摘　　要：本系统是以微控制器S3C2410为核心。利用摄像头采集图像数据,将图像数据经过USB传输到ARM9开发板的处理器上,在Linux操作系统下对图像进行格式转换。经过最小二乘法和拉格朗日多项式拟合的高精度测距、测速函数进行处理。控制信号通过SPI总线传输到74HC595上,然后通过硬件驱动控制实验小车的减速装置,从而达到防撞车的目的。该系统通过wifi模块将未作处理的图像数据无线传输至上位机。通过人机交互处理其他相应状况。The system is based on microcontrollers S3C2410 core. The camera collected image data, image data through the USB transfer to the ARM9 development board processor under the Linux operating system image format conversion. Precision Ranging of the least squares method and Lagrange polynomial fitting, the tachometer function for processing. Control signal is transmitted via the SPI bus on the 74HC595, so as to achieve the purpose of the crash ear, and then through the hardware drivers to control deceleration devices of the experi mental car. Wireless transmission of image data via wifi module processing first bit machine . Other appropriate conditions by the human- computer interaction.
