摘要
风力机叶片是风力机接收风能的关键构件。作者采用激光投影法实现叶片型面的非接触全型面测量。对叶片视觉图像进行预处理 ,提高测量系统对图像的识别精度。利用数学方法构造叶片翼型曲线函数 ,设计动态视觉跟踪算法加快图像处理速度 ,提高测量效率。提出智能化机器视觉快速测量策略。对叶片加工的自动化和数字化具有一定的意义。
The blades are the key parts for the wind machine to receive wind energy. The blade shape was measured using non contiguously method of laser projection. The image of blade vision is pro treated for improving identify precision of the system image.The aerofoils curve functions were created by using mathematic method to build a databank of blade aerofoils.The vision track arithmetic was designed for the system to identify the image fleetly. The policy of fleetness measure is put forwarded to form intellectualized vision. All of these are significant for blades to realize their robotized and digital manufacture.
