An object collation method comprising a registration procedure for registering the registered data of a registered object in a database, and a collation procedure for collating the input image of a target object with the registered data. The registration procedure includes a step of storing the three-dimensional shape of the registered object and a texture space defined by a texture group indicating the luminance and/or color information of each position of the object surface under various illumination conditions. The collation procedure includes the steps of: generating an illumination fluctuation space defined by the image group under the various illumination conditions, at the location and position of the target object in the input image from the three-dimensional shape and the texture space; and collating the target object and the registered object based on the distance between the illumination fluctuation space and the input image.
