The invention provides a curvature self-adaption orbit drawing method, and belongs to the technical field of aerospace and computer graphics. According to the method, through steps of data conversion point calculation, stepping sampling, a data overturning copying and orbit drawing, the sampling direction and resolution ratio are controlled, so that calculation of points to which an orbit line belongs can be quickly generated in the mode that a shape is maintained, and an information guarantee is provided for spaceflight test control. By means of the method, a quick shape-maintenance curve sample collecting method is achieved, the drawing method is used for drawing the computer orbit line, and real-time performance and accuracy of orbit drawing are guaranteed.

Description

technical field [0001] The invention belongs to the technical fields of aerospace and computer graphics, and in particular relates to a curvature-adaptive trajectory drawing method. Background technique [0002] In spacecraft flight trajectory design, flight simulation, and operation measurement and control tasks, the use of computer drawing methods to draw spacecraft flight trajectory lines is one of the key contents of aerospace parameter monitoring. The data basis of the drawing method The sampling point data acquisition of the orbit curve, the real-time performance, sampling accuracy, and data volume of different methods vary greatly. The use of computer graphics to draw track curves requires high real-time performance. Among them, the commonly used method is fixed axis coordinate incremental sampling, which is faster but has insufficient shape-preserving performance at positions where the curve changes drastically. Another method is fixed-angle sampling point, which is...

Problems solved by technology

The use of computer graphics methods to draw orbital curves requires high real-time performance. Among them, the commonly used method is to fix the coordinates of the coordinate axes and increase the sampling, which is faster, but the performance of shape preservation is insufficient in the position where the curve changes drastically.

Another method is fixed-angle sampling points, which is complicated to implement and poor in real-time performance
