The Q-VID ODL system measures the outer diameter (OD) and length (L) of seamless pipes after the piercing. The system consists of four cameras, two dedicated to the OD and the remaining two to the L measurement.

The outer diameter of a seamless pipe has to be measured at the exit of a gauge while the pipe is still being pierced. The two cameras are mounted at roughly 90 degrees in a space-constrained area in between the piercer and a long array of lifting arms; there is not enough room to install a single, voluminous gauge. For length measurement, the maximum detectable pipe size is up to 11 meters; two lightweight high-resolution cameras are placed on the top of two high poles in sturdy, water-cooled enclosures with fully integrated air purge to minimize maintenance. In case of a longer pipe, the system can be extended.
