Generating method and system for satellite track

Abstract

The invention discloses a generating method and a system for a satellite track. The generating method includes obtaining satellite crossing points after leading an earth model in model space and generating a Bezier curve according to the satellite crossing points; obtaining at least two Bezier curve control points according to the Bezier curve; generating a plane which passes through a sphere center point of the earth model and the Bezier curve control points according to the sphere center point of the earth model and the Bezier curve control points; taking the sphere center point of the earth model as a center and fitting the Bezier curve control points so as to generate a Bezier curve of the satellite track on the plane; and outputting the Bezier curve of the satellite track. According to the generating method and the system, the problem of effective generation of the motion track during an animation simulation process of a satellite flight is solved, therefore track parameters are convenient to adjust, a more intuitive effect is provided, satellite motion can be better associated with, and preparations can be made for satellite animation.

Description

technical field [0001] The invention relates to the field of television digital video program production, in particular to a method and a system for generating a satellite trajectory disclosed for the simulation animation simulation of a satellite leap. Background technique [0002] With the rapid development of the field of digital animation production, various digital animation processing methods can be used to restore and simulate the movement of objects. , the digital animation synthesis technology involved in the field of digital animation processing is usually used, especially in the field of TV program production with special needs, such technology is more extensive, such as in satellite launch or satellite motion detection programs In order to enable the audience to feel the real visual effect of satellites flying in space, while simulating the outer space environment, it is more important to give correct simulation of satellite flight in space, but due to satellite ...
