[0117] Refer to the following Figure 3-5 The actual application data is given to further illustrate the method of the present invention.
[0118] The data enhancement method based on noise perturbation and Gaussian blur for local enlarged maps according to the present invention includes:
[0119] Collect a piece of partial discharge raw data, its unprocessed three-dimensional image is as follows image 3 shown.
[0120] Superimpose light, radar, and mobile phone noise interference on the original sample data, and perform three-dimensional processing on the superimposed interference data to obtain the image file after noise superimposition, such as Figure 4 shown.
[0121] Take σ as 1.5, calculate the Gaussian weight matrix for the RGB three colors of the image file after noise superimposition, and superimpose Gaussian blur to obtain the image file as Figure 5 .
[0122] The Gaussian blurred image file and the original file are included in the sample library to complete...
