Problems solved by technology

Radio frequency identification technology combines antennas, tags and readers to identify data, but the design cost is relatively high, and it is easily affected by metal materials, water and other substances, resulting in identification failure or identification error
[0003] Although the above-mentioned indoor positioning technologies have achieved fruitful progress, there are still many problems in positioning accuracy, system stability and cost of use.

Embodiment Construction

[0110] Such as figure 1 and figure 2 As shown, an indoor positioning and navigation method based on image space and panoramic assistance includes the following steps:

[0111] Step 1. Layout of control points and establishment of world coordinate system:

[0112] Step 101, setting at least two control points on each wall in the room, and the distance between two adjacent control points on each wall is 3m-5m;

[0113] Step 102, take any point in the room as the origin O s , to pass through the origin O s and pointing to true north is X s axis, through the origin O s and pointing due east is Y s axis, through the origin O s and perpendicular to the X s Axis and Y s The plane O formed by the axis s x s Y s Point to the sky as Z s Axis, establish the world coordinate system O s x s Y s Z s ;

[0114] Step 103, using a total station to measure the coordinates of a plurality of control points, then obtain the coordinates in the world coordinate system O s x s Y ...

Abstract

The invention discloses an indoor positioning navigation method based on image space and panorama assistance. The method includes the steps: laying control points, and constructing a world coordinatesystem; secondly, correcting a camera, and acquiring indoor sequence images; thirdly, extracting and matching characteristic points; fourthly, eliminating the characteristic points; fifthly, calculating characteristic point space coordinates; sixthly, acquiring indoor panorama images; seventhly, indoor positioning; eighthly, indoor navigating. The method is simple in steps, reasonable in design, good in use effect, low in cost and high in practicability, positioning and navigation are accurate, auxiliary devices are decreased, and positioning accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of indoor positioning and navigation, and in particular relates to an indoor positioning and navigation method based on image space and panorama assistance. Background technique [0002] With the continuous improvement of science and technology and social and economic level, urban indoor scenes are becoming more and more complex, and the demand for positioning and navigation in large shopping malls, general hospitals, transportation hubs and other places is gradually increasing. Large shopping malls hope to use indoor positioning technology It is increasingly important to provide real-time guidance services for consumers who come to shop. At present, the outdoor positioning for users is mainly through the smart phone to receive the signal of the global navigation satellite system or the communication signal sent by the communication base station to complete the positioning of the user by using the distance r...
