Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a system and method for generating an engraving model, and a system and method for 3D printing of an engraving model. Background technique [0002] Traditional sculpture is to pass a piece of plastic (such as plaster, resin, clay, wood, marble, etc.) through the hands of a master artist to create a visible and palpable artistic image with a certain space. Carving and engraving achieve the purpose of artistic creation by reducing the material materials that can be carved, while plastics achieve the purpose of artistic creation by stacking plastic material materials. Traditional carving not only requires extremely high skills of the operator, but also a piece of exquisite workmanship is often It takes several days to complete, and it is difficult to meet people's needs for carving works. 3D printing technology has changed the original traditional mechanical ma...

Problems solved by technology

[0003] The prior art discloses a 3D printing manufacturing method of a seal, using 3D modeling software to establish a 3D model of the seal, and dividing the 3D model into a series of two-dimensional graphics along the Z-axis direction according to equal layer thicknesses, and the 3D printer according to the two-dimensional graphics Printing, because this manufacturing method divides the 3D model along the Z axis according to equal layer thickness, the size of the 3D model in the Z direction is not accurately divided, that is, the accuracy of the height of the notch cannot be guaranteed, and the depth information of the engraved model is not Accurate processing leads to rough workmanship of the generated seals, which cannot meet people's needs for high-quality seals

[0004] The prior art also discloses a 3D printing system and method based on 2D images. The system calculates the depth of the imaging model, obtains 3D information of the environment based on the depth information, and performs 3D reconstruction. The 3D printer obtains 3D printing, because this printing method does not further process the depth information, so this printing method is only suitable for printing ordinary entities, and cannot print products with "relief" or "carving" artistic effects

[0005] The prior art also discloses a method for generating hollowed-out reliefs combined with multiple input methods. Starting from a three-dimensional model, the line drawings, rendering images, and depth maps of the three-dimensional model are sequentially obtained, and then the final hollowed-out reliefs are synthesized and generated by an optimization method. The method is based on a variety of input data. Firstly, the corresponding 3D model is established. Based on the 3D model, the line drawing of the 3D model is extracted to generate the outline of the hollow relief, and then the rendering and height map of the 3D model are extracted. If the generated 3D model has a complex structure, It is necessary to increase the amount of extraction and prolong the operation time, and there are certain defects in use.
