Description

Analysis area setting device, processing device, analysis area setting method, and processing method

Technical Field

The invention discloses an analysis area setting device, a processing device, an analysis area setting method and a processing method, and relates to the application field of thermal image detection.

Background

When the thermal image analysis of the subject is required, the user can set an analysis area for a point, line, plane, or the like of a specific portion of the thermal image of the subject to obtain an analysis result. In the prior art, for example, as shown in fig. 3 (a), an analysis area selection field XZ3 is displayed on a display screen of a thermal image capturing device, a user can select analysis areas such as points, lines, frames, etc. from the selection field XZ3 to form data, then position parameters of the analysis areas are set according to corresponding analysis positions of a subject thermal image in the displayed infrared thermal image, so as to set and obtain one or more analysis areas, and the thermal image capturing device can automatically arrange corresponding analysis area numbers such as S01, S02, S03 for the sequentially set analysis areas according to the sequence of operation of the user.

Editing an analysis mode according to the number of the analysis area to analyze the set analysis area; the analysis mode represents analysis calculation rules adopted for obtaining analysis results by analysis based on thermal image data determined by the analysis areas, for example, in temperature analysis, the highest temperature, the average temperature, the lowest temperature, the percentage content and the like are calculated, and the calculation relationship such as temperature difference and the like between the analysis areas can be included.

As shown in fig. 3 (a), according to the corresponding joints S01 and the upper and lower parts of the body casing corresponding to S02 and S03, the user can edit the analysis modes such as S01MAX, S02MAX-S03MAX according to specific industry criteria to obtain the analysis results of the analysis values; further, analysis patterns including diagnostic rules may be compiled such as: normal: s01MAX is less than or equal to 50 ℃ and S02MAX-S03MAX is less than or equal to 1 ℃; defects: s01MAX is less than or equal to 90 ℃ at 50 ℃ or less than or equal to 2 ℃ at 1 ℃ and S02MAX-S03MAX is less than or equal to 2 ℃; critical defect: 90 ℃ less than S01MAX or 2 ℃ less than S02MAX-S03MAX; the analysis result thus obtained determines the state of the subject.

The prior art brings a series of problems; one of the problems of the related art, for example, when the selected analysis region composition data or the set operation order is different, the positions of the subject corresponding to the analysis regions of the same number may be inconsistent; as shown in fig. 3 (b), the user sets analysis areas S01, S02, S03; however, in fig. 3 (a) and 3 (b), the analysis areas S01 and S03 having the same number are provided to correspond to different portions in the subject thermal image, and the analysis mode and the diagnosis rule edited in fig. 3 (a) are not applicable to the analysis area in fig. 3 (b).

The analysis areas with the same analysis area number may correspond to different parts in the thermal image of the shot object, so that a series of difficulties in subsequent analysis, such as difficulty in performing unified specification of analysis modes, diagnosis rules and the like on the shot objects of the same kind, difficulty in batch analysis of multi-frame thermal image data, and easiness in generating confusion of analysis diagnosis results and the like, are easily brought.

Therefore, in the prior art, in order to specify the setting of the analysis area, the user is currently required to manually adjust or set the number of the analysis area, and the number of the analysis area in fig. 3 (b) is adjusted, which is very complicated in operation and easy to make mistakes.

Or the rearrangement of the analysis mode based on the analysis region number in fig. 3 (b) is also a very cumbersome task; the analysis mode has large setting workload, and a user needs to be very familiar with the analysis mode of the thermal image of the object when setting the analysis mode, so that the requirement on the user is very high.

It is therefore appreciated that there is a need for an analysis area setting device that solves the problems of the prior art.

The thermal image data may be, for example, thermal image AD value data, image data of an infrared thermal image, or other data generated based on the thermal image AD value data, such as array data of temperature values.

Example 1

Embodiment 1 takes a portable thermal imaging device 13 with a photographing function as an example of an analysis area setting device. The structure of the thermal imaging device 13 of embodiment 1 is described with reference to fig. 1.

The thermal imaging device 13 includes an imaging unit 1, an image processing unit 2, a display control unit 3, a display unit 4, a communication I/F5, a temporary storage unit 6, a memory card I/F7, a memory card 8, a flash memory 9, an operation unit 10, and a control unit 11, and the control unit 11 is connected to the corresponding parts via a control and data bus 12, and is responsible for overall control of the thermal imaging device 13.

