Abstract

PURPOSE: To enable thickness of an object to be measured with accuracy, even when there exist round corners and cracks on the edges of the object, by forming a light-radiating line around the center on the top surface of the object by a projecter and photographying the light-radiating line.
CONSTITUTION: The relationship between a projector 3 and a photographying device 4 is set so that a light-radiating line 5' comes to the center of a view line 7' when an object 1 of the standard height of H0 is moving on a conveyor. When the object 1 of H+ΔH is conveyed in this condition, the position of the light-radiating line 5'moves to P0'. At this time, if a distance D1' between P0' and P1 and also a distance D2 between P0' and P2 were able to be sought, it is possible to seek from Equation 1 an amount of displacement ΔH toward base surface of the object being measured. And therefore, by providing a means of calculating the displacement value ΔH on the basis of an output of photographying device 4, it becomes possible to automatically and non-contactly measure thickness of the object, even when there exist round corners and cracks on the edges of the object.
