Resin layered interface identification method, device and equipment

The invention provides a resin layered interface recognition method, device and equipment, and the method comprises the steps: receiving an image recognition instruction, and collecting the image information of to-be-recognized resin based on the image recognition instruction; selecting a region of interest in the image information based on image segmentation; dividing the region of interest into preset equal parts from top to bottom; determining a single-channel mean value of a preset line number at the lowest edge of each equal part; counting the number of single-channel mean values greater than a layering threshold value; when the number is larger than the preset value, it is determined that the layered interface is recognized, and the preset value is smaller than the preset line number, by means of the technical scheme, the calculation amount is effectively reduced in the mode that whether the resin is the anion resin or not is judged in an equal-part mode, and therefore the problem of jamming of a proces
