摘　　要：针对海上舰船补给活动中船间相对位姿监测的需求,详细介绍了船间水平间距及舷偏角的测量。采用非接触式光电跟踪瞄准结合激光测距方法,对目标进行识别测量,结合船自身姿态测量获得最终测量结果。根据测量原理,建立了动平台下的计算模型。采用四元数的方法进行了公式推导,应用蒙特卡洛法对测量公式进行数据仿真,并对测量误差进行了估算。仿真结果表明水平间距测量精度优于15 mm,舷偏角精度优于1',通过实验室实际测量,验证了这一结果。Aiming at the requirement for relative pose monitoring during the course of underway replenishment, a measuring method of the horizontal distance and the declination angle is proposed in this paper.The target recognition and measurement are realized with the method of non-contact optical tracking and targeting and laser ranging.The fi-nal result is obtained by calculating with the data of pose measurement.A mathematical model is built with the meas-urement principle.The formulas are calculated with the quaternion method.The measurement processes are simulated and the errors are estimated by using Monte Carlo method.The simulation results show that the horizontal distance precision is better than that of 15 mm, declination angle precision is better than 1′, and the results are verified with the measurement in lab.
