A stable block adjustment method without ground control points using bound constrained optimization
International Journal of Remote Sensing, 2022Block adjustment is a key technology for achieving large-scale accurate mapping of space via remote sensing. When block adjustment without ground control points (GCPs) is conducted, the adjustment model has large condition number of design matrix, and an

An automatic ground control point matching based on GCP chip database for remote sensing images
2009 International Conference on Image Analysis and Signal Processing, 2009With the rapid development of remote sensing technology and comprehensive applications, there are more demands on precision and efficiency for remote sensing digital orthographic maps (DOM). Selecting and positioning ground control points (GCP) is one of the most important parts of geometry correction to produce the DOM.

Assessment of UAV-photogrammetric mapping accuracy based on variation of ground control points
International Journal of Applied Earth Observation and Geoinformation, 2018Civil engineering uses digital elevation models (DEMs) and orthophotos as basic material to be able to design and execute any project. UAV photogrammetry has made it possible to obtain this type of information in an economic and practical way.
