Problems solved by technology

For example, the route description mentioned above consists of 6 navigation segments. When the user browses the route description, since the route description contains too much information, the user needs to compare each navigation segment on the map one by one. In order to understand the driving plan given by the route description, resulting in poor user experience

Abstract

The invention provides a method for acquisition of route description, which comprises the steps of: dividing navigation sections with similar attributes in a navigation path into one navigation section cluster; extracting user-concerned information from each navigation section cluster; and combining all the user-concerned information as the route description of the navigation path. The invention also provides a device for acquisition of the route description and an electronic map server. The server comprises the device for acquisition of the route description provided by the embodiment of the invention. Compared with the existing router description based on navigation actions, the obtained route description is more precise and direct, and users can be deeply impressed by the navigation path and can understand driving schemes more easily.

Description

technical field [0001] The invention relates to the field of Internet map services, in particular to a method and device for obtaining route descriptions, and an electronic map server. Background technique [0002] Navigation guidance technology was first applied in various navigation terminals. Navigation terminals generally adopt the guidance method of refining navigation actions. This method provides prompts at each location that requires users to change driving behavior or generate attention. For example, "drive east along Road A for 1 km, turn right into the ramp". This guidance method can well help the driver of the vehicle to clearly understand the driving operation. [0003] At present, in the field of Internet map services, the technical solution for obtaining route descriptions is: select some attributes of each navigation section in the navigation path, including road name, road length, road direction, navigation action and road sign information, etc., according ...
