基于TLS的靶板穿孔特征识别提取方法
靶板穿孔 点云处理 三维激光扫描 特征识别提取
2021/2/26
为了能够更好地研究战斗部的破片毁伤效应，对靶板的毁伤效果进行更加快速、准确地评估，采用三维激光扫描技术进行快速靶板毁伤效果评估。利用相位式三维激光扫描仪获得爆破前后的战斗部及靶板点云数据，通过原始阵列式点云的内部点间关系及变化情况，识别爆破后的靶板穿孔特征，同时统计穿孔特征并计算飞散角等信息。数据验证结果表明，该方法能够有效输出爆破特征的位置、形状及抛射方向，并通过统计值及分布计算为靶板毁伤效果评...
为提高捷联寻北仪在动态干扰下的寻北精度,同时解决寻北过程中需要人工调平而耗时较长的问题,结合全姿态多位置寻北模型,提出采用小波去噪处理陀螺输出信号和总体最小二乘寻北算法的组合滤波方法。针对硬阈值函数和软阈值函数去噪的局限性,使用改进阈值函数处理陀螺噪声,能够更好滤掉动态干扰;根据多位置寻北解算特点,创新性引入总体最小二乘寻北算法,有效补偿了寻北仪的静态误差。仿真数据和实验结果表明，该组合算法能显著...
