In this paper, a new method for estimation of vertical leaf area density (LAD) profile of tree canopy using portable scanning lidar is proposed. In this method, which we refer to as the voxel-based ...
This project has two main purposes; the first is to perform deciduous-coniferous classification for 65 trees by using the leaf-on single flight LiDAR data. It was done by looking at the geometrical ...
In times of higher market prices of fossil fuels and to meet the increasingly environmental and economic threads of climate change renewable energy must play a major role for global energy supply. Th...
In the last few years, LIDAR and image-matching techniques have been employed in many application fields because of their quickness in point cloud generation. Nevertheless, these techniques do not a...
Digital terrain model (DTM) is one of the important input parameters in urban flood application. This is because it influences the flow direction, flow velocity, flood extend and flood depth. LiDAR ...
LIDAR is a powerful remote sensing technology for acquisition of 3D information from terrain surface. Algorithms used for LIDAR data in urban area are used mostly to deal with the 3D points cloud an...
Light Detection and Ranging (LIDAR) is a technology used for collecting topographic data. Nowadays there are diverse application areas of LIDAR data that include DTM generation and building extraction...
The Great Wall is one of the biggest man-made wonders of the world! The wall consists of bricks made by different dynasties and built on thousands of kilometers of steep mountain terrain. It has many ...
There are over 10 sets of LiDAR system into China until end of 2007, but they did not in full of working. One reason is big capacity of the market need a long period time. Another is author of this ar...
This paper proposes an automatic system which detects buildings in urban and rural areas by the use of first pulse return and last pulse return LIDAR data. Initially both first and last pulse return p...
Automated and reliable 3D reconstruction of man-made structures is important for various applications in virtual reality, city modeling, military training, etc. This paper is concerned with the automa...
Recently, automatic object extraction from Light Detection And Ranging (LiDAR) data has attracted great attention. The level of detail and the quality of the collected point cloud motivated the resear...
The analysis of LIDAR data to extract surface features is of great interest in photogrammetric research. Our investigations show that the same material of a surfaces (e.g. gabled roof) yields to diffe...
The automatic detection and 3D modeling of objects at airports is an important issue for the EU FP6 project PEGASE. PEGASE is a feasibility study of a new 24/7 navigation system, which could either re...
For the moment the total length of Chinese powerline is at the second place of the whole world. During the Eleventh Five-Year Plan the government will enhance the construction of power grid to supply ...
