Downsample PointCloud
Is there any option to downsample point cloud using OpenCV? PCL has a downsampling filter but it uses PointXYZ type while OpenCV uses Mat type. I have another issue do I need to calculate normal and save the file before using this code; https://docs.opencv.org/3.0-beta/modu... ?
can you be a bit more concise, what "downsampling" means exactly here ?
would a plain kmeans clustering already do the trick ?
did you try to convert the Mat data to a PCL point cloud, and use their tooling ?
what is your data ? is it a "dense 2d" cloud (e.g. from stereo disparity) ?
