In steps A 08, 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 08) that residue is not also calculated the degree of correlation, gets back in steps A 05, 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 08) for all detection windows that will arrange in thermal-image data frame, the value of the maximal correlation degree the detecting location parameter of corresponding detection window (or also have) is remained on to the regulation region of interim storage part 2 in steps A 09.

In steps A 10, whether calculate the degree of correlation for all thermal-image data frames.As no, get back to steps A 04, repeat follow-up processing.In this way,, in steps A 11, by the thermal-image data frame of detected multiframe part, pick out the maximum degree of correlation, compare with the correlative value of the degree of correlation;

In steps A 11, compare with the correlative value of the degree of correlation;

Wherein, the correlative value of the degree of correlation can be the correlative value (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) of the pre-prepd initial degree of correlation.

If be less than this correlative value, represent not detect the thermal-image data frame that is better than correlative value with the degree of correlation; Enter steps A 13, also can in display part 10, show that user notified in the printed words of " specific shot body heat picture not detected ", or be shown as Dynamic IR thermal imagery, as shown in Figure 6 (a); Then, as do not exit, get back to steps A 01, at this, shooting distance, image space, angle between optics and the subject thermal imagery of the position that user takes by change and adjustment thermal imagery device 100, in the time again sending detection indication, repeat follow-up processing.

When the value that detects the degree of correlation obtaining is greater than this judgment value, enter steps A 12, select the highest relevant customizing messages of thermal-image data frame (also can select some frames that the degree of correlation is high) of the degree of correlation.

In addition, the correlative value of the degree of correlation, also can not prepare in advance, and at this moment, for example, selection portion 11B, according to the comparative result of comparing section 11A, selects thermal-image data frame or some frames of degree of correlation maximum in interim storage part 2.Note, when not with when judging whether that the correlative value consistent with subject identifying information contrasts, the thermal-image data frame of selected degree of correlation maximum might not represent whether have specific shot body heat picture (coupling).

And in steps A 13, recording unit 11C, for the relevant customizing messages of thermal-image data frame of selecting based on selection portion 11B, the control of recording.

A kind of embodiment, recording unit 11C controls, and carries out selected thermal-image data frame is carried out to the control of recording processing.Make the thermal-image data frame of selection portion 11B selection and detect the provisioning information (value of position, size, angle of inclination, the degree of correlation) obtaining, or the subject information of selecting before being also included in, Heat of Formation arrives storage card 8 as file record, finishes this processing.

Particularly, make image processing part 2 implement the compression processing of regulation to this thermal-image data frame, or the processing that this thermal-image data frame is implemented to regulation is compressed processing after as processing such as correction, interpolation, thermal-image data frame after described provisioning information (or also comprising subject information) and compression is associated, Heat of Formation to storage card 8, finishes this processing as file record.See the one enforcement schematic diagram of the thermal imagery file structure in Fig. 7; Wherein, regulation recorded information 7001: the provisioning information that subject information " subject 1 ", detection obtain.Thermal-image data 7002 is the thermal-image data frame after compressing; The time of other additional informations 7003 as shooting etc.

In addition, the storage medium of record is not limited to storage card 6, flash memory 3 etc., can be also by the network destination of communication I/F4 communication.

In addition, associated record processing also refers to regulation recorded information to be recorded in message file or the index file of thermal imagery file association medium, and recording unit 11C can generate this message file or index file.

As shown in Fig. 6 (a), owing to not detecting that the degree of correlation is greater than the thermal-image data frame of correlative value, therefore, does not carry out record.

As shown in Fig. 6 (b), detect that the degree of correlation is greater than the thermal-image data frame of correlative value, selection portion 11B is by the value of for example degree of correlation of the customizing messages relevant with this thermal-image data frame, this thermal-image data frame, and then, this thermal-image data frame is carried out automatic record by recording unit 11C.

Steps A 14, judges whether to exit, as does not exit, and gets back to steps A 01, repeats follow-up processing.

