1. A method executed by a three-dimensional data creation device including a memory storing a program and a processor, the three-dimensional data creation device equipped in a moving vehicle, robot, or drone including a sensor and a communication circuit configured to transmit and receive three-dimensional data to and from an external device, the external device being provided in a traffic monitoring server or another moving vehicle, robot, or drone different from the moving vehicle, robot, or drone, the processor executing the program to perform operations of the method comprising:
generating second three-dimensional data based on three-dimensional data detected by the sensor and first three-dimensional data received by the communication circuit;
extracting third three-dimensional data that is part of the second three-dimensional data from the second three-dimensional data;
transmitting, to the external device, the third three-dimensional data;
determining whether a change has occurred in the second three-dimensional data corresponding to the third three-dimensional data already transmitted; and
when it is determined that the change has occurred, transmitting, to the external device, fourth three-dimensional data that is at least part of the second three-dimensional data in which the change has occurred, the fourth three-dimensional data indicating to the external device that the change has occurred, the change being a change in data of a space having a predetermined size and located a predetermined distance ahead of a current position of the moving vehicle, robot, or drone in a traveling direction of the moving vehicle, robot, or drone.
