| 英文摘要: |
| A method is proposed to measure the process margin of the main steam inlet and outlet pipe of a nuclear power plant by using an industrial photogrammetry system.This method includes steps of preparation, image acquisition, image processing, and result analysis, as well as the final process-ing margin analysis, and so on.In particular, it suggests a specific method for target-point layout and design of shooting network for the main steam inlet and outlet pipe measurement, and then uses a method of sub-section photography and collation to measure the inner and outer surfaces of the nu-clear power interface pipe.The machining tolerance analysis shows that the method can effectively test whether the machining tolerance data of the interface pipe' s top surface, outer surface and the inner surface reach a critical value, which provides a reliable reference for the next step in this process, and it is a type of machining tolerance detection method worthy of popularisation. |
