The invention relates to a method for detecting the position of an object within the interior or a vehicle equipped with a door (). The inventive method is characterized by recording a sequence of images by means of a camera () 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 () records images of the door (). The images of the door () are evaluated and the open state of the door () is established on the basis of the differential image between the closed state and the opened state.

Method and device for optically detecting the open state of a vehicle door

A source image (S) distorted by a camera lens can be transformed into a rectified target image (T), by means of a tabular imaging specification. The above occurs during read-out from the image sensor and in real-time. Each source pixel in the source image is assigned none, one or several target pixels in the target image (T). A first controller (C) controls the image sensors (B, B) accurately with tine and the image equalization and image correlation. A second controller (C) controls the first controller (C) and works in a manner temporally decoupled from the above.
