Abstract
A method for detecting an object crossing event at a predetermined first line in a scene captured by a motion video camera is disclosed. The method comprises determining from images of the scene captured by the motion video camera if an object image crosses the predetermined first line, calculating a size value relating to the size of the object image crossing the predetermined first line, setting a line distance value to a value calculated from the distance between a contact point of the object with the predetermined first line and a nearby point on a predetermined second line, and generating an object crossing event signal if a relation between the calculated size value and the line distance is within a predetermined range.
