EXTERIOR ORIENTATION OF HYPERSPECTRAL FRAME IMAGES COLLECTED WITH UAV FOR FOREST APPLICATIONS
Forest Hyperspectral Image Orientation Sparse Control UAV
2016/3/25
This paper describes a preliminary study on the image orientation acquired by a hyperspectral frame camera for applications in small tropical forest areas with dense vegetation. Since access to the in...
METHODS FOR THE AUTOMATIC GEOMETRIC REGISTRATION OF TERRESTRIAL LASER SCANNER POINT CLOUDS IN FOREST STANDS
Terrestrial laser scanning forest stands registration sphere extraction tree axes
2016/2/29
A combined analysis of multiple terrestrial laser scanner point clouds recorded from different positions requires a geometric
registration of these scans. In most applications of terrestrial laser s...
Processing lidar waveform data for 3D visual assessment of forest environments
Forestry Full Waveform Lidar 3D modelling Visual representation
2014/7/30
The objective of this report is to present and discuss a work-flow for extracting, from full-waveform (FW) lidar data, formats which are compatible with common information systems (GIS) and statistica...
Interactive Trunk Extraction from Forest Point Cloud
Terrestrial Laser Scanning Forest, User-Interaction
2014/7/30
For forest management or monitoring, it is required to constantly measure several parameters of each tree, such as height, diameter at breast height, and trunk volume. Terrestrial laser scanner has be...
THE FUSION OF INDIVIDUAL TREE DETECTION AND VISUAL INTERPRETATION IN ASSESSMENT OF FOREST VARIABLES FROM LASER POINT CLOUDS
Forest inventory plot-wise measurements individual tree detection
2014/6/5
In this study we searched the obtainable accuracy of forest inventory based on the individual tree detection (ITD) by using fusion of automatic ITD (ITDauto) and visual interpretation of laser point c...
Forest fires smoke monitoring from Sea-viewing Wide Field-of-view Sensor images
remote sensing forest fires image processing
2011/5/6
A method for detecting forest fires smoke using SeaWiFS (Sea-viewing Wide Field-of View Sensor) images is developed in this paper. The colour masking technique is proposed to extract the maximum fires...
