Automatic Registration of Laser Scanned Color Point Clouds Based on Common Feature Extraction
Point cloud data acquisition with laser scanners provides an effective way for 3D as-built modeling of a construction site. Due to the limited view of a scan, multiple scans are required to cover the whole scene, and a registration process is needed to merge them together. The aim of this paper is to introduce a novel method that automatically registers colored 3D point cloud sets without using...
متن کاملAutonomous Modeling of Pipes within Point Clouds
Three-dimensional models are in increasing demand for design, maintenance, operations and construction project management. Point-clouds are the main output of automatic data collection using laser-scanners and photogrammetric technologies. Pipe-works may comprise 50% of the value of important construction projects such as industrial and research facilities. We have developed a practical and cos...
متن کاملRecognising Structure in Laser Scanner Point Clouds
Both airborne and terrestrial laser scanners are used to capture large point clouds of the objects under study. Although for some applications, direct measurements in the point clouds may already suffice, most applications require an automatic processing of the point clouds to extract information on the shape of the recorded objects. This processing often involves the recognition of specific ge...
متن کاملExtraction of Lines from Laser Point Clouds
Three dimensional building models have become important during the past for various applications like urban planning, enhanced navigation or visualization of touristy or historic objects. 3D models can increase the understanding and explanation of complex urban scenes and support decision processes. A 3D model of the urban environment gives the possibility for simulation and rehearsal, to "fly ...
متن کاملOutlier Detection in Laser Scanner Point Clouds
Outlier detection in laser scanner point clouds is an essential process before the modelling step. However, the number of points in the generated point cloud is in the order of million points, so (semi) automatic approaches are necessary. Having introduced the sources of outliers in typical laser scanner point clouds, an outlier detection algorithm using a density based algorithm is addressed. ...
