Printing and dyeing identification method in textile printing and dyeing process

The invention relates to the field of data recognition, in particular to a printing and dyeing recognition method in a textile printing and dyeing process, which comprises the following steps: acquiring a textile grey-scale map and all matching point groups; the deformation quantity of each matching point group is obtained through angular point matching; fitting a linear model of each area according to the deformation quantity; obtaining a deformation coincidence rate based on single-region analysis by using the fitting precision of each linear model; obtaining a texture deformation rule curve caused by deformation according to the deformation parameters of each linear model; a deformation coincidence rate based on overall analysis is obtained according to the change condition of adjacent points on the curve, and then a texture deformation coincidence rate is obtained; judging whether texture deformation caused by deformation exists in the textile or not according to the texture deformation coincidence rate;
