Novel Camera Development

 

These projects involve the development of technologies for defining the next generation of digital cameras. Several different types of novel camera designs, based on ideas from PhD students, are intended to improve limitations of current cameras, such as field of view, depth of field, dynamic range. The hardware developed allowed the imaging concepts to be experimented with to improve the theoretical designs in a laboratory setting.

Split Aperture Camera Development

 

This experimental camera was developed to allow several sensors to view the same scene at the same time and from the same viewpoint. It uses a novel optical beam-splitting technique and exposure control method. The camera acquires multiple images under different exposure settings and combines them to construct a high dynamic range composite image.

This experimental camera platform was developed to experiment with a novel beam-splitter using a mirrored pyramid. This enables the image coming in from the lens to be split to multiple sensors. This experimental camera currently has three sensors but is capable of incorporating up to six individually controlled camera boards.

Nicam Development

 

Nicam (Non-frontal Imaging Camera) is able to produce 360-degree panoramic images with all objects in focus, regardless of their distance from the camera. These panoramic images are free of the seams seen in traditional large field of view panoramas. In addition, a depth estimate for each visible scene point is also determined. This camera was transferred to a start-up company for product development.

Sloped Nicam

 

This version of the Nicam camera allows the system to be completely self-contained. It includes an embeeded computer, LCD monitor, touchpad and high capacity memory for panoramic image storage.

This smaller system was designed for limited space applications and can be mounted in any orientation.  It can be interfaced and controlled by any PC. Continuous rotation of the sensor over 360 degrees provides for immersive imaging capabilities.
