3D Modelling of Individual Trees Using Full-waveform Lidar

For the last few decades, analysis of forest area has been conducted using remote sensing techniques such as aerial photogrammetry, satellite imagery, synthetic aperture radar and lidar. Airborne laser scanning in particular offers a cost-effective, versatile, operationally flexible and robust sampling tool for forest management. There is a growing industry trend towards techniques of ‘precisio...

3d Segmentation of Full Waveform Lidar Data for Single Tree Detection Using Normalized Cut

The study highlights a novel method to segment single trees in 3D from dense airborne full waveform LIDAR data using the normalized cut segmentation. The key idea is to subdivide the tree area in a voxel space and to setup a bipartite graph which is formed by the voxels and similarity measures between the voxels. The normalized cut segmentation divides the graph hierarchically into segments whi...

A Method for Detecting Windows from Mobile LiDAR Data

One Sentence: This paper presents a novel method for window detection from mobile LiDAR data. Abstract: Mobile LiDAR (Light Detection And Ranging) data collection is a rapidly emerging technology in which multiple georeferenced sensors (e.g., laser scanners, cameras) are mounted on a moving vehicle to collect real world data. The photorealistic modeling of large-scale real world scenes such as ...

Terrain surfaces and 3D landcover classification from small footprint full-waveform lidar data: Application to badlands

This article presents the use of new remote sensing data acquired from airborne full-waveform lidar systems. They are active sensors which record altimeter profiles. This paper introduces a set of methodologies for processing these data. These techniques are then applied to a particular landscape, the badlands, but the methodologies are designed to be applied to any other landscape. Indeed, the...

Terrain Roughness Parameters from Full-waveform Airborne Lidar Data

As an active remote sensing technique airborne laser scanning (ALS) is able to capture the topography with high precision even for densely forested areas. Due to the high pulse repetition frequency of up to 400 kHz a high sampling rate on the ground can be achieved, which allows the description of the terrain surface in decimeter scale. In this contribution two approaches to characterize terrai...