The imaging unit 1 is configured by an optical component, a lens driving component, an infrared detector, a signal preprocessing circuit, and the like, which are not shown. The optical component consists of an infrared optical lens for focusing the received infrared radiation to the infrared detector. The lens driving part drives the lens to perform focusing or zooming according to a control signal of the control part 11, or may be an optical part that is manually adjusted. Infrared detectors, such as infrared focal plane detectors of the refrigerated or uncooled type, convert infrared radiation passing through the optical component into an electrical signal. The signal preprocessing circuit includes a sampling circuit, an AD conversion circuit, a timing trigger circuit, and the like, and performs signal processing such as sampling in a predetermined period on electric signals output from the infrared detector, and converts the electric signals into digital thermal image data including, for example, binary data of 14 bits or 16 bits, through the AD conversion circuit. The thermal image data is not limited to the inherent resolution of the infrared detector, but can be lower or higher than the resolution of the infrared detector; the thermal image data is not limited to the analog signal output from the infrared detector, and may be obtained by predetermined processing, for example, based on a digital signal output from the infrared detector itself. In embodiment 1, the photographing section 1 serves as a thermal image acquiring section for acquiring thermal image data.

The image processing unit 2 performs predetermined processing on the thermal image data obtained by the imaging unit 1, and the processing of the image processing unit 2 such as correction, interpolation, pseudo-color, synthesis, compression, decompression, and the like is converted into processing suitable for data for display, recording, and the like. For example, the image processing unit 2 performs a predetermined process such as pseudo-color processing on the thermal image data obtained by the photographing unit 1 to obtain image data of an infrared thermal image. The image processing unit 2 may be implemented by a DSP, a microprocessor, a programmable FPGA, or the like.

The display control unit 3 generates and outputs a video signal for display, which is displayed on the display unit 4, from the image data for display stored in the temporary storage unit 6, based on the control performed by the control unit 11. A screen aspect ratio of 4 may be selected: 3; preferably, for clearly displaying the infrared thermal image and the part information, the subject information, and the like at the same time, a screen having an aspect ratio of 16: 9.

The communication I/F5 is an interface for connecting the thermal imaging device 13 to an external device such as a personal computer, a server, a PDA (personal digital assistant), another thermal imaging device, or a visible light imaging device according to a communication standard such as USB, 1394, or a network, for example, and exchanging data.

The temporary storage unit 6 is a volatile memory such as a RAM or a DRAM, and serves as a buffer memory for temporarily storing the thermal image data output from the imaging unit 1, and also as a working memory for the image processing unit 2 and the control unit 11, and temporarily stores the data processed by the image processing unit 2 and the control unit 11.

The memory card I/F7 is connected to the memory card I/F7 as an interface of the memory card 8, and the memory card 8 as a rewritable nonvolatile memory is detachably mounted in a card slot of the main body of the thermal imaging device 13, and data such as thermal image data is recorded under the control of the control unit 11.

The flash memory 9 stores a program for control and various data used for control of each section.

The operation unit 10: for the user to perform various operations, the control unit 11 executes a corresponding program in accordance with the operation signal of the operation unit 10. The operation unit 10 is described with reference to fig. 2, in which the recording key 1, the analysis key 2, and the like are provided as keys operated by the user; the touch panel 3, a voice recognition unit (not shown), and the like may be used to realize the relevant operation.

The control unit 11 controls the overall operation of the thermal imaging device 13, and stores a program for control and various data used for control of each part in a storage medium such as the flash memory 9. The control unit 11 is realized by CPU, MPU, SOC, a programmable FPGA, or the like, for example; the image processing unit 2 and the display control unit 3 may be processors integrated with the control unit 11.

The control unit 11 serves as a part information selecting unit for selecting part information. The location information may include, for example, information of a component, a shooting location, an angle, and the like; preferably, the device comprises at least a component, or a shooting part, or information of the component and the shooting part; in one example, the location information is, for example, component information of the subject such as a joint, a sleeve, a base, or the like; and the part information can also be subdivision of the component type, for example, the joint can be divided into a T-shaped clamp, a crimping pipe, a parallel groove clamp and the like; preferably, the location information may include various classification information suitable for industrial applications, such as voltage level, phase, etc.; in another example, the location information is, for example, shooting location information of the subject such as up, middle, down, etc.; in another example, the part information may also be combined information of the part information and the photographing part or angle, such as the upper part of the sleeve, the lower part of the sleeve, etc., for the parts involved in different analysis, comparison, etc., different part information should be prepared; various pieces of location information can be prepared in advance as needed. The location information may include information of one or a combination of letters, icons, numbers, etc.

