As the most important communication tool between people, language is an ever-increasing demand for people to quickly switch between different languages.This study aims to develop a mobile intelligent translation system based on the Android platform, allowing users to perform multilingual translation anytime and anywhere, and to provide high-quality and accurate translation results.This paper mainly studies the mobile intelligent translation system based on the Android platform. This paper designs and implements a mobile intelligent translation system based on the Android platform, including image acquisition, preprocessing, image text recognition and translation results processing functions. Through experiments, it can be known that the online translation speed of the mobile intelligent translation system constructed in this paper is 31%, the pronunciation success rate is 99%, and the translation success rate is 98.7%, which has a certain gap with the more mature translation systems on the market.
