Kind Code:
A1
Abstract:
Provided is a technology for recognizing medical articles such as medical equipment, medical instruments and drugs in an image in a video in real time. The present invention is characterized by: associating and storing a medical article, and m number of first local features comprising feature vectors having from 1 to i dimensions for each of m number of feature points in an image of the medical article; extracting n number of feature points from an image in a captured video; generating n number of second local features comprising feature vectors having from 1 to j dimensions; selecting the smaller number of dimensions from among the number of dimensions (i) or the number of dimensions (j); and recognizing that the medical article is present in the image from the video when a prescribed proportion or more of the m number of first local features up to the selected number of dimensions is determined to correspond to the n number of second local features up to the selected number of dimensions.
