<P>PROBLEM TO BE SOLVED: To provide an on-vehicle camera posture detection device capable of precisely detecting positions of calibration indexes contained in a calibration sheet. <P>SOLUTION: An on-vehicle camera posture detection device 100 includes: a pre-movement image storage section 20 and others for storing an image of a calibration sheet 200 imaged by a camera 10: and a pre-movement camera posture estimation section 24 and others for estimating the posture of the camera 10 on the basis of these images. The calibration sheet contains large first calibration indexes 220 and small second calibration indexes 210. The pre-movement camera estimation section 24 and others include a calibration index center position detection section 60 for detecting the positions of the first and second calibration indexes 210 and 220. The calibration index center position detection section 60 detects the positions of the second calibration indexes 210, and when cannot detect at least a part of the indexes, detects the positions of the first calibration indexes 220. <P>COPYRIGHT: (C)2013,JPO&INPIT |
