Latest Patents
Conghan Cao holds a patent for a method that addresses the challenges of personnel interference during volume measurements. The patent, titled "Method for detecting and removing personnel interference while measuring volume of an object," outlines a systematic approach to obtaining an image of an object, removing background information, and converting the image into a binary format. The method includes detecting the object's outline and determining if it extends to the boundary of the field of view. If the outline does not extend to the boundary, the volume is measured directly. If it does, the method employs morphological techniques to remove any extending parts before measuring the volume again. This innovative method not only improves measurement accuracy but also issues warnings based on the measurement conditions.