In one example, the correspondence relation between the specific key and the part information may be preset, and the part information may be selected by operating the specific key (e.g., dial key).

Preferably, the control unit 11 is a part information display control unit for controlling the display of the mark representing the part information; the user can identify the position information represented by the identification. The location information may be stored in the storage medium in advance; preferably, the storage medium may store the location information and the analysis region composition data associated therewith, and the identification representing the location information and the analysis region composition data associated therewith may be displayed; the identification of the information related to the analysis region composition data can be an icon such as a thumbnail for representing the analysis region composition data, or can be a text expression such as a frame, a circle and the like of the analysis region composition data.

The storage medium may be a storage medium in the thermal imaging device 13, such as a nonvolatile storage medium as the flash memory 9 and the memory card 8, and a volatile storage medium as the temporary storage unit 6; other storage media may also be provided, such as storage media in other storage devices, thermal imaging devices, computers, etc., or network destination, connected to thermal imaging device 13, either by wire or wirelessly, such as by other devices, such as other storage devices, thermal imaging devices, computers, etc., connected to communication I/F5.

The control unit 11 serves as an analysis region setting unit for specifying the region information corresponding to the analysis region based on the selected region information;

information about the selected location information may be associated with a corresponding analysis region based on the selected location information; in one example, the analysis region may be selected and assigned and the corresponding location information may be added, and as shown in fig. 10, the analysis region S01 may be selected and the location information corresponding thereto may be selected and associated; for example, the analysis region S01 is associated with the analysis region S01 by selecting the corresponding site information "joint" from the displayed "joint", "upper sleeve portion" and "lower sleeve portion".

In another example, by selection of the location information, the analysis area is set according to the position parameter of the default analysis area and the analysis area composition data, and the selected location information is associated with the set analysis area; the position parameter is for example the position of the analysis area in the infrared thermography, or also the size, or also the rotation angle. The application, for example, allows the user to take a thermal image of the subject based on the displayed analysis area and the displayed location information.

Preferably, the analysis region setting unit sets the corresponding analysis region based on the selected region information.

In one example, the analysis region is set by selection of the location information based on the location parameter of its associated analysis region and the analysis region composition data; the application, for example, allows the user to take a thermal image of the subject based on the displayed analysis area and the displayed location information.

In a preferred embodiment, the analysis region setting unit sets the analysis region in accordance with the analysis region position parameter and/or analysis region configuration data set by the user based on the selected region information, and the set analysis region is associated with the information on the selected region information.

In one example, an analysis area is set according to the identification of the selected part information, the set analysis area is associated with the information related to the part information, and the analysis area is set according to the position parameter set by the user and/or the analysis area composition data; the location information is the location information corresponding to the selected identifier.

Preferably, the analysis area is set according to the position parameter set by the user based on the selected position information. When the analysis region configuration data is not associated with the part information, for example, default configuration data such as "frame" may be used, and the analysis region may be set according to the position parameter set by the user, for example, applicable to all the part information; when the analysis region configuration data is associated with the selected part information, the analysis region is set according to the position parameter set by the user, and the part information and the analysis region configuration data associated therewith may be stored in the storage medium in advance. In another example, the location information may be associated with a plurality of analysis area configuration data applicable to different application conditions, and the analysis area may be set according to a location parameter set by a user, which may be selected according to circumstances; in this case, the analysis region is set so that the position parameter of the analysis region in the infrared thermal image is obtained as a default position parameter or a position parameter of the analysis region associated with the selected region information, and the analysis region composition data is set by the user. For example, in one example, the positional parameters of the analysis region are obtained by selection of the region information, and the analysis region composition data is set by the user, so that the analysis region is set, and then, for example, the user performs photographing of a subject thermal image based on the displayed analysis region and region information.

The information related to the location information may be, for example, location information and/or a number corresponding to the location information (hereinafter, simply referred to as a location number), or the like; preferably, the correspondence between the location number and the location information has uniqueness. In this way, it may be convenient to write analysis patterns according to relatively simplified part numbers. In one example, the analysis pattern is composed according to the location information and/or the location number; in another example, the analysis pattern may be composed according to an analysis region number that includes location information and/or a location number.

