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.

A workpiece holder is configured to hold a workpiece and is utilized in a metrology system which includes a sensing configuration for obtaining 3-dimensional surface data for the workpiece. The workpiece holder includes at least three reference features (e.g., spherical reference features extending from sides) that are configured to be sensed by the sensing configuration when the workpiece holder is in different orientations (e.g., as rotated 180 degrees between first and second orientations for presenting front and back sides of the workpiece towards the sensing configuration). A determination of 3-dimensional positions of the reference features for each orientation enables a combining (e.g., in a common coordinate system) of 3-dimensional surface data that is acquired for the workpiece in each orientation. Interchangeable workpiece holding portions may be provided that fit within the workpiece holder for holding workpieces with different characteristics (e.g., having different sizes and/or shapes).
