Abstract

A chassis assembly is disclosed including a chassis and plurality of image sensors fixedly mounted to the chassis. The number of image sensors may vary, but in one example, there are three image sensors, arranged in an equilateral triangle within the chassis. Each image sensor includes a camera, which may be a video camera, and a catadioptric mirror. The mirror in each image sensor is fixedly mounted with respect to the camera via a stem and a collar for mounting the mirror to the chassis.

Claims

1. A system for capturing stereoscopic image data, comprising:

three or more image sensors operating in combination with each other to capture left and right views of a panorama for generating a stereoscopic panoramic view.

2. The system for capturing stereoscopic image data as recited in claim 1, wherein the three or more image sensors capture a panorama of 360°

.

3. The system for capturing stereoscopic image data as recited in claim 1, an image sensor of the three or more image sensors comprising a catadioptric convex mirror and a camera receiving catadioptric images from the mirror.

4. The system for capturing stereoscopic image data as recited in claim 3, the catadioptric convex mirror comprising an equi-angular surface.

5. The system for capturing stereoscopic image data as recited in claim 1, further comprising a chassis for supporting the three or more image sensors in a fixed relation to each other.

6. The system for capturing stereoscopic image data as recited in claim 5, wherein the three or more image sensors comprises three image sensors, the chassis supporting the optical axes of the three image sensors in an equilateral triangle.

7. The system for capturing stereoscopic image data as recited in claim 5, further comprising a stem and a collar for fixing the mirror with respect to the chassis.

8. The system for capturing stereoscopic image data as recited in claim 1, wherein the three or more image sensors comprise between four and six image sensors.

9. The system for capturing stereoscopic image data as recited in claim 1, further comprising a computing device having a processor for processing image data captured by the three or more image sensors.

10. The system for capturing stereoscopic image data as recited in claim 9, wherein the computing system communicates with the three or more image sensors by one of a wired or wireless communication.

11. A catadioptric chassis assembly for capturing stereoscopic image data, comprising:

a chassis including three receptacles; and

three image sensors, one fixedly mounted in each receptacle in the chassis, the three image sensors working together to capture image data used to provide a stereoscopic view of the panorama.

12. The catadioptric chassis assembly recited in claim 11, the three receptacles supporting the three image sensors with optical axes of the image sensors together defining an equilateral triangle.

13. The catadioptric chassis assembly recited in claim 11, wherein the three or more image sensors capture a panorama of 360°

.

14. The catadioptric chassis assembly recited in claim 11, wherein each image sensor comprises:

a camera;

a convex mirror for directing an image of the captured panorama into the camera; and

a step for supporting the convex mirror in a fixed position with respect to the camera.

15. The catadioptric chassis assembly recited in claim 11, the catadioptric convex mirror comprising an equi-angular surface.

16. The catadioptric chassis assembly recited in claim 11, wherein each image sensor captures one of still images and video images.

17. A catadioptric assembly for capturing stereoscopic image data, comprising:

three image sensors fixedly mounted to each other and working together to capture image data used to provide a stereoscopic view of the panorama, each image sensor of the three image sensors including;

a camera for capturing images, and

a catadioptric mirror for directing images from 360°

around the catadioptric mirror down into the camera.

18. A catadioptric assembly as recited in claim 17, the three image sensors comprising:

a first image sensor for capturing;

a) a view of a first portion of the panorama used for the left perspective in the stereoscopic view of the first portion, and b) a view of a second portion of the panorama used for the right perspective in the stereoscopic view of the second portion;

a second image sensor for capturing;

a) a view of the first portion of the panorama used for the right perspective in the stereoscopic view of the first portion, and b) a view of a third portion of the panorama used for the left perspective in the stereoscopic view of the third portion; and

a third image sensor for capturing;

a) a view of the third portion of the panorama used for the right perspective in the stereoscopic view of the third portion, and b) a view of a second portion of the panorama used for the left perspective in the stereoscopic view of the second portion.

19. A catadioptric assembly as recited in claim 18, the first image sensor not used to capture images from the third portion, the second image sensor not used to capture images of the second portion, and the third image sensor not used to capture images of the first portion.

20. A catadioptric assembly as recited in claim 17, wherein the surface of the mirrors used in the first, second and third images sensors is equi-angular.
