The latest vehicle yields a superior safety and reduction of driving burden by monitoring the driving state of vehicle and its environment with various sensors. To detect other vehicles and objects of the rear left and right-side blind spot area of driver, provide the information about a existence of objects inside the blind spot, and give a signal to avoid collision, this study proposes the intelligent outside rear-view mirror system. This task has substantially complicated several factors. For example, the size, geometry and features of the various vehicles which might enter the monitored zone is varied widely and therefore present various reflective characteristics. This study proposes the optimal specification and configuration of optical system and IR array sensor of blind spot detection system, and shows the results of the performance evaluation of developed system.

Ubiquitous computing is a novel paradigm that is rapidly gaining in the scenario of wireless communications and telecommunications for realizing smart world. As rapid development of sensor technology, smart sensor system becomes more popular in automobile or vehicle. In this study, a new vehicle detection mechanism in real-time for blind spot area is proposed based on imaging sensors. To determine the position of other vehicles on the road is important for operation of driver assistance systems (DASs) to increase driving safety. As the result, blind spot detection of vehicles is addressed using an automobile detection algorithm for blind spots. The proposed vehicle verification utilizes the height and angle of a rear-looking vehicle mounted camera. Candidate vehicle information is extracted using adaptive shadow detection based on brightness values of an image of a vehicle area. The vehicle is verified using a training set with Haar-like features of candidate vehicles. Using these processes, moving vehicles can be detected in blind spots. The detection ratio of true vehicles was 91.1% in blind spots based on various experimental results.

케이블로 상부구조가 지지되는 특수교량의 경우 특수한 장비와 인력이 없이는 접근이 어려운 사각지대가 다수 존재하고 있어, 안전점검에 많은 애로사항이 발생하고 있는 것이 현실이다. 본 연구에서는 사장교와 현수교 등 케이블지지교량의 안전점검 사각지대를 검토하고, 드론을 활용하여 사각지대를 해소할 수 있는 방안을 연구하는 것이 목적이다. 이를 위해 해상에 위치한 사장교를 드론을 활용하여 케이블과 보강형 그리고 주탑을 점검하였다. 본 연구를 통해 드론을 활용하여 점검자의 접근이 어려운 특수교량의 외부 안전점검이 가능함을 확인하였다. 특히 특수교량의 점검사각지대인 주탑 외부 상태 및 손상 확인을 위한 드론 점검은 매우 효과적인 안전점검 방법이다.

To detect other vehicles and objects of the rear left and right-side blind spot area of driver, provide the information about a existence of objects inside the blind spot, and give a signal to avoid collision, this study proposes the intelligent outside rear-view mirror system. This study proposes SILS system with PreScan and Matlab/Simulink to verify practical applicability of developed BSDS. PreScan yields realistic driving environments and road conditions and vehicle model dynamics and collision warning is controlled by Matlab/Simulink.

Recently, in order to reduce traffic accident related fatalities, increasing number of studies are conducted regarding the vehicle safety enhancement devices. But very few studies about test procedures and requirements for vehicle safety systems are being carried out. Since BSD, as one of the most important safety features, is installed on a new vehicle, its performance test method has to be evaluated. Independent factors irrelevant to the device types including collision position, vehicle speed and closing speed are used to calculate test distance away from the current vehicle. Effect of roadway geometry as radius of curvature is introduced to propose possible misjudgement of following vehicle as adjacent one. The study results would be utilized to enhance the test procedure of BSD performance.

정부의 포용적 복지국가 실현 정책에 따라 복지관련 서비스가 다양해지고 복지 급여의 수급 대상자의 범위가 확대됨에 따라 사각지대 관리의 중요성이 높아지고 있다. 이에 따라 사회안전망의 확충이 주요 관심사로 제시되고 있으며 복지위기의 사각지대 관리를 위하여 저소득층 소득과 자립을 지원하고 빈곤·위기 가구를 적극적으로 발굴 및 지원하는 내용의 사회안전망 관리가 필요하다. 본 논문에서는 복지사각지대 관리를 위하여 사각지대 관련 다양한 문제점을 검토하고 사각지대의 범위를 고려하여 블록체인 기반 분산 ID의 적용가능성과 분산 ID(Decentralized Identifier) 기술의 단계별 적용 가능성을 제안하였다.

This paper contributes to development of a new method for detecting rear-side vehicles and estimating the positions for blind spot region or providing the lane change information by using vision systems. Because the real image acquired during car driving has a lot of information including the target vehicle and background image as well as the noises such as lighting and shading, it is hard to extract only the target vehicle against the background image with satisfied robustness. In this paper, the target vehicle has been detected by repetitive image processing such as sobel and morphological operations and a Kalman filter has been also designed to cancel the background image and prevent the misreading of the target image. The proposed method can get faster image processing and more robustness rather than the previous researches. Various experiments were performed on the highway driving situations to evaluate the performance of the proposed algorithm.
