Abstract
A three-dimensional model search method includes a step of producing a plurality of two-dimensional images obtained by observing a three-dimensional model as an object of search from points of view different from one another. In a first value extraction step, the respective feature values of the two-dimensional images are extracted from the plurality of two-dimensional images. In a search key input step, a two-dimensional image as a search key is inputted. In a second extraction step, the feature value is extracted from the two-dimensional image as the search key. In a similarity search step, the feature values extracted in the first and second extraction steps are used to carry out similarity search, and a three-dimensional model which is similar to the search key is outputted.
