Latest Patents

One of his latest patents is a camera calibrating apparatus and method. This innovative apparatus utilizes a calibration target in conjunction with a laser source that generates a laser beam. The laser beam defines a calibration plane that intersects the camera's field of view, establishing an object imaging area. The calibration target features a frame that defines a coplanar arrangement of more than five reference points, each with known position coordinates within an object reference system. This arrangement is designed to be parallel to the calibration plane, allowing for precise camera calibration. The target also includes light reflecting members that extend into the object imaging area, enabling the camera to capture images of illuminated portions.

Another significant patent is a system and method for monitoring the quality of log cutting. This method employs optical measurement techniques to assess the characteristics of half-squared or full-squared cants produced during the cutting process. By measuring the profile of the log surface at various cross-sections, the system generates data that helps estimate log raw profile characteristics. This information is crucial for optimizing cutting quality and ensuring the recovery of high-value wood pieces.
