Travel path acquiring method and device, and server

The embodiment of the invention provides a travel path acquiring method, a travel path acquiring device and a server. The method comprises the steps of acquiring multiple pieces of position data of auser, and acquiring a time-based variation trend of geographic positions according to the geographic positions corresponding to time represented by the multiple pieces of position data; determining interference position data from the multiple pieces of position data according to the variation trend and confidence coefficient levels of the geographic positions corresponding to time represented by the multiple pieces of position data; and excluding the interference position data. According to the target position data except the interference position data, an accurate travel path of the user canbe acquired, and thus the acquiring accuracy of the travel path is improved. 本发明实施例提供了种出行轨迹获取方法、装置及服务器，获取用户的多个位置数据，依据所述多个位置数据表示的各时间相应的地理位置，获得地理位置依据时间的变化趋势；根据所述变化趋势以及所述多个位置数据表示的各时间相应的地理位置的置信度级别，从所述多个位置数据中确定干扰位置数据；将干扰位置数据排除，依据除干
