Optimisation du traitement de nuage de points pour la production de plan de façade au sein d'un cabinet de géomètre-expert

Abstract : The use of laser scanners in surveying firm has become widespread in recent years. The point cloud obtained is curently very little used at its fair value and the information contained is underutilized. The purpose of this paper is to propose solutions and methods of automated or semi-automated processes to simplify the creation of elevation plans. In order to achieve this, two algorithms were particularly used during this study : the RANSAC algorithm and the region growing algorithm. These iterative methods, applied to a large amounts of data, are time consuming. This is why alternative versions, adapted to our case study, have been proposed. The point cloud has been segmented into elements sharing common characteristics, then a method of edge points detection and vectorization was implemented to produce a two-dimensional vector model.
