基于DSP的手势识别电视遥控器设计

由于传统电视机遥控器的按键操作比较机械且缺乏娱乐性,设计了一种以DSP2812为核心的手势识别算法。通过将用户手势运动的信息转换成相应的红外信号,从而实现手势遥控电视机更换频道和调节音量的目的。该系统主要由双端口RAM通信的双DSP并行处理器、CMOS数字摄像头、红外遥控模块、上位机调试软件和以太网通信模块组成。实验测试表明,该系统能够实现用户手势图像的采集、手势动作的识别、红外遥控及以太网通信功能。

Design of Gesture Recognition TV Remote Control Based on DSP

As traditional TV remote control buttons operation is relatively mechanical and lack entertainment,a gesture recognition algorithm based on DSP2812 is designed in the paper, by converting information of user gesture movement into infrared signal, in order to achieve remoting control TV channels and adjusting volume replacement by gesture. The system is mainly composed of dual DSP parallel processors based on dual-port RAM communications, CMOS digital camera, infrared remote control module, PC commissioning software and Ethernet communication module. The experiments shows that the system can achieve the functions of user gesture image acquisition, gesture recognition, infrared remote control and Ethernet communication.
