Route display method, device and system

The invention discloses a route display method, device and system. The method comprises the steps that a motion route from an initial area to a target area and the environmental data of each samplingpoint on the motion route are collected; according to the motion route and the environmental data, a return route for a target object to move from the target area to the initial area is acquired; andthe return route is displayed. According to the invention, the technical problem of low evacuation efficiency, which is caused by the fact that the risk of an evacuation route cannot be quantitativelypredicted in the prior art, is solved. 本发明公开了种路线显示方法和装置、系统。其中，该方法包括：采集从初始区域到目标区域的运动路线和运动路线上各个采样点的环境数据；根据运动路线和环境数据获取目标对象从目标区域移动至初始区域的返回路线；展示返回路线。本发明解决了现有技术中无法对撤离路线的危险性进行量化预测，导致撤离效率低的技术问题。
