Abstract: A three-dimensional model generating device includes: a converted image generating unit that, for each of input images included in one or more items of video data and having mutually different viewpoints, generates a converted image from the input image that includes fewer pixels than the input image; a camera parameter estimating unit that detects features in the converted images and estimates, for each of the input images, a camera parameter at a capture time of the input image, based on a pair of similar features between two of the converted images; and a three-dimensional model generating unit that generates a three-dimensional model using the input images and the camera parameters.

Abstract: A three-dimensional model generation method executed by an information processing device includes: obtaining a first three-dimensional model from a measuring device that emits an electromagnetic wave and obtains a reflected wave which is the electromagnetic wave reflected by a measurement target to thereby generate a first three-dimensional model including first position information indicating first three-dimensional positions in the measurement target; obtaining a multi-viewpoint image generated by one or more cameras shooting the measurement target from different positions; and generating a second three-dimensional model by enhancing the definition of the first three-dimensional model using the multi-viewpoint image.

Abstract: This position estimation device of a moving body with n cameras for imaging the surrounding scene is provided with: an estimation unit which, for each of the n cameras, calculates a camera candidate position in a map space on the basis of the camera image position of a feature point in the scene extracted from the camera image and the map space position of said feature point pre-stored in the map data; and a verification unit which, with reference to said candidate positions, projects onto the camera image of each of the n cameras a feature point cloud in the scene stored in the map data, and calculates the accuracy of the candidate positions of the n cameras on the basis of the matching degree between the feature point cloud projected onto the camera image and a feature point cloud extracted from the camera images.
