Method and device for checking the visibility of a camera for surroundings of an automobile

摘要

A method for checking the visibility of a camera for surroundings of an automobile is proposed which includes receiving a camera image and a step of dividing the camera image into a plurality of partial images. A visibility value is determined based on a number of objects detected in the particular partial image. A visibility probability is subsequently determined for each of the partial images based on the blindness values and the visibility values of the particular partial images.

主权项

1. A method for checking a visibility of a camera for surroundings of an automobile, the method comprising:
receiving a camera image via a receiving interface; dividing the camera image into a plurality of partial images; determining a visibility value for each of the partial images based on a number of objects detected in the particular partial image, the visibility value being set to a predetermined value if the number of objects detected in the particular partial image exceeds a predetermined number of objects and the visibility value is reduced by a difference value if no object is detected in the particular partial image within a predetermined time interval; and determining a visibility probability for each of the partial images based on the visibility values of the particular partial images, the visibility probability specifying at what probability the visibility of the camera is present in the area of the camera image covered by the particular partial image.
