Charging method and device and server

The invention provides a charging method, a charging device and a server, relates to the technical field of road traffic, and solves the problem that the construction, operation and maintenance cost of an existing full-automatic charging system is relatively high. The method comprises the following steps: acquiring at least two position points reported by a target vehicle within a preset time period; matching the at least two position points with the road topological graph to determine at least two key points, wherein the key points are nodes formed by breaking each road in the road topological graph according to a preset rule; according to the at least two key points, determining at least one key path, wherein each key path comprises two adjacent key points; and according to the charging information of each key path in the at least one key path, determining a charging result of the target vehicle in a preset time period. 本发明提供了一种计费方法、装置和服务器，涉及道路交通技术领域，解决了现有的全自动收费系统建设及运维的成本较高的问题。该方法包括：获取目标车辆在预设时间段内上报的至少两个位置点；
