| description | The invention provides a generator rotor vent hole identification method and device. The method comprises the steps: marking all pictures to obtain a first picture set, obtaining the gradient and variance of each picture in the first picture set, obtaining a first parameter set, and enabling each picture in the first picture set to be corresponding to each parameter in the first parameter set; dividing the first parameter set into a training set and a test set, training the recognition model by using the training set to obtain a first model, and testing the first model by using the test set to obtain a second model; inputting a second parameter set of the real-time picture set into a second model for identification, if the identification result contains the vent hole, performing black and white binarization on the picture containing the vent hole in the real-time picture set, and if the area of a white region is greater than a proportion threshold, identifying a complete vent hole.
