Abstract
With the rapid development of autonomous driving technology, high-precision maps, as one of the core supports, play a significant role in vehicle perception and decision-making capabilities. This study aims to explore the construction and updating technologies of high-precision maps for autonomous vehicles to meet the demands of real-time performance and accuracy in dynamic and complex environments. By integrating multi-source sensor data fusion technology, a deep-learning-based algorithm for generating high-precision maps is proposed, which can effectively extract road features and achieve centimeter-level accuracy in map construction. To address the issue of low efficiency in traditional map updates, a distributed edge computing fr amework is introduced, and an incremental map updating mechanism is designed, significantly enhancing the timeliness of map data. Experimental results demonstrate that the proposed algorithm exhibits excellent robustness and accuracy across various scenarios, with map construction errors below 5 centimeters and update delays reduced to the minute level. Furthermore, this research develops a validation platform for evaluating map quality and its impact on the performance of autonomous driving systems. The findings not only provide technical support for the practical application of high-precision maps but also reduce system resource consumption through innovative updating strategies, laying the foundation for future large-scale deployment.
