  • 1. (AESU) Auto-Eye Surveillance UnitTeam:Derrick BrazilBenjamin Stavros
  • 2. Product Vision and Target Audience Video Surveillance in every vehicle Integrated by car manufacturers Anyone with a vehicle (expensive or inexpensive)
  • 3. Product Overview Camera unit mounted to the dome light in a vehicle Detects when the vehicle is bumped Snaps pictures when the bump occurs 360°* Camera view
  • 4. System Overview Camera system runs on the DE2 system Sensor peripherals and motor control done through the mBed system Systems communicate through a RS-232 UART connection
  • 5. DE2 Camera System Has 3 external components − 5MP Camera (TRDB-D5M) − Touchscreen (TRDB-LTM) − RS-232 UART Camera streams video to a pixel buffer stored in the SRAM Stream is read from the pixel buffer and output to the touchscreen Free mode to allow video surveillance
  • 6. Control System Overview Monitors applied force Interrupt driven to allow for low power mode (Sleep) Configures accelerometer sensitivity Logs events with timestamps Commands DE2 Camera System to take picture
  • 7. Contributions & Differentiation First in-class surveillance unit for an automobile
  • 8. Initial Product Vision Web based configuration, viewing and motor control 360° view and capture through the camera Time-stamp in picture names 3 Axis sensing Sleep mode Direction Tap Sensing SMS or Email notification
  • 9. RoadBlocks Ethernet connectivity on DE2 Web Server caching on mbed SD card file size limitation Sectioning Flash for Software and Hardware access 10 week time frame Research
  • 10. Learned Video Streaming Remote Procedure Calls XY Addressing (Pixel Buffering) Placing Hardware configuration and Software onto DE2 platform stderr can used for debug when stdout is used by the target application and how to use them both simultaneously in the NIOS software.
  • 11. What we would change Performing documentation earlier Make better use of Jira Make initial product scope based on existing knowledge and then move to exploration of new features and modules Dedicate a set amount of time each day to accomplishing project objectives
  • 12. Future Work DMA to read the data from the pixel buffer and write it to the RAM and vice versa Web server for configuration 360º rotation and control of servo motor
