A Framework for 3D Pushbroom Imaging [PDF]
, 2003 Pushbroom cameras produce one-dimensional images of a scene with high resolution at a high frame-rate. As a result, they provide superior data compared to conventional two-dimensional cameras in cases where the scene of interest can be temporally scanned.

Pushbroom Stereo for High-Speed Navigation in Cluttered Environments [PDF]
2015 IEEE International Conference on Robotics and Automation (ICRA), 2014 We present a novel stereo vision algorithm that is capable of obstacle detection on a mobile-CPU processor at 120 frames per second. Our system performs a subset of standard block-matching stereo processing, searching only for obstacles at a single depth.

Reduction of Radiometric Miscalibration—Applications to Pushbroom Sensors [PDF]
Sensors, 2011 The analysis of hyperspectral images is an important task in Remote Sensing. Foregoing radiometric calibration results in the assignment of incident electromagnetic radiation to digital numbers and reduces the striping caused by slightly different ...

REAL TIME PROCESSING FOR EPIPOLAR RESAMPLING OF LINEAR PUSHBROOM IMAGERY BASED ON THE FAST ALGORITHM FOR BEST SCAN LINE SEARCHING [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013 The epipolar resampling of linear pushbroom imagery is essential for automatic DEM extraction and feature collection. Due to the special imaging geometry of linear array scanners, the epipolar geometry of linear pushbroom imagery is very complex. In this

Earth Observation via Compressive Sensing: The Effect of Satellite Motion
Remote Sensing, 2022 In the framework of earth observation for scientific purposes, we consider a multiband spatial compressive sensing (CS) acquisition system, based on a pushbroom scanning. We conduct a series of analyses to address the effects of the satellite movement on

Estimating satellite attitude from pushbroom sensors [PDF]
2010 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2010 Linear pushbroom cameras are widely used in passive remote sensing from space as they provide high resolution images. In earth observation applications, where several pushbroom sensors are mounted in a single focal plane, small dynamic disturbances of the satellite's orientation lead to noticeable geometrical distortions in the images.

THE USE OF EXISTING GLOBAL ELEVATION DATASET FOR ABSOLUTE ORIENTATION OF HIGH RESOLUTION IMAGE WITHOUT GCPS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 For precise mapping using high resolution satellite images, various ways to eliminate the need of ground control points have been proposed. DEM matching, a technique to match two different surfaces by adjusting their position and attitude, is also one ...
