摘要
高精度地图是高级别自动驾驶的关键技术支撑,为自动驾驶车辆提供先验知识。传统专业采集的高精度地图更新方式,难以满足自动驾驶对于地图高覆盖度和高鲜度的需求。针对该问题,本文探索了一种基于地图众包的高精度地图更新技术。首先,探讨了高精地图在自动驾驶系统中的重要作用、发展现状和未来趋势;然后,分析了高精地图的构建方式及数据处理流程;最后,研究了高精地图众包更新模式和关键技术。为验证众包更新模式的可行性,进行了应用测试,结果表明众包更新模式具有一定的精度和准确率,为高精地图更新提供了新的实现方式,具有推广价值和意义。
High precision map is the key technical support for high-level autonomous driving,and it can provid prior knowledge for autonomous vehicles.The traditional high precision map updating method collected by professionals is difficult to meet the needs of autonomous driving for high map coverage and freshness.In response to this issue,this article explores a high precision map update technology based on map crowdsourcing.Firstly,the important role,development status and future trend of high precision map in auto drive system were discussed;Secondly,the construction method and data processing flow of high precision map were analyzed;Finally,the high-precision map crowdsourcing update mode and key technologies were studied.To verify the feasibility of the crowdsourcing update model,application tests were conducted,and the results showed that the crowdsourcing update model has a certain degree of accuracy and precision,providing a new implementation method for high-precision map updates,which has promotional value and significance.
