In order to reduce the effect of imaging recognition error, the recognition location of projection is extended and refined, and the projection edge of sphere centre is implanted. So a pyramid is formed by radial line between the camera optical centre and the implanted point. A curved face is formed by the two pyramids and barbette sphere. To calculate the shape centre of the common section of the curved face, the shape centre is the coordinate of sphere centre.

为了降低图像识别误差的影响，对投影的识别位置进行拓展和细化，并对球心投影边界进行插值，摄像机光心与插值点连线射线形成了一个锥体，两摄像机的锥体分别与炮台球面相交形成曲面，计算两曲面公共部分的形心，即为球心位置。

The shear stress and tensile stress were increased obviously in the place of 388mm to centre of gyration of wind rotor comparing with other section where the phenomenon of stress concentration had for 1.5MW blade model.

在风速为14.6m/s时，1.5MW叶片模型风力机风轮转速达到400 rpm，但风轮风能利用系数为0.062，表明兆瓦级叶片模型与100W风力发电机不匹配。

There were the same load characteristics of 1MW, 1.5MW and 2MW blade model, which the tensile stress, shear stress and torque of section were linearly increased with increasing of wind speed; and tensile stress of all test sections of the blade was changed greatly, but shear stress was basically the same in the same wind speed. The shear stress and tensile stress were increased obviously in the place of 388mm to centre of gyration of wind rotor comparing with other section where the phenomenon of stress concentration had for 1.5MW blade model.
