Abstract

The invention discloses a determination method and device for an abnormal material removal area and a material sorting method and equipment. The method comprises the steps: collecting a material image, and performing abnormal material recognition on the material image to obtain abnormal pixel points of an abnormal material; according to the abnormal pixel points, determining target pixel points, wherein the target pixel points are located on the sides, close to the center of the abnormal material, of the abnormal pixel points; and determining a removal area of the abnormal material according to the target pixel points. According to the determination method for the abnormal material removal area, the removal area of the abnormal material is determined according to the target pixel points of the abnormal material, the removal area can be closer to the center of the abnormal material, the abnormal material is removed according to the removal area, the removal is more accurate and effective, and the removal rate of abnormal materials is effectively improved.

Description

technical field

[0001] The invention belongs to the technical field of material sorting, and in particular relates to a method and device for determining an abnormal material rejecting area, a material sorting method and equipment. Background technique

[0002] In related technologies, when materials are sorted, abnormal materials must first be identified to obtain abnormal areas, and a rejection area is determined according to the abnormal areas, and then abnormal materials are removed according to the removal areas. In the process of realizing the present invention, the inventors have found that there are at least the following technical problems in the related art: when the abnormal area is close to the edge of the material, the determined rejection area is usually also close to the edge of the material, making it difficult to remove the abnormal material. will decrease.

[0003] Taking rice sorting as an example, such as figure 1 As shown, the dark dot in the box is th...
