Provided is a movement-measurement-processing system capable of quickly identifying a peripheral device for which there is a possibility of abnormally nearing a device of interest. For each pair of interval information sets, a peripheral-device sorting means (74) uses a first projection matrix and maps, on a 2D plane, a region inside a 3D space defined by: a starting point for the interval information of the device of interest; a point having as coordinates the passing-position coordinates at the ending point of the interval information, and the lower-limit arrival time; and a point having as coordinates the passing-position coordinates at the ending point of the interval information, and the upper-limit arrival time. The peripheral-device sorting means (74) sorts the peripheral devices for which there is a possibility of abnormally nearing a device of interest, by performing an intersect determination between the obtained region and a circle, the radius of which is the threshold that is the determination reference for the occurrence or lack thereof of an abnormal nearing, and the center of which is the passing position of the peripheral device. |
