1. A method of determining an initial point for a scan path, the method comprising: acquiring, using a mobile device, an image of an object, the image comprising decodable indicia; decoding, using the mobile device, data from the decodable indicia; determining indicia dimensions of the decodable indicia based on the data comprising scanning the decodable indicia to obtain data indicating the indicia dimensions of the decodable indicia; determining image dimensions of the decodable indicia in the image comprising detecting one or more edges of the object within the image; and calculating an initial location of the mobile device relative to the decodable indicia based on a geometric relationship between the indicia dimensions of the decodable indicia and the image dimensions of the decodable indicia in the image.
