摘要

The invention relates to a system for determining whether the interior of a vehicle is occupied. The inventive device comprises image acquisition means ( 10 ) for acquiring images of an area of the vehicle interior, an image acquisition data generation unit ( 14 ) for generating image acquisition data in which every image point of a three-dimensional surface image is presented as a vector in an acquisition coordinate system of the image acquisition means, and a conversion unit ( 16 ) that converts the image acquisition data to vehicle image data. Said vehicle image data describe every image point as a vector in a coordinate system that is specific of the vehicle.
