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 specific subject, and the user is prone to visual fatigue; when using a handheld thermal imaging device, the operation of aligning and shooting Easy to 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

[0026] The thermal imaging device 100 (thermal image selection device) of Embodiment 1 is based on the thermal image data frames captured continuously by the shooting unit 1, and detects the correlation between the acquired thermal image data frames and the object identification information, etc., based on the comparison As a result, the specific information about the optimal (eg, maximum correlation) frame of thermal imaging data is selected.

[0027] figure 1 It is a block diagram showing a schematic configuration of a thermal imaging device 100 as an example of the thermal image selection device according to Embodiment 1 of the present invention.

[0028] 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 , a...

Embodiment approach

[0037] The image processing unit 7 is used to perform prescribed processing on the thermal image data frames captured by the imaging unit 1 to obtain image data of infrared thermal images. 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 AD value of the thermal image data frame or the setting range of the AD value to determine the corresponding range of the pseudo color table, the thermal image data in the range of the pseudo color plate The corresponding specific color value is used as the image data of the corresponding pixel position in the infrared thermal image. The image data obtain...

Embodiment 2

[0114] Embodiment 2, the difference from Embodiment 1 is that the detection unit 8 of the thermal imaging device 100 detects the thermal image data frames that are related to the specific subject The prescribed information related to the body thermal image; the control unit 11 has an auxiliary information acquisition unit (not shown), which is used to acquire auxiliary information; Among the information, the evaluation value obtained by detecting the predetermined information obtained by the detection unit, the evaluation value obtained by the auxiliary information obtained by the auxiliary information obtaining unit, and the evaluation value obtained by detecting the predetermined information obtained by the detection unit and the auxiliary information obtained by the auxiliary information obtaining unit One or more items are compared with the corresponding one or more comparison values; the selection part 11B, based on the comparison result of the comparison part 11A, selects...

Abstract

Disclosed are a thermal image selecting apparatus and a thermal image selecting method. The thermal selecting apparatus comprises: a shooting portion (1), used for continuously shooting and obtaining a thermal image data frame; a detecting portion (8), used for detecting specified information related to a thermal image of a specific shot object according to the continuously obtained thermal image data frame; a comparing portion (11A), used for comparing an evaluation value with a specified comparison value, the evaluation value being obtained based on the specified information detected by the detecting portion and / or the specified information obtained in the detection; and a selecting portion (11B), selecting specific information related to a specified thermal image data frame according to a comparison result of the comparing portion. Further disclosed is the thermal image selecting method using the thermal image selecting apparatus. Therefore, the shooting operation is simple, the shooting speed is high, and the quality of the thermal image is high.

Description

technical field [0001] The thermal image selection device and thermal image selection 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 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 higher detection level. [0003] Those skilled in the art have been trying to solve this problem. There is such a technology that continuously overlaps and displays the...
