    Any point cloud api to use with the webcam?

    I've a webcam and I want to use the video input to get 3d points of an object, for example like this:


    There is any vb code or api that I can use to accomplish the point cloud?

    I don't see how.
    Normally you would use a sensor, not a camera to generate point cloud data, i.e. a LIDAR or other active emissive and receiver based sensor (think Microsoft Kinect, which used an infrared projector and CMOS sensor to detect depth).
    Microsoft provides depth functions as part of the Kinect SDK, and can be used to generate point cloud and merged imagery, as seen at this link, as an example
    A stereo camera can give some low resolution type point cloud type data, as a number of gesture based technologies are based on that, but with a single image camera, there isn't the information needed to determine depth, because you need to see a point from two perspectives and use triangulation to calculate distance.
