Image processing-based stacked paper pulp molded product quality detection method and system

The invention relates to the technical field of paper pulp molding production, and particularly provides a stacked paper pulp molding product quality detection method and system based on image processing, and the method comprises the steps: to-be-detected paper pulp molding products are stacked on a conveyor belt in groups, and a preset size range of each type of data is obtained; an infrared laser detection module is arranged at the top of the conveying belt, and the size information of rough edges, missing edges and deviated edges of each group of to-be-detected paper pulp molded products and the quality information of whether metal foreign matters are contained or not and large waste dirt are obtained through the infrared laser detection module; magnification imaging modules are arranged on the two sides of the conveying belt, camera modules are arranged, images of the magnification imaging modules are obtained through the camera modules, and counting is carried out on each group of to-be-detected paper pu
