ST曰, WW But: Two contrast values of the thermal image data frame are related to the specific information to be notified.

 If it is smaller than the second comparison value (step C13: NO), at C17-C18, the comparison value updating portion 11D updates the third comparison value based on the detected comprehensive evaluation value of the thermal image data frame. Further, the selection unit 11B holds the detected specific information on the thermal image data frame corresponding to the largest comprehensive evaluation value in the predetermined area of the temporary storage unit 2, and replaces the previous specific information (if there is a previous thermal image data frame) Regarding the specific information, and the evaluation value of the previous thermal image data frame is smaller than the currently detected thermal image data frame, and the correlation is not maximized in the held thermal image data frame, the replacement is performed), and in step C19 And notifying the specific information related to the thermal image data frame whose comprehensive evaluation value is greater than the third comparison value.

 In step C07 (No), it is represented that in the detected thermal image data frame, the thermal image data frame with the highest correlation and the thermal image data frame with the largest evaluation value are different two frames (may also have multiple frames), Proceeding to step C20, the evaluation value of the thermal image data frame of the maximum evaluation value is compared with the third comparison value, as shown in FIG.

 If it is less than the third comparison value (step C20: NO), then in step C21, the value of the correlation of the thermal image data frame that detects the maximum correlation is compared with the second comparison value; if not, then skip to the step B32, representing the thermal image data frame that has previously detected the correlation and the evaluation value is higher than the currently detected thermal image data frame, the display portion will not display, or display the words that no better thermal image data frame is detected. If so, in steps C22-C23, the comparison value updating portion 11D updates the second comparison value based on the value of the detected maximum correlation. Further, the selection unit 11B holds the specific information on the thermal image data frame in a predetermined area of the temporary storage unit 2, and replaces the previous specific information (if there is specific information about the previous thermal image data frame, and the previous thermal image) If the correlation of the data frame is smaller than the currently detected thermal image data frame, and the evaluation value is not maximized in the held thermal image data frame, the replacement is performed), and in step C24, the correlation is greater than the second comparison value. The hot image is notified of specific information about the data frame.

 If the comprehensive evaluation value is greater than the third comparison value (step C20: YES), then in step C25, the value of the correlation is compared with the second comparison value; if it is greater than the second comparison value (step C25: YES), then at C26 -C27, the comparison value update unit 11D updates the second comparison value and the third comparison value based on the maximum correlation value detected by the thermal image data frame and the maximum comprehensive evaluation value. Further, the selection unit 11B holds the specific information on the thermal image data frame in a predetermined area of the temporary storage unit 2, replaces the previous specific information (if any), and in step C28, the correlation is greater than the second comparison value. The thermal image data frame and the specific information related to the thermal image data frame whose comprehensive evaluation value is larger than the third comparison value are notified (for example, two frames are simultaneously displayed).

 If it is smaller than the second comparison value (step C25: NO), at C29-C30, the comparison value updating portion 11D updates the third comparison value based on the detected comprehensive evaluation value of the thermal image data frame. Further, the selection unit 11B holds the detected specific information on the thermal image data frame corresponding to the largest comprehensive evaluation value in the predetermined area of the temporary storage unit 2, and replaces the previous specific information (if there is a previous thermal image data frame) Relevant specific information, and the evaluation value of the previous thermal image data frame is smaller than the currently detected thermal image data frame, and the correlation is not maximized in the retained thermal image data frame, and is replaced), and in step C31 And notifying the specific information related to the thermal image data frame whose comprehensive evaluation value is greater than the third comparison value.

Step C32, determining whether to exit the detection mode, if exiting, ending, if not exiting, returning to step C01, obviously, if specific information is selected, the notification information obtained by the selected specific information, the infrared thermal image, Reference image; repeat the above processing. Thus, when the thermal image data frame obtained by continuous shooting is cyclically stored in the temporary storage portion 2, when the response detection instruction is received, it will be superior to the second comparison value and/or better than the third comparison according to the detected prescribed information. The specific information related to the data frame of the value is selected and notified; facilitating subsequent notification, analysis, diagnosis, recording, maintenance, and the like. Wherein, whether the correlation degree of the detected thermal image data frame is greater than the first comparison value is a condition for further detecting the specified information, and , . i, different, there may be cases smaller or larger than the comparison value.

 The change of the display interface during shooting will be described with reference to FIG.

 As shown in FIG. 13(a), when the response detection indication indicates that the thermal image data frame whose correlation is greater than the first comparison value (assuming that the correlation percentage converted by the first comparison value is 72%) is displayed, the dynamic display is displayed. Infrared thermal image.

