requirements
Requirements
  • 3600video capture of a subject’s surroundings
  • Wireless transmission of video feeds up to 100 meter
  • 4-8 hours of battery life
  • Small/portable
  • Lightweight
  • Durable
  • Inconspicuous
project plan
Project Plan
  • Research and order parts (completed)
  • Test parts as they are received
  • Create a working system with only a single stream’s throughput
  • Add the other cameras to the system until all streams are active, ensuring manageable throughput at each phase
  • Create enclosure and camera mountings once confident that the system is functioning correctly

implementation hardware
Implementation: Hardware
  • Beagleboard—Ubuntu is installed
    • Interface well understood
  • Camera—Purchased and tested
    • Future plans to develop mounting apparatus
  • Frame Grabber
    • Changed framegrabber design, learning SDK interface
    • H.264 video encoding
  • Networking
    • Network application development in progress
    • USB Dongle and Beagleboard compatible
implementation software
Implementation: Software
  • There are two different methods by which we might accomplish our streaming:
    • Hardware API and C socket code
      • Our frame grabbers come with some standard software which allows users to write C code to get frames.
      • Pros: more control over how and when packets are sent
      • Cons: more opportunity for error
    • Video4Linux software framework
      • Provides “frame grabbing” and networking functions
      • Pros: well-tested, easy integration
      • Cons: less control over traffic
testing results
Testing Results

Custom designed battery circuit may prove favorable

Beagleboard: Ubuntu, 802.11n compatibe

Cameras: 4 x 1000 viewing field

future plans
Future Plans
  • Power System Adaptation
  • Integrate the major pieces
  • Testing:
    • Network bandwidth based on distance and obstacles
    • Compression Rates
    • Evaluate battery life with entire system hooked up
tasks schedule
Tasks/Schedule

Major hardware purchased and began integrating

Testing/compatibility is greatest concern

Major Setback:

Incompatible Frame grabber New hardware decisions made