As mentioned above, in the present embodiment, owing to having set the surveyed area of regulation, can be convenient to the scope that user understands shooting, when receiving the indication of detection, detect and in interim storage part 2, store to obtain the highest frame of the degree of correlation in thermal imagery signal frame, the line item processing of going forward side by side; Can lower the manipulation strength that vision matching is aimed at, common user easily grasps this shooting technical ability, simple to operate, and can reduce the arithmetic speed burden of processor, the beneficial effect of the cost of reduction thermal imagery device 100 etc., and be applicable to the shooting to fast-moving target.

Embodiment 3

Embodiment 3, is with the difference of embodiment 1,2, thermal imagery device 100(infrared record control device 100) there is the correlative value renewal 11E of portion, for correlative value is upgraded.Figure 11 be represent the infrared record control device 100 of embodiments of the invention 3 example thermal imagery device 100 summary form block diagram.Give identical numbering to the formation identical with embodiment 1, omitted explanation.

Control part 11 has the correlative value renewal 11E 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.

For the correlative value of upgrading, 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.

For the correlative value of upgrading, can be also to obtain 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.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.

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.

Notification unit 11D, 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.

And, in the present embodiment, described selection portion 11B, for the relevant customizing messages of multiple thermal-image data frames keeping before correlative value is upgraded, after correlative value is upgraded, according to the comparative result of comparing section 11A, at least replace one of them relevant customizing messages of selected thermal-image data frame before.But be not limited to this, also can keep correlative value to upgrade the customizing messages of front and back.And, notification unit 11D, the relevant customizing messages of thermal-image data frame that notice selection portion 11B newly selects.

The control flow of the detecting pattern of thermal imagery device 100 is described referring to Figure 13, the variation of the display interface in shooting process is described with reference to Figure 12.

Step D01-step D02, is analogous to the steps A 01-A02 of embodiment 1, has omitted explanation;

Step D03, is analogous to the steps A 03-A10 of embodiment 1, detects the degree of correlation of the thermal-image data frame of multiframe part, has omitted explanation;

At step D04, compare with the correlative value of the degree of correlation; Being about to wherein maximal correlation degree and correlative value compares;

If be less than this correlative value, represent not detect the maximal correlation degree (as the correlative value after upgrading) of the thermal-image data frame that is better than previous correlative value with the degree of correlation or obtained before; Get back to step D01, show the printed words that better thermal-image data frame do not detected; Then, shooting distance, image space, angle between the position that user takes by change and optics and the subject thermal imagery of adjustment thermal imagery device 100, when user sends indication again, repeat follow-up processing.

Wherein, preferred mode, the correlative value that an initial degree of correlation can be set (for example will judge whether to have the correlative value of specific shot body heat picture, 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.

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.

When the degree of correlation detecting at step D04 is greater than the correlative value of the degree of correlation, enter step D05; Wherein, if do not stored before the correlative value of the degree of correlation, can be using the value of the degree of correlation obtaining for the first time as the correlative value of the degree of correlation.

Step D05, the correlative value renewal 11E 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.

Step D06, 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.Then, at step D07, can notify, judge whether record indication at D08, if had, carry out recording processing at D09.And, be not limited to notify the selected customizing messages of selection portion 11B, the correlative value after the event that also can upgrade correlative value or also further update notifications.

Step D10, judges whether to exit, as does not exit, and gets back to step D01, repeats follow-up processing.At this moment, when user sends the indication of detection again, because the correlative value to the degree of correlation is upgraded, therefore, follow-up read and detect thermal-image data frame from thermal imagery storage part time, by with upgrade after the correlative value of the degree of correlation compare, and, when subsequent detection to the value of the degree of correlation while being greater than the correlative value of the degree of correlation, the correlative value of the degree of correlation will be upgraded again, and selection portion 11B is also upgraded kept customizing messages, and, at step D07, notify (the relevant information of thermal-image data frame of notice degree of correlation maximum).

In embodiment 1,2, due to only with regulation fiducial value (for example, represent the correlative value whether subject thermal imagery mates with subject identifying information) compare, and do not upgrade fiducial value, therefore, in follow-up shooting, poor before the mass ratio of thermal-image data frame likely obtaining.

