| 摘 要： | 针对目前四轴激光测量机的不足,设计了一种五轴逆向工程点云数据采集系统;在四轴的基础上增加了激光测头的旋转轴,采用基于PCI总线的运动控制系统及USB总线的数据采集系统,并植入了图像采集系统,通过二次开发技术利用Windows的应用程序编程接口函数对扫描范围进行自动识别;软件系统使用了采集路径规划及测量数据优化处理算法;在原始数据测量及曲面反求建模两个方面进行了实例应用,零件大斜度面和垂直于工作台的表面均能覆盖测量,并且所有点云数据是一次测量完成,实验结果验证了本系统的可行性与稳定性。

| Abstract: | To against the demerits of four-axis laser measuring system,a reverse engineering point cloud data acquisition system with five-axis was developed.The rotation axis of laser probe was designed on the basis of four-axis system.The system adopted PCI-Bus motion control card and USB-Bus data acquisition card.The image acquisition system was used to recognize scanned area by adopting secondary development technology with windows application programming interface.The path planning and data optimization were used in the software system.Applications of original data acquisition and reverse modeling show that the oblique surface with large-angle even perpendicular to the working platform can be measuring.The reverse engineering point cloud data collection system is available and stable. |
