And, selection portion 11B, the customizing messages interim storage part 2 being kept for condition according to the rules, is updated to the customizing messages of the follow-up selection of selection portion 11B.So-called defined terms, for example official hour, for example detect the thermal-image data frame of specified quantity, for example, such as, according to comparing section 11A comparative result (obtained the degree of correlation and be greater than the situations such as the degree of correlation of kept thermal-image data frame), user indication etc.In addition, also the customizing messages being kept before can be continued to keep.
In embodiment 1, the comparative result of the 11A of portion based on the comparison, the control that selection portion 11B selects, keeps and upgrade customizing messages.While being greater than the correlative value of the degree of correlation as the value of the degree of correlation of the specific shot body heat picture detecting when test section 8, the customizing messages such as value and corresponding thermal-image data frame of selecting this degree of correlation is remained in the storage mediums such as interim storage part 2; In the time having the customizing messages such as value and corresponding thermal-image data frame of the degree of correlation before, by the customizing messages before replacing it; Have the higher thermal-image data frame of the degree of correlation during until follow-up, can be replaced (the higher thermal-image data frame of the degree of correlation that also can keep specified quantity).Like this, kept as the customizing messages such as value and corresponding thermal-image data frame of the maximum degree of correlation.In addition, also the customizing messages being kept before can be continued to keep.
Note, selection portion 11B is not limited to select the relevant customizing messages of a frame thermal-image data frame of optimum (for example degree of correlation maximum), for example, also can select suboptimum, or select multiframe computing to obtain that frame, or also can be configured to select the relevant customizing messages of multiple thermal-image data frames, for example select the three frame thermal-image data frames relevant customizing messages of storage (maintenance) degree of correlation first, second, third, also may preserve the customizing messages of the thermal-image data frame that the three frame degrees of correlation are the same.
In addition, control part 11 has the correlative value renewal 11C of portion, for condition according to the rules, correlative value is upgraded; And after correlative value is upgraded, described comparing section 11A, detects the provisioning information obtaining and/or the evaluation of estimate obtaining based on detecting the provisioning information of acquisition to test section 8, compares with the correlative value after upgrading.
The update condition of correlative value, for example user's indication is upgraded; For example, according to the comparative result of comparing section 11A, correlative value is upgraded; For example time according to the rules upgrades.
According to the comparative result of comparing section 11A, correlative value is upgraded, can be according to pre-prepd multiple correlative values, upgrade successively; For example prepare the correlative value of three degrees of correlation, when the degree of correlation detecting when test section 8 is greater than first correlative value, follow-uply will be updated to second correlative value, in the time being greater than second correlative value, will be updated to the 3rd correlative value.
According to the comparative result of comparing section 11A, correlative value is upgraded, can be also to upgrade pre-prepd correlative value according to detecting the provisioning information obtaining; For example detect according to test section 8 value that obtains the degree of correlation, in the time that the value of this degree of correlation is greater than the correlative value of the pre-prepd degree of correlation, upgrade replacing correlative value according to the value of the obtained degree of correlation.
According to the comparative result of comparing section 11A, correlative value is upgraded, can be also to carry out self according to detecting the provisioning information obtaining, wherein, there is no pre-prepd correlative value; For example detect according to test section 8 value that obtains the degree of correlation, in the time that the value of this degree of correlation is greater than the correlative value (for example, before the value of detected degree of correlation maximum is used as correlative value) of the degree of correlation, corresponding the value of obtained degree of correlation replacement correlative value is upgraded.
In addition, control part 11 possesses notification unit 11D, and the information that the customizing messages that thermal-image data frame selected based on selection portion 11B and regulation is relevant and/or correlative value are upgraded, notifies.For example, selected and that keep and the relevant customizing messages of thermal-image data frame regulation based on selection portion 11B, the announcement information that customizing messages is obtained shows jointly with the infrared thermal imagery of the thermal-image data frame acquisition that acquisition unit is obtained continuously.Preferably, the infrared thermal imagery that the thermal-image data frame that the announcement information current selected customizing messages being obtained and acquisition unit are obtained continuously obtains shows jointly.The continuous infrared thermal imagery that infrared thermal imagery and the shoot part 1 for example current thermal-image data frame selected and that keep being obtained obtains shows jointly, in addition, and also can the while or show separately other announcement information, the value of for example degree of correlation, evaluation of estimate etc.In addition, also Dynamic IR thermal imagery can be switched to the freeze frame that shows this thermal-image data frame.
