Abstract

The invention discloses a method for establishing an optimal perspective parameter system for industrial digital ray image test, which solves the problem associated with prior X-ray digital image test that no correct industrial digital ray image test can be carried out due to lack of the method for establishing an optimal perspective parameter system, and provides a reliable and effective optimal parameter-selecting system for the industrial digital ray image test. The method is: (1) determining the thickness of the work piece to be tested; (2) establishing the curve of U(Kv) swung dash d(mm) on the imaging system; (3) forming the reference curve for U(Kv) swung dash Im(mA) selecting the perspective parameters for modeling the imaging system; (4) fitting the curve from (2) and (3), obtaining the corresponding optimal perspective parameters and the mathematic expression of the modeling parameters; (5) establishing the optimal perspective parameter based on (2) and (3); (6) obtaining the digital image of the work piece meeting class B test.

Description

technical field [0001] The invention relates to a method for establishing an optimal transillumination parameter system, in particular to a method for establishing an optimal transillumination parameter system for industrial digital radiography detection. Background technique [0002] In the field of industrial X-ray inspection, the traditional film inspection system has been used, so the selection method of the optimal transillumination parameters is based on the existence of the film system, and the selection methods of many parameters, such as transillumination voltage and current and transillumination time are all Set for film detection system. With the development of technology, the detection system based on digital detector imaging has been applied in the field of X-ray detection. This kind of digital detector system is completely different from film, so the optimal transillumination parameter selection method based on film is not suitable for the current X-ray digita...
