Patent ID: 8384913

Claim:
A measuring method comprising steps of: installing a measuring rod in a predetermined relation with respect to a coordinate system set to a mobile object, transcribing a predetermined position of said measuring rod on a ground surface where said mobile object is set, transcribing a measuring point of an object to be measured as set on said mobile object to the ground surface, measuring a distance on the ground surface between said transcribed predetermined position and said transcribed measuring point, obtaining a relation between said measuring point and said measuring rod on the ground based on a result of distance measurement, obtaining a position on a horizontal coordinate plane in said coordinate system of said measuring point based on the obtained relation and on the relation with the measuring rod with respect to said coordinate system, measuring a vertical distance between said predetermined position and the ground surface and a vertical distance between said measuring point and the ground surface, and measuring three-dimensional position of said measuring point in said coordinate system.
