Embodiment Construction

[0040] The present invention aims to propose a method based on computer vision to generate the initial tracking frame of the UAV target, to solve the problem that the traditional technology adopts the method of artificially setting the tracking frame, which may cause interference or useful information in the initial frame containing too much useless background information Insufficient problems that affect accuracy.

[0041] Its core idea is: after the user manually selects the target point, an initial filled frame is generated according to the 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 tra...

Abstract

The invention relates to the technical field of computer vision, discloses a method for dot generation of an unmanned aerial vehicle target initial tracking box based on computer vision and solves the problems that an initial frame contains excessive useless background information and causes interference in a manual tracking frame setting mode in traditional technology, or useful information is insufficient, and accuracy is affected. After a user manually selects a target point, an initial filling box is generated according to set scale factors, and a contour response diagram of the filling box is generated. The target point serves as a center point, windows slide along with the center point sliding within a certain range, and scale zooming is performed. The generated windows are screened according to the fact whether the target point set by the user is within the window or not, finally, the windows are marked and sequenced according to contour density, and the optimal target tracking box is selected from the windows.

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...
