基于计算机视觉的自由曲面逆向工程关键技术

On Reverse Engineering Based on ComputerVision for Free-form Surface

逆向工程是自由曲面建模的重要方法，基于计算机视觉的逆向工程成为工业界和学术界研究的热点问题之一。首先给出逆向工程的概念，然后综述了基于计算机视觉的逆向工程关键技术，包括曲面数字化、测量规划和曲面重构，最后指出该领域尚待进一步研究的问题。

Reverse engineering is an importmant method for modeling the free-form surface. The reverseengineering based on computer vision is becoming to the focus topic. After defining the concept of reverse en-gineering, the key techniques of reverse engineering for free-form surface, such as digitizing, planning ofmeasurement and reconstructing, are surveyed. In the end, the some topics awaiting to be further studied areproposed in this field.
