Material flattening method and device

The invention relates to the technical field of image processing, in particular to a material flattening method and device, and the flattening method comprises the steps: obtaining material images of different visual angles, carrying out the image enhancement, feature extraction and feature matching, accurately recognizing materials in the images of multiple visual angles, and obtaining material regions in the images of multiple visual angles; a material three-dimensional model is established based on the material area information of the multiple visual angles, and a to-be-flattened material area is determined; according to the distance between the to-be-flattened material area and the inner wall of the mold box, determining the sequence of performing flattening treatment on the to-be-flattened material area, and sequentially performing flattening treatment on the to-be-flattened material area according to the sequence; the flattening method is good in flattening effect, high in flattening efficiency and stab