And in embodiment 3, as the infrared thermal imagery 1201 as shown in Figure 12 (a) first detected, because the correlative value to the degree of correlation (supposing that initial correlative value is 72%) has carried out upgrading (being updated to 85%), therefore, when the degree of correlation of detected thermal-image data frame in interim storage part 2 is lower than 85% time, to can not notify, or the printed words of notice " not photographing better infrared thermal imagery ".Then, as the infrared thermal imagery 1202(95% photographing as shown in Fig. 6 (b)) time, just notify; And selection portion 11B selects the relevant customizing messages of thermal-image data frame of maximal correlation degree to keep all the time, user just can adjust thermal imagery device 100 relievedly like this, to pursue the thermal imagery of taking optimum efficiency.

As mentioned above, in the present embodiment, 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 and notified, and follow-up whenever detect higher than the degree of correlation before correlative value time, can constantly update correlative value, and keep follow-up the selected relevant customizing messages of thermal-image data frame, or also replace the customizing messages of original maintenance; Obviously,, according to the selected information of selection portion 11B, notify, can improve the convenience that records thermal-image data frame, and can reach the operation easier that significantly reduces vision matching aligning, and significantly reduce the physical strength of taking, improve the beneficial effect of the quality of the thermal-image data frame of final acquisition.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.

It may be noted that in

embodiment

1,2,3, to specific shot body heat picture whether being detected, with between the value of the degree of correlation and the correlative value of the degree of correlation more as an example, but above are only example, be not limited thereto.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, recording, 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 recording processing.

Obtain comprehensive evaluation of estimate by provisioning information; 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, as shown in figure 12, the detection window that the infrared thermal imagery 1201 of supposing Figure 12 (a) is 1 according to window coefficient obtains, and the detection window that infrared thermal imagery 1202 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 1301 is less than the degree of correlation of infrared thermal imagery 1302, but evaluation of estimate is high on the contrary.

Also can adopt the shared weight of different information, obtain evaluation of estimate by weighting.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+degree of correlation;

Or obtain evaluation of estimate according to the table of comparisons of detected provisioning information and comprehensive evaluation value.Can obtain final evaluation of estimate by various account form.And, also can be according to described provisioning information, wherein part obtains evaluation of estimate, then, and according to the provisioning information that obtains evaluation of estimate that has neither part nor lot in wherein, together with the evaluation of estimate obtaining, the object of the comparison of the correlative value of the 11A of portion and regulation as a comparison.

Thus, can be by

embodiment

1,2,3 are for example deformed into according to the comparative result of correlative value that detects evaluation of estimate that the provisioning information that obtains and/or provisioning information obtain and regulation, are used as the foundation that whether detects that specific shot body heat picture or selection, record etc. are processed.

Embodiment 4

With embodiment 1,2,3 difference is, thermal imagery device 100(infrared record control device 100) multiframe thermal-image data frame based in interim storage part 2, indication according to the rules, detects the provisioning information relevant with specific shot body heat picture in the multiframe thermal-image data frame of storing in interim storage part 2; 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.Control part 11 has supplementary acquisition unit (not shown), for obtaining supplementary; Comparing section 11A, the supplementary that the evaluation of estimate obtaining for test section being detected to the provisioning information obtaining, supplementary that supplementary acquisition unit is obtained, evaluation of estimate that provisioning information that test section 8 detects acquisition obtains, supplementary that supplementary acquisition unit is obtained, the provisioning information that test section 8 detects acquisition and supplementary acquisition unit are obtained and the evaluation of estimate that obtains 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, selected customizing messages 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 11E of portion, for the renewal of correlative value.

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.Like this, the quality of the thermal-image data frame of user record is than embodiment 1,2, higher in 3.

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 12, the detection window that the infrared thermal imagery 1201 of supposing Figure 12 (a) is 1 according to window coefficient obtains, and the detection window that infrared thermal imagery 1202 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 1301 is less than the degree of correlation of infrared thermal imagery 1302, 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 the 11A of portion and regulation as a comparison.

