The invention relates to the technical field of intelligent traffic, in particular to a driving track restoration method, equipment and device, which are used for improving the accuracy of track restoration, and the method comprises the following steps: determining a path starting point and an end point of a to-be-restored target path from adjacent road nodes of a trip chain of a target vehicle; forming a directed graph based on a plurality of paths from a path starting point to an end point; iteratively determining candidate paths from the plurality of paths until the number of the candidate paths reaches a first threshold value or the length of the candidate path determined most recently is greater than a second threshold value; in each iteration process, determining a shortest path from the directed graph after the last iteration, increasing the length of each road section of the shortest path in the directed graph, and taking the shortest path as a candidate path when the similarity between the shortest path and other candidate paths is lower than a similarity threshold value; and determining an index value obtained by evaluating each candidate path based on the evaluation index, and determining a target path from each candidate path based on the index value.
本申请涉及智能交通技术领域,特别涉及一种行车轨迹还原方法、设备及装置,用以提高轨迹还原的准确性,在该方法中,从目标车辆的出行链的相邻道路节点中确定待还原的目标路径的路径起点及终点;基于由路径起点到终点的多条路径构成有向图;从多条路径中迭代确定候选路径,直至候选路径的数量达到第一阈值或最近一次确定的候选路径的长度高于第二阈值;在每次迭代过程中,从上一次迭代后的有向图中确定最短路径,增加有向图中最短路径的各路段的长度,并在最短路径与其他候选路径的相似度低于相似度阈值时,将最短路径作为候选路径;确定基于评价指标对各候选路径进行评价获得的指标值,并基于指标值从各候选路径中确定目标路径。
