Information processing apparatus and processing method thereof

摘要

An information processing apparatus acquires a plurality of geometric features and normals at the respective geometric features from a target object arranged at the first position. The information processing apparatus also acquires a plurality of normals corresponding to the respective geometric features of the target object from a shape model for the target object that is arranged at the second position different from the first position. The information processing apparatus calculates direction differences between the acquired normals for respective pairs of corresponding geometric features of the target object and shape model. The information processing apparatus determines whether or not occlusion occurs at each geometric feature by comparing the calculated direction differences with each other.

主权项

1. An information processing apparatus comprising:
a first acquisition unit configured to acquire a plurality of parts and normals at the respective parts, from a target object arranged at a first position, wherein each of the plurality of parts include a geometric feature; a second acquisition unit configured to acquire normals corresponding to the respective parts of the target object from a shape model for the target object that is arranged at a second position different from the first position; and a determination unit configured to determine whether the target object is occluded by another object which is different from the target object based on the normals acquired by said first acquisition unit and the normals acquired by said second acquisition unit.
