System and method of pill identification

摘要

A system and method for identifying pills by determining a size and shape of each pill in a digital image. The system includes a background grid organized as a grid of alternating-colored shapes. The system also includes a digital camera, a processor and a memory. The processor is used to receive and process the digital image taken by the digital camera so as to determine contours for each pill in the image. The contour determination is refined and is used to determine size and shape information for each pill.

1. A method of identifying a contour of one or more pills, the method comprising:
receiving a digital image representing one or more pills on a background grid, the background grid organized as a grid of alternating-colored shapes; using the grid of alternating-colored shapes to determine an initial estimation of contours for the imaged pills, each contour enclosing a pill part; creating a first refined estimation of contours by separating contours that enclose multiple pills in the initial estimation of contours into individual contours that each only enclose a single pill; creating a second refined estimation of contours by combining pill parts representing a single pill in the initial estimation of contours into a single contour for a pill represented by multiple pill parts; and combining the first and second refined estimation of contours to create an improved estimation of contours.
