Abstract

Strengthening surveillance, one of the most important factors in the crime prevention environment of cultural heritages, has difficulty in evaluating and diagnosing the site. For this reasons, surveillance enhancement has been assessed by modelling the shape of cultural heritage, topography, and trees digitally. The purpose of this study is to develop the evaluation method of crime prevention environment for cultural heritage by using the 3D visual exposure index (3DVE) which can quantitatively evaluate the surveillance enhancement in three dimensions. For the study, the evaluation factors were divided into natural, organizational, mechanical, and integrated surveillance. To conduct the analysis, the buildings, terrain, walls, and trees of the study site were modeled in three dimensions and the analysis program was developed by using the Unity 3D. Considering the working area of the person, it is possible to analyze the surveillance point by dividing it into the head and the waist position. In order to verify the feasibility of the 3DVE as the analysis program, we assessed the crime prevention environment by digitally modeling the Donam Seowon(Historic Site No. 383) located in Nonsan. As a result of the study, it was possible to figure out the problems of patrol circulation, the blind spot, and the weak point in natural, mechanical, and organizational surveillance of Donam Seowon. The results of the 3DVE were displayed in 3D drawings, so that the position and object could be identified clearly. Surveillance during the daytime is higher in the order of natural, mechanical, and organizational surveillance, while surveillance during the night is higher in the order of organizational, mechanical, and natural surveillance. The more the position of the work area becomes low, the more it is easy to be shielded, so it is necessary to evaluate the waist position. It is possible to find out and display the blind spot by calculating the surveillance range according to the specification, installation location and height of CCTV. Organizational surveillance, which has been found to be complementary to mechanical surveillance, needs to be analyzed at the vulnerable time when crime might happen. Furthermore, it is note that the analysis of integrated surveillance can be effective in examining security light, CCTV, patrol circulation, and other factors. This study was able to diagnose the crime prevention environment by simulating the actual situation. Based on this study, consecutive researches should be conducted to evaluate and compare alternatives to design the crime prevention environment.

문화재의 범죄예방환경에서 중요한 요인 중의 하나인 감시강화는 현장평가와 진단에 어려움이 있다. 이로 인해 감시강화는 문화재 형상, 지형, 수목 등을 디지털로 모델링하여 컴퓨팅 기술로 평가하는 접근이 이루어진다. 본 연구는 입체형상으로 감시강화를 정량적으로 평가할 수 있는 3차원 시각노출도 지표(3DVE, 3D Visual Exposure)를 이용하여 문화재 범죄예방환경의 평가기법을 개발하는 것을 목적으로 하였다. 연구를 위해 평가요인을 자연적 감시, 조직적 감시, 기계적 감시 그리고 통합적 감시로 세분하여 분석을 수행하였다. 분석을 위해서 건물, 지형, 담장, 수목 등의 형상을 입체적으로 모델링하였으며, Unity 3D를 이용하여 분석 프로그램을 제작하였다. 사람의 작업영역을 고려하여 머리위치와 허리위치로 구분하여 감시지점을 분석할 수 있도록 하였다. 분석 프로그램으로 3DVE의 활용 가능성을 검증하기 위해 논산에 소재한 돈암서원(사적 제383호)을 디지털로 모델링하여 범죄예방환경을 평가하였다. 연구결과 돈암서원의 자연적 감시, 기계적 감시, 조직적 감시에서 취약지점, 사각지대, 순찰동선의 문제점 등의 발견이 가능하였다. 3DVE 분석결과를 3차원 도면으로 제작함으로써 위치와 대상을 명확하게 표현할 수 있었다. 주간 감시성은 자연적 감시, 기계적 감시, 조직적 감시 순으로 높지만, 야간 감시성은 조직적 감시, 기계적 감시, 자연적 감시 순으로 높게 나타났다. 작업영역의 위치가 낮을수록 차폐되기 용이하므로, 허리위치에 대한 평가가 이루어질 필요가 있는 것으로 파악되었다. CCTV의 제원과 설치 위치, 높이에 따른 감시범위를 산출하게 됨으로써 사각지대의 발견과 표시가 가능하게 되었다. 기계적 감시의 보완효과가 있는 것으로 밝혀진 조직적 감시는 범죄취약 시간대에 분석이 요구된다. 또한 보안등, CCTV, 순찰동선 등의 설정을 검토하는데 통합적 감시도 분석이 효과적일 수 있다. 본 연구는 실제를 시뮬레이션으로 제작하여 범죄예방환경을 진단할 수 있는 성과를 거두었다. 본 연구를 기반으로 범죄예방환경설계의 대안을 평가하고 비교할 수 있는 연구가 수행되어야 한다.
