摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional measurement method using a digital camera.;SOLUTION: The three-dimensional measurement method using a digital camera configured to capture a plurality of photographs including a subject in common from first and second imaging points by means of a digital camera C with camera parameters set, calculate parameters for coordinate transformation of coordinates on the set of photographs into a common coordinate system from positions on the photographs of and measured distances between five or more fixed points, measure positions of target points in both photographs in a three-dimensional coordinate system originated at the first imaging point, transform the three-dimensional coordinate system into an objective coordinate system, and measure positions of the target points in the objective coordinate system includes a step of including in the subject a vertical measure 22 with verticality ensured and a measurement index point Px arranged arbitrarily in a different position from the vertical measure 22, and determining the objective coordinate system on the basis of the vertical measure 22 and measurement index point Px imaged in the photographs.;COPYRIGHT: (C)2011,JPO&INPIT
