Abstract

Database construction of basic elements for displaying CCTV informations(the location, direction, distance, maximum distance, Tele mode angle view, Wide mode angle view, etc.) is conducted by complete survey about CCTV information in model area. Automatic mapping algorithm is suggested to schematize and visualize it on the basic of the investigated CCTV informations. In the result, the CCTV locations in partial areas are duplicated on about 11 percents. Duplicated ones among twelve CCTVs are total five. If the redesign of CCTV location and direction by displaying the CCTV informations based on the suggested algorithm is performed, it can be used as scientific explanations.

본 연구에서는 시범지역의 CCTV 제원정보를 전수조사 하여 CCTV 위치, 주감시방향, 감시거리, 최대감시거리, Tele mode 화각, Wide mode 화각 등 CCTV 정보를 표출하기 위한 기본요소를 DB화 하였다. 조사된 CCTV제원 정보를 기초로 하여 공간정보 기반으로 도식화, 시각화 할 수 있는 자동 매핑 알고리즘 제안하였다. 알고리즘을 적용한 결과, 일부 연구지역의 CCTV 위치가 약 11% 중복된 것으로 분석되었고, CCTV 12대 가운데 중복된 CCTV는 총 5대로 도출되었다. 향후, 제시한 알고리즘을 기반으로 CCTV제원 정보를 지도에 표출하여 CCTV 위치 재설계 및 감시방향 변경 등 보다 과학적인 근거자료로 활용이 가능할 것이다.
