Abstract
For several useful tasks in photogrammetry and in model-based
vision, noniterative methods that require only the inversion of systems
of linear equations are developed. The methods are based on the theory
of projective invariants. The tasks addressed are resection,
intersection, and transfer, or model matching (with or without ground
control points). The following kinds of transfer are examined: (a)
coplanar object points (transfer to image 2 done using four reference
points in image 1); (b) stereo camera system (transfer to stereo camera
pair 2 done using four reference points in stereo pair 1); (c) general
multicamera configuration (transfer of a ninth point to image 3 done
using eight tie points in images 1 and 2)
