Abstract: This application provides a point cloud data sorting circuit, method. The point cloud data sorting circuit includes a sorting module, which contains a row caching unit and a row sorting unit. The row caching unit is configured to obtain and cache original point cloud data to be sorted. The original point cloud data is obtained by scanning the field of view with the LiDAR. Between two rows of original point cloud data obtained in one second scanning period, there are N rows of other original point cloud data obtained in another second scanning period. The row sorting unit is configured to perform coordinate transformation on the original point cloud data to obtain target point cloud data sorted according to pitch angles. This allows the sorting of original point cloud data to be achieved using independent hardware, improving the sorting speed of the original point cloud data.
