Abstract
Nowadays, tilt and pan cameras have been increasingly implemented in robotic and machine vision applications. In this project, a tilt and pan system was developed based on two servo motors. One of the servo motors is used to perform the tilt motion while the other servo motor is used for the pan motion. The thumb joystick and computer is used to control the motion of the tilt and pan. In this project, there are two microcontrollers to be used. One of the microcontrollers is responsible to receive the signals from the joystick and computer. After that, the signals are transmitted to another microcontroller located at camera location. The microcontroller located at the camera location is connected with two servo motors to perform tilt and pan motion. The communications between the microcontrollers is implemented through a pair of wireless RF transmitter and receiver. The camera used in this project is a wireless camera comes along with the receiver. The wireless camera is mounted on the servo motor while the receiver is connected to the Altera DE2-70 board. The Altera DE2-70 board is used to acquire and display the images on monitor through VGA interface. The NiosII processor from Altera DE2-70 board is used to capture the images and enhance the contrast of the images. At the end, the image is saved as a bitmap file in the computer.
In conclusion, the tilt and pan system was successfully developed and can be applied in
robotic or machine vision application.
