Ultrasonic Positioning In Three-dimensional Space

摘要：

In this paper, an improved measurement method of ultrasonic is researched in the field of the dynamic three-dimensional positioning system, which improves greatly the accuracy and performance of measurement system. Special high-frequency timer chip and automatic gain control module are adopted into the system to further improve the accuracy of received signals. Real-time measurement of the threedimensional position by the above method is tested by the virtual computer mouse. The result shows that the method is more accurate and meets the requirement of human-computer interaction system.
