Embodiment 1

[0023] Such as figure 1 As shown, the present invention provides a two-dimensional code-based indoor positioning and routing panoramic guidance method, the method comprising:

[0024] The present invention includes a navigation interface (that is, an interactive interface) and a transit interface (that is, corresponding to location information, but does not participate in interaction). The user of this method scans the two-dimensional code posted by this service through any application of the two-dimensional code scanner, and then Jump to the transit interface with the location information, and jump to the navigation interface carrying the location information through the transit interface.

[0025] In the navigation interface, use JQuery and CSS technology to design a div container to accommodate the panorama, and it can respond to the drag display function of the panorama. This container is placed in the center of the main interface (that is, the interactive interface). A ...

Embodiment 2

[0030] Core algorithm functions, including:

[0031] 1. Pseudocode of the shortest path algorithm:

[0032]

[0033]

[0034] Concrete technical scheme of the present invention comprises:

[0035] Routing algorithm: The route map of the commercial area can be stored in the form of adjacency matrix, and the d[][] matrix stores the path distance. For example, there is a path with distance w between i and j, then d[i][j]=w. The previous closest node of each path node is stored in the path[][] matrix, for example, k is the closest node to j on the path from i to j, then path[i][j]=k.

[0036] The first half of the present invention is the initialization of d matrix and path matrix, and the second half is the gradual correction of d and path. Between any pair of nodes i and j, if there is a shorter path under the premise of the initialization and the last revised path, then enter the correction: d[i][j]=d[i][k]+d[ k][j]; path[i][j]=path[k][j];. Until the correction is co...

Abstract

The invention discloses a QR code (quick response code) based indoor positioning and routing panorama guiding method. According to the method, a navigation interface, a transfer interface and a user are included. The user scans a QR code of the service through a QR code scanner of any application so as to skip to the transfer interface with position information, and the transfer interface carrying the position information skips to the navigation interface. Through JQuery and CSS technologies, a div container for containing panorama is designed in the navigation interface. The div container response to dragging display of the panorama and is placed right in the center of a main interface (namely an interactive interface). A textbox is arranged right above the div container and is used for entering a destination; a submit key is arranged to be used for submitting; and a uniterming key is arranged to be used for selecting a navigation scheme. After submitting, the user obtains navigation service through the interface.

Description

technical field [0001] The invention relates to an indoor positioning and route selection panorama guidance method based on a two-dimensional code, and belongs to the field of web technologies. technical background [0002] With the more and more common applications of mobile phones in daily life, people's life is increasingly inseparable from mobile phones, and various software emerges as the times require, providing various conveniences for people's travel. In order to be more convenient and quick to use, the QR code has become a kind of identification that can be seen everywhere in life. It can realize information acquisition, website jump, advertisement push, mobile e-commerce, mobile payment and other functions, making the operation easier. fast. [0003] The current positioning-guided function technologies, such as Baidu Maps, Google Maps, and independent GPS navigation technology, are suitable for driving navigation or road walking navigation. However, it is not sui...
