• Ultrasonic Sensors
• Cameras
• Camera Lighting Control
• Conclusion

Overview
• Project might be incorporated into Senior Design (Automated Car that uses cameras to detect obstacles)
• Importance of the car – Reduces the number of accidents that are caused by humans (especially women)
• Major companies are just beginning to implement these types of control systems
• Block Diagram
Overall Block Diagram
Ultrasonic Sensors
• Send out a sound wave• Receiver waits for sound wave deflection• Cylindrical objects – shorter detection
distance
Cameras
• Take Pictures
• Filter out colors
• Triangulate two pictures for distance measurement
• Attempt to avoid glare problems
Purpose of the Lighting Control
• Picture Consistency
• No blacked out or too bright images
• Possible Glare Reduction
Theory
• The shutter speed determines how much light enters the lens
• If the time increases more light hits sensor
• If the time decreases less light hits the sensor

Conclusion
• Cameras today do not implement this type of control system.
• Therefore, Not sure if it is possible to implement.
• The car that we are designing might implement this design, but it might not.
• Definitely is better for multiple shot cameras.
