Problems solved by technology

This method still has the problem that it is difficult for users to accurately mark their own position and direction on the map. Therefore, the effect of AR navigation deviation correction using existing methods is very limited, it is difficult to effectively improve the accuracy of navigation correction, and it is impossible to achieve accurate AR positioning and navigation.

Embodiment Construction

[0036] Below in conjunction with accompanying drawing, further describe the present invention through embodiment, but do not limit the scope of the present invention in any way.

[0037] The present invention provides a positioning and deviation correction method for a navigation system. The user inputs deviation correction parameters, calculates and updates the coordinates of a target position through vertical position deviation correction, plane position deviation correction, and plane angle deviation correction, so as to realize positioning deviation correction of the navigation system and improve AR navigation effect.

[0038] figure 2 Shown is the method flow of interactive AR deviation correction using the method of the present invention, and the specific operations include:

[0039] A. The user operates the correction control on the correction terminal (such as pressing the control button once);

[0040] B. Correction control input correction parameters to the system;...

Abstract

The invention discloses a positioning deviation rectification method for a navigation system. The method comprises the following steps: designing a deviation rectification control for inputting and adjusting deviation rectification parameters, and respectively carrying out vertical position deviation rectification, plane position deviation rectification and plane angle deviation rectification according to the deviation rectification parameters; and correcting a navigation element under a three-dimensional rectangular coordinate system of the augmented reality navigation system from an initial position to a new position to make the corrected new position better conform to the actual position of the navigation element. The user can simply and conveniently rectify the AR navigation, and the AR navigation effect is improved.

Description

technical field [0001] The invention relates to a navigation positioning technology, in particular to a navigation system positioning deviation correction method, which enables the user to simply and quickly correct the navigation positioning error through interaction with the user. Background technique [0002] There are errors in various positioning and navigation. Navigation systems can reduce the impact of errors through various correction methods. In the prior art, the navigation system mainly adopts system automatic deviation correction (for example, by means of route network matching, etc.), but the automatic deviation correction still cannot guarantee 100% correct positioning and navigation. [0003] When actually using the positioning and navigation system, users sometimes find that their own position on the map is incorrect and need to be manually adjusted and corrected. Some navigation systems also provide users with deviation correction functions according to t...
