The problem of determining feature correspondences
across multiple views is considered.
The term "true multi-image" matching is introduced
to describe techniques that make full and efficient
use of the geometric relationships between multiple
images and the scene. A true multi-image technique
must generalize to any number of images, be of linear
algorithmic complexity in the number of images, and
use all the images in an equal manner.
A new space-sweep approach to true multi-image matching
is presented that simultaneously determines 2D feature
correspondences and the 3D positions of feature points
in the scene.
The method is illustrated on a seven-image matching
example from the aerial image domain.
