快速公交专用车道上非公交车辆抓拍系统

摘要

非公交车侵占专用公交车道违章行为频繁出现,严重影响交通效率.通过车载摄像头采集图像,以TMS320DM6437为核心处理器,使用C代码优化及混合编程、存储空间优化等方法,对车道线和车辆进行检测与识别,实现对专用车道内非公交车辆抓拍.实验结果显示,该算法正确率约为83％,平均处理速度为22.5帧/s,对白天多种环境能满足实时准确的要求.%Bus rapid transit road occupied by non-bus largely hinder the efficiency of the transportation system. Two cameras are placed in front of the bus to get videos. These videos are processed on DSP TMS320DM6437 by optimizing C code, storage space and hybrid programming. Therefore, road detecting and tracking is achieved by catching images of non-bus traveling on bus rapid transit road. The accuracy rate is 83%, average processing speed is 22.5 frame/s. The system meets the requirement for real-time and accuracy in complex environments of daytime.
