本文介绍了一种基于三维视觉传感器和三坐标测量机（CMM）测量信息集成的复杂曲面反求工程新方法。其目的是以高精度重建复杂几何形状物体的CAD模型，同时快速利用光学和机械传感器的兴起所带来的优势，以最少的人为干预。在测量信息层面上，在一个模块内进行组合，用于智能聚合来自光学和机械传感器的信息。开发了用于对视觉传感器的3D图像和坐标测量机的数字化点云进行数字化、滤波、分组和表面拟合的工具。本文介绍了该组合系统，并介绍了两个工业应用。
This paper describes a novel methodology for the reverse engineering of complex, fi ee form surfaces, based on the integration of the measurement information from a 3D vision sensor and a coordinate measuring machine (CMM). The aim is to reconstruct the CAD model of objects of complex geometry with high accuracy and at the same time, rapidly exploiting the advantages deriving from the rise of both the optical and the mechanical sensors, with a minimum of human intervention The combination is performed at the level of measurement information, within a module for the intelligent aggregation of the information from optical and mechanical sensors. Tools are developed for digitising, filtering, grouping and surface-fitting the 3D images of the vision sensor and the point clouds fi-om digitisation of the CMM. In the paper the combined system is described, and two industrial applications are presented.
