摘要
利用加油锥套的位置和尺寸信息建立Kalman滤波方程,结合加油对接过程中锥套的运动特点设置模型参数,并引入目标遮挡系数实现参数的自适应调整,对锥套的运动进行状态估计,再通过改进的霍夫梯度法采集观测值对估计值进行修正。实验结果表明,本文研究的算法在工作范围内能够实现对锥套的稳定跟踪,特别是当锥套发生部分遮挡时具有较好的持续跟踪能力,对背景变化具有较好的适应性。
The information of drogue containing position and size are used to establish Kalman filter equations.The model parameters are set considering drogue′s motion features in refueling process and the object occlusion coefficient is introduced to complete the parameters′adaptive adjustment.The next-time states of moving drogue are estimated by the model and the estimation is corrected by observation.The experimental results show that the algorithm can track the drogue stably in work distances.When non-target moving objects appear in the images or the drogue is obscured,the algorithm still has the ability of continuous tracking.
