Beschreibung
Zusammenfassung:	The utility model provides a projector image distortion calibration system capable of automatically, conveniently and accurately calibrating the image distortion caused by the excursion of the projector position and a projector using the calibration system. The projector image distortion calibration system comprises an optical ladder calibration device, a space three-axis positioning device detecting the position of the projector relative to the space three-axis, an adjusting device adjusting the position and the angle of the optical ladder calibration device and a control unit sending shift control instruction to the adjusting device according to the position of the projector relative to the space three-axis. The projector image distortion calibration system provided by the utility model can adjust automatically without need for labor force participation and is very convenient, when the projector is shifted; and the projector image distortion calibration system can eliminate the projection image distortion c
