Project Description


Summary:
Design and build an imaging system that can be mounted onto an
Unmanned Aerial Vehicle and controlled with limited user input. This includes a
high quality machine vision camera mounted on a vibration damping system, a
frame grabber board to get images from the camera, a microcontroller to control
the camera and manage storage, a power supply and a custom built frame to hold
all equipment inside the plane.

Technical Risk Assessment


Difficulty with PC104 programming and interfacing
with the frame grabber and SD card.


Mitigation: Thorough research of PC104, Seek advice from
people with PC104 experience.


Crash of UAV damages current system


Mitigation: Thorough documentation will lead to ease of
remanufacturing.


Images Blurry


Mitigation: Increase aperture and decrease shutter speed.