Wherein, in the time that selection portion 11B selects and kept the relevant customizing messages of multiple thermal-image data frames, notification unit 11D can be to one of them or multiple notice, and for example, the continuous infrared thermal imagery that the infrared thermal imagery that multiple thermal-image data frames are obtained and shoot part 1 obtain shows jointly.
Wherein, the relevant customizing messages of thermal-image data frame selected according to selection portion 11B and regulation, obtains announcement information, for example, the value of the degree of correlation can be scaled to the information that user understands of being convenient to of the similar degree of signal, shows; For example, according to the table of comparisons of the regulation of the value of the degree of correlation and number percent, or the mode of calculating is (as the specific shot body profile being extracted and the profile T1 overlapping area ratio sum in the total area separately, divided by 200%, can be scaled the percent value of the degree of correlation) value of the degree of correlation is scaled to percent value); Also can be other mode, the value that for example directly will calculate the degree of correlation shows, as the difference of direct display pixel value and numerical value etc.Note, in the time not detecting that with representative specific shot body heat picture whether regulation correlative value (representing the judgment value whether specific shot body heat picture mates with subject identifying information) contrasts, the information of the shown degree of correlation might not represent whether specific shot body heat picture (coupling) detected.For ease of explanation, hereinafter, using the percent value of the value of the degree of correlation, evaluation of estimate, correlative value conversion as example, but in reality, must not be converted into percent value.
Wherein, the mode of notice can continue official hour.And, based on the control of notification unit 11D, can make display part 10 produce the vibration of the vibrating mass in variation, the thermal imagery device 100 of displaying contents, the light variation of pilot lamp, the sound of sound components, the analyzing and processing (and making display part 10 display analysis results) of analysis component, deagnostic package is diagnosed the color one or more of variation changing etc. of the puppet of (and making display part 10 show diagnostic result), reference picture flickering display or variable color etc., infrared thermal imagery; As long as the appreciable mode of user all can.
In addition, it is not shown that control part 11 has recording unit 11E(), the record indication of response regulation, is recorded to storage card 8 by thermal-image data frame selected selection portion 11B and that remain in interim storage part 2.For example respond the indications such as the selection of user to notified thermal-image data frame, the indications such as for example automatic record of timing, are recorded to storage card 8 by described thermal-image data frame.
In addition, it is not shown that control part 11 possesses reference picture specifying part 11F(), be used to specify will with the composition data of the common reference picture showing of infrared thermal imagery; For example, the composition data of the reference picture of the subject information association based on storing in storage medium (dot array data or vector data), the selection according to user to subject information, specifies the composition data with the reference picture of subject information association; Be not limited to by subject information, also can from storage medium, select such as thermal imagery file etc. to obtain the composition data of reference picture; In addition, also can, according to the default configuration of thermal imagery device 100, carry out the composition data of designated reference image, for example the data of the surveyed area of acquiescence; In addition, appointed area the infrared thermal imagery that also can for example show from display part, and using the infrared thermal imagery in this region as the mode with reference to various appointments such as images.
In addition, it is not shown that control part 11 possesses position setting unit 11G(), for being set, reference picture is positioned at the location parameter (position, or also comprise size, or also comprise the anglec of rotation) of display part.Preferably, setting unit 11G in position is positioned at the location parameter of infrared thermal imagery for reference picture is set; For example, according to the self-adaptation viewing area stipulating in infrared thermal imagery, in this adaptive region, maximize the placed in the middle location parameter showing according to calculated reference picture, thereby reference picture is set is arranged in the location parameter of infrared thermal imagery; For example, also can for example, according to the incidental parameter of reference picture (having embodied the location parameter in infrared thermal imagery), reference picture be set be arranged in the location parameter of infrared thermal imagery according to this parameter; Or, also can reference picture is set be arranged according to the configuration of thermal imagery device 100 (placed in the middle, original size) location parameter of infrared thermal imagery; Or, also can be according to the location parameter of user's input.
Operating portion 12: carry out various indication operations for user, or input the various operations such as set information, control part 11, according to the operation signal of operating portion 12, is carried out corresponding program.With reference to figure 2, operating portion 12 is described, provides that button that user operates records that key 1, focusing key 2, acknowledgement key 3, playback key 4, menu are strong 5, directionkeys 6 etc.; In addition, also can adopt touch-screen 7 or speech recognition component (not shown) etc. to realize relevant operation.
