Electronic device and identification method for identification music score image

Abstract

The invention discloses an electronic device and identification method for identifying a music score image. The electronic device includes a housing, a sound part, a mainboard which is disposed inside the housing, and an image scanning part which is arranged at a first end part of the housing. The mainboard is provided thereon with a master control circuit and a sound card circuit and a power supply circuit which are both in electrical connection to the master control circuit. The method includes the following steps: a camera acquiring a to-be-processed music score image and transmitting to the master control circuit; the master control circuit identifying the to-be-processed music score image to identify each complete note; the master control circuit, based on the identified complete notes, transmitting corresponding sound digital signals to the sound card circuit which converts the sound digital signals that are received to playable analog signals and transmitting the analog signals to the sound part for play. According to the invention, the electronic device addresses the problems of separation between an image acquisition module and an identification module and using difficulty of prior art. The method, by cascading a note classifier and a convolutional neural network to identify notes, is advantaged by fast identification speed and high identification precision.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to an electronic device and a recognition method for music score image recognition. Background technique [0002] Image recognition refers to the technology of using computers to process, analyze and understand images to identify targets and objects in various patterns. [0003] The music score image recognition device in the prior art includes an image acquisition module and a computer. The image acquisition module collects the image data of the music score by taking pictures or scanning the music score, and inputs it into the computer. The image data collected is processed by the identification module in the computer Analyze and identify. [0004] However, the application of the above music score image recognition device has the following technical problems: the image acquisition module is separated from the recognition module, and it needs to rely on a computer to work...
