Latest Patents

Chengzhang He holds a patent for a "Global registration method based on spherical harmonic transformation (SHT) and iterative optimization." This method introduces two key assumptions: the first is that a minimum percentage of correct matching pairs in an input point cloud is predefined, which serves as a limit on the quantity of outliers. The second assumption involves a preset distance threshold that determines the correct matching pair based on specific scenarios. The algorithm begins with coarse registration to identify multiple search domains, which are then sorted according to an evaluation criterion. A branch and bound method is employed to eliminate incorrect search domains, ultimately leading to a final registration result.
