Trip-line detection is one of the very important research topics of intelligent monitoring category.This paper will present a trip-line detection system.In our trip line detection algorithm, Gauss model is used to model background, background differencing is used to detect object.Scanning the set of points on the line, if object is cross the line, for doubledirection trip-line detection system directly alerts, but for single-direction trip-line detection, the moving direction of the object must be analyzed first.If the moving direction of the object violate passing rule, system directly alerts.
