The invention provides a multi-source trajectory analysis method, device and equipment and a readable storage medium. The method comprises the following steps: acquiring a first track data set recorded by a grating system and a second track data set recorded by a video system for the same road section in a preset time period; selecting one piece of track data which is not selected from the first track data set as first track data; the same road section is divided into i sub-road sections, and the road surface types and/or weather conditions between the adjacent sub-road sections are different; according to the road segment segmentation condition, trajectory data from different data sources are segmented, the similarity between the segments is calculated, then the similarity between the trajectory data from different data sources is determined based on the similarity between the segments, the influence of the road surface type and the weather condition on the similarity calculation result is fully considered, and the accuracy of the similarity calculation result is improved. And the multi-source trajectory analysis accuracy is improved.
本发明提供一种多源轨迹分析方法、装置、设备及可读存储介质。该方法包括,获取预设时段内针对同一路段光栅系统记录的第一轨迹数据组以及视频系统记录的第二轨迹数据组;从第一轨迹数据组中选取未被选取过的一条轨迹数据作为第一轨迹数据;将同一路段分为i个子路段,相邻子路段间路面类型和/或天气情况不同;按照路段分段情况,对来自不同数据源的轨迹数据进行分段,并计算每个分段间的相似度,再基于每个分段间的相似度确定来自不同数据源的轨迹数据间的相似度,充分考虑了路面类型以及天气情况对相似度计算结果的影响,提高了多源轨迹分析准确性。
