Transcript

  • 1. Talal Javed QadriDuke Class of 2015
  • 2.  Worked with The Duke Imaging and Spectroscopy Program (DISP) Dr. David J Brady- Head of the program Computational optical sensors research program Affiliated with the Department of Electrical and Computer Engineering, the Fitzpatrick Institute for Photonics, and the Pratt School of Engineering at Duke University Various Projects
  • 3.  DISP developed a two gigapixel camera Used new techniques like multi-scale design using mononcentric optical designs and using microcameras as a general optical processing unit Started with initial design of 1 gigapixel and plan to eventually develop a 40 gigapixel camera Currently working on a 10 gigapixel design
  • 4.  Traditional monolithic lens designs, must increase focus and lens complexity Reduce field of view as image scale increases. Traditional electronic architectures are not designed for highly parallel streaming and analysis of large scale images. The AWARE design addresses these challenges using multiscale designs that combine a monocentric objective lens with arrays of secondary microcameras.
  • 5.  Composed of 98 smaller cameras that shoot at 14 megapixels These micro cameras rest in a football-sized sphere Pictures from the multiple cameras are then combined together in a computer connected to the sphere This „stitching‟ of images is achieved by using Gigapan software, as well as Python and Matlab programs specifically written for this purpose The final result is one highly detailed image
  • 6.  Billion pixel shots generate photos with five times as much detail as what a person with 20/20 vision can see, and produce images 30 times better than the best SLR camera available on the market Department of Defense funded the research of this device in hopes of using this technology in both aerial and land surveillance Other gigapixel cameras developed but none boast a field of view 120 degrees wide and 50 degrees tall like the Aware-2 Currently weighs a 100 pounds and shoots only in black-and-white The next 10 gigapixel camera will shoot color images and will also be lighter
  • 7.  Camera with outer covers removed
  • 8.  Exploded view of inner sphere
  • 9.  Aided in designing and building a custom transport mechanism for the camera
  • 10.  Took pictures with the camera in different locations for example in the Duke gardens Created a method for recording the exact coordinates of each picture on the Linux system of the camera‟s computer. Achieved this using a Garmin GPS receiver along with a software called “gpsd”
