Abstract

A moving object tracking calculation device evaluates priority of visibility of a tracking target between a high-visibility digital radiography image and a low-visibility digital radiography image of the tracking target, calculates a weight distribution representing relative presence accuracy of the tracking target in the low-visibility digital radiography image using epipolar geometry and a difference in visibility between the high-visibility digital radiography image and the low-visibility digital radiography image, and determines a detection position of the tracking target in the low-visibility digital radiography image using the weight distribution and a similarity distribution of the low-visibility digital radiography image.
