The invention discloses a method for locating coal gangue based on image threshold segmentation and BLOB analysis method. The points together form a partition BLOB; use the image coordinate information of all pixels belonging to a BLOB partition to perform statistical analysis, and obtain geometric information such as the center of gravity, center, area, and area range of the BLOB partition; Select the BLOB partition with the largest area as the coal gangue target partition, and use the geometric feature information of the target partition to locate the coal gangue target. The invention can analyze the geometric feature information such as the center and distribution range of the coal gangue image, can identify and locate the coal gangue, and can be applied to the positioning in the coal gangue sorting, which is beneficial to popularization and application. |
