Embodiment Construction

[0024] Below in conjunction with accompanying drawing, the present invention is further described:

[0025] The present invention provides a high-precision map-based navigation enhanced display device, which includes:

[0026] Central controller; steering wheel buttons, vehicle front camera, vehicle navigation, high-precision map device, vehicle positioning instrument, vehicle display and vehicle speaker respectively connected with the central controller. The front camera on the vehicle outputs the front road condition information within the first predetermined distance in front of the vehicle to the central controller, and provides the front road condition information within the first predetermined distance in front of the vehicle to the high-precision map device. The vehicle navigation is used for the driver to set the destination, and the vehicle positioning instrument (RTK and GNSS) is used to provide real-time vehicle positioning information to the high-precision map devi...

Description

technical field [0001] The invention belongs to the field of automobile safety driving, and in particular relates to a high-precision map-based navigation augmented reality method and an automobile. Background technique [0002] At present, driver assistance systems mainly rely on millimeter-wave radar and cameras to identify lane lines and vehicle information to achieve acceleration and deceleration and lateral control in a single lane. The car navigation mainly gives the route and prompt information of the standard working condition. Some driving assistance vehicles are equipped with ADAS maps, which can provide information such as road types, curves, ramps, etc., and assist the driving assistance system in speed control, but lane-level positioning cannot be performed due to accuracy reasons. [0003] With the emergence of high-precision maps, the horizontal accuracy reaches centimeter level, which can realize lane-level positioning and more accurate scene reconstruction....
