Abstract

The paper is aimed at presentation of the results obtained in the process of designing, constructing and experimental testing of the laser measurement system based on the 2D laser scanner of the LD-OEM1000 type in road applications. The aim of this work is to create a 3D model with surface of real objects, for example 3D model of an interior and exterior of buildings, tunnels, roads or road surrounding areas. For that purpose we have developed a mobile measurement platform. It consists of two lasers scanners, seven cameras, GPS receiver, server, switch and UPS. The angular range of the first laser scanner is 360 degrees and distance which we can measure is about 250m. We use this scanner to measure surrounding environment. The second scanner is used for more precise measurement. Its angular range is 70 degree and measurement range is about 2.4 m. To calculate a cloud of points we use our own algorithm based on our equations. For visualization we use *.obj file type which may be open in many programs. The algorithm for surface creation is based on finding the nearest point. To find the nearest point, the algorithm uses distance and axis difference between points. From these data the algorithm can create surface.
基于移动测量平台数据的三维曲面建模
本文介绍了基于LD-OEM1000型二维激光扫描仪的激光测量系统在道路应用中的设计、构建和实验测试过程中所取得的结果。这项工作的目的是创建一个具有真实物体表面的3D模型,例如建筑物,隧道,道路或道路周围区域的内部和外部的3D模型。为此,我们开发了一个移动测量平台。它由两个激光扫描仪、七个摄像头、GPS接收器、服务器、开关和UPS组成。第一台激光扫描器的角度范围为360度,我们可以测量的距离约为250m。我们用这个扫描仪来测量周围的环境。第二个扫描仪用于更精确的测量。其角度范围为70度,测量范围约为2.4米。为了计算点云,我们使用基于方程的自己的算法。对于可视化,我们使用*。Obj文件类型,可以在许多程序中打开。曲面创建的算法是基于找到最近的点。为了找到最近的点,算法使用点之间的距离和轴差。该算法可以从这些数据中创建曲面。
