Hi there!
I am working with LiDAR point cloud data and would like to select some points of my point cloud which are located within a region of interest (ROI).
I know that there are the functions findPointsInROI and select, and I used them before for "simple" point clouds (i.e. with only one frame).
However, now I have a more "complex" point cloud, i.e. one where I have put several frames (60 frames) into the same point cloud, see below:
If I try to use the same functions as I did with the "simple" point cloud for this point cloud, they are not working:
roi = [xlimits, ylimits, zlimits];%Find indices of the points that lie within the cuboid ROI
indices = findPointsInROI(ptCloud,roi);%put points of interest from original pt Cloud into new pt Cloud
ptCloudB = select(ptCloud,indices);
It is not that there is an error message, but the "indices" vector I get does not make any sense (i.e. it does not contain the number of the points which are within the ROI) and the resulting, selected point cloud "ptCloudB" only contains 1 (instead of 60) frames.
Is there any solution to make those functions work?
Thanks!
