description The invention provides a method for detecting a fabric surface hair ball area. The method comprises the following steps: S10, preprocessing a sample image of a to-be-detected fabric; s20, carrying outimage enhancement on the preprocessed image by adopting a logarithm change method; s30, performing frequency domain transformation and filtering on the to-be-detected sample image after image enhancement, and calculating an extreme point to determine the radius of a frequency spectrum recovery region to obtain a filtered and recovered image; s40, performing inverse Fourier transform and contraststretching on the image after filtering recovery to obtain a coarse segmentation image of a fabric surface hair ball area; s50, adopting a level set segmentation algorithm based on fuzzy clustering and a lattice Boltzmann method to carry out fine segmentation on the coarse segmentation image of the fabric hair ball area; and S60, screening and fusing the fine hair ball segmentation area accordingto a morphological method t
