AI Technical Summary
Technical Problem
Existing technologies make it difficult to accurately measure the clearance of wind turbines, resulting in a high risk of blade-to-tower collisions. Furthermore, traditional contact sensors affect blade structure and are costly.
Method used
Image acquisition equipment is used to acquire target images of wind turbines. Image recognition technology is used to detect the edges and tips of the tower and blades, calculate the pixel width of the tower and the pixel distance of the clearance, and determine the actual clearance value by combining the scaling ratio.
Benefits of technology
It enables accurate measurement of the wind turbine's clearance value, avoids blade-to-tower collisions, reduces the risk of equipment damage, and reduces sensor costs.

Abstract
本申请提供了一种风力发电机净空值的测量方法及装置，可以先获取图像采集设备对风力发电机拍摄得到的目标图像，接着从目标图像中检测出风力发电机的叶片和塔筒，得到塔筒的第一边缘和第二边缘以及叶片的叶尖点。接着，可以确定叶尖点所在的平面上第一边缘到第二边缘的塔筒像素宽度，并确定叶尖点所在的平面上从叶尖点到目标边缘的净空像素距离。目标边缘为第一边缘和第二边缘中距离叶片更近的塔筒边缘。在确定塔筒像素宽度和净空像素距离之后，可以根据塔筒像素宽度和净空像素距离，确定风力发电机的实际净空值。如此，可以准确地计算出风力发电机的实际距离。
