AI Technical Summary
Technical Problem
Existing muography technologies are inadequate for identifying the structure of moving bodies, as they primarily focus on immovable cavities and do not provide useful information for moving objects.
Method used
A program and calculation device that estimate the velocity and positional relationship of a moving body using charged particle sensors, calculating positions in a stationary coordinate system based on multiple measurement timings and relative positional relationships.
Benefits of technology
Enables the identification of the structure of moving objects by calculating useful information from charged particle measurements, accounting for changing sensor positions relative to the moving object.

Abstract
To provide a program, a calculation device, and a method capable of calculating information useful for identifying a structure of a moving object using measurement values based on charged particles.SOLUTION: The calculation device is configured to: estimate a velocity of a moving body and a second relative positional relation of the moving body with respect to a first charged particle sensor, on the basis of a plurality of first measurement value sets corresponding to each of a plurality of first measurement timings of a first charged particle sensor, a plurality of second measurement value sets corresponding to each of a plurality of second measurement timings of a second charged particle sensor, and a first relative positional relation of the second charged particle sensor with respect to the first charged particle sensor; and calculate a position of the first charged particle sensor corresponding to each first measurement timing in a stationary coordinate system of the moving body, and a position of the second charged particle sensor corresponding to each second measurement timing in the stationary coordinate system of the moving body, on the basis of the estimated velocity, the second relative positional relation, and the first relative positional relation.SELECTED DRAWING: Figure 4
