  1. Conference Room Laser Pointer SystemFinal Design Report Anna Goncharova Brent Hoover Alex Mendes

  2. Presentation Outline • Project Concept • Hardware component • Image processing component • Future Work

  3. Project Concept • “In large conference room presentations when the slides are shown on multiple screens, there is no good solution for pointing a laser at one screen and having it shown on the other(s). This project will use camera(s) to monitor large conference projection screens and look for a laser pointer. When a laser is determined, another laser will be turned on to the other screen and project the pointer to the same spot on the screen.”

  4. General System

  5. Last Year Touch screen used instead

  6. Hardware • Goal: to direct the secondary laser to the appropriate location and to turn the secondary laser on/off as needed • Main components: webcam, servo motors, pan and tilt system, relay

  7. Hardware Relay

  8. Hardware Components Pan and tilt system Servo motor Controller Relay

  9. Software • Goal: to detect the primary laser and send its (x,y) coordinates to the servo motors • C++ code and OpenCV (open source image processing library) used

  10. Testing and Evaluation • We tested our progress by demonstrations • Our progress could be evaluated by how accurately and quickly the system worked Demonstration

  11. Future Work • Improve system calibration • Improve speed of relay switching while maintaining resistance to noise • Improve system housing • Improve C++ code to make it more robust
