A Geometry-Constrained Framework for Automatic Geometric Positioning Accuracy Assessment of Large-Scale Satellite Imagery

A geometry-constrained framework that integrates Rational Polynomial Coefficient prior constraints, coarse-to-fine registration, adaptive match-density-based block selection, hierarchical geometric verification, and a geolocation residual confidence measure into a unified automatic quality inspection pipeline is propos...

Automated On-Orbit Absolute Radiometric Calibration: A Preliminary Method and Results

On-orbit absolute radiometric calibration tracks sensor radiometric degradation and ensures accuracy for quantitative applications. Low-cost commercial satellites lack expensive on-board calibration systems, and traditional alternative methods cannot achieve automated, reliable calibration for large sensor fleets with...
