3D surface modeling based on data from the mobile measurement platform

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.
