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 processing 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 nuclear 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.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.
