PointCloud Using Regular Camera

asked 2015-08-18 12:08:26 -0600

Is it possible to use a webcam (Regular RGB) with Point Cloud Library (PCL) or do I need to use a depth-sensor camera?

I would like to read hand movements from a regular RGB-camera (Nothing in 3D), and I was thinking of using pointcloude. But the question is if I can read RGB data using pointcloude and openni?

  • you can analyze hand movement in plain2d with images from an rgb webcam (no pointcloud needed)

  • if you want to generate 3d pointclouds, you need depth information, either from a special sensor(openni) or from a stereo cam setup (blockmatching) or even from mulltiple images of a single webcam (structure from motion)

Thanks for the answer, is it recommend to use Point Clouds for hand-movemnt recognition or should I focus on openCV? Many has recommend Point Cloud as more adavanced library.

yea pcl is a cool thing.

apart from that, opencv is more a 2d library, while pcl focusses on 3d things.

no idea, which will fare better for your idea, actually, your job to find out ;)
