摘要
刚体目标的三维姿态参数是反映飞行状态的重要运动参数,获得这些参数对分析目标的运动状态,以及气动参数辨识等有着重要的价值。文中对弹的飞行姿态进行了描述,介绍了飞行姿态的光学测量方法,提出了高速摄影同步立体测量姿态的方法,并进行仿真和实验验证。
The three dimensional attitude parameters of a rigid body target are critical motion parameters that represent flight state of the rigid body. To achieve these parameters is significant valuable for analyzing moving state of the target and identifying the aerodynamic parameters. The paper describes the flight attitude of a projectile and introduces an optical measuring method used to measure this flight attitude, as well as put forward an attitude measuring method with a high-speed photography by means of synchronization and three-dimension. The method has been proved by simulation and experiment.
