摘要
采用MPEG-4压缩算法、DSP技术和现代电子技术,研制了汽车运行状况图像监测系统。在总体设计方案的基础上,基于DSP芯片ADSP-BF533设计了系统硬件,并采用C语言与汇编语言进行混合编程,开发了系统软件。为提高系统可靠性和稳定性,从软、硬件两方面采取了抗干扰措施。本文所研制的汽车运行状况图像监测系统具有对大量视频图像数据的存储、压缩和回放等功能,能够实现对汽车运行状况图像实时记录。
An image monitoring system for vehicle＇s movement is developed with the compression algorithm of moving Picture Experts Group 4（MPEG-4）,digital signal processor（DSP） technology and modern electronic technology in this paper. Hardware and software are designed and some improvement is made in the circuits to decrease power consumption. Anti-jamming measures are taken in the hardware and the software to improve the reliability and stability of the system. This system has the functions of realtime recording, image compression, image replaying and auto alarm.
