Research on Building Measurement Accuracy Verification Based on Terrestrial 3D Laser Scanner

Deformation Monitor Based on 3d Laser Scanner

It introduces the methods of deformation monitoring based on 3D laser scanner. The point clouds obtained by multi-period scanning for deformation monitored object are registered. The coordinate system of point cloud is unified. Constraint stability is tested through two methods. The deformation and trends are analyzed according to the variations of coordinates of center point modeled targets an...

Occlusion Area as Suitable Guidance for Terrestrial Laser Scanner Localization

Terrestrial Laser Scanner (TLS) technology, have altered quickly data acquisition for map production in surveying. In many cases, it is impossible to complete surveying of the desired area without TLS displacement in one station to another. Occlusion is innate in data acquisition, with this type of device. To solve this problem, TLS devices should be placed in different locations and scanning o...

3D Map Building Using a 2D Laser Scanner

In this paper we present a technique to build 3D maps of the environment using a 2D laser scanner combined with a robot’s action model. This paper demonstrates that it is possible to build 3D maps in a cheap way using an angled 2D laser. We introduce a scan matching method to minimize the odometer errors of the robotics platform. Some experimental results and conclusions are presented.

Virtual Building Maintenance: Enhancing Building Maintenance Using 3D-GIS and 3D Laser Scanner (VR) Technology

The renovation and refurbishment market is rapidly expanding within the construction industry, bringing the role of the Facilities Management (FM) department to the forefront. Operating and maintaining a facility however, takes the biggest proportion of the lifecycle cost of a building, which can be costly and time consuming. The wide spread and use of advanced technologies within the construct...
