1. An information processing apparatus comprising:
circuitry configured to
generate an occupancyMap indicating, for each local area of a frame image, presence or absence of a projection image of a point cloud on a two-dimensional plane in accordance with a positional relationship of points in a three-dimensional space, the point cloud representing an object having a three-dimensional shape as a set of the points;
determine whether a plurality of the points includes a disappeared point in accordance with a positional relationship with a neighboring point in a three-dimensional space, the disappeared point being a point that disappears when the projection image is extracted from the frame image by using the occupancyMap; and
set a value of the local area of the occupancyMap on the basis of a determination that the plurality of the points includes the disappeared point.
