Embodiment Construction

[0070] Such as figure 1 As shown, in one embodiment, an indoor positioning and navigation method includes:

[0071] Step S110: Acquire an image taken by the user.

[0072] In this embodiment, a user in an indoor environment can obtain an image of the indoor environment by taking a picture of the surrounding environment through a terminal with a camera. If a user takes a photo via a mobile phone in a large department store, the photo is the image taken by the user.

[0073] In one embodiment, the quality of the image is detected after the image taken by the user is acquired, and the image quality determines whether the feature information in the image can be acquired. The standards for image quality evaluation mainly include: image size, clarity, etc. According to the size and definition of the image, it is judged whether the feature information in the image can be obtained. When the image taken by the user does not meet the feature information extraction, the user is prompted to re...

Abstract

The invention provides an indoor positioning navigation method. The indoor positioning navigation method comprises the following steps: acquiring an image shot by a user; positioning the user who shoots the image according to the image; calculating view angle shooting information of the user according to the image and acquiring the destination of the user and an indoor map corresponding to the destination of the user; and generating an indoor navigation map according to the position of the user, the view angle shooting information of the user, the destination of the user and the indoor map corresponding to the destination of the user, and displaying the view angle shooting information of the user on the indoor navigation map. According to the indoor positioning navigation method, characteristic information in the shot image is acquired without dependence on markers arranged in advance, so that the user can realize positioning and navigation in an unfamiliar or complex indoor environment through the shot image, and the user also clearly knows the own orientation in the indoor environment through the view angle of the shot image under a condition that the user is disoriented.

Description

Technical field [0001] The invention relates to the field of navigation and positioning, in particular to an indoor positioning and navigation method and system. Background technique [0002] Indoor positioning navigation allows consumers in large department stores to use precise positioning functions to determine their location and find where they want to go even in a building. For example, find the nearest toilet, ATM and other related information through navigation. [0003] Traditional indoor positioning and navigation need to take pictures of landmarks arranged in advance and store location information in the database, identify the landmarks for the user to locate, and generate a navigation map based on the user's current location and destination location. [0004] However, traditional indoor positioning and navigation systems need to analyze, identify and match pre-arranged landmarks or wireless signals, and require users to find the recently pre-arranged landmarks to locate t...
