VERFAHREN UND VORRICHTUNG ZUR OPTISCHEN ERKENNUNG DES ÖFFNUNGSZUSTANDES EINER FAHRZEUGTÜR

摘要

The invention relates to a method for detecting the position of an object within the interior or a vehicle equipped with a door ( 4 ). The inventive method is characterized by recording a sequence of images by means of a camera ( 2 ) and calculating the actual position of the object by electronically evaluating the images of the sequence of images, and generating a differential image by comparing an actual recorded image with a previously stored image. The position of the object is calculated on the basis of the differential image. To achieve this, the camera ( 2 ) records images of the door ( 4 ). The images of the door ( 4 ) are evaluated and the open state of the door ( 4 ) is established on the basis of the differential image between the closed state and the opened state.
