In addition, it is not shown that control part 11 possesses position setting unit 11G(), the location parameter (position, or also comprise size, or also comprise the anglec of rotation) of display part is arranged in for arranging reference picture.Preferably, position setting unit 11G is arranged in the location parameter of infrared thermal imagery for arranging reference picture; Such as, according to the self-adaptation viewing area specified in infrared thermal imagery, in this adaptive region, maximize the location parameter of display placed in the middle according to calculated reference picture, thus the location parameter that reference picture is arranged in infrared thermal imagery is set; Such as, also according to the incidental parameter of reference picture (such as embodying the location parameter in infrared thermal imagery), the location parameter that reference picture is arranged in infrared thermal imagery can be set according to this parameter; Or, also the location parameter that reference picture is arranged in infrared thermal imagery can be set according to the configuration of thermal image device 100 (placed in the middle, original size); Or, also can according to the location parameter of user's input.
Operating portion 12: carry out various instruction operation for user, or input the various operations such as set information, control part 11, according to the operation signal of operating portion 12, performs corresponding program.With reference to figure 2, operating portion 12 is described, the button providing user to operate has that record key 1, focusing key 2, acknowledgement key 3, playback key 4, menu are strong 5, directionkeys 6 etc.; In addition, touch-screen 7 or speech recognition component (not shown) etc. also can be adopted to realize the operation of being correlated with.
The change of the display interface in shooting process is described with reference to figure 6, the control flow of the detecting pattern of thermal image device 100 is described see Fig. 7.The subject of this application scene thermal image device 100 pairs of transformer stations as hand-held in user is taken.Control part 11 is based on the control program stored in flash memory 3, and the various data used in each several part control, controls the action of the entirety of thermal image device 100 and performs the control of various modes process.After being powered up, control part 11 carries out the initialization of internal circuit, then, enter standby screening-mode, namely shoot part 1 is taken and is obtained thermal-image data, the thermal-image data that shoot part 1 is taken acquisition by image processing part 7 carries out the process specified, be stored in interim storage part 2, display part 10 shows infrared thermal imagery continuously with dynamic image form, in this state, control part 11 is implemented it and is controlled, and whether persistent surveillance has been switched to the process of other patterns according to scheduled operation or has carried out power-off operation, if had, then enter corresponding processing controls.The rate-determining steps 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 the image space in the morphological feature of specific shot body heat as IR1 and the infrared thermal imagery at its place in the past, size, angle, for ensureing shooting quality specification, detecting pattern is selected by the scheduled operation of operating portion 12, control part 11 is based on the table 3 stored in flash memory 3, the subject indication information that subject information generates is presented at display part 10, when user is according to the subject " subject 1 " of floor, selected " subject 1 " shown on display part 10 by operating portion 12, reference picture specifying part 11F is according to the selection of user, just determine reference picture T1, the composition data of reference picture T1 is read from flash memory 3, 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.Such as, according to attached location parameter, the location parameter that reference picture T1 is arranged in infrared thermal imagery is set.In addition, also can self-adaptation viewing area according to the rules, or the location parameter that user specifies, 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, according to the selection " subject 1 " of user, just determines the subject identifying information for coupling, at this, assuming that with reference to image T1 as the template image calculating the degree of correlation.(in addition, also can read the subject identifying information that template data 301 is used as calculating the degree of correlation from flash memory 3).
Steps A 03, obtain thermal-image data frame, thermal-image data frame shoot part 1 being taken acquisition is sent to interim storage part 2, image processing part 7 carries out predetermined processing such as pseudo-color conversion to obtained thermal-image data frame, obtain the view data of infrared thermal imagery, and, determined composition data is obtained the view data of reference picture T1 by combining unit 7A according to the given size arranged, according to set assigned position, carry out synthesizing (overlapping) with the view data of the infrared thermal imagery generated, leave the view data of synthesis 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 obtained, with this, constantly show dynamic composograph.
Then, in steps A 04, read the thermal-image data frame such as obtained by shoot part 1 shooting immediately in interim storage part 2, detection window setting unit, arranges detection window.Such as, based on the upper left corner of the surveyed area G1 of regulation, first detection window is provided with;
Steps A 05, carries out the process of the relatedness computation between thermal-image data in detection window and subject identifying information.
Test section 8, based on the detection window set by detection window setting unit, extracts the thermal-image data being arranged in this detection window, according to the template that feature registration unit is registered, calculates the degree of correlation therebetween.Such as, according to the profile of the specific shot body heat picture that the thermal-image data in detection window extracts, with the silhouette contrast of contour images T1, calculate the ratio sum of overlapping area in the respective total area therebetween; The value of the degree of correlation can be obtained thus;
Further, in steps A 06, the value of the degree of correlation obtained is stored.
