A visible light target tracking method for real-time anti-smoke interference of an optoelectronic pod

Abstract

A visible light target tracking method for real-time anti-smoke interference of an optoelectronic pod relates to the technical field of optoelectronic detection and tracking, and comprises the following steps: S1, entering an initialization stage, recording a target test starting moment, calculating a correlation coefficient and a texture intensity average value of the target in a plurality of frames of images in an early stage, and setting a loss judgment threshold value; S2, entering normal tracking, frame by frame calculating the correlation coefficient and the texture intensity of the target, dynamically adjusting the threshold value, and updating a template according to a condition, and judging whether the target is lost through three conditions; S3, after judging that the target is lost, entering a loss tracking stage, locking a target region by using geography, resetting a recapture number, and determining whether to start recapturing according to a target loss duration; and S4, in the recapturing stage, matching by using an initial template, accumulating a recapturing success number according to the threshold value, and continuously meeting the standard to determine that recapturing is successful, and exiting a target test state. The application can solve the technical problems of inaccurate target tracking loss judgment and recovery and real-time caused by smoke interference when platform resources are limited.
