A military plotting method in three-dimensional scene

Abstract

The invention discloses a military plotting method under a three-dimensional scene, comprising a three-dimensional point military symbol plotting method and a three-dimensional function military symbol plotting method. A method for plot three-dimensional point military symbols comprises the following steps: step S11, relief processing of two-dimensional military symbols; Step S12, edge detection of the image; Step S13, drawing symbols. A 3-D function military mark symbol plotting method comprises the following steps: step S21, algorithm analysis; 22, determining an interpolation point by a variable step size interval averaging method; Step S23, determining a parameter interpolation step length l; Step S24: elevation adding. The invention realizes the real-time construction of the three-dimensional point military symbol based on the solid model and the bulletin board combination technology, combines the high abstraction of the two-dimensional symbol with the visualization of the three-dimensional symbol, and gives the combat commander infinite imagination space. At the same time, the triangulation algorithm of indefinite length interval bisection not only ensures that the nodes reduce the beauty of the curve, but also does not affect the efficiency of rendering.

Description

technical field [0001] The invention relates to a military standard plotting method, in particular to a military standard plotting method in a three-dimensional scene. Background technique [0002] The army label is a commonly used graphic symbol to represent the combat command, combat simulation and other military-related activities of the troops. According to the military situation of the enemy and the enemy, these symbols and characters are marked on the electronic map to form the combat situation and combat team of the enemy and the enemy. A series of state diagrams related to military activities, such as the shape, the determination of the head, and the weapons and equipment of the troops. The construction of the modern battlefield environment has changed from a two-dimensional flat map to a three-dimensional virtual battlefield, so it is imperative to construct a set of three-dimensional military standard symbols. [0003] 3D military mark plotting is very important f...

AI Technical Summary

Problems solved by technology

Although this method has clear tactical meaning, good visibility, and relatively simple implementation, due to the need to draw a three-dimensional symbolic cube model and the large number of military standards, it needs to occupy a large amount of memory space, takes a long time, and has poor real-time performance; 2) Dan Hagens et al. proposed another form of military standard plotting, which is to use bulletin board technology to directly display two-dimensional military standard images in the scene

This method has fast plotting speed, takes up less memory space, and has good real-time performance. However, this form of military standard is not realistic and three-dimensional, and its tactical meaning is not clear enough, and its visibility is poor.
