Flying object position calculation system, flying object position calculation method, and flying object position calculation program

摘要

PROBLEM TO BE SOLVED: To enable a spatial position of a flying object with an uncertain moving direction to be easily measured.SOLUTION: A flying object position calculation system comprises a launch azimuth calculation section and a flying object position calculation section. The launch azimuth calculation section calculates a launch azimuth of a flying object on a horizontal plane on the basis of acquisition information about a flying object which flies while maintaining thrust without thrust deflection, which is acquired with an image sensor at three or more of different times. The flying object position calculation section calculates a spatial position of the flying object on the basis of a launch azimuth of the flying object, shooting directions when the image sensor shoots the flying object, the spatial position of the image sensor, and a launching position of the flying object.SELECTED DRAWING: Figure 1
