bitmap representation of a point cloud.
I have xyz surface data of an object which I'd like to display on the screen in a similar way as I would be able to in e.g. CloudCompare or MeshLab. My thought was to generate a bitmap using some pre-defined viewpoint.
I've loaded my xyz/pcd into a 3 channel 32 bit float Mat.
Does anyone know of a straightforward way to do this with opencv. I do not have viz.
you could convert/normalize your z-plane to uchar, and use some heatmap
(assuming, you have a "dense" cloud, like exactly 1 z-value for each (x,y))
Thank you @berak. Not quite what I had in mind but maybe useful nonetheless. I guess what I want is closer to PCL land.
