The present invention relates to a background motion estimation method, device and storage medium for an infrared image sequence. The method includes: determining the area to be matched according to the maximum displacement of two adjacent frame images in the background motion, and dividing the area to be matched into T subsections. In these sub-regions, use a random method to generate M sub-window sets, use the synchronous mutual information matching method to calculate the background motion displacement corresponding to these sub-window sets, and then use the potential function according to the background motion displacement corresponding to these sub-window sets The voting method calculates the background motion displacement between two adjacent frames of images. The method of the invention is based on image block matching and does not rely on the extraction of feature points, so it has high robustness for background motion estimation of infrared image sequences with few feature points and disturbed by noise.
Description
technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a background motion estimation method, device and storage medium for infrared image sequences. Background technique [0002] Infrared target detection technology has very important applications in infrared early warning, automatic navigation and other technical fields, especially in the detection of weak and small targets in infrared images. There are bright spots of one to a dozen pixels, no obvious texture features, and a lot of noise interference, which brings great difficulties to the detection of small infrared targets. Therefore, when the background is relatively static, the background subtraction method is often used to detect the target, but when the camera is tracking the target and the background moves, it is necessary to perform background motion estimation to perform corresponding motion compensation to keep the background relative still. Theref...
