A software based method for improving accuracy of ultrasonic range finder module

摘要

This paper presents the statistics-based algorithm in order to increase the accuracy of the obstacle range measurement. This research is implemented on the concept of filtering approach and is only applied for the low-cost ultrasonic range sensor. The experiments are conducted on the HC-SR04 module and results are compared to the traditional methods. The results are shown that the accuracy of this proposed algorithm is similar to the traditional method, the measurement speed it significantly faster.
