Abstract

The invention provides a visual positioning method. The visual positioning method includes the following steps that S1, images of markers in an environment to be positioned are acquired in advance, and an marker database containing the images of the markers is established; S2, images to be identified of the markers in the environment to be positioned are collected by intelligent equipment, then the images to be identified are matched with the images in the marker database, and then a current position is calculated according to known geometric features of the matched images; and S3, the currentposition is marked at the corresponding position of an electronic map or the current position is output to preset application. The invention provides a visual positioning navigation method. Through the visual positioning method, positioning is carried out for navigation.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a visual positioning method and a navigation method thereof. Background technique [0002] The location-based service (Location Based Service, LBS) industry is increasingly emerging. This service obtains the location of the mobile terminal through the wireless communication network of the telecom mobile operator or an external positioning method (such as GPS) to provide users with short-range service needs. In the outdoor environment, GPS positioning can solve most of the positioning needs. [0003] In some cases, when the satellite signal reaches the ground, it is weak and cannot penetrate buildings, so it is necessary to use indoor positioning technology as a means of positioning to solve the location of the positioning object indoors. Since the positioning accuracy of civilian GPS is about ten meters, this accuracy is not enough in some outdoor situations. For example, wh...
