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.
Claims11
A three-dimensional data generation method comprising:
- wirelessly receiving first data by a device, the device being provided on a first moving vehicle, robot, or drone which moves along a traveling direction, the first data representing three-dimensional positions;
- generating second data based on detection by a sensor provided on the first moving vehicle, robot, or drone, the second data representing at least three-dimensional positions of a space in front of the first moving vehicle, robot, or drone in the traveling direction;
- wirelessly transmitting third data to at least one of a second moving vehicle, robot, or drone following the first moving vehicle, robot, or drone in the traveling direction or a traffic monitoring system, the third data representing three-dimensional positions generated based on the first data and the second data, the space being a static area situated a predetermined distance ahead of the first moving vehicle, robot, or drone on a forward road in the traveling direction and the space being hidden from view of the second moving vehicle, robot, or drone following the first moving vehicle, robot, or drone because of a proximity of the second moving vehicle, robot, or drone from the first moving vehicle, robot, or drone;
- and
- the three-dimensional positions of the space represented by the second data are included in the three-dimensional positions represented by the third data, the detectable spaces being detectable by the sensor, wherein
- a first distance in the traveling direction between the first moving vehicle, robot, or drone and the space varies depending on a moving speed of the first moving vehicle, robot, or drone.
