Abstract:
In order to meet the navigation and real-time reflection of road information and events for autonomous vehicles, an intelligent fine-grained high-precision map model was introduced, to solve the construction of high-precision maps in the field of intelligent transportation and provide accurate and real-time navigation guidance for autonomous vehicles. The relationship between the construction of lane-level road networks and the methods for generating intelligent fine-grained high-precision maps was studied, and a high-precision map generation method based on the FCPA was proposed, which includes steps such as lane geometry calculation, intersection graph construction, and other lane trajectory calculations. The effectiveness of the proposed method was validated through experiments. The results show that the FCPA outperforms traditional map generation algorithms in terms of accuracy and efficiency, it accurately captured the details and features of the lane-level road network, reduced unnecessary calculations and redundant information during map generation, and improves efficiency by reducing time consumption, and the FCPA is capable of handling large-scale map data while maintaining the required map accuracy, striking a balance between accuracy and efficiency. Additionally, the proposed FCPA has the capability of dynamically updating maps, and can update map information in real-time according to changes in the traffic environment, ensuring the accuracy and practicality of the map. This method provides accurate road information and navigation guidance for intelligent transportation systems, enhancing system safety and convenience.2 tabs, 10 figs, 24 refs.
