Multi-Sensor Triangulation

GeoEye's Multi-Sensor Triangulation (MST) system is a precise three-dimensional bundle adjustment program that models the photogrammetric projective equations of multiple imaging systems. Using both physical and stochastic mathematical models, the best regression analysis is determined for the position and attitude of all sensors providing images for the adjustment process. GeoEye's MST system yields a high degree of relative and absolute geometric accuracy by means of a simultaneous block triangulation with a sparse set of control points. Imagery is triangulated from various sensors into a single block adjustment including IKONOS®, OrbView®-3, Quickbird, and other satellite imaging sensors as well as aerial imaging platforms. The resulting solution provides a geometrically consistent model for all image sources across the project area.
