摘要

随着互联网时代的高速发展,更多基于位置的新型行业逐步发展起来,例如“互联网+”智能交通、无人系统等,但这些行业的发展都需要高精度的位置数据作为支撑,而传统导航地图5 m的精度无法满足需求,因此高精度道路导航地图概念被提出。高精度道路导航地图具有更加丰富细致的道路信息,可以更加精准地反映道路的真实情况。与传统地图相比,它的图层数量更多,图层内容更加精细,具有新的地图结构划分。正是因为高精度道路导航地图丰富的信息含量,使得它具有庞大的数据量,而传统的集中式大数据处理模式无法满足它的计算需求。因此,本文提出 “众包+边缘计算”的大数据处理模式来解决高精度道路导航地图的计算问题。目前,高精度道路导航地图已进入高速发展状态,但发展过程中仍面临着一些需要解决的问题。
