The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
In the description of the present application, it is to be understood that the terms "first," "second," and the like are used merely for distinguishing between the descriptions and are not intended to indicate or imply relative importance.
In the description of the present application, it is also to be noted that, unless otherwise explicitly stated or limited, the terms "disposed" and "connected" are to be interpreted broadly, for example, "connected" may be a fixed connection, a detachable connection, or an integral connection; can be mechanically or electrically connected; the connection may be direct or indirect via an intermediate medium, and may be a communication between the two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
In the prior art, when a traffic accident or other violation event occurs, vehicle information of an incident vehicle is collected by a monitoring device arranged on a monitored road section, and an incident person is confirmed by the vehicle information. The process of validation is generally: firstly, the vehicle information (such as license plate number) is confirmed, then the owner information of the troublemaking vehicle is determined through the license plate registration information, and finally the identity information of the troublemaker is checked through contacting the license plate registrant. The above-mentioned process of troublemaker confirmation is tedious, which gives the troublemaker a long time left for possible human packet dropping operation. And the difficulty factor in trying to determine the culprit is even greater in the case of an unlicensed or a vehicle that intentionally obscures the license plate.
