Abstract : 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 3D 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.
