Abstract

A panoptic camera system that can be used to capture all the light from a hemisphere viewing angle is disclosed. The panoptic camera comprises a main reflecting mirror that reflects light from an entire hemisphere onto an image capture mechanism. The main reflecting mirror consists of a paraboloid shape with a dimple on an apex. The surface area around the dimple allows the main reflector to capture light from behind an image capture mechanism or a second reflector. When two panoptic camera systems that capture the light from an entire hemisphere are placed back to back, a camera system that “sees” light from all directions is created. A stereo vision panoramic camera system is also disclosed. The stereo vision panoramic camera system comprises two panoramic camera systems that are separated by a known distance. The two panoramic camera systems are each placed in a “blind spot” of the other panoramic camera system. By using the different images generated by the two panoramic camera systems and the known distance between the two panoramic camera systems, the range to objects within the panoramic images can be determined.

Claims

1. A camera apparatus, said camera apparatus comprising:

an image capture mechanism; and

a main reflector, said main reflector reflecting light from a full hemisphere view onto said image capture mechanism;

wherein said main reflector comprises a cylindrically symmetrical shape of a parabola segment rotated about an axis, said parabola segment comprising a vertex, a first side of said parabola segmenty, and a second side of said parabola segment shorter than said first side and adjacent to said axis.

2. The apparatus as claimed in claim 1 further comprising:

a second reflector, said second reflector positioned such that said light is reflected from said main reflector onto said second reflector and then from said second reflector onto said image capture mechanism.

3. The apparatus as claimed in claim 1 wherein said light passes through a set of lenses before landing on said image capture mechanism.

4. A camera apparatus, said camera apparatus comprising:

an image capture mechanism; and

a main reflector, said main reflector comprising a paraboloid shape with a dimple on an apex;

wherein said main reflector comprises a cylindrically symmetrical shape of a parabola segment rotated about an axis, said parabola segment comprising a vertex, a first side of said parabola segment, and a second side of said parabola segment shorter than said first side and adjacent to said axis.

5. The apparatus as claimed in claim 4 further comprising:

a second reflector, said second reflector positioned such that said light is reflected from said main reflector onto said second reflector and then from said second reflector onto said image capture mechanism.

6. The apparatus as claimed in claim 5 wherein said light passes through a set of lenses before landing on said image capture mechanism.
