  1. Capstone Project: NadeCam Team Mercury: Charles Chen, Katie Corner, Danny Costinett, bob Pomeroy, Jeries shihadeh

  2. Overview • Proposal • Hardware Block Diagram • Hardware Implementation • Software Block Diagram • Software Implementation • Feasibility and Sustainability • Safety and Compliance • Schedule and Division of Labor • Budget

  3. Proposal Camera Grenade A thrown camera Receiver station to capture images Present it in an interactive 3D view.

  4. Proposal Target size (grenade unit): golf ball to softball Receiver/Display self contained display device or possibly a receiver attached via USB to a laptop (with associated display software)

  5. Expo Deliverables • Camera • 640x480 resolution • 1 frame per second • Usable Pictures • Data Storage • Store image data on external device (SD card?) • Image Display • Proper location and orientation • “Step-Through” mode

  6. Expo Deliverables • Packaging • Contains all components • Severe impact is not a goal • Demonstration • Device can take pictures • Display images in a proper orientation • Device is moving at low velocity and acceleration

  7. Higher Deliverables-Phase 1 • Camera • Captures RGB images • Greater than 1 frame per second • 2 cameras • Depends on budget • Data Transmission • RF transmission to base station

  8. Higher Deliverables-Phase 2 • Packaging • More robust to account for impact • Demonstration • Throw ball • Use of accelerometers to return (x,y,z) position • More Cameras (Up to 6)

  9. Higher Deliverables-Phase 3 • Camera • IR capabilities • GPS unit • Ball movement after landing • In flight gyroscopic stabilization • Multi-Unit Mapping • Use GPS with Multiple Camera Units to create a more comprehensive 3D environment

  10. Block Diagram-Hardware

  11. SubSystem Implementations • Camera Unit Options • Number and Layout • 1 - 6 Standard Cameras • Two 180◦ Panoramic Cameras • Data Throughput • 8-bit Gray Scale vs. RGB Color • Resolution (640x480) • Possible Secondary IR Camera?

  12. SubSystem Implementations • Control Unit(s) • uProcessor – MSP430 or CC430? • External Transceiver – nRF24L01+ vs. CC1101

  13. SubSystem Implementations • nRF24L01+ • Higher on-air data rate (2Mbps) • Lower transmit power • CC1101 • Low sleep current (200 nA) • Higher Tx output power • Better attenuation over distance

  14. Block Diagram-Software Base Station Camera Grenade Reconstruct Image Construct 3D User Interface Camera/Accel. Control Store Image Data Power Control

  15. SubSystem Implementations Graphical Environment Google Maps API? Custom designed OpenGL environment? Images manually loaded to OpenGL environment Skybox Net. User Perspective.

  16. Feasibility • Economics • Less than $1000 (less than 2x the cost of a standard grenade) • Most parts are off the shelf and offered by multiple vendors, with the possible exception of the casing • Marketability: Military and police usage, data collection • Possible applications in scientific mapping and observation.

  17. Feasibility • Risks • Camera Functionality: • Is quality of 640x480 resolution good enough? • Number of frames per second? • Expense of Camera/Lenses • Size of Images: • Considerable amount of data throughput • Minimize via color constraints, on chip jpeg compression • Test and Pick Camera ASAP

  18. Feasibility • Risks • PCB layout mistakes: • Team reviews layout before ordering board • Enough time and budget is set aside for multiple boards • Knowledge of Packaging: • Packaging doesn't perform as well as hoped • Limited knowledge of mechanical design • Test packaging with dummy contents before full prototype build

  19. Sustainability • In general, most system parts are available from multiple vendors • caveat: although one particular camera may not be available, other comparable models are. • Minimal maintenance/support necessary out of box

  20. Safety and Compliance • Complies to necessary FCC Military and Civilian conventions, depending on model • Internal Camera Unit Voltages < 15V

  21. Schedule

  22. Schedule • CDR • Able to take and store images • Milestone 1 • Use accelerometer to determine orientation • Use software to display image(s) with correct orientation • Develop power system to power device • Milestone 2 • Packaging complete • Expo deliverable in final testing

  23. Division of Labor • Based on Background Experience Charles Chen: Image Post Processing, Accelerometer testing Danny Costinett: MSP Programming, Transceiver testing Katie Corner: Image Post Processing, Packaging Design Bob Pomeroy: PCB Design, Camera testing Jeries Shihadeh: 3D UI Environment, Camera testing
