The invention discloses a road vehicle searching method and system based on area rasterization, and the method comprises the following steps: drawing a standard driving route on a map, defining a driving time period, and obtaining the driving data of all vehicles whose driving time is within the driving time period; calculating the size of a grid block of each vehicle according to the precipitation, the road visibility and the environment to which the road belongs when the vehicle runs, rasterizing the standard running route according to the size of the grid block, generating a search area of the vehicle, and matching the running data of the vehicle with the corresponding search area to obtain the road matching length of the vehicle; taking the ratio of the road matching length of the vehicle to the length of the standard driving route as the road matching rate of the vehicle; the vehicles with the road matching rates larger than the first matching threshold value serve as full matching vehicles, the vehicles with the road matching rates larger than the second matching threshold value and smaller than the first matching threshold value serve as partial matching vehicles, and vehicle information is output according to matching requirements.
本发明公开了一种基于区域栅格化的道路寻车方法及系统,所述方法包括以下步骤:在地图上绘制标准行驶路线,定义行驶时间段,获取行驶时间在行驶时间段内的所有车辆的行驶数据;根据车辆行驶时的降水量、道路能见度和道路所属环境计算每辆车的栅格块大小,根据栅格块大小对标准行驶路线进行栅格化,生成车辆的搜索区域,将车辆的行驶数据与对应的搜索区域进行匹配,得到车辆的道路匹配长度;将车辆的道路匹配长度与标准行驶路线的长度的比值作为车辆的道路匹配率;将道路匹配率大于第一匹配阈值的车辆作为全匹配车辆,将道路匹配率大于第二匹配阈值且小于第一匹配阈值的车辆作为部分匹配车辆,根据匹配需求输出车辆信息。
