Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] like figure 1 As shown, the flow chart of the infrared image stitching method of the present invention is provided, which includes the following steps:

[0018] a). To collect infrared images, according to the order of "Z", use the infrared thermal imager to sequentially collect partial infrared images of the object to be tested, and ensure that two adjacent partial infrared images have an overlapping area of ​​20% to 30%;

[0019] b). Find the matching feature area, calculate and find whether there are three pairs of matching feature areas in two adjacent partial infrared images, if three pairs of matching feature areas can be obtained, then perform step c), if not get three pairs of corresponding matching features area, then perform step d);

[0020] The previous infrared image to be spliced ​​is called the initial image, and the latter infra...

Abstract

The invention relates to a method for mosaicing infrared images. The method comprises the following steps of (a) collecting the infrared images, and ensuring that the two adjacent images have a 20% to 30% overlapping area; (b) finding matched feature areas, wherein if three pairs of matched feature areas exist, carrying out step (c), and if the three pairs of matched feature areas do not exist, carrying out step (d); (c) mosaicing the infrared images; (d) manually selecting the matched feature areas; and (e) judging whether the mosaicing is completed or not. In the step (b), a 4*4 pixel is used as a window to scan the two images, and if the average value of the difference of the gray-level values of all pixel points of the scanned window is within five gray-level values, the two images are considered as the matched feature area. The method for mosaicing the infrared images has the advantages that the high efficiency of the image mosaicing is ensured, and the defect of the automatic mosaicing that the matched feature areas cannot be found is avoided; the quick mosaicing of the batch infrared images is realized; and the related detection by using the infrared images is more convenient, quick and visual.

Description

technical field [0001] The present invention relates to an infrared image mosaic method, more specifically, to an infrared image mosaic method applied in a large field of view scene, and an infrared image mosaic method that automatically stitches and can manually select matching feature regions is preferred. Background technique [0002] In the current digital age, infrared digital image technology has been applied to many fields. As an important technical means and hotspot of infrared image processing, infrared image stitching is an indispensable and important part of infrared technology. In many occasions, infrared imaging equipment can only obtain scene images with a small field of view due to reasons such as low resolution of imaging devices; for example, in the process of collecting indoor or outdoor infrared images of It is a partial image, and the infrared image needs to be spliced ​​to obtain a panoramic infrared image. [0003] Due to the special imaging mechanism...
