Накратко на български
Методът за 3D измерване на огледални повърхности позволява точно определяне на формата на предмети, които отразяват светлината. Това помага за намаляване на грешките при измерване и подобрява точността на получаните данни за обекта.

Accurate Full-Field 3D Shape Measurement Technique of Specular Surfaces by Phase-to-Depth Deflectometry
This Fellowship not only have studied a novel phase-to-depth deflectometry for measuring full-field 3D shape of specular objects with isolated and/or discontinuous surfaces, but also published 17 high-level journal and conference papers, and developed an instrumentation system. The developed instrumentation system has been tested in the hosting organisation of EPSRC Future Metrology Hub. The finished objectives of this project are the following: 1) Established the theory and implementation of accurate full-field 3D shape measurement system of specular surfaces based on direct phase-to-depth relationship; 2) Studied a novel 3D calibration method to build up the relationship between the absolute phase map and the 3D shape data in a simple, flexible and automatic way; 3) Analysed the effects of system parameters on the measured 3D shape in a simulated way, and all kinds of error sources and their effects on the measured 3D shape data and gave their compensation methods for obtaining high accurate 3D shape data; 4) Gained new knowledge and training about advanced metrology from the hosting organisation, transferred new optical metrology to the hosting organisation, and built up a solid foundation for further collaboration between the researcher and the Future Metrology Hub by applying for a Sino-UK Workshop.

Цел на проекта
With the advent of advanced manufacturing technology and the advent of intelligent manufacturing, it is becoming more and more important to fast and accurately measure 3D shape of components surface, especially specular objects, in the process of intelligent manufacturing, which is a guarantee to improve the product quality. This project will solve the challenging problems in deflectometry. If successful the project will open the door to a host of new instrumentation devices. The project will address the fundamental problems how to avoid the integration procedure in deflectometry - a problem that has seriously obstructed the development of measuring the complicated specular surfaces. I propose a novel direct phase-to-depth deflectometry for accurately measuring full-field 3D shape of specular objects with isolated and/or discontinuous surfaces. In addition, I will develop a new instrumentation system using the phase-to-depth deflectometry technique. Two new techniques and research methods will be studied to realize phase-to-depth deflectometry: 1) display the same fringe patterns on two screens, 2) display two set of fringe patterns on one screen. A novel 3D calibration method will be developed to determine the relationship between phase map and 3D shape data by using a white plate and a plane mirror, both having ring marks on the surface. Such application will greatly promote 3D measurement technologies and should lead to significant economic and societal benefits to Europe. Through this Fellowship, I will gain new knowledge and training about advanced optical metrology to keep the international standing as a leading researcher. Therefore, this Fellowship has not only important practical application value in quality assurance of products in the fields of intelligent manufacturing, but important theoretical significance for research and developments in optical metrology.
