INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND STORAGE MEDIUM

摘要

To measure a three-dimensional shape of a measurement target object at high speeds, an information processing apparatus is configured to acquire an image captured while a pattern including first features and a second feature is projected onto the measurement target object; identify the first features in the captured image, and acquire an initial value of shape information on the measurement target object in an area including the first features; set a candidate for the shape information in a first area based on an initial value of shape information in an area surrounding the first area; decide an area in the pattern corresponding to the first area as a second area, and evaluate a correlation between the second area and the first area based on the second feature in the first area and the second feature in the second area; and derive the shape information in the first area.

1. An information processing apparatus comprising:
an acquisition unit configured to acquire an image captured by an imaging apparatus while a pattern including a plurality of first features and a second feature different from the first features is projected onto a measurement target object; an initial value acquisition unit configured to associate the first features included in the projected pattern and the first features included in a captured image based on the captured image to identify the first features included in the captured image, and acquire an initial value of shape information on the measurement target object in an area including the first features within the captured image based on an identified result; a setting unit configured to set a candidate for the shape information in a first area based on an initial value of shape information in an area surrounding the first area within the captured image; an evaluation unit configured to decide an area in the pattern corresponding to the first area as a second area based on the candidate for the shape information in the first area, and evaluate a correlation between the first area and the second area based on the second feature included in the first area and the second feature included in the second area; and a derivation unit configured to derive the shape information in the first area based on the correlation evaluated by the evaluation unit.
