Solution Overview

Problem

Existing automated driving technologies rely on high-precision map data, which consumes significant storage, computing, and network resources, and fail to effectively integrate real-world environment correlations into navigation displays.

Innovation Solution

Discard high-precision map data and utilize vehicle driving state and environment sensing information to generate an augmented reality map through lane line detection, fusing scene images with driving state prompt elements for multi-dimensional display.

1Measurement precision

If high-precision map data is used for navigation, then navigation accuracy is improved, but storage resource consumption, computing resource consumption, and network resource consumption increase

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential lane line information from the complex high-precision map data by performing lane line detection on real-time scene images. This extraction approach obtains the necessary navigation accuracy while eliminating the need to store and process the entire high-precision map dataset, thereby reducing storage resource consumption.

Inventive Principle:
