3D-CITY MODEL SUPPORTING FOR CCTV MONITORING SYSTEM

Closed circuit television (CCTV) monitoring system is widely used in many important fields to monitor fixed objectives or special areas due to its reliable capability of visual remote surveillance and control. In tradition, the CCTV system design is a complex process including field survey, plan and selecting proposed cameras sites. The visual design method is introduced in CCTV system design and maintenance. This paper suggests that the visual design method should be introduced and advantages of spatial analysis and information query of GIS and 3D city model should be fully used to aid CCTV monitoring system in design and maintenance.
