However, this method requires installation of ac power supply facilities, which is costly; still need often wash the camera, otherwise the camera is sheltered from by the dust easily, causes the license plate recognition accuracy to reduce.

Therefore, there is a need for improvements in the prior art.

The detection module 132 is configured to determine whether the user vehicle 300 changes from a traveling state to a parked state based on a change in the vehicle position parameter, and generate a vehicle parking signal if the user vehicle 300 changes from the traveling state to the parked state, e.g., the speed of the user vehicle 300 changes from non-zero to zero, the vehicle parking signal including a parking time and a parking position at which the user vehicle 300 changes from the traveling state to the parked state.

In the present application, matching the vehicle entering signal with the vehicle parking signal means matching feature information that is commonly included in the vehicle entering signal and the vehicle parking signal and can reflect that the user vehicle enters the parking space, where the feature information includes a plurality of feature parameters.

The characteristic parameters that are commonly included in the vehicle entrance signal and the vehicle parking signal and that reflect the entrance of the user vehicle into the parking space include a position P of parking, a time T of parking, a weight W, a length L, a height H, and the like, and these characteristic parameters may be included in or derived based on the vehicle entrance signal or the vehicle parking signal. Wherein the position of the parking space and the parking position correspond to a characteristic parameter P; the vehicle driving time and the vehicle stopping time correspond to the characteristic parameter T; the vehicle-entry signal may include a weight of the vehicle entering the parking space, and the vehicle-parking signal may include a weight of the user vehicle, which correspond to the characteristic parameter W; the vehicle entrance signal may include a length of the vehicle entering the parking space, and the vehicle parking signal may include a length of the user vehicle, which correspond to the characteristic parameter L; the vehicle entrance signal may include a height of the vehicle entering the parking space, and the vehicle parking signal may include a height of the user vehicle, which collectively correspond to the characteristic parameter H. Therefore, the matching of the characteristic parameters can be performed by calculating the difference between two or more characteristic parameters included in the vehicle entrance signal and the corresponding characteristic parameters included in the vehicle stop signal, and substituting the difference between these characteristic parameters into the metric function to calculate the metric value reflecting the degree of similarity of the characteristic information. Here, the metric function may be any linear or non-linear function that can reflect the degree of similarity of the feature information.

It will be understood by those skilled in the art that since the vehicle entrance signal and the vehicle parking signal are derived from different sources and are independent of each other, when the similarity degree of the characteristic information included in the two signals reaches a preset threshold, the two signals are considered to be directed to the fact that the user vehicle 300 enters the parking space 200. It is understood that the more sources of information that can reflect that user vehicle 300 enters parking space 200, that is, the more vehicle detection device 120 associated with parking space 200 or the more number of in-vehicle terminals 130 that user vehicle 300 is provided with, the higher the accuracy of determining whether user vehicle 300 enters parking space 200. It is understood that the more contents of the characteristic information that can reflect the user vehicle entering the parking space that the parking space management server 110 receives from the vehicle detection device 120 and the in-vehicle terminal 130, the higher the accuracy of determining whether the user vehicle 300 enters the parking space 200.

In some embodiments, the determination module 113 includes a distance difference calculation module 1132, a time difference calculation module 1133, and a vehicle entrance determination module 1134, as shown in fig. 6. Alternatively, the determination module 113 may further include a parking space position determination module 1131 configured to determine the position of the parking space, for example, it may store a correspondence table of the transmission address of the vehicle detection apparatus 120 and the position of the parking space in advance, and then determine the position of the parking space associated with the vehicle detection apparatus 120 according to the transmission address of the vehicle detection apparatus 120, or store a correspondence table of the parking space identifier and the position of the parking space in advance, and then determine the position of the parking space using the parking space identifier included in the vehicle entrance signal.
