基于CMOS数字摄像头检测路径的智能小车设计

Design of Auto Route Identified Vehicle Model Based on CMOS

以Freescale公司的MC9S12DG128作为系统的核心控制处理器,通过CMOS数字摄像头获取前方赛道信息,采用二值化法提取赛道黑线,通过采用特殊的算法来判断赛道的大致变化趋势,从而实现小车提前转向,并根据路况的不同而为小车分配以不同的速度。实验结果表明,小车能够稳定地自动寻线。

Freescale MC9S12DG128 processor was used on an Auto Route Identified Vehicle Model. The vehicle model obtains the track image through a CMOS digital camera. It uses binarization method to get black line. Smart car analyzes the road conditions ahead through a specific algorithm so that it can easily adjust its velocity according to different conditions. The experimental results show that the method was reasonable.
