Abstract:
A method of calibrating an RGB-D device having an RGB-D camera and a displacement sensor includes: providing a calibration target, the calibration target including a plurality of visual markers shown in a surface of the calibration target, wherein the plurality of visual markers have known locations on the calibration target; positioning the calibration target within a field of view of the RGB-D device such that the RGB-D camera and displacement sensor capture data corresponding to the calibration target; moving the calibration target a known distance in relation to a location of the RGB-D device; receiving output data from the RGB-D device including data from the RGB-D camera and displacement sensor; aligning data from the RGB-D camera and data from the displacement sensor; calibrating a relative configuration of the RGB-D device based on aligned data output from the RGB-D device and known position information of the calibration target.
