Abstract

A kind of testing method of the infrared touch screen algorithm based on MATLAB provided by the present invention, its infrared touch screen is provided with a plurality of infrared emitting tubes, each infrared emitting tube includes a plurality of optical paths, and each optical path is correspondingly provided with a mask value; method comprises : Input the simulated motion track in MATLAB, and obtain the coordinate value of the touch point in the simulated motion track; according to the coordinate value, and at the same time, according to the parameter information of the preset touch object, determine the occlusion area information of the touch object corresponding to the touch point; Blocking area information and the mask value of each light path determine the blocking light path information; record and save the blocking light path information to the light path data of the infrared emission tube corresponding to the blocking light path to form an excitation file; add the excitation file to the infrared touch screen algorithm simulation. Therefore, the present invention is independently performed without depending on the hardware of the infrared touch screen, and the system debugging efficiency is high.

Description

technical field

[0001] The invention relates to the technical field of infrared touch screen algorithm testing, and more specifically, relates to a testing method of an infrared touch screen algorithm based on MATLAB. Background technique

[0002] The infrared touch screen is composed of infrared emitting and receiving sensing elements installed on the outer frame of the touch screen, and an infrared detection network is formed on the surface of the touch screen. Specifically, the circuit board device arranged on the four sides of the infrared touch screen screen has an infrared emitting tube and an infrared receiving tube, and the infrared emitting tube and the infrared receiving tube correspond to form a horizontal and vertical infrared matrix. Any touching object can change the infrared on the contact point. And then converted into contact coordinates, and sent to CPU (Central Processing Unit, central processing unit) to realize the touch screen operation.
