Gait recognition method based on inertial sensor

The invention belongs to the field of the body area network and relates to a gait recognition method based on an inertial sensor. The method includes four phases. In the data acquisition phase, four sensor nodes attached to legs of a testee and a sensor node attached to the waist of the testee are used to acquire motion angular speeds, accelerations and magnetic field strengths of the legs and waist of the body of the testee and wirelessly transmit data to a base station, and then the data are transmitted to the upper computer for processing. In the period dividing phase, gait periods are divided according to angular speed change curves of the shanks so as to obtain segment data corresponding to gaits. In the feature extraction phase, waveform features and behavioral features are extracted from the segment data and used to describe fluctuation of sensor signals and sport performance of gait behaviors. In the gait classification phase, the gait features are transmitted to a classifying model, types of the gaits are acquired by computing, and thus gait recognition is achieved. The method is suitable for use in gait recognition in the fields, such as sports training, medical care and game design.

Sports training monitoring system

The invention discloses a sports training monitoring system. The sports training monitoring system comprises a video data collecting module, a vital sign collecting module, a motion state collecting module, a man-machine operating module, a data processing module, an action standard judging module, an instruction outputting module, a central processor, a three-dimensional model generating module and a physical state assessment module. According to the sports training monitoring system, video collecting is conducted by adopting panoramic video collecting, so that the video monitoring coverage is widened; the body and motion conditions of athletes are monitored through different sensors with Beidou modules, analogue simulation is conducted on monitored data through a three-dimensional model, and therefore a monitor can more comprehensively and accurately conduct monitoring and data analysis and assessment on the motion process; meanwhile, a physical condition assessment function, the standard action judging module and the instruction outputting module are achieved in the whole monitoring process, and therefore the training efficiency is greatly improved; in addition, three-dimensional putting of instructions can be conducted through the three-dimensional model generating module, and therefore convenience is brought to study of the athletes.