Wherein, the correlative value renewal 11E 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 11A 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 11B, the comparative result of the 11A 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 11D, selected based on selection portion 11B 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 4 is described referring to Figure 14,15, and in this example, 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 follow-up processing such as notice, record.

Step C01-step C02, is analogous to the steps A 01-A02 of embodiment 1, has omitted explanation;

Step C03, is analogous to the steps A 03-A10 of embodiment 1, detects the degree of correlation of the thermal-image data frame that obtains multiframe part, has omitted explanation;

Step C04, 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 step C01, for example, also show the printed words of the thermal imagery that coupling do not detected.Repeat follow-up processing.

When the degree of correlation detecting at step C04 is greater than the first correlative value, enter step C05.

Step C05, 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 C06, obtain evaluation of estimate, 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 detecting the provisioning information of acquisition and the table of comparisons of the supplementary of obtaining and comprehensive evaluation value.

Step C07, do are the maximal correlation degree in the thermal-image data frame that judgement detects and the thermal-image data frame of maximum evaluation of estimate same frames?

(step C07: be), enters step C08 in this way, and evaluation of estimate and the 3rd correlative value are compared.

As while being less than the 3rd correlative value (step C08: no), at step C09, the value and the second correlative value that detect the degree of correlation obtaining are compared; As no, jump to step C32, for example representative before the degree of correlation detected, than the thermal-image data frame of the thermal-image data vertical frame dimension of current detection.In this way, at step C10-C11, the correlative value renewal 11E 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, customizing messages (if the relevant customizing messages of thermal-image data frame before having before replacing it, 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 C12, the relevant customizing messages of thermal-image data frame that the degree of correlation is greater than to the second correlative value is notified.

As comprehensive evaluation value is greater than the 3rd correlative value (step C08: be), at step C13, the value of the degree of correlation and the second correlative value are compared;

If be greater than the second correlative value (step C13: be), at C14-C15, the correlative value renewal 11E 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, customizing messages (if there is) before replacing it, and at step C16, 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 (step C13: no), at C17-C18, the correlative value renewal 11E 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 C19, the relevant customizing messages of thermal-image data frame that comprehensive evaluation value is greater than to the 3rd correlative value is notified.

As step, C07(is no), represent in detected thermal-image data frame, the thermal-image data frame of degree of correlation maximum and the thermal-image data frame of evaluation of estimate maximum are different two frames (also may have multiframe), enter step C20, the evaluation of estimate of the thermal-image data frame of maximum evaluation of estimate and the 3rd correlative value are compared, see Figure 12.

As while being less than the 3rd correlative value (step C20: no), at step C21, value and second correlative value of the degree of correlation that detects the thermal-image data frame that obtains maximal correlation degree are compared; As no, jump to step B32, before representative, detect that the degree of correlation, evaluation of estimate are than the thermal-image data frame of the thermal-image data vertical frame dimension of current detection, display part will not show, or show the printed words that better thermal-image data frame do not detected.In this way, at step C22-C23, the correlative value renewal 11E 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, customizing messages (if the relevant customizing messages of thermal-image data frame before having before replacing it, 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 C24, the relevant customizing messages of thermal-image data frame that the degree of correlation is greater than to the second correlative value is notified.

As comprehensive evaluation value is greater than the 3rd correlative value (step C20: be), at step C25, the value of the degree of correlation and the second correlative value are compared; If be greater than the second correlative value (step C25: be), at C26-C27, the correlative value renewal 11E 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, customizing messages (if there is) before replacing it, and at step C28, thermal-image data frame, the comprehensive evaluation value that the degree of correlation is greater than to the second correlative value is greater than the relevant customizing messages of thermal-image data frame of the 3rd correlative value and notifies (for example two frames show) simultaneously.

If be less than the second correlative value (step C25: no), at C29-C30, the correlative value renewal 11E 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 C31, the relevant customizing messages of thermal-image data frame that comprehensive evaluation value is greater than to the 3rd correlative value is notified.