The variation of the display interface in shooting process is described with reference to figure 6, the control flow of the detecting pattern of thermal imagery device 100 is described referring to Fig. 7.This application scene thermal imagery device 100 as hand-held in user is taken the subject of transformer station.The control program of control part 11 based on storage in flash memory 3, and the various data that use in each several part control, controlled the overall action of thermal imagery device 100 and the control of execution various modes processing.After switching on power, control part 11 carries out the initialization of internal circuit, then, enter standby screening-mode, be that shoot part 1 is taken acquisition thermal-image data, shoot part 1 is taken the processing that the thermal-image data of acquisition stipulates by image processing part 7, be stored in interim storage part 2, on display part 10, show continuously infrared thermal imagery with dynamic image form, at this state, control part 11 is implemented it and is controlled, and whether persistent surveillance has been switched to the processing of other patterns or has carried out power-off operation according to scheduled operation, if had, enter corresponding processing controls.The control step of detecting pattern is as follows:
Steps A 01, determines reference picture;
At standby shooting state, display part 10 shows dynamic infrared thermal imagery, user can puzzle in specific shot body heat as the image space in the morphological feature of IR1 and the infrared thermal imagery at its place in the past, size, angle, for guaranteeing shooting quality standard, scheduled operation by operating portion 12 is selected detecting pattern, the table 3 of control part 11 based on storage in flash memory 3, the subject indication information of subject Information generation is presented to display part 10, when user is according to the subject of floor " subject 1 ", select " subject 1 " shown on display part 10 by operating portion 12, reference picture specifying part 11F is according to user's selection, just determine reference picture T1, from flash memory 3, read the composition data of reference picture T1, be sent to interim storage part 2, and position setting unit 11G arranges the location parameter (position and size) that reference picture T1 is positioned at infrared thermal imagery.For example, according to attached location parameter, reference picture T1 be set be arranged in the location parameter of infrared thermal imagery.In addition, self-adaptation viewing area that also can be according to the rules, or user's location parameter of specifying, determine that reference picture T1 is arranged in the location parameter of infrared thermal imagery.
In steps A 02, feature registration unit registration subject identifying information.Feature registration unit is according to user's selection " subject 1 ", just determined to be used for the subject identifying information of coupling, at this, supposes with reference to image T1 as the template image that calculates the degree of correlation.(in addition, also can from flash memory 3, read template data 301 and be used as calculating the subject identifying information of the degree of correlation).
Steps A 03, obtains thermal-image data frame, and the thermal-image data frame of shoot part 1 being taken to acquisition is sent to interim storage part 2, image processing part 7 carries out for example pseudo-color conversion of predetermined processing to obtained thermal-image data frame, obtain the view data of infrared thermal imagery, and, synthesis unit obtains determined composition data the view data of reference picture T1 according to the given size arranging, according to set assigned position, synthesize (overlapping) with the view data of the infrared thermal imagery generating, leave synthetic view data in interim storage part 2, then, composograph is presented at display part 10 by display control unit 9, as shown in Figure 6 (a), location between subject thermal imagery IR1 and contour images T1, the difference of size, user can take subject thermal imagery IR1 according to reference picture.As specific shot body heat picture do not detected in subsequent treatment, by constantly synthesizing with the thermal-image data frame newly obtaining, with this, constantly show dynamic composograph.
Then, in steps A 04, read the thermal-image data frame for example being obtained by the instant shooting of shoot part 1 in interim storage part 2, detection window setting unit, arranges detection window.For example, the upper left corner of the surveyed area G1 based on regulation, is first provided with detection window;
Steps A 05, carries out the processing of the relatedness computation between thermal-image data and the subject identifying information in detection window.
And, in steps A 06, the value of the degree of correlation that storage obtains.
In steps A 07, test section 8 judges while detection window being set in thermal-image data frame, whether has calculated the degree of correlation for all detection windows.If the region (being no in steps A 07) that residue is not also calculated the degree of correlation, gets back in steps A 04, detection window setting unit is in a predetermined direction by the position skew intended pixel number of detection window, this position is set to the next position of detection window, and repeats follow-up processing.
In addition, from thermal-image data frame, search is with like template class when frame part, for amplifying and dwindle and during by detection window after detection window J1 inclination predetermined angular, the Check processing that also carries out similar above-mentioned explanation.
If calculated the degree of correlation (being yes in steps A 07) for all detection windows of thermal-image data frame, the value of the maximal correlation degree detecting (or also by location parameter of corresponding detection window) is remained on to the regulation region of interim storage part 2 in steps A 08.
