Terrestrial Laser Scanning for Plot-Scale Forest Measurement
Plot-scale measurements have been the foundation for forest surveys and reporting for over 200 years. Through recent integration with airborne and satellite remote sensing, manual measurements of vegetation structure at the plot scale are now the basis for landscape, continental and international mapping of our forest resources. The use of terrestrial laser scanning (TLS) for plot-scale measure...
متن کاملQuality Analysis and Correction of Mobile Backpack Laser Scanning Data
Backpack laser scanning systems have emerged recently enabling fast data collection and flexibility to make measurements also in areas that cannot be reached with, for example, vehicle-based laser scanners. Backpack laser scanning systems have been developed both for indoor and outdoor use. We have developed a quality analysis process in which the quality of backpack laser scanning data is eval...
متن کاملTerrestrial laser scanning to estimate plot-level forest canopy fuel properties
This paper evaluates the potential of a terrestrial laser scanner (TLS) to characterize forest canopy fuel characteristics at plot level. Several canopy properties, namely canopy height, canopy cover, canopy base height and fuel strata gapwere estimated. Different approaches were tested to avoid the effect of canopy shadowing on canopy height estimation caused by deployment of the TLS below the...
متن کاملAutomatic Plot-wise Tree Location Mapping Using Single-scan Terrestrial Laser Scanning
The application of terrestrial laser scanning (TLS) has received increasing attention in the quantitative forest inventories. Both single-scan and multi-scan TLS can be employed for the forest parameter retrieval. The multi-scan mode captures an ideal data set, which in general provides whole tree coverage and leads to accurate tree trunk detection and modelling. The single-scan data is, howeve...
متن کاملPose Graph Compression for Laser-Based SLAM
The pose graph is a central data structure in graph-based SLAM approaches. It encodes the poses of the robot during data acquisition as well as spatial constraints between them. The size of the pose graph has a direct influence on the runtime and the memory requirements of a SLAM system since it is typically used to make data associations and within the optimization procedure. In this paper, we...
