METHOD FOR DETERMINING THE OCCUPANCY OF A PARKING AREA WITH AT LEAST ONE ENTRANCE AND EXIT

Document Type and Number:

WIPO Patent Application WO/2013/083109

Kind Code:

A8

Abstract:

The invention relates to a method for determining the occupancy of a parking area with at least one entrance and exit (11, 12), in particular for determining the occupancy of a parking area with marked parking spaces for motor vehicles on highways (9) and motorways. According to the invention, image data of a vehicle driving into the parking area is detected by a sensor unit (4), said image data reproducing the outer appearance of the vehicle. Characteristic features of the entering vehicle are determined from the obtained image data by means of a feature extraction process and stored in a memory unit together with the time at which the vehicle entered the parking area. Image data is likewise detected for a vehicle exiting the parking area by means of a sensor unit (4), and characteristic features are extracted. The exiting vehicle is identified by comparing the characteristic features of the exiting vehicle with the characteristic features of all the vehicles available in the memory unit. In the event of a match, i.e. a clear identification of the vehicle, the vehicle is removed from the memory unit. If the exiting vehicle cannot be clearly identified, said exiting vehicle is no longer taken into consideration. Furthermore, the parking time of each vehicle which can be found in the memory unit is continuously calculated. If the calculated parking time of a vehicle exceeds a specified parking time, said vehicle is removed from the memory unit. The occupancy of the parking area is calculated by adding the vehicles stored in the memory unit.
