摘要： 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.

摘要： A filling rate measurement method includes: obtaining a space three-dimensional model generated by measuring a storage through an opening of the storage using a range sensor facing the storage; obtaining a storage three-dimensional model that is a three-dimensional model of the storage; extracting a target part that is a part of a measurement target in the space three-dimensional model; identifying a line segment indicating a shape of the opening on a two-dimensional image of the opening which is generated; estimating a target three-dimensional model that is a three-dimensional model of the measurement target based on the target part and a three-dimensional coordinate system with respect to the position of the opening on a three-dimensional space identified based on the position of the range sensor, the specific direction, and the shape of the opening; and calculating a filling rate of the measurement target with respect to the storage space.

摘要： A terminal and method for receiving a video delivery of a video signal are provided. The method includes receiving, from a server, the video signal for successively replaying a set of videos selected from among a plurality of videos. The selected videos are respectively selected for each of a plurality of periods in accordance with rating values of the plurality of videos. The rating values are given by a plurality of users. The plurality of videos is obtained by taking an identical scene from a plurality of different viewpoints over a plurality of successive periods. The method further includes successively replaying the selected videos in accordance with the video signal, displaying any video among the plurality of videos, and further displaying when any subject is selected by a user from among a plurality of subjects included in the displayed video, a menu for rating the selected subject.

摘要： A method controls access permission to an image including receiving session information from a first camera at a first position, the session information indicating a subject to be photographed and a session in which the first camera joins, receiving an image of the subject from the first camera, updating the session information such that a second camera, at a second position, joins the session, and monitoring whether the second camera joins the session. A first period is calculated in which the second camera joins the session, a second period is calculated based on the first period, and access permission to a shared image is controlled such that the second camera downloads the shared image during the second period and does not download the shared image outside of the second period, the shared image being one of the image and an image generated based on the image.
