Human body action and body surface deformation capturing method and corresponding modular wearable device

The invention discloses a human body action and body surface deformation capturing method and corresponding modular wearable device.The human body action and body surface deformation capturing method comprises the steps that (1), a modular wearable device rapid construction method is adopted, specifically, body shape data of a user wearing part are collected, a modular wearable IMU sensor network is constructed, and the body shape data of the user wearing part are stored in the modular wearable IMU sensor network; personalized wearable equipment wearing schemes are generated for different users; making and assembling an IMU sensor-based modular wearable device according to the wearing scheme, and wearing the IMU sensor-based modular wearable device on a specific part of a user; and (2) a pose self-sensing algorithm: processing IMU sensor data from a wearable equipment data processing module to obtain user actions and body surface deformation. According to the method, personalized human body data are fully con
