Python kinect point cloud

The positive Y axis points up, the positive Z axis points where the Kinect is pointing, and the positive X axis is to the left. One unit in this coordinate system is equal to one meter. Alignment A naive way of making a point cloud might directly overlap the depth and color images, so that depth pixel (x,y) goes with image pixel (x,y). The kinect is an amazing and intelligent piece of hardware. It has a RGB camera, an IR laser projector, an IR CMOS sensor, a servo to adjust the tilt of the device and a microphone array. The RGB camera is like any other camera such as a webcam but it is the depth sensor that the Kinect is known for as it...

We present a novel appearance-based approach for pose estimation of a human hand using the point clouds provided by the low-cost Microsoft Kinect sensor. Both the free-hand case, in which the hand is isolated from the surrounding environment, and the hand-object case, in which the different types of interactions are classified, have been considered. The hand-object case is clearly the most ...

Abstract : In recent years, the concept of 3D point cloud, which is a new approach on this subject, has entered the literature. This concept, which is based on the representation of objects as 3D point for processing, analysis or promotion operations on computer, is preferred with its flexible structure, simplicity, strong representation ability and easy availability.
