Embodiment Construction

[0044] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0045] Through the research of the applicant, it is found that the drawing efficiency of the existing military plotting method is low, and the drawing effect is not beautiful. For the symbol of smoothness, a symbol will generate a considerable number of triangles, which seriously affects the drawing efficiency. On the other hand, after the symbol is enlarged, the polyline segment fitted by the Bezier curve can be clearly seen, and the drawing effect is poor.

[0046] In order to solve the above problems, the embodiment of this application improves a closed symbol drawing method, please refer to figure 1 , figure 1 It is a schematic flowchart of a closed symbol drawing method provided in the embodiment of this application, and the specific steps of the method can be as follows:

Abstract

The invention provides a closed symbol drawing method and device, electronic equipment and a storage medium, and relates to the technical field of image processing. The method comprises the followingsteps: generating a skeleton point information set of a closed symbol object; generating a Bessel curved surface triangle set and an internal triangle set for filling the closed symbol object based onthe skeleton point information set; obtaining a Bessel curved surface Mesh set based on the Bessel curved surface triangle set, wherein Mesh is a model grid in a drawing tool; obtaining an internal triangle Mesh set based on the internal triangle set; drawing a Bessel curved surface triangle graph based on the Bessel curved surface Mesh set through a graph processor; and drawing an internal triangular graph based on the internal triangular Mesh set through the graph processor. Internal triangle and Bessel curved surface triangle processing is performed on the closed symbol so that the anti-aliasing effect of the edge of the broken line of the closed path can be enhanced, and thus the drawing quality of the closed symbol can be enhanced.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular, to a closed symbol drawing method, device, electronic equipment and storage medium. Background technique [0002] With the rapid development of information technology, military informatization has become the mainstream direction of the development of military equipment in the world. Countries have invested a lot of resources in the direction of electronic and informatization of military equipment to enhance their military deterrence against other countries. Among them, combat plotting is an important development direction of military equipment informatization. The combat plotting system is an important part of the battlefield situation and military command automation. It is an important means to reflect the battlefield situation and environment. It is widely used in battlefield monitoring, Combat command, situational deduction, etc. [0003] At present, the draw...
