车辆定位数据实时匹配地图解决方案

The solution of mathing vehicle location data and digital map

为实现对大规模车辆定位数据实时、高效、正确的处理,本文针对车辆监控平台,提出了一种解决方案。方案针对运算部分采用简单、高效和具有一定正确率保证的点-线匹配方式作为匹配算法;针对地图数据存储部分采用基于区域划分的数据水平切分技术与GeoHash编码技术相结合的方式。方案实现了对大规模车辆的实时监控,解决了大规模数据下并发处理的问题。同时与传统方案比较,方案在达成相同性能条件下大幅降低了相关硬件成本。

In order to realize real- time,efficient and correct processing of large-scale vehicldata,this paper presents a solution for vehicle monitoring platform.The algorithm is based on the point-line matching method which is simple, efficient and with certain accuracy, the storage of map based on GeoHash codingTechnique and Data Segmentation Technique which is based on RegionPartition.The scheme realizes real- time monitoring of large- scale vehicles and solves the problem of concurrent processing under large-scale data. At the same time compared with the traditional program,the program can achieve the same performance conditions and significantly reduce the cost of hardware-related.
