Method, device, device, and computer-readable storage medium for coordinate anti-shake on screen

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 a touch point, on a screen; processing the image to obtain touch data, wherein the touch data comprises a touch coordinate; calculating a distance between the touch coordinate in the current frame of image and the touch coordinate in a recorded frame of image; comparing the distance with a preset threshold value; if the distance is greater than the preset threshold value, outputting the touch coordinate of the touch point in the current frame of image as a practical coordinate of the touch point in the current frame of image; and if the distance is smaller than the preset threshold value, outputting the touch coordinate of the touch point in the recorded frame of image as the practical coordinate of the touch point of the current frame of image, so as to carry out anti-shake processing. According to the method, anti-shake processing of coordinates can be realized through simple numerical 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 anti-shaking of coordinates on a screen. Background technique [0002] In order for more people to see the content of the demonstration at a longer distance, the files to be displayed are generally converted into optical signals and then projected onto the screen. In the general presentation process, there needs to be an interactive function between the demonstration content and the presenter. For this reason, the method of laser interaction and the method of human-computer interaction are gradually emerging. [0003] The image to be displayed is converted into an optical signal through DLP or a projector and projected onto the display screen to form an enlarged projection image. One way is to touch the screen at close range, for example, the laser emitted by the digital pen forms a to...

Problems solved by technology

[0004] However, in the existing short-distance touch control, unstable clicks may occur on the touch surface (i.e., the screen surface) due to hand shaking and other reasons, resulting in insensitivity of touch control and affecting the accuracy of touch control.
