Latest Patents

The supplied information identifies one patent associated with Voorhaar: “Methods, apparatuses and computer programs for determining and using extrinsic calibration of one or more cameras.” The invention describes methods and systems for estimating the transformations between camera coordinate systems and a reference coordinate system. It uses images of co-planar markers to estimate camera and reference-plane poses, then iteratively adjusts marker positions and plane poses to reduce reprojection error. The approach also supports using information about the reference plane’s pose after calibration. Voorhaar is associated with 1 patent in the information provided.
