Abstract

There is disclosed a method and system for detecting the presence of an object within a restricted zone that comprises of a computerized means (1), an image capturing means (2) having connection to the computerized means and adapted to capture image pair, a software resides in the memory device that once executed, performs intrusion analysis based on images captured by the image capturing means; characterized in that the intrusion analysis is performed by processing the captured image pair to obtain parallax information (10), estimating the position of an object in the image in a depth plane (11), and determining whether the object position collides within the restricted zone (12). If the object position collided within the restrictive zone, entry to the restrictive zone is considered as intrusion. The parallax information is calculated by first shifting (20) one of the image pair toward the other such that the images are overlapping and thereafter recording the number (21) of the overlapping pixels. The shift that has the most overlapping pixels is selected to be the selected parallax value and will be compared against values in the parallax checklist and if the selected parallax value falls within the values in the restricted zone, it is an intrusion into the restrictive zone.
