A computer-implemented method for drawing an intersection, comprising: acquiring road lines of all branches at the intersection based on vector data of the intersection (S101, S201, S301); performing a line-to-surface expansion based on the road lines to obtain road surfaces, and acquiring two side lines of each of the road surfaces (S102, S202, S302); and determining target side line pairs based on side lines of the intersection, and drawing a corner arc at a corner of each of the target side line pairs (S103, S208, S303), wherein each of the target side line pairs comprises two side lines that do not belong to the same road line and are adjacent to each other; characterized in that the method further comprises: recording a binding relationship between the two side lines of each of the road surfaces and the road line, and recording a position relationship between respective side lines and the road line to which the side line belongs, wherein the position relationship comprises being located on left or right of the road line, wherein determining the target side line pairs (S103, S208, S303) comprises: determining road line vectors of all the branches at the intersection according to the vector data, and calculating an included angle of each of the road line vectors with respect to a preset direction of a preset coordinate axis, wherein the preset direction comprises a positive direction and a negative direction; sorting the road lines according to the included angles to obtain a road line order; sorting, according to the position relationship and the road line order, the side lines in a clockwise or counterclockwise manner to obtain a side line order; and determining the target side line pairs according to the side line order and the binding relationship. acquiring road lines of all branches at the intersection based on vector data of the intersection (S101, S201, S301);
