Abstract

See full text

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.
