1. A labelling system comprising:
a container with a curved surface;
a raised tactile label positioned on the curved surface of the container, the raised tactile label including a background and a plurality of projections extending outward from the background, wherein the plurality of projections form a distinct pattern on a lower corner on a first side of the raised tactile label and the distinct pattern on an upper corner on a second side of the raised tactile label;
an image capturing device configured to capture a plurality of digital images of the raised tactile label;
a mapping stored in a hardware memory, the mapping including an entry corresponding to the raised tactile label, the entry including shadow data, color data, density data, and further information;
an image processing device configured to process a first of the plurality of digital images of the raised tactile label to determine the shadow data, the shadow data indicating that a first of the plurality of projections created a shadow on a second of the plurality of projections based on the chrominance of pixels associated with the second plurality of projections, wherein the image processing device determines that the first of the plurality digital images is associated with the entry corresponding to the raised tactile label based on the shadow data;
a user interface configured to communicate the further information associated with the entry.
