Title: Ji Fan and Real-Time Crystal Measurement in Glass Crystallizers.
Introduction
Ji Fan is an inventor associated with Dalian University of Technology in Dalian, China. His patent work addresses real-time measurement of crystal dimensions inside a glass crystallizer, where in-situ imaging and limited space present practical challenges.
Latest Patents
Fan is associated with 1 patent: “Method for Real-Time Detection of Length and Width Size Distribution of Crystal Population in Glass Crystallizer by Binocular Telecentric Cameras.” The invention proposes a calibration pole that can extend into an in-situ environment, such as a reactor or glass tube, and establishes a binocular telecentric stereo-vision imaging model. It also describes a rotating-pole calibration method and calibration-plate design for confined spaces, along with a simplified epipolar rectification method to improve matching between snapshot image pairs.
For measurement, the method reconstructs three-dimensional particle positions through ray intersection using analytical solutions. It then estimates crystal length and width by statistically evaluating Euclidean distances between pairs of feature points. These techniques are intended to support quantitative, real-time analysis of crystal populations within the crystallizer.
