Claim 2:
3. The method according to claim 2, wherein the step of determining, in the first groups and the second groups, edge element sets satisfying the first preset condition comprises:
fitting a plurality of discrete points of the edge elements in each first group to obtain at least one fitting line of the first group, one fitting line in each first group corresponding to at least two edge elements in the first group;
determining, according to a distance between center points of the edge elements in each first group and the corresponding fitting line, an edge element set in the first group satisfying the first preset condition; and/or
clustering center points of the edge elements in each second group to obtain clustering results of the second group;
fitting center points in the clustering results of each second group to obtain at least one fitting line of the second group, one fitting line in each second group corresponding to at least two edge elements in the second group; and
determining, according to a distance between center points of the edge elements in each second group and the corresponding fitting line, an edge element set in the second group satisfying the first preset condition.
