Problems solved by technology

[0004] However, the above method requires the user to visually judge the matching degree of the reference image and the thermal image of the subject, and the user is prone to visual fatigue; when using a handheld thermal imaging device, the operation of aligning and shooting is easy Fatigue, repeated aiming prolongs the shooting time and affects the quality of the thermal image captured
Moreover, this method is rigid in operation and has high requirements for shooting alignment

Embodiment approach 1

[0039] The thermal imaging device 100 (infrared matching and updating device 100 ) of Embodiment 1 is based on the thermal image data frames captured by the shooting unit 1 and stored in the temporary storage unit 2 in multiple frames of thermal image data frames (here thermal image signal frames) , according to a prescribed instruction, detect the correlation between the multiple frames of thermal imaging data stored in the temporary storage unit 2 and the subject identification information, and the thermal imaging device 100 based on the obtained thermal imaging data greater than the prescribed contrast value frame information to inform the user.

[0040] figure 1 It is a block diagram showing the schematic configuration of the thermal imaging device 100 as an example of the infrared matching updating device 100 according to the first embodiment of the present invention.

[0041] Specifically, the thermal imaging device 100 has a photographing unit 1, a temporary storage un...

Embodiment approach

[0050] The image processing unit 7 is used to perform prescribed processing on the thermal image signal captured by the imaging unit 1 to obtain image data of the infrared thermal image. Specifically, for example, the image processing unit 7 performs prescribed processing such as non-uniformity correction and interpolation on the thermal image signal captured by the photographing unit 1, performs pseudo-color processing on the thermal image signal after the prescribed processing, and obtains an infrared thermal image Data; an implementation of pseudo-color processing, for example, according to the range of the thermal image signal (AD value) or the setting range of the AD value to determine the corresponding range of the pseudo-color table, and the corresponding range of the thermal image signal in the range of the pseudo-color plate The specific color value is used as the image data of its corresponding pixel position in the infrared thermal image. The image data obtained aft...

Embodiment 2

[0135] The difference from Embodiment 1 is that the thermal imaging device 100 (infrared matching update device) detects the multi-frame thermal imaging data frames stored in the temporary storage unit 2 according to the specified instructions. The specified information related to the thermal image of the specific subject in the image data frame; wherein, the specified information includes at least one or any of the position, size, inclination angle, and correlation value of the thermal image of the specific subject combined information. The control unit 11 has an auxiliary information acquisition unit (not shown) for acquiring auxiliary information; a comparison unit 11A for comparing the predetermined information obtained by the detection unit, the auxiliary information obtained by the auxiliary information acquisition unit, and the information obtained by the detection unit 8 . One or more of the evaluation value obtained by the prescribed information, the evaluation value ...

Abstract

The invention provides an infrared matching updating device and an infrared matching updating method and relates to the application field of a thermal image device, a thermal image processing device and infrared thermal imaging detection. According to a thermal image device in the prior art, during shooting, a thermal image of an object under shooting is shot based on the subjective experience of a user, so that the workload is heavy and the quality of the thermal image is hard to guarantee. According to the infrared matching updating device and the infrared matching updating method provided in the invention, a reference image and the infrared thermal images are displayed jointly; when a detection indication is responded, prescribed information of thermal images of a specific object under shooting in a plurality of frames of thermal image data frames in a storage medium can be detected; or with the factor of auxiliary information taken into consideration, and in the comparison of prescribed comparison values, the prescribed comparison values are updated based on prescribed conditions, so that the optimal thermal image data frame can be obtained by comparison of the thermal image data frames obtained continuously; further processing or operation, such as selection, notification, analysis and storage and the like can be carried out favorably; and the shooting operation is simple and the quality of the thermal image is good.

Description

technical field [0001] The infrared matching updating device and the infrared matching updating method of the present invention relate to various thermal imaging devices for handheld shooting or online shooting, thermal image processing equipment for receiving and processing thermal images, and the application field of infrared detection. Background technique [0002] Since the application of thermal image detection technology, users have been confused about the cognition of the correct shooting position, the imaging form of the subject under the shooting angle, and the control of the shooting distance. These depend on the user's subjective ideas and experience. To ensure the quality of the inspection, you need to think while shooting. The shooting speed is very slow. If you speed up, it is easy to miss key shooting parts or object defects, which will affect the effect of status evaluation. It usually takes several years of practice accumulation before the user can reach a h...
