THREE DIMENSIONAL POSITION MEASUREMENT SYSTEM, THREE DIMENSIONAL POSITION MEASUREMENT DEVICE, AND THREE DIMENSIONAL POSITION MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To perform stable distance measurement regardless of a direction of a pattern of a target.;SOLUTION: The three dimensional position measurement system comprises a camera and a three dimensional position measurement device. The camera is attached to an object which rotates with movement of a moving body. The three dimensional position measurement device includes a storage part and a three dimensional position measurement part. The storage part stores images photographed by the camera in association with time when each of the multiple images is photographed and a rotation position of the camera at the time. The three dimensional position measurement part selects, among the multiple images, at least two images of rotation positions of the camera giving base line directions different from a direction of a pattern, relative to the pattern of a target, and measures a three dimensional position of the target.;COPYRIGHT: (C)2012,JPO&INPIT
