The embodiment of the invention provides a three-dimensional traffic data processing method. The method comprises the following steps: in response to an initialization stage of a terminal, acquiring at least one piece of pre-positioning information and/or at least one piece of sensing information of the terminal; on the basis of at least one piece of pre-positioning information and/or at least one piece of sensing information, global positioning is carried out on the terminal according to a multi-level road element set of three-dimensional traffic, and the current position and the current level of the terminal are determined; in response to the movement stage of the terminal, acquiring preceding and following association information from the multi-level road element set according to the position and the level of the terminal at the at least one related moment; wherein the related moment comprises at least one of a current moment and a preset number of historical moments before the current moment, and the preceding and following association information at least comprises first road element information of a current hierarchy and second road element information of a hierarchy connected to the periphery of the current hierarchy; and performing auxiliary positioning on the terminal based on the front and back relay association information.
本说明书实施例提供一种立体交通数据处理方法,包括:响应于终端处于初始化阶段:获取终端的至少一个预定位信息和/或至少一个传感信息;基于至少一个预定位信息和/或至少一个传感信息,根据立体交通的多层级道路元素集对所述终端进行全局定位,确定终端的当前位置和当前层级;响应于终端处于移动阶段:根据终端在至少一个相关时刻的所在位置和所在层级,从多层级道路元素集中获取前后继关联信息;其中,相关时刻包括当前时刻、当前时刻之前的预设数量的历史时刻中的至少一个,前后继关联信息至少包括当前层级的第一道路元素信息,当前层级的周围相连层级的第二道路元素信息;基于前后继关联信息,对终端进行辅助定位。
