Displacement measurement of derrick model base on the non-contact type video measurement technology

摘要

In this paper, a non-contact type video measurement technology is introduced, and the displacements of derrick model are measured by this technology. Then comparative analysis between this measurement results and the finite element analysis results showed that the precision of measurement displacement of derrick model used this technology is good. Therefore, this technology is an effective, convenient, safe, low cost, low labor and a new method of derrick displacement measurement.
