Raspberry Piを用いた小型超音波センサシステムの実現

―Julia言語によるMUSIC法アルゴリズムの高速化―

抄録

The goal of this study is to develop an ultrasonic sensor system using MUSIC method which consists of an ultrasonic phased array transmitter and a microphone array receiver that we proposed, which can be mounted on a small mobile robot. Therefore, in this study, we aim to build a sensor system using the Raspberry Pi 4B, the algorithm for the MUSIC method is implemented using the Julia language, which is characterized by its fast execution speed. In this paper, we evaluate the processing time of the MUSIC method and confirm the accuracy of object position estimation on the faster processing system developed. As a result, we confirmed that it is possible to estimate the object position with high resolution and fast processing time.
