Claim 2:
3. The method according to claim 1, wherein acquiring the plurality of depth edges corresponding to the first three-dimensional model according to the plurality of sub-graphs comprises:
acquiring a degree of each node in each sub-graph of the plurality of sub-graphs, wherein the degree refers to the number of connecting edges between the node and other nodes, and one connecting edge is formed between the node and a node in the same depth layer, and each node in each sub-graph is a depth pixel corresponding to each node in the first three-dimensional model;
obtaining a plurality of depth edge node aggregations based on a node having an octa-connectivity domain direction aggregation degree less than a preset degree value, wherein the depth edge node aggregation refers to a set of depth pixels located at the edge of the same depth layer; and
performing uniqueness detection on a node in each depth edge node aggregation to determine each node belongs to a background pixel or a foreground pixel, and obtaining a plurality of depth edges corresponding to the first three-dimensional model.
