1. A method for determining a distance of an object captured by a camera, comprising: (a) receiving, by a controller of a computing device, an image of the object and a label associated with the object, the image captured by the camera coupled to the controller; (b) identifying a label image of the label in the image by the controller; (c) determining a label dimension of the label by the controller, the label dimension comprising a real world size of the label; (d) determining a label image dimension of the label image by the controller, the label image dimension comprising a size of the label image; (e) determining a set of optical characteristics of the camera by the controller; and (f) calculating, by the controller, a label distance using the set of optical characteristics of the camera, the label dimension, and the label image dimension; and (g) announcing the label distance using at least one output component coupled to the controller.
