A method for repairing touch system contact track errors

Abstract

The invention discloses a method of repairing touch point locus errors for a touch control system. The method of repairing touch point locus errors for a touch control system includes the main steps: a camera captures the image of a touch point on a screen, and transmits the image to a host; the host receives the image transmitted from the camera, and detects and tracks the image; the host determines whether the touch locus is correct according to the above tracking result, and at the same time, the host transmits the calculating result to the screen; and the screen receives the tracking result transmitted from the host and displays the tracking result. The method of repairing touch point locus errors for a touch control system utilizes the principle that as a finger moves on the screen faster and faster, the motion locus of the finger is more close to the linear system, and the next point is more likely dropped directly at the front of the linear locus, so that the method solves the problem that the finger is hard to track because too long distance between the next frame and the last frame is generated when the finger moves quickly on the screen, and provides a reference solution scheme for the later tracking problem.

Description

technical field [0001] The invention relates to the technical field of track tracking of screen points, in particular to a method for repairing wrong track of touch points in a touch 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, there is no specific solution for similar tracking problems in screen finger detection. Relying on other system prediction methods will cause some additional problem...

Problems solved by technology

[0003] At present, there is no solution for similar tracking problems in screen finger detection. Relying on other system prediction methods will cause some additional problems, such as predicting the prediction point behind the existing movement point, etc., which makes the original solution to the problem The original intention of - making up the distance has a negative impact, making the distance between each other even greater, such as Figure 5 As shown, when the finger moves quickly on the screen, it is difficult to match and track because the distance between the next frame and the previous frame is too large
