Method of generating initial tracking frame of UAV target based on computer vision point

Abstract

The invention relates to the field of computer vision technology, which discloses a method for generating an initial tracking frame of an unmanned aerial vehicle target based on computer vision points, and solves the problem that the initial frame may contain too much useless background information in the way of artificially setting the tracking frame in the traditional technology Issues that cause noise or contain insufficient useful information to affect accuracy. In the present invention, after the target point is manually selected by the user, an initial filled frame is generated according to a set scale factor, and a contour response map of the filled frame is generated. With the target point as the center point, when the center point slides within a certain range, the window slides along with the center point and scales. According to whether the target point set by the user is within the window, the generated windows are screened, and finally the windows are scored and sorted by the contour density, and the optimal target tracking frame is selected from them.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method for generating an initial tracking frame of an unmanned aerial vehicle target based on computer vision points. Background technique [0002] Object tracking is an important technology in the field of computer vision, and has important applications in military, medical, monitoring and human-computer interaction. It integrates the comprehensive application technology of many different technologies such as image processing, pattern recognition, artificial intelligence and automatic control, and is widely used in various fields. For object tracking, there are many tracking algorithms, most of which use the method of tracking frame to track. [0003] In the process of tracking the target by the tracking frame, the tracking frame needs to be updated in every frame. And the initial tracking box is often used as a matching template in the algorithm, so the initializati...
