VERFAHREN UND VORRICHTUNG ZUR ERMITTLUNG DER POSITION EINES OBJEKTES INNERHALB EINER SZENE

摘要

The invention relates to a method and device for determining the position of an object within a given area. The position of an object within a given area, especially the head of a passenger seated in a vehicle, is determined using a differential image which is produced from two images taken one after the other by a camera and in which only the contour of moving objects appear, whereby the contours of the differential images are used to calculate the position.