Step C32, carries out recording processing.The roughly the same D08-D09 in Figure 13; Omit explanation.

Step C33, judges whether to exit detecting pattern, as exits, and finishes, as does not exit, and gets back to step C01, repeats above-mentioned processing.Like this, when the thermal-image data frame that continuous shooting is obtained circulation are stored in interim storage part 2, when response detects indication, by according to detected provisioning information, 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 is selected and notified; Be convenient to the processing such as follow-up notice, analysis, diagnosis, record, maintenance.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.

The variation of the display interface in shooting process is described with reference to Figure 16.

As shown in Figure 16 (a), in the time not detecting that the degree of correlation is greater than the thermal-image data frame of the first correlative value (degree of correlation number percent that supposition the first correlative value converts is 72%), show dynamic infrared thermal imagery.

Response detects indication for the first time, as shown in Figure 16 (b), in the time detecting that the degree of correlation is greater than the thermal-image data frame of the first correlative value for the first time, show the announcement information that dynamic infrared thermal imagery is relevant with detected thermal-image data frame, the customizing messages of this thermal-image data frame of this announcement information based on the indicated storage of selection portion 11B for example this thermal-image data frame, the value of the degree of correlation, evaluation of estimate generate; Announcement information comprises the infrared thermal imagery 1601 that this thermal-image data frame generates, the degree of correlation number percent 88% that the value of the degree of correlation converts, the evaluation of estimate number percent 75% that evaluation of estimate converts.And it is that for example to upgrade (or generation) be 75% to 88%, the three correlative value that the correlative value renewal 11E of portion for example upgrades the second correlative value (or generate); And, not detecting when being greater than the second correlative value and/or being greater than the thermal-image data frame of the 3rd correlative value when follow-up, display part 10 will keep showing the state of infrared thermal imagery 1601 announcement informations such as grade and Dynamic IR thermal imagery; And due to the announcement information that infrared thermal imagery 1601 generates for the current customizing messages newly obtaining, the frame of overstriking is reminded user.

Response detects indication for the second time, as shown in Figure 16 (c), in the time that detects the thermal-image data frame that is greater than the second correlative value and the 3rd correlative value, show the customizing messages that dynamic infrared thermal imagery is relevant with detected thermal-image data frame, this customizing messages comprises the infrared thermal imagery 1602 and 1603 that this thermal-image data frame generates etc., at this, because the corresponding degree of correlation of infrared thermal imagery 1602(is less than infrared thermal imagery 1601, and its evaluation of estimate is greater than infrared thermal imagery 1601), because the corresponding degree of correlation of infrared thermal imagery 1603(is greater than infrared thermal imagery 1601, and its evaluation of estimate is less than infrared thermal imagery 1601), so, selection portion 11B keeps these two relevant customizing messages of thermal-image data frame, and the correlative value renewal 11E of portion will, according to the corresponding evaluation of estimate of infrared thermal imagery 1602 (80%), upgrade the 3rd correlative value, and according to the corresponding degree of correlation of infrared thermal imagery 1603 (85%), the second correlative value is upgraded, the announcement information that the customizing messages that notification unit 11D obtains the thermal-image data frame that makes display part 10 show that these two of detecting are different from multiframe part generates.At this moment, because the customizing messages such as infrared thermal imagery 1602,1603 corresponding thermal-image data frames remain on interim storage part 2, the information that user can show from display part 10, as infrared thermal imagery 1602,1603, is selected the follow-up corresponding thermal-image data frame that records.

Response detects indication for the third time, and, as shown in Figure 16 (d), in the time that degree of correlation detecting is greater than the second correlative value and evaluation of estimate and is greater than the thermal-image data frame of the 3rd correlative value, selection portion 11B keeps the customizing messages relevant with infrared thermal imagery 1604, or also infrared

thermal imagery

1602,1603 relevant customizing messages is deleted; And the correlative value renewal 11E of portion will, according to the corresponding degree of correlation of infrared thermal imagery 1604 (95%) and evaluation of estimate (95%), upgrade second, third correlative value; Notification unit 11D will make display part 10 show the customizing messages that dynamic infrared thermal imagery is relevant with detected this thermal-image data frame, and this customizing messages comprises the infrared thermal imagery 1604 that this thermal-image data frame generates etc.

