足球弧线直接任意球运动轨迹的建模与仿真算法

The Curve of a Direct Free Kick in a Football Curve Modeling and Simulation Algorithm

在梳理文献资料的基础上,针对弧线球进行了抛射角、旋转、空气阻力等因素的分析,分解了足球在飞行中的受力过程.在不考虑其它次要因素的条件下,建立了三种模型.分析了能射出此弧线球的"热区",给出了弧线球的最佳射球区域.对足球运动轨迹进行仿真,通过输入参数再现弧线球的飞行轨迹,客观判断足球是否命中球门.

Based on the analysis of literature data, the curve ball is analyzed, the projection angle rotation, air resistance and other factors; the decomposition of football in the process of stress during the flight; without considering other secondary factors, established three models, analysis of this curve can shoot the ball ＂hotspots＂ the best shot, the ball arc region is given, and the simulation of football trajectory, trajectory reproduction curve ball through the input parameters of the objective, determine whether the football goal.
