Mobile laser scanning (MLS) is time-efficient technology of geospatial data collection that proved its ability to provide
accurate measurements in many fields. Mobile innovation of the terrestrial la...
Accuracy of Structure from Motion models in comparison with terrestrial laser scanner for the analysis of DBH and height influence on error behaviour
hand-held digital camera point cloud stem optimization image segmentation photogrammetry
2016/9/2
With the advantage of Structure from Motion technique, we reconstructed three-dimensional structures from two-dimensional image sequences in a circular plot with a radius of 6 m. The main objective of...
Estimating Vertical Distribution of Vegetation Cover in Temperate Heterogeneous Forests Using Airborne Laser Scanning Data
Forest Structure Remote Sensing Airborne Laser Scanning
2012/7/4
Vertical structure is important for understanding forest environment, yet difficult to characterize, especially in temperate heterogeneous forests where the structure is complex. This study used data ...
