Blade tip speed calculation method and related equipment

The invention discloses a blade tip speed calculation method and related equipment, and the method comprises the steps: firstly obtaining a blade tip motion image through the equipment, processing the obtained blade tip motion image, obtaining a difference image according to the blade tip motion image, carrying out the threshold segmentation of the difference image, and removing the noise of the image after the threshold segmentation; the projection point of the blade tip on the tower drum can be obtained through the step, the blade tip position in the unit operation state can be accurately calculated, the blade tip speed is obtained according to the noise-removed image, the blade tip speed detection means implemented on the ground has natural convenience and accuracy, the blade tip speed result can be conveniently and effectively measured in a fixed coordinate system, and the method is suitable for large-scale popularization and application. The device ensures high resolution and precision, is convenient and
