Abstract

The research established the mathematical model of camera monitoring region on the basis of the camera parameters and formation process of the flashlight aperture. First，the coordinates of the visualization domain center point were solved by the Janus algorithm using the camera parameters. And the regular dodecagon generating a circle algorithm was used to calculate the boundary points of the plane containing the visualization domain center point and perpendiculars to the center sight line. Then the boundary points corresponding to the camera monitoring region was extracted by Janus algorithm again. Finally，the algorithm was implemented on the basis of DEM of Three Bridge Town in Linan and the synchronization tracking tests showed that this algorithm could display the camera monitoring region synchronously on the DEM and achieve the information linkage between the video surveillance and GIS technology.［Ch，6 fig. 14 ref.］