In steps A 09, compare with the correlative value of the degree of correlation;
If be less than this correlative value, represent specific shot body heat picture in the thermal-image data frame of current detection and the similarity degree of contour images T1, the correlative value obtaining before not being better than; Get back to steps A 03, repeat follow-up processing; At this, shooting distance, image space, angle between the position that user takes by change and optics and the specific shot body heat picture of adjustment thermal imagery device 100, be accompanied by user's adjustment operation, repeats follow-up processing.When the degree of correlation detecting in steps A 09 is greater than the correlative value of the degree of correlation, enter steps A 10;
Wherein, the correlative value of the degree of correlation can be that the correlative value of the pre-prepd initial degree of correlation is (for example, by the judgment value that judges whether to detect that whether specific shot body heat picture mates with subject identifying information, as the correlative value of the initial degree of correlation), when the value that detects the degree of correlation obtaining is greater than this judgment value, the degree of correlation of the specific shot body heat picture that detects of representative is better than prepared judgment value, this judgment value is replaced with to the correlative value that the value of current the detected degree of correlation obtains; As the correlative value of the subsequent detection degree of correlation, whether can obtain the specific shot body heat picture that the degree of correlation is higher so that follow-up.In the present embodiment, the correlative value of the thermal imagery device 100 initial degrees of correlation is 72%, this initial correlative value is the judgment value that judges whether to detect specific shot body heat picture, if the degree of correlation of the thermal-image data frame obtaining is less than this correlative value, represents and specific shot body heat picture in this thermal-image data frame, do not detected; Its effect is repeatedly to take also cannot obtain announcement information time as user, means whether taken wrong subject.So, in Fig. 6 (a), because the value of the detected degree of correlation is less than 72%, do not have show be used for notice information.And as shown in Fig. 6 (b), the degree of correlation of the thermal-image data frame of the maximal correlation degree detecting is 80%, notify follow-up.
In addition, the correlative value of the degree of correlation, also can not prepare in advance, at this moment, for example, when by the value of the degree of correlation of the thermal-image data frame detecting for the first time, the correlative value of the value of the degree of correlation obtaining as subsequent detection thermal-image data frame, when subsequent detection is when being greater than this correlative value, replace this correlative value.
At this, whether to be greater than correlative value as evaluating the foundation of the degree of correlation, be less than correlative value or approach correlative value (pre-prepd judgment value) as the situation of evaluating the degree of correlation but also have.And correlative value can be the value of the degree of correlation, it can be also the value of the degree of correlation value etc. through converting and obtaining.
Steps A 10, the correlative value renewal 11C of portion, by according to the detected value with maximal correlation degree, upgrades the correlative value of the degree of correlation, and the correlative value after renewal is as the correlative value of the comparison degree of correlation of follow-up thermal-image data frame.
Steps A 11, selection portion 11B, by customizing messages such as thermal-image data the frames corresponding detected value with maximal correlation degree, remains on the regulation region of interim storage part 2, the customizing messages (if there is) before replacing it.In addition, also can keep the relevant customizing messages of multiple thermal-image data frames of specified quantity, for example, keep the customizing messages such as 3 frame thermal-image data frames and the value of the degree of correlation thereof that the degree of correlation is the highest.
Steps A 12, notifies, and the relevant customizing messages of thermal-image data frame that detects the degree of correlation maximum obtaining is notified.
For example, the image that this thermal-image data frame is obtained, shows jointly with dynamic infrared thermal imagery.And the customizing messages keeping, before not receiving customizing messages that selection portion 11B reselects or user's indication, will be maintained in interim storage part 2 always.
Being not limited to and showing infrared thermal imagery 601, can be also other mode, and the value that for example directly will calculate the degree of correlation shows, as the difference of direct display pixel value and numerical value etc.In addition, also can will show that Dynamic IR thermal imagery switches to the freeze frame that shows this thermal-image data frame; Preferred mode, also can notify the region of the detected detection window with maximal correlation degree (or the location parameter of subject etc.).The mark of the position of the subject thermal imagery with maximal correlation degree that for example signal detects in the infrared thermal imagery freezing etc.Maybe will show that Dynamic IR thermal imagery switches to the freeze frame that shows this thermal-image data frame, then, response user's indication, then switch the show state of state infrared thermal imagery of reversing, or this thermal-image data frame image and the common state showing of dynamic infrared thermal imagery that obtain.In addition, also can not show the infrared thermal imagery that this thermal-image data frame obtains, and display reminding information; Or with vibration, pilot lamp flicker etc., the mode that various users can discover.And, in the time that selection portion 11B is configured to indication maintenance multiframe thermal-image data frame, can show the infrared thermal imagery that multiple kept thermal-image data frames obtain simultaneously, for example, also carry out sequencing display according to the height of the degree of correlation.
Note, in the time not contrasting with the correlative value (representing the judgment value whether specific shot body heat picture mates with subject identifying information) that judges whether to have specific shot body heat picture, the information of the shown degree of correlation might not represent whether specific shot body heat picture detected.
