一种基于最小二乘法直升机旋翼桨叶挥舞角测量方法

摘要

为实现直升机旋翼桨叶挥舞角的测量，提出一种基于最小二乘法的测量方法。该方法使用双目视觉技术实现旋翼桨叶特征点的提取；使用最小二乘法对特征点三维信息进行处理，得到转轴方向向量和旋翼中心等参数；根据所得参数建立旋翼坐标系，并计算得到挥舞角大小。%In order to realize the measurement of helicopter rotor blade lfapping angle,a method based on least square method is proposed. This method use the binocular vision technology to realize the feature extraction of the rotor blade;processing the feature points 3D information with the least square method,and the get the parameter such as rotor direction vector and the rotor center;building the rotor coordinate system based on the parameter,and then get the lfapping angel.
