As shown in FIG. 3 , the parking position reminder method specifically includes the following steps. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted.

Step S1, the acquisition module 301 uses the panoramic lens 34 to acquire a panoramic image of the vehicle 100 during driving.

In this embodiment, the acquisition module 301 shoots images of the vehicle 100 in different directions through the panoramic lens 34 , and forms the panoramic image through image fusion, and the panoramic image includes the vehicle 100 The road at the current location and the surroundings of the road. It can be understood that the road can be an outdoor road or an indoor road. In this embodiment, the acquisition module 301 may acquire a panoramic image of the vehicle 100 during driving at a preset frequency.

Step S2, the recognition module 302 recognizes the driving path of the vehicle 100 based on the panoramic image. The driving path includes a road traveled by the vehicle 100 from the initial position to the destination position.

In an embodiment, the identifying module 302 identifying the driving path of the vehicle 100 based on the panoramic image includes:

Step 21: The identification module 302 compares the panoramic image with the road picture in the preset high-precision map.

In an embodiment, the identification module 302 selects multiple reference points in the road picture in the preset high-precision map, and it can be understood that the multiple reference points include at least the road and the surrounding environment of the road.

Step 22: When the panoramic image is consistent with the road picture, the identification module 302 determines that the driving path includes the road displayed in the road picture.

In an embodiment, the panorama image and the road picture therein are defined as the coincidence rate of the reference point appearing in the panorama image reaching a preset value or above, for example, 80%.

Step S3, the identification module 302 confirms whether the vehicle 100 is in the parking position.
