Abstract

In industrial vision metrology, off-the shelf cameras with known or unknown interior orientation parameters are widely employed. CCD which has long been used as an imaging sensor is now gradually replaced by CMOS. But the authors have often experienced the deterioration of measurement with a CMOS camera, the reason of which is unclear. This paper discusses experiments on precision comparison between the two types of cameras with almost the same conditions. The results show that the measurement precision with a CMOS camera is lower than that with a CCD camera by 5-10% in RMS object space coordinates. This paper discusses the experiment and analysis from viewpoint of respective factors.
