A calibration technique for integral photography(IP) based 3D display that uses a commercial projector and digitally designed holographic optical element (DDHOE) as lens array is reported. This is an automated method that compensates for both lens distortion and DDHOE-projector alignment errors which shows huge improvement in reconstruction quality. This method requires less number of input images for calibration compared to existing ones.
