High-precision navigation method, system, medium, and vehicle terminal based on vehicle-mounted camera device

Abstract

The invention provides a high-precision navigation method, system, medium, and vehicle terminal based on a vehicle-mounted camera device. The method comprises the following steps: obtaining a real-time road condition image obtained by the vehicle-mounted camera device; obtaining lane information of a current driving road according to the real-time road condition image; and according to the road information, vehicle positioning information, and electronic map data, performing path navigation based on the lane information. According to the high-precision navigation method, system, medium, and vehicle terminal based on the vehicle-mounted camera device, more accurate navigation is performed according to real-time road condition information obtained by the vehicle-mounted camera device, whichgreatly improves the user experience.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a high-precision navigation method, system, medium, and vehicle-mounted terminal based on a vehicle-mounted camera device. Background technique [0002] Electronic map (Electronic map), that is, digital map, is a map that is stored and consulted digitally using computer technology. The method of storing information on electronic maps generally uses vector image storage, and the scale of the map can be enlarged, reduced or rotated without affecting the display effect. [0003] In the prior art, the vehicle-mounted navigation equipment uses the vehicle-mounted GPS (Global Positioning System) to coordinate with the electronic map for positioning and navigation. It can know the exact location of the vehicle anytime and anywhere while driving the vehicle, and can tell the driver where to go conveniently and accurately. The shortest or fastest path to the destination. ...

AI Technical Summary

Problems solved by technology

[0005] (1) Inaccurate positioning often occurs due to GPS drift, Inertial Measurement Unit (IMU) measurement inaccuracy, etc., resulting in parallel road matching errors;

[0006] (2) Due to lack of map data, map data errors or map data errors, the actual driving track is inconsistent with the planned route, and the vehicle positioning cannot be accurately performed;

[0007] (3) When the road is closed due to maintenance and other reasons, it is impossible to obtain the road status change information in real time, resulting in the route reminder not being timely and causing inconvenience to the driver
