Abstract

The invention relates to a camera system, especially for photogrammetric applications. The camera system contains at least two first cameras (1, 2), which are inclined towards each other so that the optical axes (7, 8) of the first cameras (1, 2) intersect at a common point of intersection (5). The camera system also has at least two second cameras (10, 11) which are located at a distance from the first cameras (1, 2), in the viewing direction of the first cameras (1, 2). The inclination of the optical axes (7, 8) of the first cameras (1, 2) towards each other provides an area (b) in which the envelope that surrounds the acceptance cones of the first cameras (1, 2) has an essentially constant diameter. The second cameras (10, 11) are located in this area (b) so that the second cameras (10, 11) avoid truncating the projection of the visual fields of the first cameras (1, 2). The first cameras are preferably panchromatic and the second cameras polychromatic.
