摘 要: 基于视觉的三维测量技术在逆向工程等领域得到了广泛的应用,主要可分为主动视觉和被动视觉两类。本文对在工程实践中应用较多的主动视觉和被动视觉技术分别进行了论述,分析了各种方法的基本原理及主要的优缺点;并对一些有代表性的视觉系统进行了介绍,最后对基于视觉的数字化方法与系统进行了总结和展望。 3D optical measurement technique based on vision is widely applied in reverse engineering, and it can be divided mainly in active vision and passive vision. Current 3D - shape acquisition using both active and passive vision techniques was introduced, its operation principle and inherent advantages and limitations were analyzed. Some representative vision systems were introduced, the developments of vision technique and systems were discussed.
