Title:
CALIBRATION DEVICE, CALIBRATION METHOD, AND CALIBRATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/022452
Kind Code:
A1
Abstract:
Provided is a calibration device that acquires an image in which a capture target positioned in front of a vehicle is captured, or that acquires an image in which a capture target positioned behind the vehicle is captured, such image being different from the image acquired when the area in front of the vehicle is captured (S280, S290). At such time, the shape and size of the capture target is known. The calibration device carries out projection conversion of the capture targets captured in an overlapping region of the acquired images, and the calibration device specifies the roll, pitch, and height of the image-capture camera so that the conversion results conform to the shape and size of the capture target (S380). The calibration device also specifies the x coordinate, y coordinate, and yaw of the image-capture camera so that the size of one link angle in a virtual link structure becomes the minimum size (S390).
