The method involves projecting individual strip patterns onto the projection surface through each projector, recording with a camera, filtering recorded patterns to compensate for background noise, ambient light and/or camera distortions and to determine line intersection points, comparing recorded and know line intersection points to determine distortion correction data and computing warp fields and image warping according to the correction data. The method involves projecting individual strip patterns onto the projection surface through each of the projectors, recording them with a camera, filtering the recorded patterns to compensate for background noise, ambient light and/or camera distortions and to determine line intersection points, determining the largest possible projection surface, comparing the recorded line intersection points with known points in the projected image to determine distortion correction data and computing warp fields and image warping according to the correction data. AN Independent claim is also included for the following: (a) a system for automatic calibration of multi-projector systems. |
