基于多模型结合优化的非结构化道路检测算法
Unstructured road-detection algorithm based on multiple models and optimization
摘要
Abstract
Unstructured road-detection has been a difficulty in the road-detection algorithms. An unstructured road-detection approach based on color Gaussian mixture model and parabolic model was presented. First we took the full-resolution color image and produced a low-resolution color image by a combination of averaging filtering and sub-sampling, and had illumination compensation. Then we formulated Gaussian mixture model based on K-means algorithm, which was optimized clustering center for the road area and the other areas. Next we solved these parameters of right and left road parabolic models by the least square method. Lastly, we fitted the boundary of the road and achieved the extraction of it. The experimental results show that this approach has robustness against uneven illumination, shadows and reliability improving the processing speed.关键词
