A method of calibrating a CCD camera comprising those sequential processes comprises steps of shifting a spot light source held by a positioning device, in front of a fixed CCD camera between two remote points on a visual line in order that light beam in the center of the light source can be incident upon predetermined picture element of a solid sensor built in the CCD camera, computing angles between a plurality of visual lines generated by shifting the light source and the optical axis of the CCD camera based on position data related to the positioning device, and calibrating the corresponding relationship between the angle of light beam incident upon the CCD camera and the predetermined picture elements built in the solid sensor.

A self-illuminating measurable-point member includes; a light source, a fine through-hole which permits light from the light source to permeate therethrough, and a diffusible member which diffuses light permeating the fine through-hole. Light from the light source is condensed via the fine through-hole and diffused via the diffusible member.
