| 摘 要： | 为实现结构化道路的检测，提出了一种用于道路检测的激光雷达和视觉融合法，通过提取激光雷达在道路边缘的三维点云信息，将其投影到视觉图像上，形成激光点云与图像的映射关系，生成激光雷达似然图。通过改进提取道路的颜色、纹理、水平线等特征的方法，生成相对应的视觉似然图。在贝叶斯框架下将激光雷达和视觉生成的似然图进行融合。在KITTI数据集上测试可知，精度达到94%，准确率达到86%，表明该道路检测法具有较好的道路检测果。

| Abstract: | This paper proposes a method using lidar and vision fusion to achieve structured road detection.The paper extracts the 3D point cloud data from the lidar targeting the edge of the road and projects it onto the visual image to form laser points. The mapping relationship between the laser point cloud and the image is established to generate a lidar likelihood map. The corresponding visual likelihood map is produced by improving the method of extracting features such as color, texture and horizontal lines of the road. Finally,we innovatively fuse the likelihood maps generated from the lidar and visual data within the Bayesian framework. Evaluations on the KITTI dataset show an accuracy of 94% and a success rate of 86%, proving the effectiveness of the proposed road detection method. |
