Method and apparatus for generating road annotation, device and storage medium

An electronic device, comprising:

• at least one processor;
• and
• a storage device, in communication with the at least one processor,
• wherein the storage device stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor, to enable the at least one processor to perform operations comprising:
• generating a road quantity and a road width in a tag picture;
• generating, for each road in the tag picture, a start point and an end point of the road;
• generating at least one point between the start point and the end point;
• drawing, for two adjacent points, a line segment from a previous point to a next point, wherein a width of the line segment is equal to the road width;
• and
• generating slanted box annotation information based on a coordinate of the previous point and a coordinate of the next point, wherein the slanted box annotation information comprises an intersection point of diagonal lines, a width, a height and a slant angle of a slanted box.

A non-transitory computer readable storage medium, storing a computer instruction, wherein the computer instruction is used to cause a computer to perform operations comprising:

• generating a road quantity and a road width in a tag picture;
• generating, for each road in the tag picture, a start point and an end point of the road;
• generating at least one point between the start point and the end point;
• drawing, for two adjacent points, a line segment from a previous point to a next point, wherein a width of the line segment is equal to the road width;
• and
• generating slanted box annotation information based on a coordinate of the previous point and a coordinate of the next point, wherein the slanted box annotation information comprises an intersection point of diagonal lines, a width, a height and a slant angle of a slanted box.
