Camera based monitoring system for deep hole measurement

Camera based monitoring system has vital role in measuring deep hole parameters especially hole consists of long length and small diameter. The monitoring will help to eliminate errors in measuring deep hole parameters such as roundness, cylindricity etc. This paper proposed a camera based monitoring system for deep hole measurement. The camera is attached to the measurement head and rotates with the rotation of the measurement unit. It captures images, records videos and saves the measurement data in the storage. The monitoring system is aimed to enhance system´s safety and reliability in measuring deep holes as well as to improve measurement accuracy.
