Deep-learning-based image recognition of ancient musical score of Guqin

The art of Guqin is an ancient musical art form in China. The technological revolution in the high-tech era has brought new opportunities and challenges to the art of Guqin. This paper briefly describes the research content of digital protection of Guqin ancient score, aiming at the characteristics of complex combination of scores and changeable writing styles faced by optical music score recognition of ancient score, puts forward the engineering scheme of information retrieval of ancient score music based on multi-target detection and combination strategy, creates an object detection model of deep learning, and uses the ancient score of "Magic Secret Score". The words in the ancient musical score are intelligently detected, and the experiment shows that the ancient musical score recognition model based on deep learning has better detection accuracy.
