Abstract :
This paper proposes a novel method to improve the accuracy of ultrasonic absolute localization. The characteristic and problem of ultrasonic absolute localization are analyzed and the insufficiency in existing methods is pointed out. Aiming at these questions, the special fusion method for redundancy ultrasonic information (SFMRUI) has been proposed. SFMRUI can well eliminate the error about times of flight (TOF) and can accurately calculate the wave lagging error. Moreover it can give an estimation of the measuring accuracy. Finally the experiment and the simulation have been performed, the experiment and the simulation results proved the SFMRUI law is effective and it can greatly improve the absolute localization accuracy.
