摘要

由于加工装配误差等原因，飞机壁板工件的数学模型和实际模型往往不一致。为解决不一致导致的制孔位置精度差的问题，提出了一种基于双目测量系统的孔位补偿方案。为了能够更好地设计满足制孔需要的视觉测量系统，分析了机器人自动化制孔系统的工作流程。然后介绍了视觉测量系统组成和工作流程，最后分别对视觉测量系统的基准孔三维坐标提取、孔位误差补偿、数据库读写3 个重要功能的技术进行了详细的介绍。通过该双目视觉测量系统的孔位补偿方法，可以获取基准孔的三维坐标，对孔位误差进行补偿，补偿信息写入数据库，提高机器人自动化制孔系统的制孔位置精度。

Abstract

The machining and assembly errors will result in misalignment between the real and nominal 3D models of aircraft panel. To solve the low position accuracy of holes caused by the misalignment

a positional error compensation method based on binocular vision measurement system is proposed. Firstly

the workflow of the robotic drilling system is introduced to choose a vision measurement system that can meet the drilling requirement. Then the component and the workflow of the vision measurement system are proposed. Finally

the coordinate extraction of datum holes

the error compensation of holes and database operation in the vision measurement system are introduced in detail. The positional error compensation method based on binocular vision measurement system can obtain the coordinate of datum holes

compensate the positional errors of holes

and write the compensation information in the database to enhance the position accuracy of holes.
