Embodiment 1
[0025] Embodiment one is basically as attached figure 1 As shown, a map matching algorithm based on deep learning (L2MM for short) is mainly composed of four components, namely, trajectory representation learning and enhancement component, pattern recognition and mining component, trajectory matching and generation component, and joint optimization component; L2MM includes Two working steps, offline training step and online inference step; in the offline training step, these four components work together to train a deep model for map matching; in the online inference step, the trained deep model is used , the trajectory representation learning and enhancement component, trajectory matching and generation component participate in the work and return the mapping result of a given trajectory based on test points.
[0026] In this embodiment, the offline training step includes the following steps:
[0027] A1. For a trajectory based on location points in the training data set, fi...
