Abstract
A medication tray may include a boundary wall defining a boundary outline. Markers may be carried by the boundary wall. A mobile device may obtain a first image of the medication tray, and determine a number of the markers from the first image. When the number equals or exceeds a threshold, an edge detection algorithm may be applied to the first image to identify the boundary outline based upon the markers, and generate a stocking list of the tray based upon the outline. When the determined number does not exceed the threshold, the device may obtain a second image of the tray, and determine an updated number of the markers from the first and second images. When the updated number equals or exceeds the threshold, the algorithm may be applied to the images to identify the outline based upon the markers, and generate the stocking list based upon the outline.
