The invention discloses a high-noise face recognition method and device. The method comprises the following steps: acquiring a to-be-recognized image; extracting features of the to-be-recognized image through a residual building unit in a deep residual network to obtain a feature image; performing absolute value operation and global average pooling operation on the feature images in sequence to obtain a denoising threshold value of a channel corresponding to each feature image; performing soft threshold denoising on the feature image based on the denoising threshold to obtain a denoising feature; obtaining a weight value corresponding to each de-noising feature through an attention mechanism; identifying the to-be-identified image according to the weight value to obtain an identification result; according to the invention, the model can obtain the effective face features in the to-be-recognized image in a too bright environment, a too dark environment or other special and complex environments, and the recogni
