Research on image pre-processing techniques for multimode data metrology detection

The test and inspection business in the metrology field and laboratory in the electric power field faces the problems of low degree of automation of experimental data flow, high degree of heterogeneity of sensor transmission signals, low degree of resource management sharing and low degree of intelligence. In the paper, orthogonal projection, perspective projection and other projection transformations are used to rotate the image, and deep learning is used to achieve the correction of distorted document images to complete the image preprocessing of multimode data metrology testing. The experimental results show that the image preprocessing technology proposed in the article can effectively restore the metrology detection image.
