  2. Problem Develop a system that can capture a video with 360o coverage and wirelessly transmit that video to a remote base station in real-time.

  3. Market Survey • There does not exist a solution which satisfies all of the following requirements: • Simultaneous 360o video capture • Wireless transmission • Real-time video feeds • Inconspicuous design • Portable design http://www.0-360.com/ http://www.immersivemedia.com/products/capture.html

  4. Deliverables • Project Plan • Design Document • Physical Prototype of system • Documents describing testing of various components and reasoning behind design decisions • Results of testing the final prototype

  5. Operating Environment Possible Uses: Endless Any environment in which a head piece of some kind is used Intended Use: Military Application Used for training exercises and combat scenarios Intended Use: Commercial Real Estate Used for virtual tours of property development

  6. Assumptions • Technology Assumptions • Commercial Cameras • Commercial Transmitters • Network Protocol • Hardware and Software Our Assumptions have remained constant throughout our research and design process.

  7. Limitations • Inconspicuous and light • Video Quality • Computing Power is minimal • Larger Bandwidth needs • Network Range

  8. Project Risks • Integration • Battery Failure • Wireless Signal Quality • Camera View Coverage

  9. Design - Conceptual

  10. Design - Actual The Pack ADC ADC ADC USB 802.11 n ADC

  11. Design – Functional Requirements • Capability of video capturing with camera • The cameras must be able to capture 360˚ horizontal coverage. • Capability to transmit video signals • System must be able to wirelessly transmit all video feeds over a range up to 50-100 meters. • Video streaming must be as close to real-time as possible. • Capability to receive and display video footage • System must include a base station with software to display the collected video feeds. • Mobility of power supply • Battery must last 4-8 hours under standard operational load. • Battery must be small and light enough to carry and wear.

  12. Design – Parts List

  13. Design – Video Capture Devices • The PC823XP Camera Array • 90-100 degrees of coverage each • Four total • Analog output • Low power consumption (3.6 watts) • 12v Li-Ion Battery Pack • Over 12 hours of battery life

  14. Design – ADC adapters • SVG3 USB Video Capture Array • Converts analog signal to digital • Outputs 30 frames per second • Output format is uncompressed AVI • Four total, one for each camera

  15. Design – Mobile Computing • BeagleBoard XM • Small form factor • 1 GHz Cortex processor • 512 MB RAM • 4 USB 2.0 interfaces • Low power consumption • BeagleJuice Battery Pack • Over 6 hours of battery life

  16. Design – Mobile Computing • Software • Dependent on operating system • Linux Ubuntu • V4L (Video for linux) • Many different options • Windows CE • Still exploring options

  17. Design – Wireless Transfer • Wireless 802.11 n Dual Band • Optimal Bandwidth of 300 Mbps • Meets the required range of 50-100 meters • USB 2.0 interface • Wireless 802.11 n Dual Band Router

  18. Display Options • For purposes of testing hardware components, we will start with a simple VLC client. • If time permits, we may build a simple client interface. However, this is not required as part of our project, and an advanced interface will likely be designed by a graduate student at a later date.

  19. Cost Analysis

  20. Testing Approach Individual • Camera FOV • Torture test of batteries • Wireless range • Video delay/synchronization Integrated • Compatibility • Data throughput • Usability

  21. Resources – Budget & Time Budget • Total initial budget: $2500 • Current cost estimate: ~$1000 • $1500 under budget if all goes according to plan Time • Individual weekly commitment is estimated to be an average 10 hours per week. • Total man hours are estimated at 1500 (300 hours per group member)

  22. Resources – Cont. Schedule We have been consistently on, or slightly ahead of schedule.

  23. Work Thus Far • Research • Hardware - complete • Software – infancy state • Hardware • Decided on parts list • Majority of hardware ordered • Software • Research state
