Title:
DRUG IDENTIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/172288
Kind Code:
A1
Abstract:
Provided is a drug identification device that, on the basis of the actual travel distance of a packaging bag, determines a boundary candidate near a location as the boundary. The drug identification device comprises: an insertion port for inserting continuous packaging bags having drugs separated into individual packages by a packaging machine; a drive device that transports the packaging bags inserted from the insertion port along a transport path to an imaging area; an imaging element that captures an image of a packaging bag including a drug, in the imaging area; a processor that identifies the drug on the basis of the captured image; and an optical flow sensor disposed upon the transport path. The processor: drives the drive device so that an upstream boundary for the packaging bag is moved downstream by a set distance; calculates the travel distance for the packaging bag from information obtained from the optical flow sensor; and determines, as a downstream boundary, a downstream boundary candidate positioned close to the travel distance, in the image after travel.
