Abstract

By the evolution of 3D scanning techniques, creating 3D models of real world objects is getting much easier. Beyond the humansized objects one can easily scan complete buildings, roads, squares, or even towns and countries as well. The raw data that scanning technologies, such that LIDARs or photogrammetry based applications can provide are point clouds. The size of such a point cloud can be enormous, with billions of points, and processing and converting it to another format is very costly. Due to this it is important to efficiently visualise large point clouds and make it possible to modify them. In this paper we give a brief overview of point cloud visualisation techniques and describe our system that provides tools to manipulate point clouds by selecting, annotating, deleting, cleaning necessary parts of them.
