摘要
零件三维逆向工程对当今的机械制造业具有重大意义,其中,三维表面数据测量是三维模型重建的前提,即是逆向工程的关键步骤之一。而非接触式激光测量技术是今后逆向工程中三维表面数据获取的发展趋势。基于光学三角法测量原理,本文设计了一种非接触式激光测量系统平台,包括主要硬件的选取、硬件系统搭建和VC++软件系统设计。通过一个凹槽零件的实验测量,得到了零件的形状数据,验证了该测量系统的可行性。
Nowadays, reverse engineering is very important for mechanical manufacturing. As one of the key processes of reverse engineering, three dimensional surface data measurement is the basis of three dimensional model reconstruction. And non-contact laser measurement technology leads the development of three dimensional surface data acquirement. In this paper, based on optical trigonometry theory, a non-contact laser measurement system was designed and implemented including the selection of the main hardware, the construction of the hardware system, and the design of the VC++ software system. The feasibility of the measurement system was testified through a groove model measureing and the surface data acquiring.
