Image processing system for a vehicle
First Claim
1. A method for the operation of an image processing system for a vehicle, where, using at least one image sensor, information about the surroundings can be detected, and where the detected information about the surroundings is evaluated with a computer unit in order to recognize the presence of traffic participants, wherein the direction of looking of one or several recognized traffic participants is detected.

Abstract
In order to assist the driver, future vehicles are being equipped with systems for detecting the surroundings. Such systems serve to provide the driver with advance warning about possible collisions with other participants in traffic, for example, pedestrians. Here, the detection of the information about the surroundings is done, among others, using image sensors and their evaluation via an image processing unit. The evaluation of image data is limited to simple geometric and dynamic models which describe the behavior of participants in traffic. Therefore, an image-processing system is proposed which takes into consideration the attention of other participants in traffic. Especially here, the direction of looking of recognized participants in traffic is detected and, based on the detected direction of looking, a probability is determined for evaluating the risk of collision with other participants in traffic. In case the collision risk exceeds a certain determined threshold value, measures are initiated for avoiding a collision.
