Problems solved by technology

[0005] However, the above method requires the user to manually judge the matching degree of the reference image and the thermal image of the subject, and the user is prone to visual fatigue, which affects the shooting speed
[0006] Moreover, the reference image has relatively large limitations on the user's shooting, such as a certain occlusion of the infrared thermal image, and has relatively large restrictions on the thermal image position, size, and angle of the thermal image of the subject, which increases the inconvenience to users

Embodiment approach 1

[0029] The thermal imaging device 100 of Embodiment 1 is based on the thermal image data frames captured by the shooting unit 1, and sequentially detects the correlation between the obtained thermal image data frames and the object identification information, and the thermal imaging device 100 is based on the detected The location of the thermal image of a specific subject is generated, a logo is generated, and the user is notified.

[0030] figure 1 It is a block diagram showing a schematic configuration of a thermal imaging device 100 as an example of a thermal image matching device according to Embodiment 1 of the present invention.

[0031] Specifically, the thermal imaging device 100 has a photographing unit 1, a temporary storage unit 2, a flash memory 3, a communication I / F 4, a memory card I / F 5, a memory card 6, an image processing unit 7, a detection unit 8, a display control unit 9, The display unit 10 , the control unit 11 , the operation unit 12 , and the control...

Embodiment approach

[0040] The image processing unit 7 is used to perform prescribed processing on the thermal image data frame (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 data frame captured by the photographing unit 1, performs pseudo-color processing on the thermal image data frame after the prescribed processing, and obtains an infrared thermal image. image data; an implementation of false color processing, for example, according to the range of the thermal image data frame AD value or the setting range of the AD value to determine the corresponding range of the pseudo color table, the thermal image data is corresponding to the range of the pseudo color plate The specific color value of is used as the image data of the corresponding pixel position in the infrared thermal image...

Embodiment 2

[0087] The difference between Embodiment 2 and Embodiment 1 is that the detection unit 8 is configured to detect the specified information of the thermal image of a specific subject in the thermal image data frame based on the acquired thermal image data frame; The image processing unit 7, according to the specified information obtained by detection by the detection unit 8, generates a logo that embodies the same or different morphological effects, and the logos of different morphological effects include at least color, line shape, thickness, transparency rate, shape, content ( Such as different color composition, etc.), flickering state, brightness, composition data, position, size, rotation angle, prompt information, preferably, the outline of the object and the analysis area corresponding to the object are used. Wherein, the specified information includes at least one of the position, size, inclination angle, analysis value, and correlation value of the thermal image of the ...

Abstract

Disclosed are a thermal image matching apparatus and a thermal image matching method. The thermal image matching apparatus comprises: an obtaining portion (1), used for shooting and obtaining a thermal image data frame; a detecting portion (8), used for detecting, according to the obtained thermal image data frame, whether a thermal image of a characteristic shot object exists; and an image processing portion (7), used for generating, according to a detection result of the detecting portion and on the basis of the obtained thermal image data frame, an infrared thermal image carrying an identification indicating a location of the thermal image of the specific shot object in the infrared thermal image. Further disclosed is the thermal image matching method using thermal image matching apparatus.

Description

technical field [0001] The thermal image matching device and the thermal image matching method of the present invention relate to the application field of infrared detection. Background technique [0002] Since the application of thermal image detection technology, users have been confused about the correct shooting position, the imaging shape of the subject under the shooting angle, etc., which depends on the user's subjective ideas and experience. 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 higher detection level. [0003] Those skilled in the art have been trying to solve this problem. Recently, some methods that are expected to reduce the technical difficulty of thermal image shooting and increase the shooting speed are known. [0004] There...
