Abstract

A navigation method and device are provided. The method includes: receiving start point information and end point information sent by a target device; acquiring a target path navigation video from a start point to an end point based on the start point information and the end point information; and sending the target path navigation video to the target device. Accordingly, the target path navigation video is broadcasted in real time, thereby the user may determine whether a deviation occurs between the target path and the actual route in real time, and an accuracy of navigation is improved.

3. The method according to claim 2, wherein the start point information comprises a start point environment image, and the end point information comprises an end point environment image;

and

the acquiring, by the processor of the server, the target path navigation video based on the start point information and the end point information comprises;

extracting, by the processor of the server, start point reference information from the start point environment image, and extracting end point reference information from the end point environment image;

determining, by the processor of the server, the start point reference information as the start point position information, and determining the end point reference information as the end point position information; and

acquiring, by the processor of the server, the target path navigation video based on the start point reference information and the end point reference information.

4. The method according to claim 2, wherein the start point information comprises a start point environment image, and the end point information comprises an end point environment image;

and

the acquiring, by the processor of the server, the target path navigation video based on the start point information and the end point information comprises;

extracting, by the processor of the server, start point text information from the start point environment image, and extracting end point text information from the end point environment image;

determining, by the processor of the server, the start point text information as the start point position information, and determining the end point text information as the end point position information; and

acquiring, by the processor of the server, the target path navigation video based on the start point text information and the end point text information.

5. The method according to claim 1, wherein the acquiring, by the processor of the server, the target path navigation video from the start point to the end point based on the start point information and the end point information comprises:

intercepting, by the processor of the server, the target path navigation video from one stored candidate path navigation video based on the start point information and the end point information.

6. The method according to claim 1, wherein the acquiring, by the processor of the server, the target path navigation video from the start point to the end point based on the start point information and the end point information comprises:

acquiring, by the processor of the server, the target path navigation video from a plurality of stored candidate path navigation videos based on the start point information and the end point information.

7. The method according to claim 1, wherein before acquiring, by the processor of the server, the target path navigation video from the start point to the end point based on the start point information and the end point information, the method further comprises:

acquiring, by the processor of the server, a candidate path navigation video.

8. The method according to claim 7, wherein the acquiring, by the processor of the server, the candidate path navigation video comprises:

acquiring, by the processor of the server, a mobile video and position information, the position information being position information corresponding to a target image captured by a video capturing apparatus in a stationary status during capturing the mobile video; and

associating, by the processor of the server, the position information with the target image so as to obtain the candidate path navigation video.

9. A system for navigation, comprising:
