What is Satellite Image Processing and Photogrammetry?
Satellite Image Processing and Photogrammetry is the geometric processing and accuracy assessment of remote sensing imagery from high-resolution satellite sensors, encompassing rational function models, orthorectification, DEM generation, sensor calibration, and geopositioning accuracy.
This field includes 320,246 works focused on techniques from projective geometry and photogrammetry for understanding scene structure from multiple satellite images. Key methods involve bundle adjustment, stereo correspondence, and absolute orientation using unit quaternions. Topics cover orthorectification and DEM generation from stereo imagery, with growth data over 5 years unavailable.
Topic Hierarchy
Research Sub-Topics
Rational Function Models
Researchers develop and refine rational function models (RFMs) for geometric modeling of high-resolution satellite imagery without detailed sensor information. Studies address parameter estimation, accuracy enhancement, and integration with ground control points.
Orthorectification Algorithms
This sub-topic covers algorithms for orthorectification of satellite imagery using DEMs to correct terrain-induced distortions, including rigorous sensor models and fast approximation methods. Research evaluates computational efficiency and planimetric accuracy.
Digital Elevation Model Generation
Scientists investigate stereo photogrammetry and multi-view reconstruction from satellite imagery to generate high-resolution DEMs, focusing on matching algorithms and parallax exploitation. Topics include fusion with lidar and error propagation analysis.
Satellite Sensor Calibration
Research addresses on-orbit calibration of satellite sensors using vicarious methods, star observations, and permanent radiometric sites to maintain geometric and radiometric fidelity. It includes modeling temporal degradation and cross-calibration protocols.
Geopositioning Accuracy Assessment
This field evaluates absolute and relative geopositioning accuracy of satellite imagery through GCP-independent metrics, bundle adjustment refinement, and error budget analysis. Studies benchmark commercial satellites against national mapping standards.
Why It Matters
Satellite image processing and photogrammetry enable DEM generation and accurate geopositioning for applications in ocean engineering, water resources management, and maritime navigation. Hartley and Zisserman (2004) in "Multiple View Geometry in Computer Vision" provide techniques used in stereophotogrammetry, applied to high-resolution satellite sensors for terrain modeling. Drusch et al. (2012) describe Sentinel-2, ESA's mission capturing optical high-resolution imagery for operational services in global monitoring, supporting infrastructure projects like highway ramp expansions via integrated LiDAR and photogrammetry as noted in recent news. Tools like CNES/CARS produce digital surface models from satellite imaging for massive DSM production.
Reading Guide
Where to Start
"Multiple View Geometry in Computer Vision" by Richard Hartley, Andrew Zisserman (2004) — it covers foundational geometric principles and algebraic representations from projective geometry and photogrammetry essential for satellite image structure recovery.
Key Papers Explained
Hartley and Zisserman (2004) in "Multiple View Geometry in Computer Vision" establish multi-view geometry basics, which Triggs et al.
