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 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 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: 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.
