The embodiment of the invention provides a vehicle track and road matching method, equipment, a device and a storage medium. Acquiring vehicle navigation data and map data; wherein the map data comprises road position data corresponding to the vehicle navigation data; inputting the vehicle navigation data and the map data into a trained hidden Markov model to obtain at least one alternative road contained in the map data; and inputting the alternative vehicle navigation data and the alternative map data of the at least one alternative road into a trained deep learning model, and determining a target road from the at least one alternative road. At least one alternative road is preliminarily determined by adding more dimensions of vehicle navigation data and map data, and based on the multidimensional vehicle navigation data and map data. The target road is screened from the alternative roads, and the accuracy and the processing efficiency of determining the matching result of the vehicle and the road are improved by increasing the data dimension and a plurality of model processing modes.
本申请实施例提供一种车辆轨迹与道路匹配方法、设备、装置及存储介质。获取车辆导航数据和地图数据;其中,所述地图数据包括对应于所述车辆导航数据的道路位置数据;将所述车辆导航数据和所述地图数据输入训练好的隐马尔科夫模型,得到所述地图数据中包含的至少一个备选道路;将所述至少一个备选道路的备选车辆导航数据和备选地图数据输入训练好的深度学习模型,从所述至少一个备选道路中确定目标道路。通过增加更多维度的车辆导航数据和地图数据,并基于多维的车辆导航数据和地图数据初步确定至少一个备选道路。进而从备选道路中筛选得到目标道路,通过增加数据维度以及多个模型处理方式,提升确定车辆与道路匹配结果的准确率以及处理效率。
