WebThe two point clouds overlap in some areas (and not at all in other areas), therefore the merged point cloud likely has an uneven distribution of points. Through the merging operation we get to keep all structure from the input but the even distribution that was just there on the coarse point cloud is gone. WebThe advantages of ICP are high accuracy-matching results, robust with different initialization, and so on. However, it consumes a lot of computing resources. To improve ICP performance on Jetson, NVIDIA released a CUDA-based ICP that can replace the original version of ICP in the Point Cloud Library (PCL).
