Fitness auxiliary system based on motion capture

Abstract

The invention relates to a fitness auxiliary system based on motion capture, which is used for assisting a user to correct a running posture and comprises a running machine; a matrix light source; an imaging unit; an image acquisition unit; and a computing terminal which is in communication connection with an image acquisition unit and at least comprises a processor, wherien the processor is configured to execute an executable program, the executable program at least comprises a frame extraction unit, an optical flow feature extraction unit and an LSTM (Long Short Term Memory) unit, the frame extraction unit is configured to perform image frame extraction on the video flow data. the optical flow feature extraction unit is configured to perform optical flow feature extraction on the image frame to generate a frame optical flow feature, the LSTM unit is configured to calculate a running posture score frame by frame according to the frame optical flow feature, and the LSTM unit is pre-trained by an Image Net standard running image library, the running posture score is in positive correlation with the running posture standard degree of the user. According to the fitness auxiliary system based on motion capture, the precision degree of motion can be predicted by using the optical flow features and the LSTM model.

Description

technical field [0001] The invention relates to an information processing method, in particular to a motion capture-based fitness assistance system. Background technique [0002] With the progress of social civilization, people increasingly hope that they can have a more beautiful figure while being healthy. And fitness exercise is one of the important ways to achieve this goal. Among many fitness exercises, running is relatively free from time and place restrictions and is easy to participate in. Therefore, in recent years, it has increasingly received the favor of urban white-collar workers. But with the continuous in-depth understanding of many participants, most people will find that running is not as simple as it seems on the surface. First of all, everyone should formulate a reasonable amount of exercise according to their own physical characteristics, so as to avoid excessive exercise during running, which will cause knee joint wear and tear and cause knee joint pai...
