Abstract:
A method of inputting three-dimensional data of an object, the method comprising:a step of irradiating a detection light beam toward the object; a step of sensing images of a object at a first position and a second position that is apart from the first position; a first calculation step of detecting reception angles of the detection light beam reflected by the object at the first and the second positions in accordance with the obtained image data, and calculating the position information of a predetermined part of the object in accordance with the detected first and second reception angles and the distance between the first position and the second position; a second calculation step of detecting the irradiation angle and the reception angle at the first position in accordance with the irradiation angle data of the detection light beam and the image data of the first position, and calculating the position information of a predetermined part of the object in accordance with the detected irradiation angle and the reception angle; and a step of obtaining the position information of a predetermined part of the object by one of the first and the second calculation steps.
