Design and implementation of wireless multimedia sensor network node based on DSP and binocular vision

Abstract

In order to meet the requirement of multimedia information acquisition in wireless sensor network,a new wire-less multimedia sensor node is designed and implemented with the high-performance DSP processor as the core.ZigBee module is used to implement the wireless communication.In virtue of the powerful computing ability and peripheral in-terfaces of DSP processor,the multimedia node owns binocular vision and various sensors such as accelerometer.There-fore,it can attain the real-time perception of environmental information and acquire image/video data.Based on the Zig-Bee protocol,the sensor is able to fulfill short-distance wireless communication and monitoring duty in indoor environ-ment.Experimental results show that the multimedia sensor node designed can accurately obtain and handle the syntheti-cal sensing data in real time.It is suitable for the application of wireless multimedia sensor network.
