MOVEMENT-MEASUREMENT-PROCESSING SYSTEM, MOVEMENT-MEASUREMENT-PROCESSING METHOD, AND MOVEMENT-MEASUREMENT-PROCESSING PROGRAM

摘要

There is provided a movement-measurement-processing system capable of quickly specifying a peripheral aircraft which can abnormally near to an aircraft of interest. A peripheral aircraft selection means 74 maps a region in a 3D space defined by a start point of period information of the aircraft of interest, a point having the coordinate values of passage position coordinates at an end point of the period information and a lower limit arrival time, and a point having the coordinate values of passage position coordinates at the end point of the period information and an upper limit arrival time onto a 2D plane by use of a first projection matrix. The peripheral aircraft selection means 74 then selects a peripheral aircraft which can abnormally near to the aircraft of interest by determining how the resultant region crosses with a circle whose center is a passage position of the peripheral aircraft and whose radius is a determination standard threshold as to whether abnormal nearing will occur.

1. A movement-measurement-processing system comprising:
a period information creation unit for creating a set of period information each having a 3D coordinate with the coordinate values of 2D coordinates of a passage position of a moving body and its passage time as information on a start point and an end point from a movement plan of an aircraft of interest which is a moving body for which the movement plan is to be adjusted and a movement plan of each peripheral aircraft which is a moving body other than the aircraft of interest; an arrival time calculation unit for calculating a lower limit arrival time which is an end point arrival time when the aircraft of interest moves at an upper limit speed and an upper limit arrival time which is an end point arrival time when it moves at a lower limit speed for each item of period information of the aircraft of interest; a projection matrix calculation unit for calculating a first projection matrix indicating mapping from a 3D space onto a 2D plane based on a period information pair having one item of period information of the aircraft of interest and one item of period information of a peripheral aircraft; and a peripheral aircraft selection unit for selecting a peripheral aircraft which can abnormally near to the aircraft of interest by determining how a region obtained by mapping a region in a 3D space defined by a start point of period information of the aircraft of interest, a point having the coordinate values of passage position coordinates at an end point of the period information and a lower limit arrival time, and a point having the coordinate values of the passage position coordinates at the end point of the period information and an upper limit arrival time into a 2D plane by use of the first projection matrix crosses with a circle whose center is a passage position of the peripheral aircraft and whose radius is a determination standard threshold as to whether abnormal nearing will occur.
