Problems solved by technology
However, because the existing navigation system is inaccurate in positioning the spatial position, the patient cannot be accurately located, and it is easy for the patient to find the corresponding department according to the navigation system.
At the same time, many devices in the hospital have signal shielding requirements. Therefore, when the existing navigation system encounters signal shielding in the hospital, it will cause positioning difficulties and make it more difficult to achieve accurate navigation.

Embodiment Construction
[0039] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0040] According to the applicant's research, it is difficult for patients to see a doctor quickly because they do not understand the functional division of the hospital when they seek medical treatment in the hospital, which wastes time for seeing a doctor. Therefore, patients have navigational needs in the hospital. However, existing navigation systems generally need to rely on positioning systems such as GPS and Bluetooth to achieve positioning and navigation. The GPS positioning system usually can only realize horizontal position positioning, that is, it only has longitude and latitude positioning coo...

The invention discloses a live-action auxiliary navigation method and a navigation system, and belongs to the technical field of navigation. The method comprises steps of framing scenes inside and outside a building, setting a reference mark to form a pre-stored image, and storing the pre-stored image in a database; inputting a destination; framing through a mobile phone camera, calling a pre-stored image in the system for comparison, and positioning according to a marker recognized in the framing image to determine the initial position of the user; and finally, planning a user advancing pathand carrying out live-action auxiliary navigation. In the process, a GPS and other positioning systems are not needed, and even if the signal is shielded and interrupted, the position of the user canbe determined according to comparison of the framing image and the pre-stored image and navigation is carried out. Compared with the prior art, the live-action auxiliary navigation system provided bythe invention can meet the navigation requirement of the user without depending on a GPS (Global Positioning System) and other positioning systems, and the user can be accurately navigated even in a signal shielding area, so that the user can quickly arrive at a specified destination.
Description
technical field [0001] The invention belongs to the technical field of navigation, in particular to a real-scene auxiliary navigation method and a navigation system. Background technique [0002] Navigation is the process of guiding people or objects to move from one place to another, mainly by locating the initial position and the coordinates of key positions, and reasonably planning the driving route to achieve the purpose of quickly reaching the designated position. [0003] Existing navigation devices usually need to rely on positioning systems like GPS to achieve positioning, and such systems usually can only achieve horizontal position positioning, that is, only have longitude and latitude coordinates, but not vertical coordinates. Therefore, when navigating in a spatial position, inaccurate positioning is likely to occur, which leads to inaccurate navigation. [0004] This situation is more obvious in the hospital. When the patient does not know the location of the ...
