Problems solved by technology

[0007] To sum up, these methods are subjective and fuzzy methods to determine the weight, and the weight coefficient is often affected by human factors, which is not conducive to the fairness of the final evaluation result, which reduces the credibility of the final evaluation result and affects the virtual reality. Scheme selection and key index optimization for visual simulation of marine battlefield environment

Embodiment Construction

[0067] Taking the marine battlefield scenes drawn by two different methods of OpenSceneGraph (OSG for short) and Vega Prime (VP for short) as an application example of this method, the 3D visualization effect of the virtual marine battlefield is evaluated.

[0068] OSG is developed using OpenGL technology and provides a set of application program interface API based on C++ platform, which allows programmers to create high-performance, cross-platform interactive graphics programs more quickly and conveniently; the bottom layer of VP uses OpenGL technology and uses Lynx Prime GUI The tool uses the cross-platform scene graph API based on VSG, allowing users to quickly configure with graphical tools and accurately develop real-time 3D scenes.

[0069] according to Figure 2-5 It can be seen that the three-dimensional visualization effects of the virtual ocean battlefield scene established by the two schemes are not the same, and the core index system reflected in the visualization...

Abstract

The invention provides a virtual ocean battlefield 3D visualization effect assessment method, and belongs to the technical field of virtual reality. Firstly, the hierarchical relation of indexes is assessed through the analytic hierarchy process according to the virtual ocean battlefield 3D visualization effect, and the subjective weight reflecting an expert knowledge base is obtained through qualitative and quantitative analysis; the objective weight is determined through the difference drive principle according to the variation degree of the indexes in index sets and the degree of influence on other indexes. The two methods are combined so that the insufficient data volume caused by objective empowerment can be avoided and randomness of subjective empowerment can also be overcome, and the evaluation result is more objective and reasonable. Besides, game theory weight sets become consistent and transigent between the subjective weight and the objective weight, the sum of deviations between the mixed weight and each weight is the smallest, and therefore weight optimization is achieved. Finally, aggregation of the indexes and the weights is achieved by means of double-base-point multi-attribute decision making, closing to an ideal solution and keeping away from a negative ideal solution are used as criterions for evaluating various feasible programs, and a virtual ocean battlefield simulation system is built at last.

Description

technical field [0001] The invention belongs to the technical field of virtual reality, and specifically relates to a method for evaluating the three-dimensional visualization effect of a mixed-weighted ocean battlefield. Background technique [0002] In order to accelerate the development of my country's navy informatization and modernization, high-quality naval combat training has become the focus of improving the overall combat capability of the navy. However, due to the increasing scientific and technological content of weapons and equipment, the increasingly complex structure of the confrontation system, and the complex and changing marine environment, it takes a lot of money and time to conduct combat training in an actual combat environment, which greatly restricts the development of my country's navy informatization and modernization. In this context, the visual simulation technology of the virtual ocean battlefield has become an important means to break through this...
