摘　　要：针对头盔瞄准线快速、精准测量的要求,研究一种全新的综合瞄准线测量方法。在电磁瞄准线测量基础上,增加微惯性测量技术,实现头部姿态的高精度、快速、实时测量。通过卡尔曼滤波算法以及微惯性器件零偏估计,将电磁和惯性测量技术融合在一起进行综合瞄准线测量。根据瞄准线测量原理建立有效的数学模型,并用实物搭建实验平台进行测试和验证。实验结果表明,惯性和电磁综合瞄准线测量技术可以快速、有效地计算出高精度瞄准线。Aiming at the requirements for fast and precise positioning of helmets in the modern warfare the paper puts forward a new integrated LOS measurement method.Based on the electromagnetic pose measurement the inertial positioning method is added to realize fast real-time and high-accuracy head pose measurement.By using the Kalman filtering algorithm as well as the IMU zero bias estimate the method combines the electromagnetic with the inertial method for integrated LOS measurement.An effective mathematical model is established according to the principle of LOS measurement and an experimental platform is set up for testing and verification.The results show that the algorithm can effectively complete the high-precision measurement of the helmet posture.
