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 ...
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 ...
Estimating the pixel footprint distribution for image fusion by ray tracing lines of sight in a Monte Carlo scheme
(2013)
Images from airborne cameras can be a valuable resource for data fusion, but this typically requires them to be georeferenced. This usually implies that the information of every pixel should be accompanied by a single ...
Compact multimodal multispectral sensor system for tactical reconnaissance
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2022-09-30)
Multispectral imaging is an attractive sensing modality for small unmanned aerial vehicles (UAVs) in numerous military and civilian applications such as reconnaissance, target detection, and precision agriculture. Cameras ...
