<p>A modeling method of three-dimensional spatial information based on a two-dimensional floor plan and a video surveillance system using a three-dimensional spatial model according to an embodiment of the present invention can model three-dimensional information by using a two-dimensional floor plan and identify a position of a camera and a surveillance region through a simulation so that position correction to an accurate position is possible. In addition, three-dimensional spatial information modeling is performed based on two-dimensional information such as an architectural plan, and a surveillance camera is disposed through visual identification, then the two-dimensional floor plan, which includes a type and position information of a corresponding camera, is provided thus improving convenience and accuracy upon construction. Also, an image cut, which is virtually photographed by a camera positioned at a three-dimensional spatial information modeling, or an image cut of a camera position in the 3-dimensional space, or information related to a camera construction is added to a two-dimensional floor plan for the construction so that errors are minimized upon construction.</p> |