And, be not limited to and notify selection portion selected customizing messages, the event that also can upgrade correlative value or also further notice correlative value.
Steps A 13, judges whether to exit, as does not exit, and gets back to steps A 03, repeats follow-up processing.At this moment, due in steps A 11, the correlative value of the degree of correlation is upgraded, therefore, the thermal-image data frame obtaining in follow-up shooting, by with upgrade after the correlative value of the degree of correlation compare, and, in the time being greater than the correlative value of the degree of correlation, kept customizing messages is upgraded, and, in steps A 12, notify.
As shown in Fig. 6 (b), in shooting, first the maximal correlation degree detecting is 80%(according to the ratio sum of the overlapping area information obtaining that converts), the correlative value of the degree of correlation using the value of this degree of correlation as follow-up comparison, and show with Dynamic IR thermal imagery the infrared thermal imagery 601 that this thermal-image data frame obtains simultaneously.In the time that subsequent detection is greater than 80% to the value of maximal correlation degree, as shown in Fig. 6 (c), the value of the degree of correlation is 95%, replace the correlative value 80% of the degree of correlation, as the correlative value (95%) of the new degree of correlation, by that analogy, in the time that the value of the detected degree of correlation is 95%, as shown in Fig. 6 (c), if user is satisfied, can stop the aiming of subject to take, because this thermal-image data frame remains in interim storage part 2 storage mediums such as grade, can conveniently carry out follow-up analysis, storage etc. and process or operate.At this moment, record key if user presses, the processing that the thermal-image data frame of infrared thermal imagery 603 correspondences stipulated (as compression etc.) is recorded to storage card 8.And, even if the not mode of display reminding information or infrared thermal imagery, for example mode of pilot lamp flicker, because this thermal-image data frame remains in interim storage part 2 storage mediums such as grade, equally can be in the time of the pressing acknowledgement key or record key of user, show, the processing such as record.
And, information that also can update notifications correlative value, and do not notify the information of thermal-image data frame.
And, the in the situation that of some application, to specific shot body heat picture whether being detected, be not limited to the comparison between the value of the degree of correlation and the correlative value of the degree of correlation, also deformable is for example according to detecting evaluation of estimate that the provisioning information that obtains and/or provisioning information obtain and the comparative result of predetermined correlative value, is used as whether detecting the foundation of specific shot body heat picture.
As mentioned above, in the present embodiment, show that reference picture assists shooting, and in the time the degree of correlation being detected higher than the thermal-image data frame of fiducial value, just select this thermal-image data frame or also notified, and follow-up whenever detect higher than the degree of correlation before correlative value time, can constantly update correlative value, and the information of notifying, can reach and significantly reduce the operation easier that vision is aimed at, significantly reduce the physical strength of taking, improve the beneficial effect of the quality of the final thermal-image data frame obtaining.Common user easily grasps this shooting technical ability.Certainly, arbitrary product of enforcement embodiments of the present invention might not need to reach above-described all advantages simultaneously.
And, in the field of infrared detection, owing to considering the difference at the position of specific shot body heat picture in infrared thermal imagery, size, angle of inclination etc., corresponding different shooting quality, even if the degree of correlation is high, if above-mentioned parameter is undesirable, the quality of the thermal-image data frame obtaining is not necessarily high; Therefore, consider the factor such as value of the position of specific shot body heat image position in thermal-image data frame, size, angle of inclination, the degree of correlation, for example according to above-mentioned because usually obtaining evaluation of estimate (can be one or more), compare with the correlative value of regulation, as carrying out the selection of regulation thermal-image data frame and the factor of notifying, point out user to note the quality of taking, or select the thermal-image data frame of best shooting quality to carry out follow-up processing.
Embodiment 2, is with the difference of embodiment 1, and the thermal-image data frame that the test section 8 of described thermal imagery device 100 obtains continuously based on acquisition unit (shoot part 1) detects the provisioning information relevant with specific shot body heat picture in thermal-image data frame; Control part 11 has supplementary acquisition unit (not shown), for obtaining supplementary; Comparing section 11A, for test section being detected to the provisioning information obtaining, supplementary that supplementary acquisition unit is obtained, test section detect evaluation of estimate that the provisioning information that obtains obtains, supplementary that supplementary acquisition unit is obtained and the evaluation of estimate, the test section that obtain detect the supplementary that the provisioning information that obtains and supplementary acquisition unit obtain and the evaluation of estimate obtaining one or more compares with corresponding one or more correlative values; Selection portion 11B, the comparative result of the 11A of portion based on the comparison, selects the customizing messages relevant with the thermal-image data frame of regulation, when there being multinomial comparison, according to different comparative results, the customizing messages of notifying may be a frame or the relevant customizing messages of multiframe thermal-image data frame; Notification unit 11D, the relevant customizing messages of thermal-image data frame selected based on selection portion 11B and regulation, notifies.The correlative value renewal 11C of portion, for the renewal of correlative value.
