In view of the inconveniences of existing visual aid systems for the blind, the method of running the image captioning model on portable mobile devices based on model pruning was discussed.Model pruning techniques and image captioning models were reviewed.An improved model pruning algorithm for image captioning model was proposed.Experimental results show that, on the premise of ensuring accuracy, the image captioning model after pruning can greatly reduce processing time and power consumption capacity, and can quickly and accurately describe environmental information and voice broadcast anytime and anywhere.

Key words: visual assisted system, image captioning model, model compression and acceleration, model pruning algorithm
