Intelligent combination projection system

This paper introduces the design and implementation process of intelligent combination projection system. The system consists of Kinect, computer and projector. There exist two modes in the system: the automatic follow spot mode and human-computer interaction mode. Kinect transmits depth data stream and skeletal frames to computer via USB port. Then the computer processes data and generates the projected image on the computer screen. When the image on computer screen is projected, different colors can be projected on the corresponding parts of the human body in the first mode, or the human body in front of the system can interact with the projected image in the other mode.
