Abstract: A new method to calibrate the axes of the turntable was presented based on the measurement data in the structured light measurement system. Two balls were mounted on the turntable by a given mode. Let the two balls circle around the swing axis and measure the two balls at different angles. Get each ball’s data and calculate its center. Each ball’s centers define a circle. The two circle’s center defines the swing axis. The rolling axis at the origin position can be decided in the same way. Then the rolling axis at any position can be calculated easily. So the MultiView can be integrated automatically. The experiments show that this method is simple,efficient and can be used in other measuring system with a turntable.
