Online Immersive Platform Image Processing Algorithm for Art Courses based on Virtual Equipment Digital Media Technology

This paper introduces the specific concepts of virtual reality technology and digital media art, explains and analyzes the interaction between the two in the process of creation, and determines the connotation, relationship, advantages and characteristics of the two. The image needs to be pre-distorted in order to get the correct image display on the hemisphere. In this paper, the off-axis reflection projection method is adopted. In order to obtain a more accurate predistorted image, several algorithms are used to realize the mapping deformation from the original image to the predistorted image. Based on the analysis of image processing algorithms suitable for embedded processing platform, an algorithm to reduce low-light video noise by using confidence interval and mathematical expectation is proposed.
