Design and Implementation of an Around View Image Storing System Based on Car PC

摘要

The automotive electronic systems for effective driving include a navigation reflecting real-time traffic information, a blind spot camera for accident prevention, a black box for recording driving image prior and after accidents, an around view monitoring system enabling all the sides to be seen, etc. The existing around view monitoring system among them was developed based on the embedded system in order to provide real-time information around a car in blind spots and narrow spaces. In this paper, we have implemented an around view monitoring system which enables image storing by combining the strong points of the around view monitoring system and those of the black box. In this system, location information which is not provided by the existing AVM systems of automotive companies is added to the around view monitoring system based on Car PC by way of using a USB GPS receiver with which location information and speed can be detected. This study has implemented an image storing system in which latitude, longitude and speed information are detected by using the RMC sentence summarizing the minimum data of GPS through the GPS receiver, and images from four cameras are input and synthesized and then, saved altogether with location and speed information in the storing device.
