CALIBRATION REFERENCE POINT ACQUISITION SYSTEM AND CALIBRATION REFERENCE POINT ACQUISITION METHOD

摘要

Disclosed is a calibration reference point acquisition system for acquiring a calibration reference point to calibrate geometric distortion of an imaging device. The calibration reference point acquisition system includes a pattern light display unit configured to display pattern light to be imaged by the imaging device; a relative orientation change unit configured to change a relative orientation of the imaging device with respect to the pattern light display unit; and a processor configured to calculate a calibration reference point based on the imaged pattern light captured by the imaging device while changing the relative orientation of the imaging device, wherein the pattern light display unit displays the pattern light by adjusting an amount of light in each of regions of the pattern light in multiple stages.
