Abstract

The invention discloses a digital rubbing manufacturing method and system based on a triangular grid model and a storage medium. The method comprises steps of step (1), generating a triangular grid model of an object of a to-be-manufactured digital rubbing and carrying out smoothing processing on a normal vector of each top point of the triangular grid model; step (2), selecting the region of theto-be-manufactured digital rubbing and setting the radius of a virtual robbing pack; step (3), according to the radius of the virtual robbing pack, calculating the height of each top point of regionsof the to-be-manufactured digital rubbing of the triangular grid model, and converting the height value of each top point into a gray scale value; and step (4), according to the gray scale values, carrying out orthographic projection of the regions of the to-be-manufactured digital rubbing into images so as to obtain digital rubbings.

Description

technical field [0001] The invention relates to the technical field of digital archaeology, in particular to a method, system and storage medium for making digital rubbings based on triangular mesh models. Background technique [0002] Rubbing is to print the surface features (characters or patterns) of cultural relics on paper. It is an ancient traditional skill in my country and plays an important role in archaeology. In the process of making rubbings, it is necessary to ink and beat the cultural relics, which will cause certain damage to the cultural relics. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a method, system, and storage medium for digital rubbings based on a triangular mesh model, which uses multi-view stereo technology or a three-dimensional scanner to establish a triangular mesh model of cultural relics, and triangular The normal vector of the mesh model is smoothed, the size of the...
