The method relies on a digital camera placed at the location of the audience, and images are obtained in order to observe the deformations caused by the projection angle and surface deformations. Furthermore, we extend this method to combine two or more projectors in order to create a single, overlapped projection area. We demonstrate that this method creates a collaborative effect between the projectors and allows the display of more complex images without increasing the scan rate. ƒL[ƒ[ƒh(˜a•¶5ŒÂ’ö“xA‰p•¶5ŒÂ’ö“x) Laser Graphics, Laser Projection, Camera-Based, Calibration, Projector Array
