Abstract

A pill identification system includes a device which is configured to collect three-dimensional image data of surfaces of one or more pills, generate geometric features of the pill(s) from the three-dimensional image data, and identify the pill(s) using the geometric features. In some embodiments, the identified pills can be verified for patient administration by comparing the identified pills to prescription information.

Claims

1. A method of performing surface scanning, the method comprising:

projecting a laser light pattern onto a three-dimensional surface, the laser light comprising laser light within at least one of the red and infrared spectrum;

receiving, with a camera, laser light reflected from a portion of the three-dimensional surface; and

using light only from the green and blue spectrums of the reflected light to determine the location of the portion of the three-dimensional surface from which the reflected light reflected.
