How can I convert a 3D point cloud into a 2D top view grid/map?

Hi there, I am writing my thesis about a cleaning robot using a kinect sensor for mapping.

I took a snapshot with the kinect depth camera. Then I got the 3D point cloud and now I want to convert the cloud into a 2D plane/topview grid. Anyone knows how to do that?

I am thankful for any answer!

scatter() ignoring the Z coordinates.

More generally you can scatter3() and set your view() as desired.

Thank you. Do you think it's possible to make a 2D occupancy grid map out of it and how is that done?

HeatMap() if you have the right toolbox. If not then see
