Method of taking an image of an object residing in a transparent, colored container
Abstract:
A method of acquiring an image of a pharmaceutical in a colored, transparent pharmaceutical vial includes the steps of: providing a generally cylindrical, colored, transparent pharmaceutical vial having a closed lower end, the lower end having a radially outward lower section, a radially inward upper section, and a transition section that merges with the upper and lower sections; identifying the transition section of the vial with a vision system; detecting the color of the transition section; illuminating the vial; acquiring an image of the vial and pharmaceutical; and adjusting the colors of the image based on the color of the transition section. In some embodiments, the method further comprises the step of comparing the image to a pre-stored image of an expected pharmaceutical to determine whether the identity of the pharmaceutical in the vial matches the identity of the expected pharmaceutical. This method can improve the reliability and consistency of the images produced.
