Compact camera for multispectral and conventional imaging based on patterned filters
(2014)
A multispectral camera concept is presented. The concept is based on using a patterned filter in the focal plane, combined with scanning of the field of view. The filter layout has stripes of different bandpass filters ...
Extraction and classification of vehicles in LADAR imagery
(2013)
The work presented in this paper is based on a dataset recorded with an airborne sensor. It comprises targets like M-60, M-47, M-113, bridge layers, tank retrievers, and trucks in various types of scenes. The background-object ...
Real-time anomaly detection in hyperspectral images using multivariate normal mixture models and GPU processing
(2009)
Hyperspectral imaging, which records a detailed spectrum of light arriving in each pixel, has many potential uses in remote sensing as well as other application areas. Practical applications will typically require real-time ...
Real-time georeferencing for an airborne hyperspectral imaging system
(2011)
The paper describes the georeferencing part of an airborne hyperspectral imaging system based on pushbroom scanning. Using ray-tracing methods from computer graphics and a highly efficient representation of the digital ...
Anisotropic scattered data interpolation for pushbroom image rectification
(2014)
This paper deals with fast and accurate visualization of pushbroom image data from airborne and spaceborne platforms. A pushbroom sensor acquires images in a line-scanning fashion, and this results in scattered input data ...
Characterization of a compact 6-band multifunctional camera based on patterned spectral filters in the focal plane
(2014)
In some applications of multi- or hyperspectral imaging, it is important to have a compact sensor. The most compact spectral imaging sensors are based on spectral filtering in the focal plane. For hyperspectral imaging, ...
Compact multispectral multi-camera imaging system for small UAVs
(2016)
Cameras with filters in the focal plane provide the most compact solution for multispectral imaging. A small UAV can carry multiple such cameras, providing large area coverage rate at high spatial resolution. We investigate ...
An ATR architecture for algorithm development and testing
(2013)
A research platform with four cameras in the infrared and visible spectral domains is under development at the Norwegian Defence Research Establishment (FFI). The platform will be mounted on a high-speed jet aircraft and ...
LandX20 Experiment Report – experiment for future land warfare capabilities with focus on increased situational awareness and unmanned systems
(2022-03-21)
LandX20 was a collaborative experiment and demonstration where four research projects from the
Norwegian Defence Research Establishment (FFI) participated. The goal of the experiment was
two-fold. The first goal was to ...
Multimodal Multispectral Imaging System for Small UAVs
(2020-01-17)
Multispectral imaging is an attractive sensing modality for small unmanned aerial vehicles (UAVs) in numerous applications. The most compact spectral camera architecture is based on spectral filters in the focal plane. ...
