AbrégéA method for calibrating a computer vision system using a three-dimensional reference object that has a prescribed size and a shape that is not symmetrical as seen from any direction. The method includes: a step for using three-dimensional shape data for the three-dimensional reference object and three-dimensional measurement data obtained by means of three-dimensional measurement to calculate the position and posture of the three-dimensional reference object on a measurement unit coordinate system that has been defined relative to a three-dimensional measurement unit; and a step for calculating a reference/measurement unit transformation matrix that represents the coordinate transformation between the measurement unit coordinate system and a reference coordinate system that is defined by the three-dimensional reference object.
