The embodiment of the invention discloses a road surface condition determination method and device, equipment and a medium, and relates to a navigation technology in the technical field of computers. The method comprises the following steps: determining a first pavement condition of a target road according to vehicle trajectory data associated with the target road in a target area; screening target roads in the target area according to the first road surface condition to obtain residual target roads; and identifying the road images associated with the remaining target roads to obtain second road surface conditions of the remaining target roads. According to the embodiment of the invention, the road of which the road surface condition may change is screened out based on the vehicle trajectory data, and the road surface condition is accurately identified according to the road image associated with the screened road, so that a road surface condition identification scheme with both efficiency and accuracy is provided, and a favorable condition is provided for determining the road condition.

    本申请实施例公开了一种道路路面状况确定方法、装置、设备和介质,涉及计算机技术领域中的导航技术。其中方法包括:根据目标区域中目标道路关联的车辆轨迹数据,确定目标道路的第一路面状况;根据第一路面状况对目标区域中目标道路进行筛选,以得到剩余的目标道路;对剩余的目标道路所关联的道路图像进行识别,以得到剩余的目标道路的第二路面状况。本申请实施例实现基于车辆轨迹数据筛选出路面状况可能发生变化的道路,并根据筛选出的道路所关联的道路图像,对道路路面状况进行精准识别,从而提供了一种兼具效率和准确度的道路路面状况识别方案,为确定道路状况提供了有利条件。
