A registration algorithm for point clouds obtained by scanning objects on turntable with a stepper-motor is presented.Firstly three or more point clouds were used to calibrate the position of central axis of the rotating platform.So the relationship between the scanner and the rotating platform were defined.Then the rotate matrix was calculated with the angle of the rotating platform to rotate point clouds into the same coordinate system.Only the angle of the rotating platform was needed in this method.The method implemented with C++ language had proved stable,efficient,high degree of automation,good registration performance and high practical value,which could be used in many 3D scanning system such as laser finder system and structure light scanning system.
