The invention discloses a system for acquiring human body motion information and a method thereof. The system comprises a data processing module, a plurality of electromyographic signal acquisition modules and at least two image acquisition modules, the electromyographic signal acquisition module is used for acquiring electromyographic signal data of a user and sending the electromyographic signal data to the data processing module; the image acquisition module is used for acquiring image data of a user and sending the image data to the data processing module; and the data processing module is used for acquiring skeleton motion features of a user by using a convolutional neural network according to the image data; extracting a plurality of electromyographic characteristics of the electromyographic signal data; and determining motion information of the user according to the skeleton motion features and the multiple myoelectricity features. The skeletal motion features of the user are acquired from the image data acquired by the image acquisition module through the convolutional neural network, and the motion information of the testee can be accurately and objectively obtained in combination with various myoelectricity features acquired from the myoelectricity signal data acquired by the myoelectricity signal acquisition module.
