Title: Tingman Yan and Real-Time Crystal Measurement
Introduction
Tingman Yan is an inventor associated with Dalian University of Technology in Dalian, China. His patent work addresses the measurement of crystal populations inside glass crystallizers, where observing particles in an in-situ environment presents practical challenges.
Latest Patents
Yan is named on one patent, titled “Method for Real-Time Detection of Length and Width Size Distribution of Crystal Population in Glass Crystallizer by Binocular Telecentric Cameras.”
The invention describes a method for measuring the length and width distributions of crystals in a glass crystallizer using binocular telecentric cameras. It proposes an extendable calibration pole for use inside a reactor or glass tube, a binocular telecentric stereo-vision imaging model, and a rotating-pole calibration method suited to confined spaces. The patent also presents a calibration-plate design and a simplified telecentric stereo epipolar rectification method to support accurate matching of image pairs captured in situ.
For three-dimensional measurement, the method reconstructs particle positions through ray intersection using analytical solutions. It then evaluates crystal length and width from Euclidean distances between corresponding feature-point pairs. The approach is intended to enable quantitative, real-time analysis of crystal size and posture.
