| description | PROBLEM TO BE SOLVED: To provide means for measuring a relative position to an object with high accuracy from an operation body which performs at least one of a change in direction or movement.SOLUTION: Coordinate values by which positions of respective points to be measured are represented by a moving body coordinate system are acquired by a laser distance sensor installed in a moving body 3. An area including an object 5 is picked up with an imaging apparatus installed in the moving body 3 to generate an image. In the image, a position of an index mark attached to the object 5 is specified, and a direction of the object 5 is specified in imaging on the basis of the position. According to a relative direction and positions x, y of the moving body 3 in the imaging to the direction and the positions of the moving body 3 in distance measurement, the coordinate values of the respective points to be measured are converted from coordinate values of the moving body coordinate system in the distance measurement into coordinate values of the moving body coordinate system in the imaging. Coordinate values after the conversion corresponding to the position of the index mark in the image are specified, and a distance from the moving body 3 to the object 5 in the imaging is calculated on the basis of the coordinate values. |
