CALIBRATION REFERENCE POINT ACQUISITION SYSTEM AND CALIBRATION REFERENCE POINT ACQUISITION METHOD

摘要

To improve acquisition accuracy of a calibration reference point.SOLUTION: A calibration reference point acquisition system according to an aspect of the disclosed technology is a calibration reference point acquisition system for acquiring a calibration reference point for calibrating geometric distortion of an imaging device, the calibration reference point acquisition system including: pattern light display means for displaying pattern light to be imaged by the imaging device; relative posture variable means for varying a relative posture between the imaging device and the calibration reference point acquisition system; and processing means for calculating the calibration reference point on the basis of an image of the pattern light imaged by the imaging device while varying the posture. The pattern light display means displays the pattern light by adjusting an amount of light forming the pattern light for each region in a multi-stage manner.SELECTED DRAWING: Figure 4
