Title:
MOVING BODY TRACKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/211696
Kind Code:
A1
Abstract:
This moving body tracking device is provided with a learning unit (16) for learning the relationship between first movement vectors detected by a movement vector detection unit (14) and a positional change between a tracking region in a reference image and a tracking region in a fluoroscopy image other than the reference image. A region division unit (13) divides a fluoroscopy image for tracking into a plurality of regions. A movement vector detection unit (14) detects second movement vectors between each divided region of the reference image and each divided region of the fluoroscopy image for tracking. A tracking region estimation unit (17) estimates a region including a tracking target from the second movement vectors detected by the movement vector detection unit (14) using the learning results of the learning unit (16).
