Rationality Modeling of 3D Scanning Image of Digital Print Laser Based on Block Matching Texture Information Repair

The accuracy of digital engraving image modeling of traditional modeling methods cannot be effectively guaranteed. To this end, an image solid modeling method based on laser 3D scanning is proposed. First, the pixel to be repaired is determined according to the priority value of the damaged area, and the neighborhood of the pixel is subjected to block matching processing. Then, using the structural similarity between the block to be repaired and each matching block, a corresponding redundant dictionary is established; the damaged region is repaired by solving the sparse representation problem. Constructing an information conduction model of the digital scanning laser three-dimensional scanning image, collecting the information of the digital scanning laser three-dimensional scanning image, and analyzing its characteristics; then performing priority determination of unknown pixels of the digital printing; then using the 5-level wavelet decomposition method for laser three-dimensional scanning Image feature decomposition and information fusion to achieve rationality modeling of digital print laser 3D scanning images. The simulation results show that the laser scanning modeling method is fast and accurate, and can control the modeling error to a low level. The method of reconstructing the three-dimensional scanned image of digital engraving laser has better repair performance, higher feature fusion degree, higher peak signal-to-noise ratio, improved image quality, and more in print restoration and digital reconstruction applications.
