Team:
Derrick Brazil
Benjamin 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
