Assoc. Prof. Xiaobo Chen

Project Description and Objectives

As industries such as shipbuilding, aerospace, and aviation increasingly demand precision manufacturing, the design and production of complex tube systems have become critical areas for technological advancement. Traditional tube measurement techniques can no longer meet the growing need for high precision, efficiency, and adaptability. This project aims to develop advanced optical measurement methods for complex tube geometries based on the technologies of multi-stereo vision, system calibration, 3D reconstruction, image processing, and data evaluation. An optical measurement system for complex tubes will be developed and validated through practical applications. The ultimate goal of this project is to improve the accuracy of dimensional evaluations during the manufacturing process, leading to enhanced precision, higher quality, and greater efficiency in the production of tube components.
