Processing of laser scanning data for wooded areas
Airborne laser scanners have been increasingly used in recent years for the collection of terrain elevation data especially in wooded areas. The technology demands new processing technologies which have reached a stage of good practical application so far for the interpolatin of ground DTMs. Beyond pure ground DTMs, however, laser scanner data have great potential for other applications such as...
متن کاملIterative processing of laser scanning data by full waveform analysis
The latest developments in laser scanners allow capturing and digitizing of the full waveform of the backscattered pulse. The waveform can be analyzed for measurement features such as range, reflectance values and spreading of the pulse. These features are used to distinguish between locally planar surface elements and partly penetrable objects caused by partial occlusions. This presegmentation...
متن کاملThe Opals Data Manager – Efficient Data Management for Processing Large Airborne Laser Scanning Projects
The fast measurement rate of today’s Airborne Laser Scanners results in billions of points for single ALS projects. Efficient algorithms and data management methods are, therefore, a precondition for successful project handling. The software package OPALS (Orientation and Processing of Airborne Laser Scanning data) was especially designed to meet those criteria. Central core of the package is t...
متن کاملDenoising of Laser Scanning Data using Wavelet
Regarding the terrestrial laser scanning accuracy, one of the main problems is the noise in measured distance which is necessary for the spatial coordinates ́ determination. In this paper the technique of using the wavelet transformation for the reduction of the noise in the laser scanning data is described. This method of filtration is made in “post processing” and due to this fact any changes ...
متن کاملSegmentation-based Classification of Laser Scanning Data
Over the past few years, laser scanning has been established as a leading technology for the acquisition of high density 3D spatial information. Digital Terrain Models (DTMs), which can be used for different engineering applications, are obtained by classification of laser data and removing the points that do not belong to terrain surface. The commonly used methods for the classification of las...