As an example of uniqueness, the part number corresponds to the part information having uniqueness; for example, the specific part information is only associated with the specific part information, but the specific part information may be associated with a plurality of different part numbers. For example, the numbers which reflect different application conditions are corresponding, so that the user can select the operation conveniently, and different application conditions such as the day and night can be distinguished.

A preferable example of uniqueness is that the part numbers correspond to part information, and have uniqueness corresponding to each other (one-to-one correspondence), that is, only the specific part numbers correspond to the specific part information; the specific part number also corresponds to only the specific part information. In this way, it is easier to write analysis patterns according to the site numbers. For example, in the same thermal image, one piece of location information uniquely corresponds to only one location number, and one piece of location number also uniquely corresponds to only one piece of location information.

In a preferred example, the location number represents the identity information of the specific location information.

For the case where there is no influence on the processing such as analysis, there may be a plurality of identical part numbers corresponding to the same part information; for example, if the plurality of parts are identical in processing such as analysis, the order of arrangement of analysis regions is not related to the analysis, or a plurality of analysis regions arranged according to the plurality of parts may be present, have the same part number, and correspond to the same part information.

Uniqueness, when embodied, is understood to be applicable to a specific range of subjects; the specific range may be defined, for example, on the subject of the same model, the same type, the same jurisdiction, or the like, depending on the user application; different uniqueness ranges may be set as desired.

Further, the control unit 11 functions as an infrared thermal image display control unit for displaying an infrared thermal image generated from the acquired thermal image data. Preferably, the information is displayed on the same display screen as the optional location information.

Further, the control unit 11 is configured to record information about the selected region information, analysis region configuration data corresponding to the selected region information, and/or positional parameters of the analysis region, in association with the thermal image data, as a recording unit, based on the selected region information.

Further, the control unit 11 serves as a presentation unit for presenting the set analysis region and the corresponding site information. For example, by way of display; the rendering process is not limited to display, and may be rendered in various other renderable forms, such as "acoustic, optical, electrical," etc.

The specific operation and control flow of embodiment 1 will be described in detail below. The application scene, for example, photographs an object of a transformer substation. After the power is turned on, the control unit 11 initializes the internal circuit, and then enters a shooting mode in which the shooting unit 1 shoots and obtains thermal image data, the image processing unit 2 performs predetermined processing on the thermal image data obtained by the shooting unit 1, and stores the thermal image data in the temporary storage unit 6, and the control unit 11 performs control of the display control unit 3 so that the infrared thermal image is continuously displayed as a moving image on the display unit 4 and the selection field XZ4 of the part information identifier is displayed, as shown in fig. 4 (a).

Fig. 4 is a schematic diagram of a display interface for setting an analysis area for a subject thermal image. The control procedure of embodiment 1 is described with reference to the flowchart of fig. 5.

In step a01, the display unit 4 displays a dynamic infrared thermal image, and also displays a selection field XZ4 of the site information, and as shown in fig. 4 (a), the site information (including component information in this example) "joint", "upper part of the sleeve", "lower part of the sleeve", and the analysis region corresponding to each constitute data "circle", "frame". Preferably, the infrared thermal image and the location information are displayed on the same display screen. The user can select the position information according to the displayed object thermal image and the position information represented by the mark of the selection column XZ 4; wherein, the infrared thermal image can be frozen and displayed.

In another example, the location information may be selected stepwise, such as displaying "sleeve", and after selection, displaying "upper", "lower" options to be selected, from which the user may then select. The method is applicable to the case that the part information contains multiple information.

In step a02, the control unit 11 sets an analysis region according to the position parameter of the analysis region set by the user based on the selected region information.

When the part information does not have the analysis region composition data, for example, default composition data such as "frame" may be employed, which is applicable to all the part information; preferably, analysis region configuration data associated with the selected region information is used as analysis region configuration data associated with the set analysis region; then, the user can set the position parameter (such as position, size, rotation angle, etc.) of the analysis area in the infrared thermal image, and the numerical value of the specific position parameter can be input through the keys of the operation part 10, or the position of the set analysis area can be moved through the operation part 10 to input the position parameter; preferably, the location parameter is set by the touch screen 3.

Preferably, based on the selected region information, the control unit 11 associates the set analysis region with information on the region information; the information related to the location information may be location information and/or location number, etc., and the location number may be associated with the location information in advance, may be included in the location information, or may be generated based on the location information, etc.