Like this, selection portion 11B, the comparative result of the 11A of portion based on the comparison, selects and keeps the value of the degree of correlation and/or evaluation of estimate to be greater than the relevant customizing messages of thermal-image data frame of the correlative value (the second correlative value, the 3rd correlative value) of regulation; Or also in the interface of display part 10, the information that thermal-image data frame that always can the display notification degree of correlation is the highest and/or evaluation of estimate is the highest obtains, helps greatly user's shooting.

As mentioned above, in the present embodiment, not only can obtain the effect of embodiment 3, and, be provided with according to provisioning information and the supplementary of the specific shot body heat picture detecting, be used as the factor of comparison, in the time more excellent thermal-image data frame being detected, selection portion 11B selects and keeps the relevant information of this thermal-image data frame, and the correlative value renewal 11E of portion upgrades accordingly to correlative value, thereby can choose the more preferably relevant customizing messages of thermal-image data frame; Can reach the operation easier that further attenuating vision is aimed at, improve the quality of the thermal-image data frame while shooting, the beneficial effect of prompting particular state, common user easily grasps this shooting technical ability, and random shooting is also easy to obtain high-quality thermal-image data frame.Certainly, arbitrary product of enforcement embodiments of the present invention might not need to reach above-described all advantages simultaneously.

In addition, although exemplified three correlative values, also more correlative value, evaluation of estimate and/or the supplementary that corresponding several differences stress and/or detect the provisioning information obtaining, the evaluation of estimate for example being obtained by position, size, the angle of inclination of specific shot body heat picture, the evaluation of estimate being obtained by assay value, environment temperature etc. etc.

In addition,, although exemplified multiple correlative values (three, or also can be reduced to two) in embodiment 2, wherein part is upgraded, part do not upgrade; But also can be configured to update all; Or also can remove the structure of the correlative value renewal 11E of portion, and prepare multiple corresponding correlative values in advance, all do not upgrade.

In embodiment 3, introduce according to the value of the degree of correlation and evaluation of estimate as example, also according to obtaining multiple evaluations of estimate according to the detected provisioning information of test section 8, the comparison according to multiple evaluations of estimate with corresponding correlative value, determines whether carrying out selection and the maintenance of customizing messages; Or, also will notify multiple thermal-image data frames that obtain according to different evaluations of estimate; Or, also the value of the degree of correlation and multiple evaluation of estimate are notified according to order or priority level.And preferred, the relevant customizing messages of regulation thermal-image data frame of up-to-date selection portion 11B selection (normally the degree of correlation and/or evaluation of estimate are greater than correlative value) is notified.Like this, user is very convenient; For example heat is determined to position, size, the degree of tilt of subject, the value of the degree of correlation, as factor of evaluation, be convenient to obtain the thermal-image data frame of high-quality thermal-image data frame or specific photographing request; Using the value of thermal imagery assay value, the degree of correlation as factor of evaluation, be convenient to obtain subject analysis conditions in time.User is easy to hold and recognize the focus such as quality of shooting, even if random shooting also can obtain and record the thermal-image data frame of high-quality.

And, in the time the thermal-image data frame that is greater than the previous degree of correlation and/or evaluation of estimate being detected, the customizing messages that selection portion 11B obtains thermal-image data frame is before deleted, but also can continue to keep, at this moment, notification unit 11D also can show the relevant customizing messages of multiple thermal-image data frames, for example according to height of the degree of correlation and/or evaluation of estimate etc. because of these customizing messages of sequencing display usually.Notification unit 11D, the relevant customizing messages of regulation thermal-image data frame of selecting according to selection portion 11B and/or the lastest imformation of the correlative value renewal 11E of portion (can be the action of upgrading, can be also the information etc. of the correlative value after upgrading) are notified,
