Method and apparatus for an omni-directional video surveillance system
View Patent ↗A surveillance system uses an image from an omni-directional camera to identify objects or events of interest on which a higher-resolution camera can be trained.
1. A surveillance system comprising:
an omni-directional camera comprising an imaging unit optically coupled to a convex mirror, said omni-directional camera being configured to continuously capture an omni-directional image;
a higher-resolution camera configured to capture a higher-resolution image of a portion of said omni-directional field of view, wherein said higher-resolution camera is integrated with said omni-directional camera such that said omni-directional camera including said convex mirror and imaging unit extend from and are supported below said higher-resolution camera; and
a host computer connected to and controlling both said omni-directional camera and said higher-resolution camera;
wherein said host computer controls said higher-resolution camera based on said omni-directional image from said omni-directional camera.
2. The system of claim 1 , wherein said higher-resolution camera has a pan/tilt/zoom platform.
3. The system of claim 2 , wherein said host computer drives said pan/tilt/zoom platform.
4. The system of claim 1 , wherein said host computer comprises an image processing application that processes said omni-directional image from said omni-directional camera to identify an event or object in said omni-directional image that is of interest according to pre-defined parameters, said host computer then training said higher-resolution camera on said event or object of interest.
5. The system of claim 1 , further comprising an audio communications channel between said omni-directional camera and said host computer.
6. The system of claim 1 , wherein said omni-directional camera is mounted above said higher-resolution camera.
7. The system of claim 1 , further comprising:
a plurality of higher-resolution cameras each of which is independently controlled and oriented by said host computer; and
a user interface which simultaneously displays images output from said higher-resolution cameras along with said omni-directional image from said omni-directional camera.
8. The system of claim 1 , wherein said omni-directional camera and said higher-resolution camera are mounted co-axially.
9. The system of claim 1 , wherein said convex mirror corresponds to a hyperboloid.
