1. A three-dimensional information processing method, comprising:
determining whether first three-dimensional position information is obtained via a communication channel, the first three-dimensional position information representing a first range in a three-dimensional space;
obtaining second three-dimensional position information generated based on information detected by a sensor;
when the first three-dimensional position information is determined to be obtained via the communication channel, estimating a location of a mobile object having the sensor using the first three-dimensional position information and the second three-dimensional position information; and
when the first three-dimensional position information is determined not to be obtained via the communication channel, (i) obtaining, via the communication channel, third three-dimensional position information which represents a third range narrower than the first range and (ii) estimating the location using the second three-dimensional position information and the third three-dimensional position information.