In one example, the part number corresponds to the part information and is unique, so that the analysis mode can be conveniently edited according to the part number, and the analysis area related part information can be avoided.

In another example, when the part information corresponding to the part number does not have uniqueness, the analysis area is preferably associated with the part information, and the analysis mode may be edited in advance based on the part information.

Preferably, the selected part information and the part number are associated with the corresponding analysis area, so that the analysis mode is convenient to edit and is not easy to make mistakes. And facilitating subsequent batch processing such as retrieval and the like according to the position information; the site information and/or the site number may be used as the analysis region number of the analysis region or may be a component of the analysis region number.

For example, a predetermined area stored in a storage medium such as the temporary storage section 6 may be associated; preferably, the control unit 11 may display the set analysis region and the corresponding location information based on the location information corresponding to the analysis region; preferably, the analysis area number containing the position information and/or the position number is displayed near the analysis area (such as the upper, lower, left, right and the like of the analysis area), so that the user can conveniently identify the corresponding relation between the analysis area number and the analysis area number; analysis areas "joint J", "upper casing TS", "lower casing TS" as shown in fig. 4 (b). The analysis areas arranged in this way can be associated with the corresponding part information in advance, are irrelevant to the operation sequence arranged in sequence, and are not easy to make mistakes; in this way, the analysis pattern, the diagnostic rule, and the like can be arranged in advance in accordance with the information about the site information, such as the site number, and at the time of analysis, for example, the analysis can be performed in accordance with the arranged analysis pattern. In addition, the part numbers may be generated based on part information, for example, "J", "TS", "TX" may be generated based on part information "joint", "upper part of the sleeve", "lower part of the sleeve", and abbreviations such as pinyin abbreviations, respectively, and it is apparent that the analysis mode, the diagnostic rule, etc. may be pre-arranged based on part information about the pinyin abbreviations. The part numbers "J", "TS", "TX" correspond to the part information "joint", "casing upper part", "casing lower part" having uniqueness (one-to-one correspondence here), which facilitates editing of the analysis pattern according to the part number.

In another example, the analysis mode, the diagnostic rule, and the like may be arranged in advance based on the location information if there is no location number.

In another example, the analysis region-related region information or the related region number may be not used, but the analysis region-related region information may be divided into corresponding regions between the analysis regions by associating different analysis region configuration data with different prepared region information, for example, the different region information may correspond to a square, a circle, a triangle, a pentagon, or the like, and the analysis pattern may be arranged according to the different types of the analysis region configuration data; in this case, the analysis region configuration data itself has a function of distinguishing the corresponding part information, and as a specific example, information about the selected part information may be represented.

Considering that a plurality of object thermal images may exist in the same infrared thermal image, preferably, the analysis area number may be obtained according to the location information and/or the location number and the setting sequence number, and the analysis area number and the set analysis area are stored in an associated manner; the arrangement order number may be determined, for example, by selecting the same location information and arranging the order of analysis areas. As shown in fig. 6, the analysis area numbers (J1, TS1, TX 1) set by the two object thermal images IR1, IR2, IR1 are obtained by combining the chinese phonetic abbreviations according to the selected location information with the setting order number "1", representing that the user first performs the selection and the analysis area setting of the location information for the object thermal image IR1, the analysis area numbers (J2, TS2, TX 2) set by the IR2 are obtained by combining the chinese phonetic abbreviations according to the selected location information (or the location information may also be adopted) with the setting order number "2", and it is obvious that it is very convenient to set the analysis areas by a plurality of object thermal images, one object thermal image is set first, and then another object thermal image is set, so as to conform to the setting operation habit of the user. Moreover, the set analysis area is convenient for analysis by adopting an analysis mode arranged according to the information related to the position information and the like; wherein analysis of one of the subject thermal images IR1 can be performed according to the laid-out setting order numbers such as "1"; and the comparison analysis of the same part among different object thermal images is conveniently carried out according to different setting sequence numbers. Various binding site information can be used to number analysis areas to achieve the purpose of distinguishing sites from subject thermal images.

Therefore, the technical problem of the existing analysis area setting is solved, the set analysis area is standard and is simple to operate, specific parts correspond to corresponding part information, and the problems caused by different setting orders are solved.

Further, the recording unit is provided with a recording unit for recording the prescribed recording information in association with thermal image data and/or data obtained after prescribed processing of the thermal image data;

preferably, the predetermined record information includes information on the selected region information and information on the associated analysis region.

