Abstrakt: By acquiring the CT (Computed Tomography) simulation projection images of artistic relics, the visual expression ability of artistic relics is improved, and a method of acquiring CT simulation projection of artistic relics based on voxel model is proposed. The geometric primitive is established by using the geometric information of artistic objects, and the three-dimensional surface of the objects is reconstructed by the voxel model reconstruction method with intersecting surfaces. The surface rendering of artistic relics is divided into voxel level and slice level. The surface of the object composed of small patches is redrawn by using graphics. The slice level reconstruction method is used to reduce redundant patches in the CT simulation projection process of artistic relics, and the number of points and patches is reduced. By adjusting the transparency of the object, the result can not only show the outer surface of the object, but also the contour edge correspondence and contour stitching algorithm are used to improve the reconstruction accuracy and speed. According to the three-dimensional feature expression of voxel model, the fusion and reorganization of intermediate geometric primitives are realized. The simulation results show that the effect of CT simulation projection reconstruction and three-dimensional visual expression of artistic relics using this method is good, and the accuracy and speed of CT reconstruction of artistic relics are high.
