Document Type and Number:
WIPO Patent Application WO/2021/085453
Kind Code:
A1
Abstract:
[Problem] To enable an action including a rod-shaped implement that is being carried by a carrier to be recognized without using a marker for the carrier who is carrying the implement. [Solution] The present invention relates to a visualizer system which performs image processing employing a recognition processing result from a recognition processing device. Furthermore, the recognition processing device according to the present invention is characterized by: recognizing the position in which an implement appears in captured images in which one or a plurality of carriers each carrying a rod-shaped implement are captured by a plurality of image capturing devices; acquiring implement-vicinity region images of an implement-vicinity region including only the implement and the region in the vicinity thereof; recognizing the position in which a prescribed part of the implement appears, from each implement-vicinity region image; acquiring two-dimensional coordinates corresponding to the position of the prescribed part in the captured images; converting the two-dimensional coordinates of the prescribed part, recognized by a two-dimensional coordinate recognizing means on the basis of each captured image, into three-dimensional coordinates in a three-dimensional space in which the carrier is present, and acquiring the three-dimensional coordinates; and recognizing and acquiring the three-dimensional coordinates corresponding to the position of the prescribed part in the three-dimensional space, on the basis of the acquired three-dimensional coordinates of the prescribed part.
