High accuracy stereo vision camera system
First Claim
1. A stereo camera system comprising:
- (a) a rigid mounting member having a front face and a rear face, the mounting member penetrated by a plurality of apertures, the apertures extending between the front and rear faces;
(b) a plurality of lens assemblies rigidly affixed to the mounting member, the lens assemblies each comprising a lens; and
, (c) a plurality of light sensing assemblies rigidly affixed to the mounting member;
wherein each of the lenses is located to focus light through one of the apertures onto one of the light sensing arrays.

Abstract
A stereo camera system suitable for use in high performance computer vision systems has two or more electronic cameras. Each camera has an assembly comprising a light sensing array and a lens assembly which are each directly mounted to a rigid mounting member. The rigid mounting member may be, for example, a thick metal plate penetrated by a plurality of apertures which provide light paths between the lens assemblies and the light sensing arrays. Stereo camera systems according to the invention are more rugged than current stereo camera systems. Calibration is maintained for longer periods of time. Relative motion between the two or more cameras is virtually eliminated. Relative motion between the optical components of individual cameras is virtually eliminated.