The information about the analysis region includes, for example, analysis region configuration data and/or a positional parameter of the analysis region. The position parameter includes position, size, rotation angle, etc. When one item is associated with the default or selected location information of the thermal imaging device 13, only the other item set by the user may be recorded; at the time of the subsequent analysis, the analysis area may be set according to one of the items associated with the default or selected part information of the thermal imaging device 13 (the processing device at the subsequent analysis should be prepared with the information, for example, the information of one of the items associated with the default or part information of the thermal imaging device 13) in combination with the recorded other item. Similarly, when the two items are associated with default or selected part information, information about the analysis area may not be recorded;

When both items are set by the user, the position parameters of the analysis area are preferably recorded, the analysis area composition data can be determined by the processing device, and the subsequent manual setting can be avoided because the flexibility and the tolerance of the analysis area composition data are large (such as the influence of a normal frame or a circle on an analysis result is not large). Further preferably, the set analysis region configuration data and the positional parameters of the analysis region are recorded.

In one example, when a record key is pressed, the information on the part information, the configuration data of the analysis area related to the corresponding analysis area and/or the position parameter of the analysis area are controlled, and the data-related record obtained after the predetermined processing is performed on the thermal image data and/or the thermal image data is recorded, for example, a thermal image picture file is generated and recorded in the memory card 8, and when the thermal image picture file is analyzed later, the analysis area corresponding to the part information can be analyzed according to the analysis mode corresponding to the pre-prepared part information by analyzing the predetermined record information related to the thermal image picture file; the analysis area can be obtained according to analysis area composition data associated with the thermal image file and/or position parameters of the analysis area; it is apparent that, in one example, when a plurality of thermal image picture files are associated with analysis areas corresponding to the same location information, the analysis mode corresponding to the location information may be applied to the analysis of the plurality of thermal image picture files.

The recorded thermal image data and/or data obtained after predetermined processing of the thermal image data, for example, thermal image data (frames) obtained by reading a signal by an infrared detector in response to the timing of the recording instruction; for example; in response to the timing of the recording instruction, predetermined thermal image data (frames) among thermal image data of a plurality of frames temporarily stored in the temporary storage section 6; for example, the thermal image data in the above case is data obtained after a predetermined process (one or more of a predetermined process such as correction, interpolation, pseudo color, conversion to a temperature value, pixel reduction, compression, analysis, and the like) is performed; for example, thermal image data of a prescribed number of frames is recorded; for example, thermal image data (frames) obtained by subjecting thermal image data of a predetermined number of frames to a predetermined process, such as integrating thermal image data of a plurality of frames stored in the temporary storage section 6, to obtain thermal image data of one frame after the process; for example, one or more of the infrared data obtained in these cases may be used, such as the temperature value of each pixel obtained by simultaneously recording the thermal image data and the image data of the infrared thermal image.

Specifically, in response to a recording instruction operation by the operation unit 10, the control unit 11 controls the infrared detector to read a signal to obtain thermal image data, causes the image processing unit 2 to perform predetermined thermal image data compression processing on the thermal image data, or causes the thermal image data to perform predetermined processing such as correction and interpolation, and then performs compression processing, causes the temporary storage unit 6 to correlate predetermined recording information with the compressed thermal image data, generates a thermal image file, and records the thermal image file on the memory card 8, thereby ending the processing. In addition, the compression may be performed after the information is added.

Preferably, the thermal image file name can be generated according to the selected position information so as to facilitate subsequent analysis and processing; preferably, the recording unit has a file name generating unit for generating a file name of the thermal image file, and the file name of the thermal image file generated includes information about the location information; for example, the thermal image file name of the key separation which can be generated is selected by the position information joint, the upper part of the sleeve and the lower part of the sleeve: joint-casing upper-casing lower. Jpg; further, a file name, for example, joint-sleeve upper-sleeve lower-20130207. Jpg is generated as in combination with the photographing time information "20130207". Keyword separation can facilitate computer reading and rapid analysis of subsequent batch processing.

The association recording process may record predetermined recording information in an information file or an index file related to the thermal image file, and the control unit 11 may generate the information file or the index file. The essence of the associated record is to record the location information and analysis area related information needed for facilitating subsequent batch analysis.

