Abstract
Embodiments relate to apparatus and methods for locating a tubular joint using two dimensional images. A tubular feature may be located by capturing a first two dimensional image of a tubular, capturing a second two dimensional image of the tubular including a reference, identifying a tubular joint or stick-up of the tubular from the first or second two dimensional image, and determining a vertical position of the tubular joint or stick-up of the tubular using the reference.
