COMPARISON OF THE LINEAR AND THE NON-LINEAR BLOCK ADJUSTMENT ON SATELLITE IMAGES RESEARCH
Linear Least square method Non-Linear Least square method error equation Block adjustment Rational Function Model High-resolution Satellite images
2018/4/30
The Rational Function Model （RFM） is a non-linear model. Usually, the RFM-based satellite image block adjustment uses the Taylor series to expand error equations, and then solves the linear model. The...

2015/8/28
A private network of 133 Global Navigation Satellite Systems (GNSS) permanent sites, named ItalPoS (Italian Positioning Service) and uniformly covering the entire Italian territory, was established in...
ROBUST LEAST-SQUARES ADJUSTMENT BASED ORIENTATION AND AUTO-CALIBRATION OF WIDE-BASELINE IMAGE SEQUENCES
ADJUSTMENT BASED AUTO-CALIBRATION
2015/8/14
In this paper we propose a strategy for the orientation and auto-calibration of wide-baseline image sequences. Our
particular contribution lies in demonstrating, that by means of robust least-squares...