The present invention is not limited to the thermal image picture file, and in another example, the thermal image recording section continuously records the thermal image data obtained by photographing to generate a thermal image video file containing a plurality of frames of thermal images, wherein when a recording instruction of the associated prescribed recording information is given, the control section 11 controls the thermal image data obtained by reading the signal from the infrared detector to perform compression processing so that the prescribed recording information in the temporary storage section 6 and the compressed thermal image data are associated and stored in the thermal image video file, wherein the frame time sequence position of the frame thermal image data may be associated with the prescribed recording information and stored in the index area of the thermal image video file, and then the subsequent dynamic recording processing is continued.

And the part information and the like are recorded in association with the thermal image data and the like, so that the subsequent batch analysis is convenient.

It should be noted that the displayed subject indication information may generally include only subject identity information such as subject location, type, and the like, so that the user can recognize the subject information at the time of photographing, and it is not necessary to display other information that may be included in the subject information.

Preferably, a wide screen (such as a 16:9 wide screen) is adopted, so that prompt information such as object indication information and the like can be displayed together with the infrared thermal image, and can be not overlapped on the infrared thermal image (usually 4:3); in addition, the subject instruction information may be superimposed on the infrared thermal image.

When the user selects the subject instruction information "subject 1", the region information selection field XZ72 is displayed, and the region information "joint", "upper sleeve", "lower sleeve" associated with the "subject 1" and the analysis regions corresponding to the region information are displayed to form a data "circle", "frame", and "frame", respectively.

As shown in fig. 7 (c), the user can select the site information from among them to set the analysis region.

The set analysis area is further standardized and is simple to operate, and the beneficial effects of being difficult to miss the analysis part of the object are achieved. The analysis area may be associated with information related to the location information (e.g., location information and/or a location number corresponding to the location information); preferably, the set analysis area may be associated with information about the selected subject information (for example, complete information of the subject information, or specific keywords, IDs, etc. therein), information about the location information, so that subsequent collating analysis may be facilitated; the information on the selected subject information and the information on the region information may be the analysis region number or a component of the analysis region number.

Preferably, the analysis area number may be generated based on the location information and/or the location number in combination with the order number of the arrangement; the method is suitable for subsequent analysis of the subject thermal images of a plurality of subjects in the same infrared thermal image. The selected subject information and the information related to the region information may be the analysis region number or a component of the analysis region number; accordingly, in order to schedule the analysis mode, the analysis mode may be scheduled by associating object information, site number, or the like with the analysis mode in advance, or by using the object information, site number, or the like as the analysis region number or a constituent part thereof. The purpose of further accurate analysis according to different subjects (even if the types are the same) can be achieved.

And, the part information is selected and the analysis area is correspondingly set, if the record instruction is given, the recording part is used for associating the specified record information with thermal image data and/or data obtained after the thermal image data is specified and processed; the predetermined record information includes information on the selected subject information, information on the selected region information, and information on an analysis region associated with the information on the selected region information.

Further, the recording unit preferably includes a file name generating unit configured to generate a file name of the thermal image file, the file name of the thermal image file including information on the selected subject information; for example, the generated thermal image file name: subject 1.Jpg; further, a file name such as subject 1-joint-sleeve upper-sleeve lower is generated in combination with the site information; further, generating a file name, for example, subject 1-joint-sleeve upper-sleeve lower-20130207. Jpg, in combination with shooting time information "20130207" facilitates reading the above information at the time of subsequent batch analysis.

As described above, by selecting the subject information, displaying the identification of the region information based on the region information associated with the subject information or displaying the identification including the region information and the analysis region configuration data based on the analysis region configuration data associated with the region information, the set analysis region is further standardized and the operation is simple, and when the information about the subject information, the information about the region information, the information about the analysis region, and the like are recorded in association with the thermal image data or the like, the subsequent batch analysis is further facilitated.

In another example, there may be no predetermined association between the subject information and the region information, and there may be no predetermined association between the region information and the analysis region configuration data and/or the analysis region position parameter; although the user's operation is somewhat cumbersome. In this case, for example, the object information, the selected region information, and the analysis region associated with the region information are recorded in association with the thermal image data, and the subsequent analysis and batch processing can be facilitated.

Techniques for analyzing specific processes by thermal imaging are well known to those skilled in the art, and the description thereof is omitted.

The analysis mode can be a general analysis mode and can be applied to all set analysis areas.

