Abstract

See full text

An assembly includes a fish tape device or a duct rodding device having digital measurement unit attached thereto. A tape is housed in the fish tape device or a duct rodding device and is paid out of the device. The digital measurement unit includes an optical sensor which is positioned proximate to the tape. As the tape is passed by the optical sensor, the optical sensor uses digital image correlation to take successive images of the tape to determine a length measurement of tape that has passed by the optical sensor.
