Panoramic single-aperture multi-sensor light field camera

Area of Science:

• Optics and Photonics
• Computational Imaging
• Camera Design

Background:

• Traditional cameras have limitations in capturing wide fields of view and detailed 3D information.
• Existing panoramic systems often involve complex mechanical structures or multiple lenses, leading to distortions and bulkiness.

Purpose of the Study:

• To present a new panoramic camera design utilizing a monocentric lens and an array of light field sensors.
• To demonstrate the capabilities of this system for advanced image processing tasks including refocusing and depth mapping.
• To explore a compact camera design for spherical image capture.

Main Methods:

• A monocentric lens system coupled with refractive sub-field consolidators to direct light onto adjacent CMOS sensors.
• Design and experimental testing of 160° FOV LF camera prototypes with varying sensor configurations (3-sensor and 5-sensor).
• Implementation of computational algorithms for field curvature correction, refocusing, resolution enhancement, and depth mapping.

Main Results:

• Successful capture of overlapping contiguous regions of a spherical image surface.
• Demonstration of computational image processing capabilities on captured laboratory scenes.
• Design of a compact 155° full circular field camera compatible with light field or direct sensing.

Conclusions:

• The proposed panoramic camera architecture offers a robust solution for wide-field-of-view imaging.
• The system enables advanced computational photography techniques, enhancing image quality and extracting depth information.
• The compact design shows potential for spherical imaging applications within a small form factor.
