Research on Innovation Strategy and Practice of Environmental Art Design for Digital Transformation

With the deep development of digital transformation, the field of environmental art design is experiencing unprecedented changes.In this study, under the 3D scene reconstruction algorithm, the feature points of environmental art design images are collected and extracted using the camera selfcalibration algorithm, and the shape and topology of the point cloud dataset interpolated surfaces are explored using the triangular meshing algorithm.The rotation matrix is obtained by optimising the internal and external parameters of the camera using the essential matrix, basis matrix and Kruppa's equation to clarify its effect on the efficiency of digital feature extraction of images in the process of environmental art design.The results show that the mesh surfaces constructed by the algorithm proposed in this paper make better use of the point cloud data when the number of cloud points input for environmental art design is the same.The rotation matrix algorithm used in this paper can increase the correct matching point pairs of the data, reduce the false matching point pairs, reduce the false matching rate, reduce the matching time, and eliminate more false matching points.And the triangular grid formed by this method is more uniform, and the quality of the grid is improved.In addition, the average satisfaction ratings of the subjects on the nine secondary test indicators are 4. 45, 4.95, 4.75, 4.18, 4.70, 4.60, 4.44, 4.50 and 4.40, respectively.It can be seen that the effect of the application of the digital transformation of the 3D model proposed in this paper has been affirmed.
