基于双DSP结构的动态手势红外遥控系统
A dual DSP-based infrared telecontrol system on gesture interaction
摘要
Abstract
In order to realize an infrared telecontrol system on user′s gesture interaction, a dual DSP-based system is designed. Due to the complexity of image algorithm on gesture recognition, a line-type image processing mode is used in the system and realized by using a dual-DSP processing platform which based on dual port RAM communication. The first stage of the processing mode is responsible for the real-time data acquisition and image preprocessing while the second stage combined with gesture image algorithm of frame difference and self-learning infrared telecontrol module is responsible for action recognition and telecontrol. Resources are efficiently allocated by Dual DSP structure so that waiting time needed by single DSP is saved and Image processing tasks are processed synchronously. Experimental results show that the shortest recognition time of system is 1.5 second as well as action recognition accuracy reaches 93.75%. The system has good stability and maneuverability.关键词
