Latest Patents

Shuang 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. It establishes a binocular telecentric stereo-vision imaging model and describes a rotating-pole calibration method and calibration-plate design suited to limited spaces. A simplified telecentric stereo epipolar rectification method supports accurate matching of image pairs captured in situ. The method then reconstructs particles in three dimensions using ray intersection and analytical solutions, and evaluates crystal length and width from Euclidean distances between paired feature points.

Career Highlights
