Abstract
A three-dimensional geometry measurement apparatus including a virtual coordinate identification part that identifies coordinates of a virtual captured pixel corresponding to a feature point in an image plane of a capturing device by virtually projecting the feature point on a reference instrument onto the image plane: correction part that generates correction information for correcting coordinates of the measurement-target captured pixel included in a measurement-target captured image; and a geometry identification part that corrects coordinates of a plurality of the measurement-target captured pixels included in the measurement-target captured image generated by capturing an object to be measured with the capturing device on the basis of geometric property information and the correction information, and identifies a geometry of the object to be measured on the basis of measurement three-dimensional coordinates to be calculated based on the coordinates of the measurement-target captured pixels.
