<P>PROBLEM TO BE SOLVED: To provide an on-vehicle camera posture detection device capable of accurately detecting the posture of a camera. <P>SOLUTION: An on-vehicle camera posture detection device includes: a pre-movement image storage section 20 for storing a pre-movement image of a calibration sheet 200 imaged by a camera 10; a pre-movement camera posture estimation section 24 for estimating the posture of the camera 10 on the basis of the pre-movement image; a post-movement image storage section 22 for storing a post-movement image imaged after moving a vehicle linearly by a prescribed distance; a post-movement camera posture estimation section 26 for estimating the posture of the camera 10 on the basis of the post-movement image; a deviation amount calculation section 32 for calculating a deviation amount of the calibration sheet on the basis of the two estimation results; a camera posture determination section 34 for determining the posture of the camera 10 on the basis of the camera 10 posture estimation value and the deviation amount of the calibration sheet; and a linear movement determination section 46 for determining whether the movement of the vehicle is linear or not. <P>COPYRIGHT: (C)2013,JPO&INPIT |
