A control device includes a processing unit for processing a first image captured by a first camera and a second image captured by a second camera. The processing unit performs control using block matching. A first determination value on a block matching score and a second determination value greater than the first determination value are determined in advance. The processing unit generates a first distance image using the first determination value and a second distance image using the second determination value. The processing unit adopts distance information for a pixel contained in the first distance image for a region corresponding to the contour of a workpiece and distance information for a pixel contained in the second distance image for a region other than the region corresponding to the contour to generate a synthesized distance image.
