A gesture detection method and system

Abstract

A gesture detection method and system, wherein the method includes the following steps of detecting a reflected light spot on a reflective surface, and obtaining a gesture command corresponding to the moving track of the light spot according to the moving track of the reflected light spot after detecting the reflected light spot on the reflecting surface, The reflection light spot is formed by reflection of light emitted by a light source provided on the signaling device on the reflection surface, and a preset step corresponding to the gesture instruction is executed. Different from the prior art, the above-mentioned technical solution enables the camera to detect the gestures of the user operating on the known plane content by introducing reflected light spots, and only when the user approaches the plane for writing and drawing, it is judged as a valid command, which is better. It greatly improves the recognition efficiency and accuracy in the field of gesture judgment.

Description

technical field [0001] The invention relates to the field of optical analysis and design, in particular to a method and system for gesture detection through optical signals. Background technique [0002] In the existing field of video shooting and interaction, combined with the development of communication technology, the captured pictures can be directly shared, but there is a lack of means to interact with the recipients of the shared pictures through optical information. Sending signals, such as infrared light, etc., to obtain the optical signal of the signal device through the camera, can complete the analysis of the relative movement of the handheld signal device and the corresponding instructions based on the optical signal. Contents of the invention [0003] Therefore, it is necessary to provide a solution capable of optical gesture command control. [0004] In order to achieve the above object, the inventor provides a gesture detection method, which includes the f...
