Abstract

To propose a measurement method for the verticality of deep hole based on monocular vision.The coordinate conversion matrix of pentaprism circumferential scanning is derived, and the circumferential scanning trajectory and characteristics of the targets are simulated and analyzed .Based on the visual axis, the normal direction of the measurement datum is constructed to accurately compensate the error between the camera visual axis and the tube datum.For the simulated tube with a radius of 956.21mm, a thickness of 999.55mm and a verticality of 0 mm, the verticality accuracy measured by the system can reach 0.03mm.The actual test shows that the method of measuring the verticality of deep hole with monocular vision is effective and feasible. The system is easy to operate and highly automated, which can greatly improve the measurement efficiency and ensure the measurement accuracy. It is of great significance to the production and measurement of deep holes in nuclear tube sheet.
