INFORMATION PROCESSING APPARATUS, CONTROL METHOD THEREOF, AND COMPUTER READABLE STORAGE MEDIUM

摘要

An information processing apparatus predicts, based on a geometric model of an object to be measured, an image degradation of the object in an image in which the object is captured by a capturing device. Furthermore, the information processing apparatus searches a two-dimensional image in which the object is captured by the capturing device for a measurement data feature that corresponds to a model feature of the geometric model, and evaluates, using the two-dimensional image, an image degradation with respect to the found measurement data feature. The information processing apparatus calculates, based on the predicted image degradation and the evaluated image degradation, the accuracy of the correspondence between the model feature and the measurement data feature, and collates, based on this accuracy, the geometric model and the object in the two-dimensional image.

1. An information processing apparatus comprising:
a prediction unit configured to predict, based on a geometric model representing a shape of an object to be measured, an image degradation of the object to be measured in an image in which the object to be measured is captured by a capturing device; a searching unit configured to search a two-dimensional image in which the object to be measured is captured by the capturing device for a measurement data feature that corresponds to a model feature of the geometric model; an evaluation unit configured to evaluate, using the two-dimensional image, an image degradation with respect to the measurement data feature found by the searching unit; a calculation unit configured to calculate, based on the image degradation predicted by the prediction unit and the image degradation evaluated by the evaluation unit, an accuracy of the correspondence between the model feature and the measurement data feature; and a collation unit configured to collate, based on the accuracy of the correspondence between the model feature and the measurement data feature, the geometric model and the object to be measured in the two-dimensional image.
