Position coordinate prediction method for gesture control motion, intelligent terminal and medium

Abstract

The present application provides a position coordinate prediction method for gesture-controlled motion, an intelligent terminal and a medium, the method comprising: collecting a motion image of a gesture-controlled motion, and acquiring multiple initial positions of the gesture-controlled motion according to the motion image Coordinates; calculate the speed value and acceleration value corresponding to the multiple initial position coordinates, and determine the motion type of the gesture control motion according to the speed value and acceleration value; determine the gesture control motion according to the motion type The position-time change relationship of the movement; according to the position-time change relationship, the position coordinates of the gesture control movement within the delay time are predicted. The present application predicts the position coordinates within the delay time through the position-time change relationship, and complements the delayed position coordinates, so that the processed position coordinates are synchronized with the position of the gesture movement, ensuring the accuracy of gesture control.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method for predicting position coordinates of motion controlled by gestures, an intelligent terminal and a medium. Background technique [0002] With the development of science and technology, there are more and more ways to control the screen of smart terminals, from physical button control, external mouse and keyboard and other physical device control to remote control, virtual button control, touch screen control, and then to motion gesture control. For motion gesture control, cameras are usually used to track human body movements, and control commands are sent to smart terminals through the tracked human movement behaviors, so as to separate from physical devices such as remote controls, mouse keyboards, etc., while avoiding close touch, a certain range can be achieved. Internal control operations on the smart terminal screen. [0003] Among various huma...

Problems solved by technology

For example, the movement of the cursor is controlled by gestures. After the operator stops the gesture, due to the delay of the gesture image collected by the camera and the delay of processing the gesture image, after the operator stops the gesture, it is still processing and responding to the previous gesture. so that the controlled cursor moves beyond the established target
