| description | The invention relates to the field of spatial big data, in particular to a track positioning method and device and a computer readable storage medium, the method comprises the following steps: acquiring each progress point of a target user in a moving process, and determining a road section endpoint corresponding to each progress point from a preset multi-mode traffic network diagram; using a starting point in each progress point as a path point to iteratively update the priority queue until the path point is an end point in each progress point, and maintaining a road segment end point corresponding to the path point and an end point cost of the road segment end point in the priority queue; and according to the multi-mode traffic network diagram, backtracking each path point from the terminal point to obtain a moving track of the target user. According to the invention, the accuracy of track positioning can be improved.
本发明涉及空间大数据领域，尤其涉及一种轨迹定位方法、设备以及计算机可读存储介质，该方法包括：获取目标用户在移动过程中的各个进度点，并从预设的多模式交通网络图中确定各个进度点各自对应 |
