Abstract: Disclosed is a method for improving the calibration of multiple projector systems in Spatial Augmented Reality systems where multiple projectors are used to project images directly onto objects of interest. The methods and system described herein improve the calibration of multiple projector systems in order to improve the alignment and clarity of projected images by reducing ghosting that can occur with poorly aligned projectors. The system uses a planar photodiode and the projector is used to project a plurality of projection regions, such as scan lines, across the planar photodetector and calculating the position based on weighting measurements by the measured light intensity and projected images in SAR.
