First, relationship between flap input and bladepitch was deduced based on the pitch kinetic equation of rigid blade.
首先根据电控旋翼的刚体桨叶变距运动方程，推导了襟翼操纵量与桨叶桨距的显式关系式。

A new measuring way different from the traditional deducting method for the Angle of bladepitch was proposed based on high-speed camera and image processing.
一种新的测量方式不同，传统的扣除方法的叶片变桨角度提出了一种基于高速摄像头和图像处理。
