For a long time, due to the hidden barriers between the music and translation majors, foreign works have faced a shortage of language materials and insufficient attention ("ethnic music"), which has become a major weakness in their external dissemination. In order to help the national music go global, this study discusses the research status of the translation and introduction of national music from an interdisciplinary perspective. The image enhancement algorithm based on machine vision removes the noise of the national music note image, so that the translator can more accurately translate the national music culture into different language texts, and facilitate the export to countries. Later, in order to keep up with the pace of globalization, it is necessary to apply various intelligent media platforms in the Internet era to realize the international dissemination of national music culture, and take an important step in the “translation” of national music.
