Method for detecting objects on a parking area
First Claim
1. A method for detecting objects on a parking area for vehicles with the aid of image processing of images from at least two imaging sensors, wherein detection ranges of the imaging sensors overlap at least partially, the method comprising:
- determining which of the imaging sensors has an image quality limited by environmental conditions, the determining being based on;
(i) a position and orientation of each of the imaging sensors, (ii) a date, and (iii) a time;
processing images from the imaging sensors including less strongly weighting images of the determined imaging sensor of the imaging sensors whose image quality is limited by environmental conditions than images of an imaging sensor of the imaging sensors whose image quality is not limited by environmental conditions; and
detecting objects on the parking area based on the processed images.

Abstract
A method for detecting objects on a parking area for vehicles with the aid of image processing of images from at least two imaging sensors, detection ranges of the imaging sensors overlapping at least partially. The images of an imaging sensor whose image quality is limited by environmental conditions are weighted less strongly for the detection of objects on the parking area during image processing than images of an imaging sensor whose image quality is not limited by environmental conditions. A processing unit, a program, and an overall system for carrying out the method are also described.
