Example Embodiment

[0017] figure 1 Shows the implementation flow chart of the present invention. The steps in the figure are:

[0018] a. Use laser scanning equipment to obtain digital models: through the three-dimensional laser scanning system, set the scan size, range, etc., you can simply and quickly complete the scanning and acquisition process of the template, and input the digital relief data into the computer;

[0019] b. Rebuild the base surface of the relief model;

[0020] c. Solve the height domain based on the base surface, and extract the relief from the background surface using the double Gaussian mixture function;

[0021] d. Combine the following operations such as movement, zoom, rotation and non-rigid deformation to realize the editing of digital relief;

[0022] d.1 Set and move the control handle of the relief, propagate the movement to each vertex of the relief, nonlinearly solve the constraint functions such as edge length and height preservation, adjust the position of the vertex, ...

Abstract

The invention discloses a design method of a digitalized relief, and the method comprises the following steps: obtaining digitalized relief data through a laser scanning device, and extracting the relief from a background surface to directly finish an the preliminary modeling of the relief; and using an editing tool to modify the position and shape of the relief, and then integrating the relief with the background surface to realize the design process of the digitalized relief. By using the design method, the undue dependence on the manual skill is reduced, the labor cost is reduced, plenty of time is saved, and the design period of the digitalized relief is shortened. The design method has the advantage of repeatability in design.

Description

technical field [0001] The invention belongs to the technical field of computer graphics and industrial design, in particular to a digital relief design method. Background technique [0002] Relief shows the low-level details on the surface of the model. It is the product of the combination of sculpture and painting. It uses compression to process objects, and uses perspective and other factors to express three-dimensional space. Reliefs are generally attached to another object (base surface) and are widely used to decorate and identify man-made objects, such as trademarks on commodities, engravings on coins and porcelain, and decorations on buildings. At present, the production of reliefs is a time-consuming and laborious work that requires skilled engravers to complete. With the maturity of computer numerical control processing technology, more and more numerical control processing equipment can be applied to the actual production of reliefs, such as numerical control eng...
