Title:
ARRANGEMENT OF MULTIPLE CAMERAS IN A MULTI-DIRECTIONAL STEREO CAMERA SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/104989
Kind Code:
A4
Abstract:
Arrangement of cameras (3) includes at least three camera nests (2) in which the cameras (3) are arranged in such a way that the axis (2) of the field of vision of each camera (3) in the camera nest (2) lies in a common plane (p) of the camera nest (2) and such axes (2) of the fields of vision intersect in a common point which forms the center of the camera nest (2). The normal lines (n) running from each centers of the camera nests (2) intersect in a common point which is the center of the holder's body (1 ). In planar arrangement the holder's body (1) includes a carrier construction in shape of a regular horizontal polygon, whereby in each cusp of the regular polygon there is a camera nest (2) whose number of cameras (3) is chosen in such a way that the camera nest (3) offers a quality 360° view in the vertical direction. In a spatial arrangement the holder's body (1) includes a carrier construction in shape of a regular polyhedron, whereby in each cusp of the regular polyhedron there is a camera nest (2) whose number of cameras is a multiple of the number of edges of the polyhedron's cusp.

AMENDED CLAIMS

received by the International Bureau on 12.05.2020

1. An arrangement of multiple cameras into a multidirectional stereo camera system, where the individual cameras (3) are positioned immovably mutually against each other in such a way that a sum of fields of vision of the cameras (3) includes a whole surrounding space, whereby at least some points of the space lie simultaneously in the field of vision of two cameras (3), it includes at least three camera nests (2) in which the cameras (3) are placed in such a way that an axis (2) of the field of vision of each camera (3) in the camera nest (2) lies in a common surface (p) of the camera nest (2), and these axes (a) of the fields of vision intersect in a common point which forms a center of the camera nest characterized by the fact, that

normal lines (n) running from all centers of the camera nests (2) intersect in the common point, the intersection point of the normal lines (n) running from the centers of the camera nests (2) lies in the center of a holder’s body (1) which carries the camera nests (2)

and the holder’s body (1) is spatial.

2. The arrangement of multiple cameras into the multidirectional stereo camera system according to the claim 1 , characterized by the fact, that the axes (a) of vision of each camera (3) in the camera nest (2) form a tangent to the holder’s body (1) and the common surface of the camera nest (2) is a plane.

3. The arrangement of multiple cameras into the multidirectional stereo camera system according to the claim 1 , characterized by the fact, that the axes (2) of the field of vision of each camera (3) in the camera nest (2) deviate from the tangent to the holder’s body (1) by up to 60°, whereby the cameras (3) are directed outside the body (1 ).
