Abstract :
In this paper, an inexpensive sensors-based position detector on pan-tilt system has been developed, and a novel pan-tilt system attitude parameters calculation method is provided. The system consists of a low-cost dual-axial accelerometer, a low-cost tri-axis magnetic sensor and a microprocessor to detect the position of pan-tilt in real-time. Compensation techniques are shown to offset for temperature effects and nearby ferrous material disturbances. The reliability and performance of the designed system have also been verified through real experiments which show that the new system has great potential in applications.
