Abstract
An embodiment of the invention provides an active illumination imaging system comprising a first camera and a second camera, each having an optical axis and a field of view (FOV) characterized by a view angle in a plane that contains the optical axis and wherein the optical axes of the cameras intersect at an intersection region common to their FOVs at an angle substantially equal to half a sum of their view angles.
Claims18
An active illumination imaging system comprising:
- a light source that illuminates a scene imaged by the camera;
- and
- first and second cameras, each comprising an optical system having an optical axis and a photosensor having pixels on which the optical system images light, and a field of view (FOV) characterized by a view angle in a plane that contains the optical axis;
- wherein the optical axes of the first and a second cameras intersect at an intersection region common to their FOVs at an angle substantially equal to half a sum of their view angles to provide the imaging system with an enlarged FOV having an enlarged view angle in a plane defined by the intersecting optical axes that is substantially equal to a sum of the view angles of the cameras.