Preferably, the analysis pattern associated with the location information may be prepared in advance based on the analysis pattern information associated with the location information; in one example, the location information and the associated analysis mode thereof may be stored in the storage medium in advance to be applied to the analysis region set corresponding to the location information; in another example, the site information and the analysis region configuration data associated therewith, the analysis pattern corresponding to the analysis region configuration data, and the like may be stored in the storage medium in advance so as to be applied to the analysis of the analysis region obtained from the analysis region configuration data, and this applies to the case where a plurality of analysis region configuration data of different applications are associated with the same site information. In yet another example, the location information may be associated with a plurality of analysis modes suitable for different application conditions, and may be selected according to circumstances.

The corresponding analysis pattern relating to the analysis may be determined from the analysis pattern associated with the various factors determining the analysis region configuration data and/or the analysis region position parameters; for example, the analysis pattern obtained is based on the position rule related to the position parameter of the analysis area or the analysis pattern information associated with the position parameter.

An example of the analysis pattern and the analysis region configuration data associated with the storage region information stored in the storage medium will be described with reference to the table shown in fig. 12.

The user can know which part is defective based on the presented analysis result. When the analysis mode with the diagnosis rule is adopted, the alarm can be given according to the specified condition, and the part information is not presented.

The specific operation and control flow of embodiment 4 will be described in detail below.

Fig. 11 is a schematic diagram of a display interface for performing analysis region setting and analysis on a subject thermal image. The control procedure of embodiment 1 is described with reference to the flowchart of fig. 13.

In step C01, the display unit 4 displays the dynamic infrared thermal image, and also displays the selection field XZ11 of the site information, and as shown in fig. 11 (a), the site information "joint", "upper sleeve", "lower sleeve" and the analysis regions corresponding thereto constitute data "circle", "frame", respectively. Preferably, the infrared thermal image and the location information are displayed on the same display screen. The user can identify the position information represented by the mark of the selection column XZ11 according to the displayed object thermal image to select the position information;

in step C02, the control unit 11 sets an analysis region according to the position parameter of the analysis region set by the user based on the selected region information.

The control unit 11 correlates the information on the set analysis region with the information on the selected site information, and the information on the site information may be site information and/or site number, etc., as shown in fig. 4 (b) as analysis region "joint J", "upper sleeve TS", "lower sleeve TS". The part numbers J, TS and TX of the analysis areas arranged in the way can be associated with the corresponding part information in advance, are irrelevant to the operation sequence arranged in sequence, and are not easy to make mistakes; thus, at the time of analysis, for example, analysis can be performed according to the analysis mode as laid out in fig. 12.

And C03, analyzing the acquired thermal image data according to the analysis mode associated with the position information to obtain an analysis result. Specifically, for example, thermal image data determined by the analysis areas J, TS, TX (for example, in the analysis areas) is extracted and analyzed, and analysis results are obtained by analyzing the thermal image data according to the analysis pattern corresponding to each analysis area.

Obviously, the diagnostic result may also be displayed near the analysis value.

Therefore, the technical problem of the existing analysis area setting is solved, and the set analysis area is standard and has the advantage of simple operation. In addition, when the position numbers are irrelevant to the operation sequence which is set in sequence, the analysis is convenient according to the pre-arranged analysis mode; even if a plurality of object thermal images exist in the same thermal image data, the corresponding analysis area numbers can be arranged according to the mode of the position information and the sequence numbers, so that the marking and the distinguishing of analysis positions can be performed; accordingly, the analysis of a plurality of subject thermal images can also be performed using corresponding pre-programmed analysis modes. Thereby solving the prior art problems. In addition, if the analysis mode is pre-associated with the position information, the requirement on the user is reduced.

When the record key is pressed, the recording of the part information, the corresponding analysis result, and the like in association with the thermal image data is controlled, for example, a thermal image file is generated and recorded in the memory card 8, and when the thermal image file is subjected to subsequent analysis and arrangement, further analysis can be performed based on the analysis result and the like corresponding to the part information.

In one example, the analysis unit includes an analysis unit, an analysis region setting unit, and an analysis unit

For example, the multi-frame thermal image data is searched for according to the state property (critical defect) of the specific part, and thermal image data (frame) with the most serious defect of the specific part is obtained. For example, before the user overhauls, the user can obtain the search result of critical defects of the joint part of the shot object of the specific equipment type by selecting the equipment type and the part information joint, so as to reasonably arrange the rush repair plan.
