Abstract
Structured light system calibration has been widely studied over the decades, and a variety of calibration approaches have been proposed. Among these methods, the flexible method using flat checkerboard is widely adopted. However, there is a lack of studies on selecting the optimal checker size for high accuracy calibration, whilst it is vital to understanding this factor. This paper presents a systematic study on how the checker size affects the calibration accuracy for a structured light system, and provides a general guideline to select the optimal size. For this initial study, 7 different checker sizes are selected, and experiments demonstrated that the system achieved the best calibration accuracy within a certain range of checker size.
