Description
Technical Field
The invention relates to the technical field of geographic information systems and military plotting systems, in particular to a method and a device for drawing a simulation situation entity military standard.
Background
The Level of detail (LOD) multi-Level of detail technology refers to determining the resource allocation of object rendering according to the position and the importance of the node of an object model in the display environment, and reducing the number of faces and the Details of non-important objects, thereby obtaining high-efficiency rendering operation.
The Geographic Information System (GIS) provides various spatial and dynamic Geographic Information in real time by using a Geographic model analysis method based on Geographic space, and is a computer technology System for Geographic research and Geographic decision-making. Its basic function is to convert tabular form data (whether it comes from a database, spreadsheet file, or directly entered in a program) into a geographic graphic display, and then to browse, manipulate, and analyze the display results. The display range can be from intercontinental maps to very detailed block maps, and the display objects comprise population, sales, transportation lines and other contents.
In the existing simulation system, in order to visually display an entity in a simulation scene, a map is usually used as a background, and in combination with geographical position information of the entity, entity primitives are drawn at a position corresponding to the map, so as to meet the requirement of a user for visually knowing the battlefield situation. For example, the geographic information system is utilized in the United states to simulate the mobility of troops and vehicles, estimate the diffusion range of chemical weapons, simulate the effect of smoke shielding battlefield, provide the point positions required by water source detection, evaluate the influence of terrain on the weapon performance, and provide decision basis for military operations. When the simulation scale is gradually increased, the scale of an entity to be centered may be changed from several to ten thousand, and to visually present a large-scale scene, it may involve drawing primitives of ten thousand entities on a map, which may have two consequences:
(1) A large number of military standard piles exist at the position where the entity is densely distributed, so that the attractiveness is affected, when the quantity of entity primitives reaches a certain scale, a user does not need to distinguish the quantity by naked eyes, and the quantity of the entities cannot be accurately identified by the piled primitives;

Graphic elements have definite position coordinates, different graphics have various topological relations, and geographic information system data describes the elements and the relations among the elements.

Drawing graphics may be through invoking some graphical drawing three-way library interfaces, such as Qt, for example, and the invention is not limited.
S2, acquiring entity position information in the planning, and converting geographic coordinates into entity military standard map coordinates by combining the map range of the simulation situation entity military standard map and the entity geographic position information to obtain simulation position information of each entity in the current simulation situation entity military standard map; the entity is represented by entity primitives in a simulation situation entity military standard map;

Optionally, the map range of the entity military standard map is obtained, and geographic information system data is obtained and loaded; drawing within the range of the entity military standard map by using the geographic information system data to obtain an entity military standard map base map, wherein the drawing comprises the following steps:
acquiring and loading geographic information system data; the geographic information system data comprises graphical elements including point elements, line elements, and face elements, the graphical elements having explicit position coordinates;
and processing the graphic elements by using a three-party library interface for graphical drawing, drawing various shapes representing national boundaries, provincial boundaries, rivers, mountains and lakes, and finishing the drawing of the entity military standard map base map.
Optionally, obtaining entity location information in the scenario, and performing conversion from a geographic coordinate to an entity military standard map coordinate by combining the map range of the entity military standard map and the entity geographic location information to obtain simulation location information of each entity in the current entity military standard map, including:
acquiring the position information of the entity in the plan, wherein the position information of the entity is the geographical coordinate of the entity;

Optionally, the conversion between the geographic coordinates, the longitude and latitude coordinates, and the screen coordinates (here, the screen coordinates are the coordinates of the ground map of the entity military standard in the present invention) is as follows.
The geographic coordinate definition rule is:
the X-axis (representing longitude) increases to the right and the Y-axis (latitude) increases upward;
the screen coordinate definition rule is:
the X axis is increased in a right increasing way, and the Y axis is increased in a lower increasing way;
the geographic coordinates differ from the screen coordinates only in that the Y-axis increment direction is reversed.
Knowing the height (y) and width (h) of the screen, the area range of geographic coordinates is (maxlon, minlon, maxlat, minlat); the longitude and latitude represented by each pixel can be calculated by the formula:
scaleX = h/((maxlon-minlon) 3600) - - -longitude seconds represented per pixel on X axis
scaleY = Y/((maxlat-minlat) × 3600) - - -latitudinal seconds represented per pixel on the Y-axis
The coordinates of any point (lon, lat) on the geographical coordinate area on the screen are:
screen X = lon 3600/scaleX-screen coordinate X-axis coordinate
screen Y = lat x 3600/scale Y-screen coordinate Y-axis coordinate
minx = minlon 3600/scaleX- - -leftmost end to the left of the region
minY = minlat 3600/scale Y- - -area on top of it
When the geographic range area occupies the whole screen, the formula of any point in the area is calculated by using two parameters of screen X and screen Y:
X＝screenX-minX＝(lon-minlon)*3600/scaleX
since the direction of latitude is opposite to the Y-axis of the screen
screenMaxlat＝(mxlat-minlat)*3600/scaleY
screenlat＝(lat-minlat)*3600/scaleY
Y＝screenMaxlat-screenlat＝(maxlat-lat)scaleY
The formula for converting longitude and latitude into screen coordinates is as follows:
X＝(lon-minlon)*3600/scaleX
Y＝(maxlat-lat)*3600/scaleY
the formula for converting the screen coordinate into the longitude and latitude coordinate is as follows:
lon＝X*scaleX/3600+minlon
lat＝maxlat-y*scaleY/3600

assuming that the coordinates of the entity primitive a in the entity military standard map base are (x 0, y 0), the coordinates of the entity primitive b in the entity military standard map base are (x 1, y 1), and the Distance calculation formula between the entity primitives a and b is as follows:
Distance＝0.5[2(x1-x0)+2(y1-y0)]
the distance threshold value delta is set by an operator according to experience freely, the larger the value is, the more military marks are not drawn, the higher the drawing efficiency is, and the smaller the drawing efficiency is. But the larger the size, the better the size, and the smaller the size, the military personnel need to grasp the device by themselves according to the needs.
