Problems solved by technology

[0004] However, in the existing long-distance laser remote control interaction, with the increase of the distance between the laser remote control and the screen, the slight shaking of the hand will cause the touch point to shake violently on the screen, thus affecting the accuracy of touch control

Abstract

The invention discloses a method, device and equipment for preventing coordinates on screens from shake and a computer readable storage medium. The method comprises the following steps of: obtaining an image, comprising touch points, on a screen; processing the image to obtain touch data, wherein the touch data comprises a touch coordinate; calculating a distance between a touch coordinate in thecurrent frame of image and an average coordinate of touch coordinates in preset frames of images before the current frame; comparing the distance with a preset threshold value; if the distance is greater than the preset threshold value, outputting the touch coordinate in the current frame of image as a coordinate of the touch point; and if the distance is smaller than the preset threshold value, outputting the average coordinate as the coordinate of the touch point so as to carry out anti-shake processing. According to the method, anti-shake processing of coordinates can be realized through simple numeric comparison, and the calculated amount is small, so that the operation of determining practical coordinates on screens is higher in speed and higher in efficiency.

Description

technical field [0001] The present invention relates to the field of intelligent interaction technology, in particular to a method, device, equipment and computer-readable storage medium for coordinate anti-shake on a screen. Background technique [0002] In order that more people can see the content of the demonstration at a longer distance, generally the files to be displayed are converted into optical signals and then projected onto the screen. In the general demonstration process, there needs to be an interactive function between the demonstration content and the presenter. For this reason, the current method of laser interaction and the method of human-computer interaction are gradually emerging. [0003] Through DLP or projector, the image to be displayed is converted into an optical signal and projected onto the display screen to form an enlarged projection image. The laser remote control emits a laser beam from a long distance to irradiate the touch point on the sc...
