Paper Abstract

Traditional methods for calibrating structured light 3D imaging systems often suffer from various sources of error. By enabling our projector to both project images as well as capture them using the same optical path, we turn our DMD based projector into a dual-purpose projector and single-pixel camera (SPC). A coarse-to-fine SPC scanning technique based on coded apertures was developed to detect calibration target points with sub-pixel accuracy. Our new calibration approach shows improved depth measurement accuracy when used in structured light 3D imaging by reducing cumulative errors caused by multiple imaging paths.
