Problems solved by technology

[0003] At present, the tracking technology relies on the judgment of the distance to determine the tracking point belonging to a specific trajectory. However, in the actual process, when the distance is too close or because of the problem of the shooting frame rate, it is inevitable to encounter the accuracy rate when solving the tracking problem from the distance judgment. Bottleneck, which manifests itself as a tracking error when a point belonging to another motion track is closer to a point on the previous frame of this motion track
On the other hand, there are some methods to improve accuracy through area matching or contour matching. However, all these methods focus on one aspect to solve the problem of matching accuracy. According to the actual situation, there will be some misjudgments. Wrong choice of matching method, resulting in inaccurate tracking results

Abstract

The invention discloses a method for improving tracking accuracy of a touch system. An area matching method, a contour matching method and a coordinate matching method are combined through weight, the shortcoming of track matching by means of a unilateral evaluation standard is overcome well, and the reference solution is provided for follow-up tracking.

Description

technical field [0001] The invention relates to the technical field of motion tracking, in particular to a method for improving the tracking accuracy of a touch control system. Background technique [0002] With the development of computer technology and digital image processing technology, the application field of computer vision technology has expanded rapidly, and object tracking has become a very active topic in the field of computer vision. The purpose of the automatic tracking control system of the moving target is to use the camera to collect the video image sequence of the target, and analyze the target's motion in real time through the computer to obtain the target's motion parameters, which is used as the main basis to control the camera to always point to the target. [0003] At present, the tracking technology relies on the judgment of the distance to determine the tracking point belonging to a specific trajectory. However, in the actual process, when the distanc...
