Path restoration method and system in portal detection form

Abstract

The invention discloses a portal detection form path restoration method and system, and the method comprises the following steps: obtaining portal data of a vehicle, the portal data comprises a plurality of groups of passed portal data, and the portal data comprises a front portal and a rear portal adjacent to the front portal; mapping front portal frames, wherein the portal of the road on the other side is arranged in cooperation with the portal. Mapping the rear portal frame to obtain a portal frame of a road on the other side matched with the rear portal frame as a mapping rear portal frame, taking the obtained shortest path as a real path through which the vehicle passes in portal frame data, and synthesizing all portal frame data to obtain a restored path. According to the invention,the obtained portal data is expanded, then the expanded advancing mode is metered, and a real path is obtained through comparison.

Description

technical field [0001] The present application relates to a path restoration method and system in the form of gantry detection. Background technique [0002] With the toll reform of the expressway, it has been revised to the billing method based on the mast. However, since the expressway is bidirectional, it is easy to receive under the existing ETC or CPC billing and information acquisition methods. The signal on the road on the other side, and this kind of signal on the opposite road makes the path wrong, or even the wrong direction, which makes the billing path a big problem, so how to use the premise that there is a large possibility of potential errors In addition, after passing through the gantry, some gantry may not get the signal, which also causes problems in path restoration and billing, and there is no good solution now. Contents of the invention [0003] In order to solve the above problems, on the one hand, the present application proposes a path restoration ...
