IDEA

• Create a 3D visual model of an area
• using various methods.
• Create hardware so that a person can navigate
  the area using audio
• cues as a guide.

• This hardware must perform several tasks
• a.) Visually recognize the mapped area from any
  angle.
• b.) Extract meaningful visual
  information.
• c.) Produce meaningful auditory cues for the
  user to
• respond to.

OUR TASKS
ECE 4180

• Implement the visual recognition
• Harris Corner Detection Algorithm
• On a Xilinx Spartan II FPGA
• Integrate this with a custom PCB for use in
  hardware.

ECE 4006

• Integrate four cameras with custom PCB.
• I/O Integration with sonification backend.