In steps A 07, when test section 8 judges to arrange detection window in thermal-image data frame, whether calculate the degree of correlation for all detection windows.If residue does not also calculate the region (being no in steps A 07) of the degree of correlation, get back in steps A 04, detection window setting unit is in a predetermined direction by the position of detection window skew intended pixel number, this position is set to the next position of detection window, and repeats follow-up process.
In addition, from thermal-image data frame, search is with like template class during frame part, for amplify and reduce and by detection window after detection window J1 inclination predetermined angular time, also carry out the check processing of similar above-mentioned explanation.
If all detection windows for thermal-image data frame calculate the degree of correlation (being yes in steps A 07), then the value (or also by the location parameter of corresponding detection window) of the maximum relation degree detected is remained on 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, then represent the similarity degree of specific shot body heat picture in the thermal-image data frame of current detection and contour images T1, the correlative value obtained before not being better than; Get back to steps A 03, repeat follow-up process; Also can be configured to steps A 12, as do not exited, getting back to A03; At this, user is by changing shooting distance, image space, the angle between the optics of position and the adjustment thermal image device 100 of taking and specific shot body heat picture, and the adjustment along with user operates, and repeats follow-up process.When the degree of correlation detected in steps A 09 is greater than the correlative value of the degree of correlation, then 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 (such as will judge whether the judgment value detecting that whether specific shot body heat picture mates with subject identifying information, correlative value as the initial degree of correlation), when the value detecting the degree of correlation obtained is greater than this judgment value, represent the degree of correlation of specific shot body heat picture detected and be better than prepared judgment value, then by correlative value that the value that this judgment value replaces with current the detected degree of correlation obtains; As the correlative value of the subsequent detection degree of correlation, the specific shot body heat picture that the degree of correlation is higher whether can be obtained so that follow-up.In the present embodiment, the correlative value of the initial degree of correlation of thermal image device 100 is 72%, this initial correlative value is the judgment value judging whether to detect specific shot body heat picture, if the degree of correlation of the thermal-image data frame obtained is less than this correlative value, then represents in this thermal-image data frame and specific shot body heat picture do not detected; Its effect be when user repeatedly take also cannot obtain the announcement information relevant with selected customizing messages time, mean whether have taken mistake subject.So, in Fig. 6 (a), because the value of the detected degree of correlation is less than 72%, do not show announcement information, and show " not mating " printed words.
In addition, the correlative value of the degree of correlation, also can not prepare in advance, at this moment, such as, when the value of the degree of correlation of the thermal-image data frame that first time is detected, as the correlative value of the value of the degree of correlation of subsequent detection thermal-image data frame acquisition, when subsequent detection is to when being greater than this correlative value, then replace this correlative value.
At this, whether to be greater than correlative value for evaluating the example of the foundation of the degree of correlation, but also to have and be less than correlative value or close to the situation of correlative value (pre-prepd judgment value) as the evaluation degree of correlation etc.Further, correlative value can be the value of the degree of correlation, also can be that the value of the degree of correlation is passed through (accordingly, the value of the degree of correlation of detection acquisition compare with correlative value after should converting) such as the values of the acquisition that converts.
Steps A 10, correlative value update section 11C, by according to the detected value with maximum relation degree, upgrades the correlative value of the degree of correlation, and, using the correlative value after upgrading as the correlative value of the comparison degree of correlation of follow-up thermal-image data frame.The degree of correlation as the thermal-image data frame when the maximum relation degree detected is 80%, replaceable former correlative value 72%.
Steps A 11, selection portion 11B, by customizing messages such as thermal-image data frames corresponding for the detected value with maximum relation degree, remains on the regulation region of interim storage part 2, the customizing messages (if there is) before replacing it.In addition, the customizing messages that multiple thermal-image data frames of specified quantity are relevant can also be kept, the customizing messages such as the 3 frame thermal-image data frames that such as the maintenance degree of correlation is the highest and the value of the degree of correlation thereof.
Further, relevant to the thermal-image data frame that the selected degree of correlation is maximum customizing messages notifies.
Such as, by the image that this thermal-image data frame obtains, the dynamic infrared thermal imagery generated with the thermal-image data frame of follow-up acquisition, reference picture show jointly.Further, the customizing messages kept, before the instruction not receiving customizing messages that selection portion 11B reselects or user, will be maintained in interim storage part 2 always.
