Fully automated mosaicking of pushbroom aerial imagery

2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008
This communication addresses the problem of the automatic mosaicking of raw images acquired by airborne pushbroom imagers. Using appropriate ancillary data issued from GPS and inertial measurements, we show how the mutual information criterion can be used to improve the co-registration and direct georeferencing of overlapping flight lines by estimating

Novel faceted mirror for pushbroom IR sensor

SPIE Proceedings, 2004
A novel pushbroom sensor concept is introduced which incorporates a faceted field-condensing mirror to image the same ground pixel simultaneously in several spectral bands, while eliminating temporal misregistration and MTF smear due to earth rotation. This paper presents an overview of the instrument concept and the fabrication and performance details

Development of Chinese pushbroom hyperspectral imager (PHI)

SPIE Proceedings, 1998
As a remote sensing instrument, pushbroom hyperspectral imager demonstrates its advantages in many application operations. It brings people better spectral resolution with high signal-to-noise-ratio. As increase of the demand of environment study and city planning. In 1997 Pushbroom Hyperspectral Imager (PHI) was built in Shanghai.

Lexisearch for Modeling Pushbroom Imaging Systems

Proceedings of the 2019 3rd International Symposium on Computer Science and Intelligent Control, 2019
The present study aims at exploiting lexicographic search(lexi-search in short) technique for modeling push broom imaging systems on board a spacecraft. Conventional techniques use a full force rigorous orbital photogrammetric model adopting iterative least squares techniques with partial derivatives of adjustment equations involving Taylor's series ...

Pushbroom microwave radiometer results from HAPEX-MOBILHY

Remote Sensing of Environment, 1993
Abstract The NASA C-130 remote sensing aircraft was in Toulouse, France from 25 May through 4 July 1986, for participation in the HAPEX-MOBILHY program. Spectral and radiometric data were collected by C-130 borne sensors in the visible, infrared, and microwave wavelengths.

Spatial PSF Nonuniformity Effects in Airborne Pushbroom Imaging Spectrometry Data

IEEE Transactions on Geoscience and Remote Sensing, 2007
Efficient and accurate imaging spectroscopy data processing asks for perfectly consistent (i.e., ideally uniform) data in both the spectral and spatial dimensions. However, real pushbroom-type imaging spectrometers are affected by various point spread function (PSF) nonuniformity artifacts.

Prediction of Georeferencing Precision of Pushbroom Scanner Images

IEEE Transactions on Geoscience and Remote Sensing, 2012
The precision of georeferencing of pushbroom satellite images without using ground control points is estimated. The study includes what-if scenarios for various precisions of star trackers, GPS receivers, image acquisition timing, interior camera parameters, and digital elevation model (DEM).
