Embodiment Construction

[0006] The top view of the target provides the design basis for the two-dimensional display of the three-dimensional track, that is, the relative spatial position information of the target is displayed: azimuth, distance and altitude.

[0007] The X-axis of the two-dimensional coordinate system represents the azimuth coordinate of the target, and the unit is ° (degree); the viewing angle range of the displayed photoelectric detector can also change according to the change of the photoelectric azimuth angle; the Y-axis represents the distance coordinate of the target, and the unit is Km; In this two-dimensional coordinate system, the entire coordinate system is divided into grids with a dotted line that is lighter in color than the coordinate axis, so that it is convenient to quickly determine the current position range of the target;

[0008] The color bar (H-axis) indicates the height value represented by the color change of the track line; the color bar divides the 1Km height...

Abstract

The invention relates to a two-dimensional displaying method for a three-dimensional flight path. The X axis of a two-dimensional coordinate system displays orientation information, and the Y axis displays distance information; a color strip of a flight path line represents height information. During implementation of the two-dimensional displaying method, coordinate conversion and modeling are greatly simplified; a space situation of a target can be easily read visually according to a height color, so that people do not feel visual spinning sensation caused by three-dimensional displaying.

Description

technical field [0001] The invention belongs to the field of computer display, in particular to a two-dimensional display method of a three-dimensional track. Background technique [0002] For a target to be displayed in the computer system, it needs to be acquired by the detection equipment and its three-dimensional spatial position information displayed by the computer system. For example: GPS global positioning system can calculate the longitude, latitude and height of the target through satellite observation. A real target in the actual environment is described by three-dimensional space information, for example: in the Cartesian coordinate system, the distance from the X, Y and Z axes relative to the origin; in the spherical coordinate system, the distance from the origin, orientation Angle and elevation angle; longitude, latitude and altitude in GPS, etc. The 3D display of the target is hollow, the inter-coordinate conversion is complicated, the model establishment i...