Wherein, described provisioning information, at least comprises the information of a kind of or combination in any in the value of position, size, angle of inclination, the degree of correlation of specific shot body heat picture.
In the field of infrared detection, owing to considering the difference at the position of specific shot body heat picture in infrared thermal imagery, size, angle of inclination etc., corresponding different shooting quality, even if the degree of correlation is high, if above-mentioned parameter is undesirable, the quality of the thermal-image data frame obtaining is not necessarily high; Therefore, consider the factors such as the position of specific shot body heat image position in thermal-image data frame, size, angle of inclination, as the factor that generates notice, point out user to note the quality of taking, or select the thermal-image data frame of best shooting quality to carry out follow-up processing.
Wherein, described supplementary, at least comprise the information of a kind of or combination in any in assay value, environment temperature, contextual factor, wind speed, humidity, distance, and other supplementarys of being obtained by thermal imagery device 100 (comprise by user and arranging), comprise other various to the relevant information of the selected regulation thermal-image data of selection portion 11B frame and/or the influential factor of information that notification unit 11D is notified all in its scope.
In the application of infrared detection, according to the difference of above-mentioned supplementary, the quality of the thermal-image data frame obtaining and significance level difference, should have different conditions to deal with the processing such as the comparison of the thermal-image data frame of regulation, selection, notice; For example, for example, in the time thering is the assay value of correlative value (threshold values of defect) that is greater than regulation in the specific shot body heat picture obtaining, represent that subject has defect, so, should cause user's attention, at this moment, in the situation that the degree of correlation approaches, also preferably select the relevant customizing messages of thermal-image data frame that also notification analysis value exceeds standard, user's attention will be caused immediately, significant to infrared detection; For example consider environment temperature, background, wind speed, the contextual factor (otherness of for example background and subject thermal imagery, the thermal field distribution of background etc.) etc. influence factor, in the situation that the degree of correlation approaches, these influence factors may cause the value of different thermal imagery quality and subsequent analysis to reduce, and should select and notify other influences factor to disturb little thermal-image data frame.
Wherein, supplementary acquisition unit, for example can obtain above-mentioned supplementary according to thermal imagery device 100 or with the parts (not shown) of the corresponding function being connected in thermal imagery device 100, for example, (assay value is not limited to temperature value to obtain assay value by analysis component, for example, also can be AD value, color value in pseudo-color thermal imagery, the ratio of specific picture numerical value, or also by these numerical value according to the rules formula calculate the value etc. obtaining, the assay value that analysis component is obtained can be for the pixel in whole pixels or particular analysis region in thermal-image data frame), obtain environment temperature by temperature sensor, obtain humidity by hygrometer, obtain the distance of thermal imagery device 100 and subject etc. by stadimeter.Also can obtain according to above-mentioned supplementary pre-stored in storage medium, for example, the historical data of supplementary; Or in conjunction with the historical data of supplementary pre-stored in the supplementary of obtaining when pre-test and storage medium to recently obtaining supplementary.
And, can obtain comprehensive evaluation of estimate by provisioning information and/or supplementary; For example, the different coefficient that can adopt customizing messages correspondence in detected provisioning information, and obtain evaluation of estimate by other the provisioning information in detected provisioning information in conjunction with this coefficient; For example, can adopt the shared weight of different information, obtain evaluation of estimate by weighting.Can obtain final evaluation of estimate by various account form.For example, as shown in Figure 9, the detection window that the infrared thermal imagery 901 of supposing Fig. 9 (c) is 0.94 according to window coefficient obtains, and the detection window that infrared thermal imagery 902 is 0.8 according to window coefficient obtains, value × window coefficient of evaluation of estimate=degree of correlation, therefore, even if the degree of correlation of infrared thermal imagery 901 is less than the degree of correlation of infrared thermal imagery 902, but evaluation of estimate is high on the contrary.
And, also can, by described provisioning information and described supplementary, obtain comprehensive evaluation of estimate.For example, acquisition combines the evaluation of estimate that the value of position, size, angle of inclination, assay value, the degree of correlation of specific shot body heat picture obtains, for example obtain comprehensive evaluation value according to following formula, value × degree of correlation weighting coefficient of weighting coefficient+size × size weighting coefficient+angle of inclination × angle of inclination, comprehensive evaluation value=position × position weighting coefficient+assay value × assay value weighting coefficient+degree of correlation; Or another kind of preferred mode, obtains evaluation of estimate according to detected provisioning information and the supplementary of obtaining and the table of comparisons of comprehensive evaluation value.
