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

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.
