摘要
利用视觉传感器和DSP6300,建立了一种车道偏离预警系统的视觉感知系统。视觉传感器采用标准的TWAIN协议。本文实现了相应的软件系统,开发了基于动态ROI的车道边缘搜索算法,实现了边缘点位置预测和搜索范围限定,保证了算法的抗噪能力和实时性能。运用图像预处理算法更好地提高了车道识别过程的稳健性和精确性。由于搜索带的建立,整个识别过程的计算量大大降低,因此更适合实时要求。
A vision system of Lane Departure Warning System is built up with low cost imaging sensor and DSP6300. The communication between sensor and DSP is based on USB protocol. The data transferring between software and hardware is based on TWAIN protocol. The developed system is independent of conventional imaging card. A road edge searching algorithm is also presented. The algorithm realizes prediction of edge points and constraints of searching boundary., and ensures the performance for real time and noise control.
