Method and device for acquiring road track, and storage medium

A method for generating a road track, the method comprising:

• acquiring, by a second device, coordinate information from a visual odometer, the coordinate information being coordinate information of a location of the visual odometer acquired by the visual odometer in real time when the visual odometer moving on a road in a collecting area, and the collecting area being an area where Global Navigation Satellite System (GNSS) signals are blocked, wherein the coordinate information are spatial relative coordinates of positions between a location corresponding to a set starting point and a location corresponding to a set ending point, the spatial relative coordinates are collected by the visual odometer in real time, the set starting point and the set ending point are different points manually set on a map covering the road in the collecting area, a set starting direction at the set starting point is manually set on the map covering the road in the collecting area, and a spatial relative coordinate of position refers to amount of change including numerical change and direction change relative to the location corresponding to the set starting point wherein the visual odometer moves along the set starting direction at the location corresponding to the set starting point and ends the acquiring the coordinate information at the location corresponding to the set ending point;
• and
• generating, by the second device, a road track on the map covering the road in the collecting area according to the coordinate information, to link the generated road track to an existing road network.

A device for generating a road track, the device comprising:

• at least one processor;
• and
• a memory storing instructions, wherein the instructions when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising:
• acquiring, when the device moving on a road in a collecting area, coordinate information of a location of the device in real time, the collecting area being an area where Global Navigation Satellite System (GNSS) signals are blocked, wherein the acquiring comprises:
• acquiring, in real time, spatial relative coordinates of locations of the visual odometer between a location corresponding to a set starting point and a location corresponding to a set ending point in the collecting area, the set starting point and the set ending point are different points manually set on a map covering the road in the collecting area, a set starting direction at the set starting point is manually set on the map covering the road in the collecting area, and a spatial relative coordinate of a location refers to amount of change including numerical change and direction change relative to the location corresponding to the set starting point, wherein the visual odometer moves along the set starting direction at the location corresponding to the set starting point and ends the acquiring the coordinate information at the location corresponding to the set ending point;
• and
• sending the coordinate information to a second device, causing the second device to generate a road track on the map covering the road in the collecting area according to the coordinate information, to link the generated road track to an existing road network.
