METHOD AND DEVICE FOR DISTINGUISHING A SELF-LUMINOUS OBJECT FROM A REFLECTING OBJECT
First Claim
1. A method for distinguishing a self-luminous object from a reflecting object in a detection range of a camera of a vehicle having at least one headlight, if the object is illuminated by the headlight, the method comprising:
- receiving a relative position of the object with respect to the vehicle and a brightness value of the object from the camera;
comparing the brightness value to at least one of (i) a self-luminous value expected at the relative position and (ii) a reflection value expected at the relative position; and
classifying the object as one of (i) self-luminous, if the brightness value is within a self-luminous tolerance range about the self-luminous value and (ii) reflecting, if the brightness value is within a reflection tolerance range about the reflection value.

Abstract
A method and device for distinguishing a self-luminous object from a reflecting object in a detection range of a camera of a vehicle having at least one headlight, when the object is illuminated by the headlight, are described. The method includes a step of receiving a relative position of the object with respect to the vehicle and a brightness value of the object from the camera. Furthermore, the method includes a step of comparing the brightness value to a self-luminous value expected at the relative position and a reflection value expected at the relative position. Moreover, the method includes a step of classifying the object as self-luminous, if the brightness value is within a self-luminous tolerance range about the self-luminous value or as reflecting, if the brightness value is within a reflection tolerance range about the reflection value.

6. A device for distinguishing a self-luminous object from a reflecting object in a detection range of a camera of a vehicle having at least one headlight, if the object is illuminated by the headlight, the device comprising:
-
an apparatus configured for receiving a relative position of the object with respect to the vehicle and for receiving a brightness value of the object from the camera; an apparatus configured for comparing the brightness value to at least one of (i) a self-luminous value expected at the relative position and (ii) a reflection value expected at the relative position; and an apparatus configured for classifying the object as one of (i) self-luminous, if the brightness value is within a self-luminous tolerance range about the self-luminous value and (ii) reflecting, if the brightness value is within a reflection tolerance range about the reflection value.
