POSITION MEASURING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a position measuring system which can measure the position and angle of a target easily and with high precision. SOLUTION: The position measuring system includes: a camera 20 which photographs a first standard marker consisting of three standard markers on a plane which are arranged on a target 10 and of which the mutual positional relationship is specified and a second standard marker which is one standard marker spaced apart from the plane by a predetermined distance and of which the positional relationship with respect to the first standard marker is specified; and a calculation section 30 which discriminates between the image of the first standard marker and the image of the second standard marker on the basis of the positional relationship between four marker images photographed by the camera 20 and calculates the three-dimensional position and triaxial angle of the target 10 on the basis of the positional relationship between the discriminated marker image of the first standard marker and the maker image of the second standard marker.
