自由曲面的测量可通过各种接触或非接触的方法实现;自由曲面的反求由自由曲面的测量、特征提取以及曲面构造组成。本文通过该过程,构造出吊钩的整个曲面。
Measurement of free-form surfaces can be achieved by various methods of contact or non-contact; the inverse of free-form surfaces consists of measurements of free-form surfaces, feature extraction, and surface texture. Through this process, the entire surface of the hook is constructed.