And, also can be according to described provisioning information and described supplementary, wherein part obtains evaluation of estimate, then, according to the provisioning information and/or the supplementary that obtain evaluation of estimate of having neither part nor lot in wherein, together with the evaluation of estimate obtaining, the object of the comparison of the correlative value of portion and regulation as a comparison.
Wherein, the correlative value renewal 11C of portion, according to the comparative result of comparing section 11A, upgrades correlative value; And, in the time having multinomial correlative value, at least one in corresponding correlative value is upgraded; Wherein, when multinomial correlative value update all, after renewal, described comparing section 11A, for the provisioning information that test section 8 subsequent detection are obtained, and/or, the supplementary of obtaining based on supplementary acquisition unit, and/or, by described provisioning information and/or described supplementary and the evaluation of estimate obtaining compare with the correlative value of multinomial renewal; Wherein, when part in multinomial correlative value is upgraded, after renewal, with the correlative value of the renewal item in multinomial correlative value and a correlative value of not upgrading compare.Preferably, the optimum provisioning information relatively obtaining according to comparing section or optimum supplementary or optimum according to one that detects in the evaluation of estimate that the provisioning information that obtains and/or supplementary obtain, upgrade corresponding at least one correlative value.
Wherein, when test section 8 is configured to detect multiple provisioning informations of specific shot body heat picture, and comparing section 11A, when the provisioning information that 8 detections obtain to test section and/or the multinomial correlative value of the evaluation of estimate obtaining based on detecting the provisioning information of acquisition and regulation compare, result based on the comparison, selection portion 11B may select the relevant customizing messages of multiple thermal-image data frames, and at this moment, notification unit 11D can be to one of them or multiple notice.Preferably, described selection portion, the comparative result of portion based on the comparison, the relevant customizing messages of thermal-image data frame that the value of the selection degree of correlation and/or provisioning information and/or supplementary and/or evaluation of estimate (evaluation of estimate that provisioning information and/or supplementary obtain) are better than the correlative value of regulation keeps.Described notification unit, selected based on selection portion and the keep relevant customizing messages of the thermal-image data frame with regulation, the value of the selection degree of correlation and/or provisioning information and/or supplementary and/or evaluation of estimate (evaluation of estimate that provisioning information and/or supplementary obtain) are better than the relevant customizing messages of thermal-image data frame of the correlative value of regulation and notify.
The control flow of the detecting pattern of the thermal imagery device 100 of embodiment 2 is described referring to Fig. 8, and in the following description, having configured three correlative values is example.The provisioning information (value of the degree of correlation) relevant with specific shot body heat picture in the thermal-image data frame that test section 8 is detected, based on detecting the supplementary (assay value) that the provisioning information that obtains and supplementary acquisition unit obtain, the evaluation of estimate obtaining compares with first, second, third correlative value.
The first correlative value is prepared (being the first correlative value of the degree of correlation in the present embodiment) in advance, the correlative value (representing the judgment value whether specific shot body heat picture mates with subject identifying information) that is used for judging whether to have specific shot body heat picture, the first correlative value is not upgraded.
The second correlative value (being the second correlative value of the degree of correlation in the present embodiment), for being greater than the correlative value of the degree of correlation of the first correlative value, its value according to the degree of correlation of the thermal-image data frame detecting obtains, in the time that follow-up thermal-image data frame detects the value of the higher degree of correlation, the second correlative value will be updated to higher value thereupon.
The 3rd correlative value, value, assay value etc. with position, size, angle of inclination, the degree of correlation obtain comprehensive evaluation value, as for example, comparing with corresponding (pre-prepd) the 3rd correlative value, in the time that follow-up thermal-image data frame detects the comprehensive evaluation value of higher (more excellent), the 3rd correlative value will be updated to higher value thereupon.
Finally, selection portion 11B is by the relevant customizing messages of thermal-image data frame of selecting to be better than the second correlative value and/or to be better than the 3rd correlative value; Be convenient to the processing such as follow-up notice, analysis, diagnosis, record.
Steps A 01-steps A 03, is analogous to the steps A 01-A03 of embodiment 1, has omitted explanation;
Step B03, is analogous to the steps A 04-A08 of embodiment 1, detects and obtains the degree of correlation, has omitted explanation;
Step B04, whether the value of the degree of correlation of the thermal-image data frame that judgement detects, be greater than the first correlative value, as no, represents specific specific shot body heat picture not detected, gets back to steps A 03, repeats follow-up processing.
