摘要
为提高新型矿车的开发水平,降低其研发的人力物力,研究设计了一种基于三维照相扫描仪的新型矿车开发方法。通过Focus 350三维扫描仪等硬件获得新型矿车驾驶室上部的点云数据,并采用Geomagic Studio软件对不同位置、不同摄像头的点云数据开展了连接、滤波、精简以及插补操作,由CATIA软件完成了新型矿车驾驶室上部的曲面重构,建立了曲面重建光顺性的评价方法,得知所重建新型矿车驾驶室上部曲面模型曲率变化的最大值为0.012 mm^-1,最小值为-0.838 mm^-1。最终,通过上述研究方法对整车进行开发与加工制造。该研究可为我国自主研发新型矿车提供理论参考与依据。
In order to improve the development level of rubber-tyred vehicle(RV)and reduce the manpower and material resources in its development,a new development method of RV based on 3D camera scanner is studied and designed.Through the Focus 3503D scanner and other hardware,the point cloud data on the upper part of the RV cab is obtained,and the point cloud data of different positions and different cameras are connected,filtered,simplified and interpolated by the Geographic Studio software.The surface reconstruction on the upper part of the RV cab is completed by CATIA software,and the evaluation method for the smoothness of the surface reconstruction is established.It is concluded that the maximum curvature change of the surface model of the upper cab is 0.012 mm^-1 and the minimum is-0.838 mm^-1.Finally,through the above research methods,the whole vehicle is developed and manufactured.This research can provide theoretical reference and basis for the independent research and development of RV in China.
