The Research Of Vehicle Image Acquisition And Processing System

This article describes the high-definition image format conversion and compression technology, the main research content is high frame rate CCD cameras and analog camera output image data acquisition, and then collected by the digital images and analog images for image format conversion processing andAfter the reunification of the format, the image compression, the final compressed image data stream through the wireless microwave transmission to a remote receiver, save communications bandwidth.The system functions mainly in hardware and software, through which two are described in detail how to achieve the image compression and wireless microwave communication of data transmission.The hardware is the use of FPGA chips on the sample digital image format to unified format and MEGA128 control image compression and decompression chips.System software mainly uses MPEG image compression and decompression technology.This workflow detail by project the image format conversion, MPEG compression algorithms, coding mode, the wireless transmission steps.The eventual realization of ultra-long-distance image transmission function.
