Title:
CALIBRATION INDEX DETERMINATION DEVICE, CALIBRATION DEVICE, CALIBRATION PERFORMANCE EVALUATION DEVICE, SYSTEM, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2010/050412
Kind Code:
A1
Abstract:
Disclosed is a system to determine whether calibration indices are appropriate for each camera when calibrating large quantities of cameras, in which there is great variation in individual differences in image blurring characteristics. The present invention takes an image of a calibration index and calculates the calibration precision that can be expected in calibration from the calibration index image that has been taken. If the calibration precision that can be expected is not optimal for each camera, the density of lines or shapes that constitute the calibration index is changed until the optimum calibration index for each camera is found.
