2020-04-09 12:54:04 -0500 | marked best answer | Extract a Volume of points from a PointCloud2 message Hi all, I'm trying to achieve something simple, yet I can't seem to find a way to do this. I have a PointCloud2 (as a .pcd file) and a bounding box defined in the same frame as the PointCloud2. I want to extract all the points that lie inside that bounding box and save them as a new .pcd file with the centroid of the box set as the origin of that point cloud. A sample bounding box looks like this: So I have the position (which I want to be the origin of the new PointCloud), the size of the box, and also the orientation as a quaternion. How can I do this? Any pointers to PCL tutorials would be helpful as well. Thank you! |
