Self-calibration of the Trimble (mensi) Gs200 Terrestrial Laser Scanner
Terrestrial laser scanning (TLS) is a widely used technology for acquiring dense and accurate 3D information of a scene. The features and capabilities of modern TLS systems have opened the market to many new fields, such as earth science and the movie production industry. To ensure that the best quality data are captured with a TLS instrument the system needs to be free of systematic distortion...
متن کاملSelf-calibration and Evaluation of the Trimble Gx Terrestrial Laser Scanner
There are numerous imaging modalities for reconstructing 3D object space on the market. Among all the varieties, which include 3D TOF range cameras, structured light systems, and traditional photogrammetric systems, terrestrial laser scanners have gained the most attention and demand from the surveying and engineering discipline. This is probably because of the large field of view and rapid den...
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 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 کاملThe Impact of Angle Parameterisation on Terrestrial Laser Scanner Self-calibration
The angular fields of view in which a terrestrial laser scanner captures data differ according to instrument construction. Both the socalled panoramic and hybrid instruments scan through a full horizontal field of view but their vertical fields of view can differ considerably in terms of range and mode of data acquisition. The differences in operational mode govern the allowable range for each ...
