Non-coal foreign matter detection method and equipment for conveying belt of coal preparation plant

The invention provides a coal preparation plant conveying belt non-coal foreign matter detection method and equipment, and the method comprises the steps: carrying out the image collection of coal briquettes and non-coal foreign matters on a coal preparation plant conveying belt, obtaining a plurality of target images containing the coal briquettes and the non-coal foreign matters, and forming a non-coal foreign matter detection image sample data set; constructing a non-coal foreign matter detection and recognition model, and training the non-coal foreign matter detection and recognition model through the non-coal foreign matter detection image sample data set; images of the coal preparation plant conveying belt during coal briquette conveying are obtained in real time, the trained non-coal foreign matter detection and recognition model is input, and a detection result that whether non-coal foreign matter exists on the coal preparation plant conveying belt or not is output. According to the invention, the pro
