Abstract

PURPOSE: To obtain the position of the inspected body of cylindrical shape and its radius, by measuring the object with the first projector and detector and the second projector and detector, and by performing the measurement through the change in the combination.
CONSTITUTION: The light flux from the first projector 11 radiates the inspected body 6 with the semi-transparent mirror 41, and the light toward the center 0' of the object 6 is reflected at the point T1. When the image is formed on the photo electric plane 10 of the ITV camera being the first detector, the image of T1 is formed at the position apart by b from the reference point R1. Similarly, the point T2 is formed from the second projector 12 to the second ITV camera photo electric plane 102 to obtain the shift b from the reference point R2, and the position is detected with a and b. Next, the point S of the detected body 6 by the projector 11 is formed on the photo electric plane 102, similarly the point S by the projector 12 is formed on the photo electric plane 101, and the radius of the detected body 6 can be obtained from a' and b'.
