AI Technical Summary
Technical Problem
When existing infrared touch screens recognize two or more touch points, it is difficult to quickly and accurately locate, resulting in an increase in touch response delay.
Method used
By selecting the scanning direction with more touch areas from multiple scanning directions as the target direction, the candidate touch point area is calculated and associated with the touch areas in all scanning directions, the candidate touch point area is recommended based on the number of associated touch areas, so as to quickly remove the fake point area.
Benefits of technology
The calculation of a large amount of false point information is reduced, the response speed of the touch screen is improved, and the rapid and accurate recognition of multi-touch is ensured.

Abstract
The present application provides a touch positioning method, device, equipment and storage medium. The method includes: determining at least two target directions according to the number of first touch areas in each scanning direction among multiple scanning directions; obtaining at least one candidate touch point area according to the first touch areas of at least two target directions; determining the target touch point area according to the number of second touch areas associated with each candidate touch point area; the second touch area is the touch area in the first touch area of each scanning direction that has an overlapping part with the candidate touch point area; locating the touch point according to the target touch point area and the first touch area of each scanning direction. In the embodiment of the present application, in the candidate touch point area located in the target direction selected from multiple scanning directions, the candidate touch point area is recommended based on the number of associated touch areas, and then the false point area is quickly removed, thereby improving the response speed of the touch screen.
