PROBLEM TO BE SOLVED: To calibrate a camera constant (camera parameter) at a low cost, as to a three-dimensional image measuring camera. SOLUTION: Reference points as a large number of subjects on vertical reference faces 6a-6f with a step difference in a reference plate 6 erected along a long water vessel 1 are photographed by a model ship tugging carriage 3 traveling on rails 2 along a long side of the long water vessel 1, by a three-dimensional image measuring camera set 5 comprising the two cameras 5a, 5b mounted on the carriage 3 to be laterally directed, and a photographed data obtained therein is analyzed to calibrate the camera constant of the camera set 5.
