Abstract:
The present disclosure discloses a container positioning method and apparatus based on multi-line laser data fusion, the method comprising: acquiring point cloud data of at least two multi-line laser radars, and performing point cloud data fusion according to a coordinate system relationship between the at least two laser radars; performing clustering of scanning lines according to the fused point cloud data, and acquiring an edge point of a top surface or a side surface of a target container according to the clustered scanning lines; acquiring a contour of the top surface or the side surface of the target container according to the edge point of the top surface or the side surface of the target container to determine a central point and a heading angle of the target container so as to determine a position of the target container. The container positioning method and apparatus based on multi-line laser data fusion provided in the present disclosure acquire an edge point of a top surface or a side surface of a target container after point cloud data is fused via point cloud data of a multi-line laser radar, so as to accurately acquire the position of the target container.
