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 کاملCalibration and Testing of a Terrestrial Laser Scanner
Terrestrial laser imaging systems offer a new means for rapid precise mapping of objects up to ranges of up to a few hundred metres from the instrument location. The high sampling frequency (e.g., several kilohertz) available from such instrumentation can provide a spatial data density of directly observed co-ordinates far in excess of that available with photogrammetric techniques. For structu...
متن کاملTitle Documentation of Bridges by Terrestrial Laser Scanner
Bridge structures are subjected to deterioration due to excessive usage, overloading, and aging material. For the last two decades, a significant amount research has been developed for collecting data for structural health monitoring. Yet, visual investigation with an on-site inspector remains the predominant method. This is true despite the highly subjective and time consuming aspects of this ...
متن کاملCalibration of a Terrestrial Full Waveform Laser Scanner
Recent advances in Light Detection And Ranging (LiDAR) enable digital acquisition and storage of the entire waveform of backscattered laser pulse energy. Pre-requisites for extracting target radiometric and geometric properties via waveform analysis include defining a model for accurately determining peaks in the return energy waveform and a method for transforming waveform peak amplitudes to a...
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...
