Method and device for determining the three-dimension position of passengers of a motor car
First Claim
1. A method for determining the three-dimensional position of vehicle passengers which comprises the following steps:
- observing the vehicle passengers by means of at least two cameras (1, 2, 1′
, 2′
) which are disposed in such a way that they can operate in non-stereo mode;
extracting appropriate characteristics from the recorded video data of the vehicle passengers;
initializing a tracking method by means of a head model;
verifying the extracted characteristics by means of pattern recognition; and
tracking the verified characteristics by means of the head model.

Abstract
The invention relates to a method for determining a three-dimensional position of passengers of a motor vehicle. The inventive method consists in observing the passengers of the vehicle with the aid of at least two cameras (1, 2, 1′, 2′) which are disposed in such a way that they can operate in non-stereo mode, extracting the appropriate characteristics of the passengers from video data, initialising tracking by means of a head model, verifying said extracted characteristics by pattern recognition and in tracking said verified characteristics by means of said head model. The inventive device based on a store controller which is used for carrying out said method is also disclosed.
