Road measurement method based on image processing and related equipment
The invention provides a road measurement method based on image processing and related equipment. The method comprises the following steps: obtaining road images comprising road marking lines based on a preset sampling period, wherein adjacent road images comprise an overlapping region with a preset size; line pixel coordinates of the road line in the road image under a camera coordinate system are extracted; converting the marking pixel coordinates into marking world coordinates under a world coordinate system based on internal matrix parameters and external matrix parameters of the camera coordinate system; converting all the marking world coordinates into target marking coordinates in the same world coordinate system based on the overlapping region; and fusing the target marking coordinates to obtain a road measurement curve.
本公开提供一种基于图像处理的道路测量方法及相关设备。该方法包括：基于预设采样周期获取包括道路标线的道路图像，相邻的所述道路图像包括预设大小的重叠区域；提取所述道路图像中所述道路标线在相机坐标系下的标线像素坐标；基于所述相机坐标系的内部矩阵参数和外部矩阵参数将所述标线像素坐标转换为世界坐标系下的标线世界坐标；基于所述重叠区域将所有所述标线世界坐标转换为同一世界坐标系下的目标标线坐标；对所述目标标线坐标进行融合得到道路测量曲线。
