Abstract

In this paper, we have designed and implemented a system that utilizes a radar sensor to measure distance between a sensor and objects. The sensor module creates raw data and uploads the data on the distance measuring system, which detects the presence of objects by using standard deviation and average filters. The experiment found that an algorithm using average filters measured people with error rates of up to 9.7 meters and a maximum error rate of 0.02 meters or less. While in an algorithm using standard deviations, it was found that an object is measured at an error rate of up to a maximum distance of 9.7 meters and a maximum error rate of 0.15 meters. Therefore, we have concluded that if a distance was measured by using a radar sensor, algorithms using average filters resulted in a higher accuracy than standard deviations filters.

본 논문에서는 레이더 센서를 이용하여 센서와 물체 사이의 거리를 측정하는 시스템을 설계하고 구현하였다. 센서 모듈은 센서의 원시 데이터를 거리측정 시스템에 올려주고, 거리 측정 시스템에서는 표준편차와 평균값 필터를 이용하여 객체의 유무를 탐지하였다. 실험 결과에서는 평균값 필터를 이용한 알고리즘이 최대 거리 9.7m에서 최대 오차 0.02m 이내의 오차율로 사람이 측정되는 것을 확인하였으며, 표준편차를 이용한 알고리즘에서는 최대거리 9.7m에서 최대 오차 0.15m 이내의 오차율로 사람이 측정되는 것을 확인하였다. 따라서, 레이더 센서를 이용하여 거리를 측정할 경우, 표준편차를 이용한 방법보다는 평균값 필터를 이용하는 방법이 객체 탐지의 정확도가 높음을 확인하였다.
