Abstract

PURPOSE: To measure a three-dimensional position with high accuracy irrelevantly to the distortion of a lens system by using a regular pattern and determining the correspondence relation between the position of an optional point in an object space determined by a TV camera and the position on its picked-up image.
CONSTITUTION: A calibration plate PLT on which the regular pattern is drawn is placed on a Z0 axis so that it can shift in position, and its pattern edge is detected to project an X0Y0 coordinate system on an image coordinate system. Consequently, the spatial coordinate values of one point on the pattern corresponding to one point A on the image are calculated. Then the pattern is picked up by the TV camera every time the calibration plate PLT is placed at a different position on the Z0 axis, and then the object spatial coordinate values of each calibration plate position corresponding to specific picture elements are calculated. This three-dimensional position measuring method is employed to obtain a sight line equation.
