Target tracking method and device for space-based surveillance scene

Abstract

The invention provides a target tracking method and a device for space-based surveillance scene. The method provided by the invention, includes obtaining the video to be tracked of the target object in real time, extracting a first frame and a second frame, clipping a first frame to obtain a first region of interest image, clipping the second frame to obtain a target template image and a second region of inter image, inputting a target template image and a first region of inter image to an appearance tracker network, inputting the first region of interest image and the second region of interest image into the motion tracker network to obtain the motion tracking position, finally, inputting the appearance tracking position and the motion tracking position into the depth fusion network to obtain the final tracking position. The target tracking method provided by the invention utilizes the appearance and motion information of the target object to carry out positioning tracking through themethod of parallel connection of two tracker networks, and then fuses the two positioning information, thereby realizing real-time tracking of the target object.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a target tracking method and device for space-based surveillance scenarios. Background technique [0002] Target detection and tracking are two core tasks in the field of visual surveillance. Among them, tracking aims to achieve precise positioning of targets in continuous video frames to obtain target trajectories, which has extremely high application value in actual space-based surveillance scenarios. [0003] In the traditional visual surveillance method, the surveillance data is often collected by using a fixed or low-angle camera. With the rapid development of UAV technology in recent years, surveillance based on airborne air-based camera data has become more common and important. This kind of space-based surveillance data has the advantages of high viewing angle, less occlusion, large coverage area, fast and flexible deployment, and low maintenance cost. However, at th...

Problems solved by technology

[0005] The present invention provides a target tracking method and device for space-based surveillance scenes to solve the problem that the high viewing angle of surveillance data based on airborne space-based camera data may easily lead to small target size, insufficient appearance information, and the space-based platform is flexible. The mobile deployment leads to variable and uncertain types of targets that may appear in the surveillance scene, and the collected surveillance video contains certain camera movements, which affects the technical problems of the reliability of the target motion characteristics in the video
