Live action navigation method and live action navigation device

Abstract

The invention provides a live action navigation method and a live action navigation device. The live action navigation method comprises the following steps of: obtaining a real image I of the current scene of a user from a user image collection device; obtaining an image, which corresponds to a geographic position at a distance from the current geographic position of the user in a predetermined range, from a network image database so as to form an image data set U; transmitting the real image I and the image data set U to an image matching system, and obtaining an image U0 in the image data set U, which has highest matching degree to the real image I, from the image matching system; determining orientation information of the image U0 from the network image database, and determining a route of the user by utilizing the orientation information, a geographic position B and an action path from the current geographic position B of the user to a destination A. According to the invention, the route to the destination can be conveniently selected by the user, and the data quantity received by a mobile terminal is reduced.

Description

【Technical field】 [0001] The invention relates to the field of computer application technology, in particular to a real-scene navigation method and a real-scene navigation device. 【Background technique】 [0002] With the development of electronic map navigation system, it has brought great convenience to people's travel. It usually uses satellite positioning signals, wireless communication network or WIFI network to locate the user's current geographical location, and uses dynamic programming to plan the user's current location. path of action. [0003] At present, most of them are based on two-dimensional (2D) top view logical maps, but in practical applications, when the user reaches a fork in the road, the navigation map can only give the planned route, but cannot indicate the specific intersection currently selected by the user in real time , because there is a big gap between the 2D top view logic map and the real environment where the user is in, the user still needs ...

Problems solved by technology

However, the street view image is pre-shot. Due to the difference in the angle of the user, the street view is different from the actual scene where the user is. It is necessary for the user to locate the location of the street view corresponding to the scene where the user is located. It is also difficult for the user to choose the direction of action. , and the amount of street view image data received by the mobile terminal is too large
