    Abstract: A viewer control method for controlling a viewer includes: determining a first region around an actual viewpoint of a frame, the frame having been generated by shooting an object from the actual viewpoint; and outputting information on the first region to the viewer. When the viewer receives a setting operation regarding a viewpoint from a user during displaying of a three-dimensional model of the object, the viewer sets a virtual viewpoint in the first region based on the setting operation, and displays a three-dimensional model of the object viewed from the virtual viewpoint set.

    Abstract: An object amount calculation apparatus includes: a receiver configured to obtain a first three-dimensional model and a second three-dimensional model different from the first three-dimensional model, each of the first three-dimensional model and the second three-dimensional model representing a same space, each of the first three-dimensional model and the second three-dimensional model being constituted with regions having respective attributes; and a processor configured to: align the first three-dimensional model and the second three-dimensional model based on at least one attribute of the first three-dimensional model and the second three-dimensional model; calculate, for each of the attributes, a difference between the first three-dimensional model aligned and the second three-dimensional model aligned; and output (i) a total amount of differences corresponding to two or more attributes among the attributes and (ii) information on the two or more attributes.

    Abstract: A calculation method according to one aspect of the present disclosure obtains three-dimensional points that represent an object in a space on a computer, each indicating a position on the object, classifies the three-dimensional points into groups based on the respective normal directions of the three-dimensional points, and calculates a first accuracy of each of the groups, the first accuracy increasing with an increase of a second accuracy of at least one three-dimensional point belonging to the group. The three-dimensional points are generated by a sensor detecting light from the object from different positions and in different directions. The normal direction of each three-dimensional point is determined based on the different directions used to generate the three-dimensional point.

    Abstract: A three-dimensional model generation method includes: obtaining map information generated by camera calibration executed by controlling one or more cameras to shoot a subject from a plurality of viewpoints, the map information including three-dimensional points each indicating a position on the subject in a three-dimensional space; obtaining a first image from a first view point and a second image from a second viewpoint; determining a search range in the three-dimensional space, based on the map information, the search range including a first three-dimensional point on the subject, the first three-dimensional point corresponding to a first point in the first image; searching for a similar point that is similar to the first point, in a range in the second image which corresponds to the search range; and generating a three-dimensional model using a search result in the searching.
