  • Publication number: 20210254968
    Abstract: The disclosure provides an improvement to digital fringe projection techniques in which the optimal focal length settings are automatically determined for reconstructing a 3D profile. In a pre-calibration phase, geometric parameters of the system are calibrated using a few discrete focal length settings. These discretely calibrated geometric parameters are fitted onto a continuous function model. In a 3D autofocusing phase, a set of optimal focal length settings for a scene are determined using a 2D autofocusing technique. Calibrated geometric parameters for each optimal focal length setting are automatically calculated using the continuous geometric parameter model. Finally, a 3D profile of objects in the scene is reconstructed using the calibrated geometric parameters for each optimal focal length setting.