When the degree of correlation detecting at step B04 is greater than the first correlative value, enter step B05.
Step B05, supplementary acquisition unit is greater than the thermal-image data in thermal-image data frame and/or this thermal-image data frame detection window of the first correlative value to the degree of correlation, obtain for example assay value relevant with specific shot body heat picture of supplementary etc., for example control analysis parts are analyzed acquisition assay value.In addition, for example, in the time that test section 8 is configured to calculate the degree of correlation by detection pixel ratio, be not limited to decide according to the location parameter of detection window the location parameter of detected specific shot body heat picture, at this moment, also can, according to the profile that further extracts specific shot body in the detection window detecting, obtain the provisioning informations relevant with specific shot body heat picture such as more accurate position, size, angle of inclination.
Step B06, obtain evaluation of estimate, acquisition combines position, size, the angle of inclination of specific shot body heat picture, the value of the degree of correlation, the evaluation of estimate that assay value obtains, for example obtain comprehensive evaluation value according to following formula, value × degree of correlation weighting coefficient+assay value × assay value weighting coefficient of weighting coefficient+size × size weighting coefficient+angle of inclination × angle of inclination, comprehensive evaluation value=position × position weighting coefficient+degree of correlation; Or another kind of preferred mode, obtains evaluation of estimate according to detecting the provisioning information of acquisition and the table of comparisons of the supplementary of obtaining and comprehensive evaluation value.
Step B07, compares with the 3rd correlative value, as while being less than the 3rd correlative value, at step B08, the value and the second correlative value that detect the degree of correlation obtaining is compared; As no, jump to step B19, before representative, detect that the degree of correlation is than the thermal-image data frame of the thermal-image data vertical frame dimension of current detection.In this way, at step B09-B10, the correlative value renewal 11C of portion, by according to the value of detected maximal correlation degree, upgrades the second correlative value.And, selection portion 11B is by customizing messages relevant this thermal-image data frame, remain on the regulation region of interim storage part 2, or also replace it front customizing messages (if there is the previous relevant customizing messages of thermal-image data frame, and the degree of correlation of thermal-image data frame is before less than the thermal-image data frame of current detection, and when evaluation of estimate is not maximum in kept thermal-image data frame, just replace), and at step B11, the relevant customizing messages of thermal-image data frame that the degree of correlation is greater than to the second correlative value is notified.
If step B07, as comprehensive evaluation value is greater than the 3rd correlative value, at step B12, compares the value of the degree of correlation and the second correlative value;
If be greater than the second correlative value, at B13-B14, the correlative value renewal 11C of portion is by according to the value of the detected maximal correlation degree of this thermal-image data frame, and maximum comprehensive evaluation value upgrades the second correlative value, the 3rd correlative value.And, selection portion 11B is by the customizing messages relevant with this thermal-image data frame, remain on the regulation region of interim storage part 2, or also replace it before customizing messages (if there is), and at step B11, the degree of correlation is greater than to the relevant customizing messages of thermal-image data frame that the second correlative value and comprehensive evaluation value be greater than the 3rd correlative value and notifies.
If be less than the second correlative value, at B16-B17, the correlative value renewal 11C of portion, by according to the comprehensive evaluation value of detected this thermal-image data frame, upgrades the 3rd correlative value.And, selection portion 11B has by detected a relevant customizing messages of thermal-image data frame that maximum comprehensive evaluation value is corresponding, remain on the regulation region of interim storage part 2, customizing messages (if the relevant customizing messages of thermal-image data frame before having before replacing it, and the evaluation of estimate of thermal-image data frame is before less than the thermal-image data frame of current detection, and when the degree of correlation is not maximum in kept thermal-image data frame, just replace), and at step B18, the relevant customizing messages of thermal-image data frame that comprehensive evaluation value is greater than to the 3rd correlative value is notified.
Step B19, judges whether to exit detecting pattern, as exits, and finishes, as does not exit, and gets back to step B02, repeats above-mentioned processing.Like this, the thermal-image data frame that continuous shooting is obtained, according to detected provisioning information, selects the relevant customizing messages of thermal-image data frame that is better than the second correlative value and/or is better than the 3rd correlative value and notify; Be convenient to the processing such as follow-up notice, analysis, diagnosis, record.Wherein, whether the degree of correlation of the thermal-image data frame of detection is greater than to the condition of the first correlative value as further detection provisioning information, can further avoids the beneficial effect of taking error location, pointing out effective customizing messages.Here so-called being better than, according to the difference of correlative value, may there is the situation that is less than or greater than correlative value.
