Design of electrical pan-tilt controller based on ARM11

Abstract

This paper presented a pan-tilt control system based on ARM11 and embedded system of Linux, introduced the hardware and software design of pan-tilt controller and how it specifically worked. It mainly included the design of circuit, the design of device drivers of embedded Linux system, and the communication protocol's implementation of the pan-tilt serial interface. The system integrated the pan-tilt rotation control, the camera parameters control, video and image processing, so it not only saved hardware cost, but also improved greatly the efficiency of the system and the Performance-to-Price Ratio of products.
