Method for generating intersection area, electronic device, and storage medium

A computer device, comprising one or more processors and a memory containing program instructions that, when being executed, causes the one or more processors to perform:

• obtaining road information of a target intersection node, the road information being configured for indicating at least two roads related to the target intersection node;
• determining road surface width information of roads based on the road information;
• obtaining a constraint condition and a target function, the target function being configured for indicating a target area size of an intersection area of the target intersection node, the target function comprising an offset variable corresponding to a road of the at least two roads, the offset variable being configured for indicating a distance between the target intersection node and a tangent line of a corresponding road, the constraint condition being configured for indicating a limiting condition of the target area size, and the constraint condition comprising constraint relationships between corresponding offset variables of every two adjacent roads of the at least two roads;
• determining an offset distance of the road based on the road surface width information of the road, the constraint condition, and the target function;
• and
• generating the intersection area of the target intersection node in a map based on the road surface width information of the road and the offset distance of the road.

A non-transitory computer-readable storage medium, comprising instructions that, when being executed, causes a computer device to perform:

• obtaining road information of a target intersection node, the road information being configured for indicating at least two roads related to the target intersection node;
• determining road surface width information of roads based on the road information;
• obtaining a constraint condition and a target function, the target function being configured for indicating a target area size of an intersection area of the target intersection node, the target function comprising an offset variable corresponding to a road of the at least two roads, the offset variable being configured for indicating a distance between the target intersection node and a tangent line of a corresponding road, the constraint condition being configured for indicating a limiting condition of the target area size, and the constraint condition comprising constraint relationships between corresponding offset variables of every two adjacent roads of the at least two roads;
• determining an offset distance of the road based on the road surface width information of the road, the constraint condition, and the target function;
• and
• generating the intersection area of the target intersection node in a map based on the road surface width information of the road and the offset distance of the road.