As shown in Fig. 6 (b), but being not limited to and showing the infrared thermal imagery 601 that reduces, also can be other mode, such as direct by calculate the degree of correlation obtained value display (in one example in which, as direct display pixel value difference and numerical value etc.).In addition, also display Dynamic IR thermal imagery can be switched to the freeze frame of this thermal-image data frame of display; Preferred mode, also can notify the detected region (or location parameter etc. of subject) with the detection window of maximum relation degree.The mark etc. with the position of the subject thermal imagery of maximum relation degree that such as signal detects in the infrared thermal imagery freezed.Maybe display Dynamic IR thermal imagery is switched to the freeze frame of this thermal-image data frame of display, then, the instruction of response user, switch the display state of state infrared thermal imagery of reversing again, or the state that the thermal-image data frame of the image that obtains of this thermal-image data frame and follow-up the acquisition dynamic infrared thermal imagery, the reference picture that generate show jointly.In addition, the infrared thermal imagery that this thermal-image data frame obtains can not also be shown, and display reminding information; Or with vibration, pilot lamp flicker etc., the mode that various user can discover.Further, when selection portion 11B is configured to instruction maintenance multiframe thermal-image data frame, such as, can shows the infrared thermal imagery reduced of dynamic infrared thermal imagery and the acquisition of multiple kept thermal-image data frame simultaneously, such as, also carry out sequencing display according to the height of the degree of correlation.
Note, when not contrasting with the correlative value (representing the judgment value whether specific shot body heat picture mates with subject identifying information) judging 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.
Further, be not limited to and the customizing messages notified selected by selection portion, the event that also can upgrade correlative value or also notify correlative value further.
Steps A 12, judges whether to exit, and as do not exited, then getting back to steps A 03, repeating follow-up process.At this moment, due in steps A 11, the correlative value of the degree of correlation is upgraded, therefore, at the thermal-image data frame that follow-up shooting obtains, by with upgrade after the correlative value of the degree of correlation compare, further, when being greater than the correlative value of the degree of correlation, kept customizing messages is replaced.
In the example of an advice method, the initial correlative value due to the degree of correlation is 72%; As shown in Fig. 6 (a), when the value of the detected degree of correlation is less than 72%, there is no to show the customizing messages being used for notifying, as " not mating " printed words can be shown.As shown in Fig. 6 (b), in shooting, to convert the information obtained according to the ratio sum of overlapping area when the maximum relation degree first detected is 80%(), using the correlative value correlative value 72% of the degree of correlation (replace) of the value of this degree of correlation as the degree of correlation of follow-up comparison, and show with Dynamic IR thermal imagery, reference picture the infrared thermal imagery 601 reduced that selected thermal-image data frame obtains simultaneously.When subsequent detection is greater than 80% to the value of maximum relation degree, as shown in Fig. 6 (c), the value of the degree of correlation is 95%, then replace the correlative value 80% of the degree of correlation, as the correlative value (95%) of the new degree of correlation, selection portion 11B, by customizing messages such as the thermal-image data frames of detected value 95% correspondence with maximum relation degree, remains on the regulation region of interim storage part 2, the customizing messages before replacing it; Show the infrared thermal imagery 603 reduced that selected thermal-image data frame obtains with Dynamic IR thermal imagery, reference picture simultaneously; By that analogy, when the value of the detected degree of correlation is 95%, display is as shown in Fig. 6 (c), if user is satisfied, can stop taking the aiming of subject, because this thermal-image data frame remains in interim storage medium such as storage part 2 grade, the process such as follow-up analysis, storage or operation conveniently can be carried out.At this moment, if user presses record key, then the process (as compression etc.) being carried out by the thermal-image data frame of infrared thermal imagery 603 correspondence specifying is recorded to storage card 8.And, even if the not mode of display reminding information or infrared thermal imagery, the mode of such as pilot lamp flicker, because this thermal-image data frame remains in interim storage medium such as storage part 2 grade, can be configured to user press acknowledgement key or record key time, carry out showing, the process such as record.
Further, also can notify the information upgrading correlative value, and not notify the information of thermal-image data frame.
And, when some is applied, to whether specific shot body heat picture being detected, be not limited to comparing between the value of the degree of correlation and the correlative value of the degree of correlation, also can be deformed into such as according to detecting the provisioning information and/or the evaluation of estimate of provisioning information acquisition and the comparative result of predetermined correlative value that obtain, being used as foundation specific shot body heat picture whether being detected.
As mentioned above, in the present embodiment, display reference picture assists shooting, and when the thermal-image data frame of the degree of correlation higher than fiducial value being detected, just selecting this thermal-image data frame or also being notified, and follow-up whenever the correlative value higher than the degree of correlation before being detected, can correlative value be constantly updated, and the information notified, the operation easier significantly reducing vision and aim at can be reached, significantly reduce the physical strength of shooting, improve the beneficial effect of the quality of the final thermal-image data frame obtained.Common user easily grasps this shooting technical ability.Certainly, the arbitrary product implementing embodiments of the present invention might not need to reach above-described all advantages simultaneously.
Further, 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 obtained is not necessarily high; Therefore, preferably, the provisioning informations such as the value of the consideration position of specific shot body heat image position in thermal-image data frame, size, angle of inclination, the degree of correlation, such as obtain evaluation of estimate (can be the evaluation of estimate that one or more provisioning information obtains) according to afore mentioned rules information, compare with the correlative value of regulation, as the factor that the selection and carrying out carrying out regulation thermal-image data frame notifies, 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 process.
