Gesture recognition system and method based on ambient light

Abstract

The invention relates to the technical field of gesture recognition, and aims to provide a low-cost and high-accuracy gesture recognition system and method based on ambient light, which can overcome the requirements of similar systems on light sources and have more abundant use scenes. According to the technical scheme, the gesture recognition system comprises a data acquisition terminal, a gesture recognition server and an application terminal; the data acquisition terminal comprises a plurality of photoelectric receivers, a signal amplification module, an analog-to-digital conversion moduleand a signal processing module; the photoelectric receiver is used for capturing optical signal changes generated by gesture actions; the output end of the photoelectric receiver is connected with theinput end of the signal amplification module; the output end of the signal amplification module is connected with the input end of the analog-to-digital conversion module; the output end of the analog-to-digital conversion module is connected with the input end of the signal processing module, data information processed by the signal processing module is transmitted to the gesture recognition server to be recognized, the gesture recognition server outputs recognition information and sends the recognition information to the application end, and the application end displays the recognition information in real time.

Description

technical field [0001] The present invention relates to the technical field of gesture recognition, in particular to a gesture recognition system and method based on ambient light. Background technique [0002] The popularity of smart devices and the continuous innovation of human-computer interaction complement each other. Traditional smart homes or smart buildings usually use IoT technology to network smart devices, and send instructions through smart terminals to interact with them. This traditional interaction method is gradually developing towards a natural interaction method with lower learning costs. Voice assistants such as smart speakers such as Tmall Genie and smart devices such as Siri are common in the market. As one of the natural interaction methods, voice recognition has gradually matured and been widely used. Although there are products such as Kinect and Leap on the market, gesture recognition is still rarely used in daily life. [0003] Common methods fo...

AI Technical Summary

Problems solved by technology

[0005] 1) It is necessary to install additional modulation equipment at the light source, which is inconvenient to install and increases the system cost;

[0006] 2) Due to the need for modulation, the light source type of the system can only be LED, but in fact the current penetration rate of LED is not high;

[0007] 3) The main work of the system is 3D reconstruction. If it is used in gesture recognition scenarios, additional work is still required
