Methods and apparatus for automated detection of the presence and type of caps on vials and containers

摘要

Methods, systems and apparatus for determining the presence of a cap on a container are provided. An exemplary method comprises capturing an image of an object; extracting an area of interest from the image; determining from the image a position of one or more edges of the object; and determining the presence of a cap based on a comparison of the one or more edge positions to reference data. Numerous other aspects are provided.

1. A method for determining the presence of a cap on a container comprising:
capturing an image of an object; extracting an area of interest from the image; determining from the image a predominant primary color and a secondary color; and determining from the image a position of one or more edges of the object; wherein the determining a predominant primary color and a secondary color comprises translating the primary color and the secondary color into respective color vectors, creating a multidimensional vector based on the determined edge positions, adding the color vectors to the multidimensional vector, and determining the presence of a cap based on a comparison of the multidimensional vector reference data stored in a reference database including at least one of a vertical coordinate, a horizontal coordinate, a width, or a cap color.
