Application of Virtual Reality Technology Based on Fast Filtering Algorithm in Switching Operation of Substation

At present, VR(Virtual Reality) technology is widely used in various fields, and its effective integration with power system can realize the application of the combination of 3D model roaming and real simulator patrol with the help of VR technology on the basis of 3D refined modeling of substation. In this paper, the application of VR technology based on fast filtering algorithm in substation switching operation is studied. The sequence control program of switching operation of virtual simulation system is established. Generally, the noise in an image is randomly distributed, and its structural features are not obvious, so it can’t be best represented by atoms in a dictionary. In this paper, a denoising algorithm of image frequency division is proposed in combination with fast filtering algorithm. By repeatedly using the fast filtering algorithm, the original fuzzy infrared monitoring image of substation switching operation is divided into spatial domain low-frequency image and spatial domain high-frequency image, which are denoised by different methods respectively, and the denoised images are fused. The results show that the PSNR value of the image frequency division denoising algorithm based on fast filtering proposed in this paper is obviously higher than that of other algorithms. RMSE value is obviously smaller than other algorithms. It can be seen that this algorithm is helpful to effectively denoise the infrared monitoring image of substation switching operation.
