Claim 15:
16. A device for determining a plurality of layers of bounding boxes of an object, comprising: processing circuitry configured to
determine a polyhedron capable of accommodating the object therein as a first-layer bounding box:
select one vertex from a plurality of vertices of the first-layer bounding box as a target vertex;
determine a support plane of the object, the support plane having a normal vector that has a specific direction corresponding to the target vertex and that is closest to the target vertex, the support plane being a plane passing through a point on a surface of the object such that the object is completely located on one side of the support plane; and
cut the first-layer bounding box based on at least the support plane to form a smaller bounding box, as a second-layer bounding box.
