The invention discloses a DNA index automatic calculation method for cervical cells, and belongs to the field of cell image processing. Due to diversity and complexity of image types, a traditional image segmentation method is single in variable parameter and cannot meet cell image segmentation precision. According to the method, the segmentation operation is divided into two parts, namely coarsesegmentation and fine segmentation, the interested cell cluster foreground region is obtained through coarse segmentation, and each cell is positioned through fine segmentation, so that the segmentation precision is better improved, and the cell diagnosis efficiency and correctness are improved. DNA aneuploidy is a biomarker in a tumor cell forming process, pathological cells are recognized by calculating DNA indexes, tiny changes which are difficult to recognize by naked eyes during cytopathy can be better described, diagnosis errors are reduced, automatic recognition is adopted in an algorithm, and the recognition e
