Problems solved by technology

This is very effective for long-distance navigation, but because GPS signals are often interfered by weather or other environments, the error is from a few meters to tens of meters, so GPS cannot be used for navigation in small areas, such as in buildings
[0003] Many people have encountered this kind of trouble when looking for a specific location in a building: they have seen the house number and location downstairs, but once they walk into the building, they lose their direction and find things hard

Embodiment 1

[0093] In recent years, with the popularization of 4G networks, watching videos online through mobile clients has become very common. In the future, with the increase of network bandwidth and the development of video compression decoding technology, the solution of the present invention can be very conveniently applied to mobile clients.

[0094] image 3 A specific implementation manner in which a user uses the map system of the present invention through a mobile client is shown, but the actual structure is not limited thereto.

[0095] In this embodiment, considering the computing capability and storage capability of the mobile client, both the storage and computing modules are set on the server side. In reality, part of the computing and storage tasks can be transferred to the mobile client according to the actual situation. Of course, it can also be completely transferred to the mobile client, if the computing and storage capabilities of the mobile client allow it.

Embodiment 2

[0100] With the development of intelligent robot technology, intelligent robots that can take pictures of customers and provide inquiry services already exist in high-end shopping malls. Most of these robots are mobile.

[0101] The inventor loads the map system of the present invention on these intelligent robots to realize the purpose of navigating through mobile query devices.

[0102] Figure 4 A schematic structural diagram of the query device 260 is shown. The image acquisition module 261 can be a camera, so that the mobile robot can confirm the current position. The feature library 264 and the map database 265 can be set inside the mobile robot according to the situation, or realize information interaction with the mobile robot through the network.

[0103] Since there is a corresponding relationship between the feature database 264 and the map database 265, after the image recognition, the position of the recognized landmark in the map can be confirmed, thereby real...

Abstract

The invention discloses a map system based on image recognition, wherein the map system comprises: an image acquisition module for collecting real scene information; an image recognition module for recognizing whether the real scene information matches the features in a feature library; the feature library for storing feature information and corresponding position coordinate information; a positioning module for determining the position of a user in the map data of a map database according to the corresponding position coordinate information when the real scene information matches the featuresin the feature library; and the map database for storing map data. The invention further discloses a navigation method based on image recognition.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a map system and a navigation device based on image recognition. Background technique [0002] Most of the navigation systems currently on the market use a Global Positioning System (Global Positioning System, GPS) for navigation. By comparing the detected longitude and latitude of the current location with the longitude and latitude of the electronic map, the current position is displayed, and then the current position and the input terminal position are used to search for the route in the electronic map to plan the best route. In the process of moving, it constantly compares the positioning information with the information of the electronic map route, so as to play the role of navigation. This is very effective for long-distance navigation, but because GPS signals are often interfered by weather or other environments, the error is from a few meters to tens of meters, so GPS cannot be...
