Abstract
An optical displacement sensor takes in a plurality of images of a target object by projecting a slit beam of light and using a two-dimensional image taking element by changing the image taking conditions each time. Parameters defining these conditions affecting the brightness of the obtained image are varied. From each of these images including an image of a portion of the sectional contour line of the target object, a segmented image satisfying a specified maximum brightness condition is extracted and a synthesized image is generated by gathering such segmented images. The target object is inspected from such synthesized image.
