Abstract

The invention discloses a panoramic map database acquisition system and a vision-based user location positioning and navigating method. A user shoots surrounding symbolic images by a mobile phone, and self-location positioning and live-action map navigation can be completed through image feature identification and rectification, so that a novel navigation mode which is accurate in positioning and fresh in experience is provided. The system and the method have a more obvious effect when used in indoor environment. Besides, the panoramic map navigation manner is adopted, accordingly, the most visual live-action navigation experience is provided for the user, and the user experience can be greatly improved.

Description

technical field [0001] The invention relates to the field of navigation and positioning, in particular to a panorama map database acquisition system and a vision-based positioning and navigation method. Background technique [0002] In recent years, the application of LBS (Location Based Service, location-based service) has gradually become a hot spot, and the navigation technology has developed rapidly. GPS positioning can provide users with a lot of auxiliary information for outdoor positioning and navigation, but it also has obvious defects, that is, in the indoor environment, GPS positioning speed is extremely slow, and the accuracy is low, and even the positioning cannot be completed. Indoor navigation technology has gradually become a research hotspot. In the existing technology, indoor navigation technology mainly uses wireless WIFI, radio frequency identification, geomagnetic field and other technologies for positioning. [0003] With the continuous advancement of s...
