摘　　要：针对视觉式头部姿态测量系统存在编码特征点安装空间需求大的问题,设计一种结构简单、需求空间小的瞄准线测量方法。使用定位摄像机拍摄头盔上的编码特征点图像,计算机对图像进行解析和计算,结合正交迭代(OI)算法解算头部姿态。根据编码特征点随意布局特点进行了多组多次的仿真分析,仿真数据表明此方法是合理、有效的,利用小空间布局的编码特征点可以解算出高精度瞄准线。In computer vision head pose measurement system,large space is needed for the installation of coded feature points.To solve the problem,a new method is put forward for the measurement of the Line-of-Sight(LOS)with a simple structure as well as smaller installation space.The method uses the positioning cameras to capture the picture of the coded feature points on the helmet,and a computer for image calculating and analyzing.The head pose is obtained finally with the Orthogonal Iterative(OI)algorithm.Based on the characteristic of the feature points,we conducted a series of simulation analysis.The simulation results proved the rationality and the validity of the method,and showed that a high-precision LOS can be obtained by using the coded feature points distributed within a smaller space.
