Automatic inspection and repair of marine propellers

Deformed ship propellers are bent back to their original condition using special machines. Previously, this work was performed manually but today it has been replaced by automatic systems. The current shape of the propeller is measured and stored using an optoNCDT 1700 series laser sensor. The system then automatically recognizes which positions need focusing on. In doing this, the laser sensor measures the lustrous surface of the propeller, which it is able to do extremely well by using fast, real-time surface compensation (RTSC) exposure regulation.
