Abstract

In this study, by utilizing the information fusion of multi sensor data and time within the crosswalk safety Assistive gait secondary to the safety of pedestrians on the system design and system performance verification through support to. Environmental awareness, and time information in addition to leveraging the default behavior for pedestrian safety design of the secondary system performed a study on the scenario and the behavior of a system for fuzzy control was performed for each sensor data processing, median filtering, including filters processing leveraging, and was attached by the time we complete the final algorithm, the system behavior. In addition, taking advantage of the sensor measurements, so basically uncertainties and sensor results, and you want to give at least the reliability of the data fusion experiment equipment using this simple verification.

본 연구에서는 다종의 센서 데이터 및 시간 정보를 융합 활용하여 횡단보도 내에서 보행자의 안전 보행을 보조하는 시스템에 대한 설계와 시스템 성능 검증을 통한 안전 보행 보조를 지원하고자 한다. 따라서 설계한 보행자 안전 보조 시스템의 기본 동작 시나리오에 대한 연구 수행 및 시스템 동작을 위한 퍼지 제어를 수행하였고 더불어 환경 인식 및 시간 정보를 적극 활용하기 위하여 각 센서 데이터 처리를 위하여 미디언 필터링을 포함한 필터 처리를 적극 활용하였고, 이를 바탕으로 시간 정보를 첨부하여 최종적인 시스템 동작 알고리즘을 완성하였다. 추가적으로 활용하고 있는 센서들의 측정값은 기본적으로 불확실성을 내포하고 있기에 센서 결과 데이터를 융합하여 최소한의 신뢰성을 부여하고자 하였으며, 이를 간단한 실험 장비를 이용하여 검증하였다.
