Abstract
An apparatus () for surface contour imaging of an object has an illumination apparatus energizable to direct one or more illumination patterns () toward a surface position. A sensing apparatus () has at least one lens () and a sensor () that is energizable to obtain one or more images of the surface position corresponding to the illumination patterns (). A calibration target () is detachably coupled to the apparatus () in the surface position, wherein the calibration target () has a set having a plurality of raised features () that are uniformly spaced apart with respect to first and second orthogonal axes that define a first plane and having a uniform height along a height axis that is orthogonal to the first plane. The raised features () further have at least a first slanted surface () that is oblique with respect to the first plane and oblique with respect to the height axis.
