Active hyperspectral LIDAR methods for object classification

2010 2nd Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing, 2010
We have studied the fusion of active hyperspectral and range (LIDAR) data to investigate the concept of an active hyperspectral LIDAR and its potential applications in the remote sensing of vegetation. We have built two prototype instruments using the newly developed supercontinuum laser technique providing a continuous spectrum, which has then been ...

Research on simulating hyperspectral lidar

SPIE Proceedings, 2015
Hyperspectral Lidar using supercontinuum laser as light source, applying spectroscopic technology gets backscattered reflectance of different wavelengths, and can acquire both the geometry and spectral information on the target. In the vegetation detection by using Hyperspectral Lidar, through refusing 3d and spectral data, we can get the physical ...

Hyperspectral and LiDAR Classification With Semisupervised Graph Fusion

IEEE Geoscience and Remote Sensing Letters, 2020
To fuse hyperspectral and Light Detection And Ranging (LiDAR), we propose a semisupervised graph fusion (SSGF) approach. We apply morphological filters to LiDAR and the first few components of hyperspectral data to model the height and spatial information, respectively.

Integrated LiDAR and Hyperspectral

2013
Integrating LiDAR data and hyperspectral imagery is an area of active research in remote sensing, inclusive of application for coastal and coral reef mapping. These two technologies can be combined in a number of different ways, and at a number of stages of processing to produce benthic classification maps.

Tree species classification with hyperspectral imaging and lidar

2016 8th Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2016
This paper presents a new method to discriminate between spruce, pine and birch, which are the dominating tree species in Norwegian forests. For this purpose, simultaneously acquired airborne laser scanning (ALS) and hyperspectral data are used. The laser scanning data was used to mask pixels with low or no vegetation in the hyperspectral data.

Predicting year of plantation with hyperspectral and lidar data

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
This paper introduces a methodology for predicting the year of plantation (YOP) from remote sensing data. The application has important implications in forestry management and inventorying. We exploit hyperspectral and LiDAR data in combination with state-of-the-art machine learning classifiers.

LiDAR-guided analysis of airborne hyperspectral data

2009 First Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing, 2009
This paper describes a new framework to the collection and fusion of multisensor airborne LiDAR and hyperspectral data. We describe a data fusion philosophy that provides a spatially precise positioning of hyperspectral data based on discrete first and last return LiDAR data.

Classification of Hyperspectral and Lidar with Deep Rotation Forest

ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019
In this work, a novel deep rotation forest is proposed to fuse hyperspectral (HS) and LiDAR. First, we extract the spatial and elevation information of two datasets by using morphological filters. Then, each feature source is applied to superpixel segmentation and then are treated as the input of deep rotation forest.

Fusion of hyperspectral and LiDAR data for forest attributes estimation

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
In this paper a system for the fusion of hyperspectral and airborne laser scanning (ALS) data for the estimation of forest attributes is presented. In particular we focused on the classification of tree species, the estimation of stem diameter at breast height (DBH) and the estimation of the stem volume.

Inelastic hyperspectral Scheimpflug lidar for microalgae classification and quantification

Applied Optics, 2021
An inelastic hyperspectral Scheimpflug lidar system was developed for microalgae classification and quantification. The correction for the refraction at the air–glass–water interface was established, making our system suitable for aquatic environments.
