| 车载火箭弹在发射过程中，定向管的角运动会对火箭弹发射造成初始扰动，进而影响其发射精度。针对这种情况，本文提出一种非接触式定向管角运动参数动态测量方法。介绍了系统组成，给出了基于PRY角刚体空间位姿描述和齐次变换思想的角运动参数解算模型，阐述了光斑信息提取及数据处理过程。利用三维建模软件进行了原理性仿真验证，初步证明了该测量方法稳定可靠，精度较高，可用于火箭弹武器试验中。 |

| Angle movement of directional tube may cause the initial disturbance in the launching process of multiple rocket launching systems (MRLS), and then affects the precision of movement. In view of this situation, a dynamic non-contact measuring method is proposed. In this paper the system composition is introduced, the calculation model of angle motion parameters is given, which is based on the description method of space attitude with PRY angle and homogeneous transformation, and the information extraction of light spots and the data processing are elaborated. This method is proved to be stable and reliable with high precision by means of the original rational test with three-dimensional modeling software, and it can be used in rocket weapons tests. |
