Claim 1:
2. The method according to claim 1, wherein the step of determining, according to positions of the edge elements in the visualization interface, at least one edge element set satisfying a first preset condition comprises:
determining, according to angles between the edge elements and a preset direction and a first mapping relationship, first groups matching the edge elements, the first mapping relationship comprising a correspondence between different angle ranges and the first groups, and the angles between the edge elements and the preset direction in the first group comprising at least one different angle;
determining, according to the angles between the edge elements and the preset direction and a second mapping relationship, second groups matching the edge elements, the mapping relationship comprising a correspondence between different angles and the second groups, and the angles between the edge elements and the preset direction in the second group being identical; and
determining, in the first groups and the second groups, edge element sets satisfying the first preset condition.
