Three-dimensional space situation characterization method and device of height information enhanced Mercator map

Abstract

The invention relates to a three-dimensional space situation representation method and device of a height information enhanced Mercator map, computer equipment and a storage medium. The method comprises the following steps: by acquiring Mercator projection map data, establishing a longitude and latitude high-altitude isometric projection rectangular coordinate system by taking a Mercator projection map as an XY plane, forming a space situation three-dimensional representation space, directly acquiring or calculating through a preset formula to obtain a longitude value, a latitude value and a height value of a to-be-represented object in a geographic coordinate system; and obtaining an isometric projection coordinate value in the longitude direction and an isometric projection coordinate value in the latitude direction of the to-be-represented object in the longitude and latitude high-altitude projection rectangular coordinate system through a preset conversion relation, setting a height value, and drawing the to-be-represented object in the spatial situation three-dimensional representation space by adopting a visualization technology. According to the method, the distance relation illusion between the spacecrafts caused by height loss can be avoided, and particularly, the method has a very good effect in the aspect of representing the relation between the synchronous orbit spacecrafts and the spacecraft ground.

Description

technical field

[0001] The present application relates to the technical field of three-dimensional representation of space situation, in particular to a method, device, computer equipment and storage medium for three-dimensional space situation representation of height information enhanced Mercator map. Background technique

[0002] The space situation involves space moving entities such as artificial satellites, the sun, and the moon, ground entities such as measurement and control stations, ships, and vehicles, air moving entities such as aircraft, and the spatial geometric relationship and changes between entities. Since the movement scales of artificial satellites, the sun, and the moon are much larger than the scope of human naked eye observation, choosing an appropriate coordinate system and projection relationship, and visually displaying the entities involved in the space situation and their relationships through computer visualization technology are crucial to the de...
