Title:
FITNESS EXERCISE RECOGNITION METHOD BASED ON WEARABLE SENSOR
Document Type and Number:
WIPO Patent Application WO/2021/115064
Kind Code:
A1
Abstract:
A fitness exercise recognition method based on a wearable sensor. The fitness exercise recognition method specifically comprises the following steps: step 1, obtaining an inertial sensing signal in a fitness exercise process and preprocessing the inertial sensing signal; step 2, performing window segmentation on the signal preprocessed in step 1; step 3, performing feature extraction on the signal segmented in step 2; step 4, performing normalization processing on the feature data extracted in step 3; step 5, performing feature dimension reduction on the features processed in step 4; and step 6, recognizing the features processed in step 5. According to the method, exercise information is extracted by utilizing acceleration and angular velocity signals acquired by an exercise sensor integrated in a wearable device in the process of the fitness exercise of a person, so that the recognition of the fitness exercise is achieved.
