【摘要】：为满足现代复合光电系统多光轴一致性的在线检测需求,提出一种基于光学自动瞄准和惯性测量的大间距多光轴夹角测量方法。利用惯性传感器提供一个准确且可移动的基准坐标系,瞄准被测光轴并测量其在基准坐标系中的单位向量坐标,再由向量坐标计算光轴夹角,以此检测光轴一致性。构建了测量系统的原理样机,并采用蒙特卡罗法对其测量不确定度进行评定。对复合光电系统中激光测距机与红外热像仪的光轴一致性进行实际检测,实验结果表明,激光发射轴与瞄准轴的一致性测量误差为24.4″,红外热像仪光轴与瞄准轴的一致性测量误差为27.0″。采用移动测量的方式,扩大了测量范围、提高了测量效率,为野外环境下大间距多光轴一致性在线检测提供了一种有效的手段。
[Abstract]:In order to meet the needs of modern online detection of composite photoelectric system of multi axis consistency, we present an optical automatic aiming and inertial measurement of large distance measurement method based on multi axis angle. Using inertial sensors provide a accurate and movable base coordinate system, aiming to be measured and measuring the shaft unit vector in the reference coordinate system in the coordinate, by vector coordinate calculation of the optical axis angle, in order to detect the optical axis consistency. Construction of the principle prototype measurement system, and the measurement uncertainty was evaluated by using Monte Carlo method. The actual detection of optical axis consistency and infrared distance of composite photoelectric system laser, the experimental results show that the consistency the measurement error of the laser emission shaft and the sighting axis is 24.4 ", the infrared thermal imager and the optical axis of the sighting axis consistency error is 27". The mobile measurement way, expand the The measurement range has improved the measurement efficiency and provides an effective means for the on-line detection of the large spacing and multi optical axis consistency in the field environment.
