Summary: | The invention belongs to the technical field of wind driven generators, and provides a rotating speed prediction method and system for a vertical-axis small wind driven generator, and the method comprises the steps: obtaining an operation video of the small wind driven generator; performing clipping preprocessing and resolution reduction preprocessing on the running video; decomposing and numbering the preprocessed operation video to obtain a static graph with a number; feature color extraction is carried out on the static image; calculating the feature color area of each static picture, and drawing a corresponding curve of the feature color area according to the number of the static picture; according to the number of interval frames between adjacent wave crests in the curve, obtaining a rotating speed predicted value of the small wind driven generator; based on feature color recognition, the purpose of predicting the rotating speed of the small wind driven generator is achieved, the problem that rotating sp |