 In response to the first detection indication, as shown in FIG. 13(b), when the thermal image data frame whose correlation is greater than the first comparison value is detected for the first time, a dynamic infrared thermal image, a reference image, and the detected And the notification information is generated based on the specific information of the thermal image data frame stored by the selection unit 11B, for example, the thermal image data frame, the correlation value, and the evaluation value; the notification information includes the heat Like the infrared thermal image 1301 generated by the data frame, the correlation degree of the correlation value is 85%, and the evaluation value converted by the evaluation value is 80%. And, the comparison value updating portion 11D updates the second comparison value to, for example, 85%, and the third comparison value is, for example, updated to 80%; and, when the subsequent detection is not detected, the heat greater than the second comparison value and/or greater than the third comparison value is not detected. When the data frame is like a data frame, the display unit 10 will maintain the state of displaying the notification information such as the infrared thermal image 1301 and the dynamic infrared thermal image; and, because the infrared thermal image 1301 is the notification information generated by the currently newly obtained specific information, the bold border is formed. Remind users.

 In response to the second detection indication, as shown in FIG. 13(c), when a thermal image data frame larger than the second contrast value or the third contrast value is detected, the dynamic infrared thermal image and the detected thermal image data are displayed. Specific information about the frame, the specific information includes the infrared thermal image 1302 generated by the thermal image data frame, etc., wherein the correlation degree corresponding to the infrared thermal image 1302 is greater than the infrared thermal image 1301, and the evaluation value is smaller than the infrared heat. Like the 1301, the selection unit 11B holds the specific information about the two thermal image data frames; and the comparison value update unit 11D updates the second comparison value according to the correlation corresponding to the infrared thermal image 1302; The portion 11C causes the display unit 10 to display the notification information generated by the specific information obtained by the two different thermal image data frames. At this time, since the specific information such as the thermal image data frame corresponding to the infrared thermal images 1301 and 1302 is held in the temporary storage unit 2, the user can select the subsequent information from the information displayed on the display unit 10, such as the infrared thermal images 1301 and 1302. The corresponding thermal image data frame recorded or analyzed.

 In response to the third detection indication, and as shown in FIG. 13(d), when the detected correlation is greater than the second comparison value and the evaluation value is larger than the thermal image data frame of the third comparison value, the selection portion 11B will The specific information related to the infrared thermal image 1303 is maintained, or the specific information related to the infrared thermal images 1301, 1302 is deleted; and the comparison value updating portion 11D will correspond to the correlation (95%) corresponding to the infrared thermal image 1303 and The evaluation value (95%) updates the second and third comparison values; the notification unit 11C causes the display unit 10 to display the dynamic infrared thermal image, the reference image, and the specific information related to the detected thermal image data frame, The specific information includes an infrared thermal image 1303 generated by the thermal image data frame, and the like.

 In this way, the selection unit 11B selects and holds the value of the correlation degree and/or the specific information related to the thermal image data frame whose evaluation value is larger than the predetermined contrast value (the second comparison value, the third comparison value) based on the comparison result of the comparison unit. In the interface of the display unit 10, information obtained by notifying the thermal image data frame having the highest correlation degree and/or the highest evaluation value can always be displayed, which greatly contributes to the user's shooting.

As described above, in the present embodiment, not only the effect of the embodiment 1 but also the prescribed information and the auxiliary information based on the detected specific subject thermal image are set as the comparison factor, when the detection is further When the thermal image data frame is excellent, the selection unit selects and holds the specific information related to the thermal image data frame, and the comparison value update unit updates the comparison value accordingly, so that the selection of the more ideal thermal image data frame can be selected. Specific information; can achieve further difficulty in reducing visual alignment, improve the quality of thermal image data frames during shooting, and suggest the beneficial effects of specific states, which is easy for ordinary users to master. . ,

A product does not necessarily need to achieve all of the advantages described above at the same time.

 In addition, although three comparison values are exemplified, more comparison values may be used, corresponding to several different evaluation values and/or auxiliary information and/or prescribed information obtained by the detection, for example, by a specific subject thermal image. The evaluation value obtained by the position, size, and inclination angle, the evaluation value obtained from the analysis value, the ambient temperature, and the like.

 In addition, although the comparison value (three, or may be reduced to two) is exemplified in Embodiment 2, some of them are updated, some are not updated; but they may be configured to be all updated; or the comparison value may be removed. The structure of the part 11D is prepared in advance with a plurality of corresponding contrast values, all of which are not updated.

 In the third embodiment, the value and the evaluation value according to the correlation degree are introduced as an example, and a plurality of evaluation values are obtained based on the predetermined information detected by the detecting unit 8, based on the plurality of evaluation values and the corresponding comparison values. Comparing, to decide whether to perform selection and maintenance of specific information; or, to notify a plurality of thermal image data frames obtained according to different evaluation values; or, to also correlate the value of the correlation degree and the plurality of evaluation values in order or Priority level for notification. And preferably, the specific information related to the predetermined thermal image data frame of the latest selection (usually the correlation and/or the evaluation value is greater than the comparison value) is notified. In this way, the user is very convenient; for example, the position, size, inclination, and correlation value of the heat-fixed subject are used as evaluation factors, and it is convenient to obtain a high-quality thermal image data frame or a thermal image data frame required for a specific shooting. The value of the thermal image analysis value and the correlation value are used as evaluation factors to facilitate timely analysis of the subject's analysis.
