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 model distribution method includes: distributing a first model, which is a three-dimensional model of a target space in a target time period, in a first distribution mode; and distributing a second model, which is a three-dimensional model of the target space in the target time period and makes a smaller change per unit time than the first model, in a second distribution mode different from the first distribution mode.

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 three-dimensional data creation method for use in a vehicle including a sensor and a data receiver that transmits and receives three-dimensional data to and from an external device. The three-dimensional data creation method includes: creating second three-dimensional data based on information detected by the sensor and first three-dimensional data received by the data receiver; and transmitting, to the external device, third three-dimensional data that is part of the second three-dimensional data.

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.

Abstract: A three-dimensional data encoding method includes: extracting, from first three-dimensional data, second three-dimensional data having an amount of a feature greater than or equal to a threshold; and encoding the second three-dimensional data to generate first encoded three-dimensional data. For example, the three-dimensional data encoding method may further include encoding the first three-dimensional data to generate the second encoded three-dimensional data.

Abstract: The image decoding method includes: determining a context for use in a current block to be processed, from among a plurality of contexts; and performing arithmetic decoding on a bit sequence corresponding to the current block, using the determined context, wherein in the determining: the context is determined under a condition that control parameters of neighboring blocks of the current block are used, when the signal type is a first type, the neighboring blocks being a left block and an upper block of the current block; and the context is determined under a condition that the control parameter of the upper block is not used, when the signal type is a second type, and the second type is one of “ref_idx_l0” and “ref_idx_l1”.
