Abstract

A real-time detection tracking method for a moving object of a space-borne satellite image belongs to the technical field of the satellite image and in particular relates to a detection tracking method for the moving object of the space-borne satellite image. The invention can solve the problems of error tracking caused by a lot of moving noisy points brought by image stabilization, tracking lossrate during multi-target tracking and performance of a detection tracking algorithm. The algorithm breaks through the performance bottleneck, and is capable of realizing real-time monitoring of a space-borne satellite and reducing the labor cost; an abnormal condition can be warned in time through a precise detection tracking result, man power is not needed for monitoring all the time, and the method can be applied to the military field for detection tracking of the moving object such as an aircraft carrier and a warship.

Description

technical field [0001] The invention belongs to the technical field of satellite image acquisition, and in particular relates to a method for detecting and tracking a moving object in a spaceborne satellite image. Background technique [0002] The moving target detection and tracking algorithm is to detect the moving target we are interested in in each image of the video image, and track the same target in different frames. The traffic scene in satellite-borne satellite images is complex, including highways and overpasses; the road background is complex, with trees beside the road, residential buildings and other buildings; camera shake cannot be completely removed; the image resolution is super large, but the target object to be detected is small; Most of them are gray and white, with less information and less obvious features. The existing detection and tracking algorithms for moving targets in satellite images generally have problems such as low detection rate, poor trac...
