A camera modeling system. The camera modeling system includes: a vanishing point detecting module configured to detect, from at least one reference detection object existing in a detection region, a first vanishing point and a second vanishing point; a view mode determining module configured to determine a camera view mode on the basis of a distance from a first position in the detection region to the first vanishing point and a distance from the first position to the second vanishing point; and a camera modeling module configured to select a camera modeling mode corresponding to the determined camera view mode and perform camera modeling through the selected camera modeling mode.
