摘要
针对车道线识别鲁棒性的问题,提出了基于Hough变换的车道线检测方法。为解决Hough变换检测直线速度慢的问题,文中采用了并行加速处理技术,将待检测图片分解成左右两个感兴趣区域分别分配给两个CPU,再将两个CPU并行独立运行的检测结果进行汇总。实验数据表明,车道线检测速度提高了39.1%,车道线检测质量优于传统的串行检测,提高了Hough变换的车道线检测实现效率。
A lane line detecting method based on Hough transformation is proposed to improve the robustness.A parallel accelerated processing technology is adopted to improve the speed of detecting line for Hough transformation. The image to be detected is divided into two interesting regions assigned to two CPUs respectively for processing. Then the two independent detecting results are combined. The experiment results indicate that the detecting speed is increased by 39. 1% with higher quality and efficiency than traditional serial detecting.
