MEASUREMENT ROUTE DESIGN METHOD, MEASUREMENT ROUTE DESIGN APPARATUS AND NON-TRANSITORY COMPUTER-READABLE REACORDING MEDIUM STORING PROGRAM

1 . A measurement route design method, comprising a computer executing:

collecting first measurement information measured by passive measurement;

estimating an estimation map representing a communication status at each position using the first measurement information; and

designing a measurement route of active measurement using the estimation map.

2 . The measurement route design method according to claim 1 , wherein

in the estimating,

a communication status of each position is estimated by a Gaussian process using the first measurement information, and a result of the estimating is estimated as an estimation map.

3 . The measurement route design method according to claim 1 , wherein

in the designing,

the measurement route is designed using the estimation map and a predetermined acquisition function, such that a position where the acquisition function is maximized is a measurement position where next active measurement is performed.

4 . The measurement route design method according to claim 1 , wherein

in the designing,

using the estimation map and a predetermined acquisition function, top predetermined number of positions having a large value of the acquisition function are determined,

a route that travels the predetermined number of positions that are determined and a measurement position of a current active measurement is calculated, as a traveling salesman problem solution, and

the measurement route is designed such that a position reached by moving within a predetermined cost along the route is a measurement position at which next active measurement is performed.

5 . The measurement route design method according to claim 1 , wherein

in the estimating,

the estimation map is estimated again by further using second measurement information indicating a measurement result of the active measurement according to the measurement route, and

in the designing,

the measurement route is redesigned using the estimation map estimated again.

6 . The measurement route design method according to claim 1 , further comprising setting the measurement route in a vehicle or an unmanned aerial vehicle that performs the active measurement.

7 . A measurement route design apparatus comprising:

a memory; and

a processor coupled to the memory and configured to

collect first measurement information measured by passive measurement,

estimate an estimation map representing a communication status of each position using the first measurement information, and

design a measurement route of active measurement using the estimation map.

8 . A non-transitory computer-readable recording medium storing a program for causing a computer to execute the measurement route design method according to claim 1 .
