自动三维坐标测量仪测量路径规划技术研究

摘要在现代工业测量的领域里，三维坐标测量使用越发广泛。三维坐标测量仪主要用于高精度的几何零部件和形状复杂的机械零部件的测量。三维坐标测量也是目前研究的一个重要课题。

本项目旨在建立一个自动三维坐标测量系统，使用VC++编写的程序打开图纸（图纸以DXF形式存在），读取图纸中点的三维坐标的信息，并通过串口发送给控制器。控制器接收到PC机的指令后进行解析，并且发送命令指示电机运动，同时通过路径规划指导测头的移动，从而测出工件点的三维坐标。本文重点介绍DXF文件格式以及通过编写软件来读取DXF格式图纸的信息，提取三维坐标，设计相应的测量路径，实现路径规划。本文将重点阐述路径规划软件的设计方案。79545

Title Technical study on automatic 3D coordinate measuring instrument measuring path planning

Abstract In the field of modern industrial measurement, 3D coordinate measurement is used more widely。 Three-dimensional coordinate measuring machine is mainly used for the measurement of high-precision geometric components and complex shapes of mechanical parts。 3D coordinate measurement is an important subject of the present study。 The project aims to establish an automated three-dimensional coordinate measuring system。 Using VC++ to write a program to open the drawings (drawings in the form of DXF), so as to read the drawings of the three-dimensional coordinates information of points in the drawings, then pass through the serial port to controller。 After receiving an instruction from the PC ，controller will resolve, and order the motor to move through sending commands。 And the probe will be directed to move through path planning, so as to measure the 3D coordinates of the points of the work piece。 In this paper, we will focus on the format of the DXF file and how to read the DXF format drawings by writing software, so as to extract the three-dimensional coordinates。 Then design appropriate measurement path, realize path planning。 This paper will focus on software design for path planning。
