Abstract

This application relates to a new infrared ultra-weak moving target detection method. The method includes: acquiring an infrared image sequence to be detected, respectively suppressing the background of overlapping regions and non-overlapping regions between frames in the infrared image sequence, obtaining a target image sequence, performing target enhancement on moving targets in the target image sequence, and suppressing the target image sequence. The background residual in the image sequence is obtained to enhance the target image sequence, and the candidate target set of the enhanced target image sequence is determined by adaptive threshold segmentation, and the target motion speed and gray-scale appearance feature of each candidate target in the candidate target set are calculated, Identify the true objects in the set of candidate objects. The method can realize the detection of the ultra-weak moving target.

Description

technical field [0001] The present application relates to the technical fields of computer vision and image processing, in particular to a method for detecting infrared ultra-weak moving targets. Background technique [0002] With the development of computer vision and image processing technology, the accuracy of target tracking and detection is required to be higher and higher. In recent years, infrared detection-related hardware and software algorithms are in a state of continuous development. Existing methods use different image information to achieve target detection, which can be generally classified into two types based on single-frame images and sequence images. [0003] (1) Infrared weak and small target detection based on single frame image [0004] Infrared weak and small target detection method based on a single frame image mainly utilizes the characteristic difference between the target and the background in the image to realize the detection of weak and small t...
