Abstract: The present invention comprises a real time image insertion system for video utilizes a three-dimensional model of at least one target area within a site for identifying the target area within an original video image of the site, and for rendering a target image and inserting it into the target area of the video image. The target area may be a real, existing surface of the site or an imaginary surface defined only in the model. The model is rendered from the position and angle of a camera that generated the video image. By using a three dimensional model of the site to generate the target image, the resulting image with the inserted target material appears more realistic.

Abstract: A system and method for calculation of the duration a target area included within an image stream utilizes a three-dimensional model of at least one target area within a site. A counter is incremented during periods, for example on a frame-by-frame basis, when the target area is included in the image stream. An occlusion parameter is calculated for adjusting the calculated duration that the target area is included within the image stream. The occlusion parameter facilitates accounting for variations in a target area obstruction and is used for making adjustments to a counter so that a count indicative of a duration reflects variations in obstructions of the target area. A foreground parameter associated with target area is calculated for adjusting the calculated duration of the target area. The foreground parameter facilitates accounting for variations in the viewability of an image included within the target area resulting from various camera zooms.
