Abstract: A display method is a display method performed by a display device that operates in conjunction with a mobile object, and includes: determining which one of first surrounding information, which is video showing a surrounding condition of the mobile object and is generated using two-dimensional information, and second surrounding information, which is video showing the surrounding condition of the mobile object and is generated using three-dimensional data, is to be displayed, based on a driving condition of the mobile object; and displaying the one of the first surrounding information and the second surrounding information that is determined to be displayed.

Abstract: A three-dimensional reconstruction method of generating a three-dimensional model including a three-dimensional point cloud using images obtained by image capturing devices that capture a common three-dimensional space includes acquiring the images captured at corresponding timings and generating three-dimensional points based on the acquired images. The generating includes generating one or more first three-dimensional points based on a result of a first matching performed on points in two or more first images obtained by two or more first image capturing devices, of the image capturing devices, having fields of view with higher similarity than a predetermined threshold, and generating one or more second three-dimensional points based on a result of a second matching performed on points in two or more second images obtained by two or more second image capturing devices, included in the image capturing devices, having fields of view with lower similarity than the predetermined threshold.

Abstract: A three-dimensional reconstruction method includes: reconstructing a first three-dimensional model from a first multi-viewpoint image obtained by shooting a real space, and reconstructing a second three-dimensional model from a second multi-viewpoint image obtained by shooting the real space at a different time; and matching world coordinate systems of the first three-dimensional model and the second three-dimensional model.

Abstract: A camerawork generating method includes: generating, from a multi-view video of a same scene captured from different viewpoints, a three-dimensional model for the scene; determining a target scene which is included in the scene and is a target for which a free-viewpoint video of the three-dimensional model as viewed from a virtual camera is to be generated; and generating a camerawork representing a temporal change in a position and an orientation of the virtual camera in the free-viewpoint video.
