Abstract

In view of the disadvantages of current methods in gait recognition, such as motion signal segmentation, inconsistent sensor orientation and low similar recognition accuracy, this paper proposed a novel gait recognition method based on inertial sensor and AdaBoost algorithm. First of all, based on the scale-space technique, this paper proposed a robust gait detection method to classify the signal into motion samples in order to cope with the dramatic changes in motion speed or intensity. Then, it applied the position compensation matching algorithm to correct the tilt of the sensor, so as to solve the problem that the sensor orientation was inconsistent. Finally, in order to improve the recognition accuracy, it adaptively selected the motion characteristics based on AdaBoost algorithm, and performed the discriminant analysis to complete the recognition. It carried out five similar gait motion recognition experiments. The results show that the proposed algorithm has high accuracy.
