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...
متن کاملVolume Measurement Using a Laser Scanner
This article discusses ways of measuring accuracy of a laser range finder (LRF) using a specially designed calibration cube (with 3D calibration marks) in the context of a particular application (i.e., measuring volumes). We also compare (by means of experiments) two alternative volume estimation methods.
متن کاملTerrain Modelling and Analysis Using Laser Scanner Data
Very detailed high-resolution (3D) digital terrain models can be obtained using airborne laser scanner data. However, laser scanning usually entails huge data sets even for moderate areas, making data management and analysis both complex and time consuming. For this reason, automatic terrain modelling and efficient storage structures supporting data access are needed. In this paper a number of ...
متن کاملRegistration of Terrestrial Laser Scanner Data Using Imagery
Building 3D models using terrestrial laser scanner (TLS) data is currently an active area of research, especially in the fields of heritage recording and site documentation. Multiple TLS scans are often required to generate an occlusion-free 3D model in situations where the object to be recorded has a complex geometry. The first task associated with building 3D models from laser scanner data in...
متن کاملLandslide Monitoring Using Terrestrial Laser Scanner: Georeferencing and Canopy Filtering Issues in a Case Study
In order to define a methodology that faces the major critical issues, we used a Terrestrial Laser Scanner to monitor a large landslide that caused significant disruptions both to an important state road and to a major railway line in Italy. To survey the landslide we used three different models of Terrestrial Laser Scanners, including a "full wave form" one, potentially useful for filtering ve...
