Title:
CAMERA ANGLE CALCULATION DEVICE, CAMERA ANGLE CALCULATION METHOD AND CAMERA ANGLE CALCULATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2010/052772
Kind Code:
A1
Abstract:
A marker is arranged in a region where the visual field of a camera (10a) and that of a camera (10d) overlap with each other, a marker is arranged in a region where the visual field of the camera (10a) and that of a camera (10b) overlap with each other, and a marker is arranged vertically below the camera (10b). Furthermore, a marker is arranged in a region where the visual field of the camera (10b) and that of a camera (10c) overlap with each other, a marker is arranged in a region where the visual field of the camera (10c) and that of the camera (10d) overlap with each other, and a marker is arranged vertically below the camera (10d). A calibration device (100) photographs the markers arranged under the above-mentioned conditions by using the cameras (10a-10d), and based on the marker coordinates in the photographed images, camera angle parameters are calculated.
