Title: Haibo Niu and Real-Time Crystal Measurement

Introduction

Haibo Niu 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 place can be challenging.

Latest Patents

Niu 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 describes a binocular telecentric stereo-vision system for capturing and analyzing crystals in an in-situ environment.

The method includes a calibration pole designed to extend into a reactor or glass tube, along with a calibration approach suited to limited space. It also proposes a calibration plate design and a simplified telecentric stereo epipolar rectification method to support accurate matching of image pairs. For three-dimensional measurement, the patent uses ray intersection based on analytical solutions to reconstruct particle postures. It then evaluates crystal length and width using Euclidean distances between corresponding feature-point pairs.

Career Highlights

Niu’s patent reflects work at the intersection of imaging, calibration, and quantitative analysis. Its techniques are designed to measure crystal dimensions and distributions without relying solely on observations outside the crystallizer.
