Method and device for controlling rotating speed of drum of laundry equipment and laundry equipment

The invention discloses a method and device for controlling the rotating speed of a roller of laundry equipment and the laundry equipment. The method comprises the steps that multiple images of first clothes in the roller are obtained in real time when the roller rotates by one circle; the first clothes images are processed through a trained neural network model, at least one piece of first position information of the clothes in the drum is recognized when the drum rotates by one circle, and the neural network model is used for recognizing the position information of the clothes in the drum according to the clothes images; and controlling the rotating speed of the roller according to the first position information and a preset height threshold in the roller. According to the technical scheme, the first position information of the clothes in the drum is judged through the image of the first clothes in the drum, then the rotating speed of the drum is controlled according to the first position information and th
