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...
A COMPARISON OF OBJECT-BASED AND PIXEL-BASED APPROACHES TO ESTIMATE LIDAR-MEASURED FOREST CANOPY HEIGHT USING QUICKBIRD IMAGERY
Canopy height Geographic object-based image analysis
2015/11/16
Canopy surface height (CSH) is a significant forest biophysical parameter to estimate above-ground biomass and carbon content.
High- spatial resolution optical remotely sensed data have shown promis...
