Abstract

The embodiment of the invention provides a human body action mapping method and device, computer equipment and a storage medium, and the method comprises the steps: in the embodiment, reading inertial data from a plurality of inertial measurement units, enabling the plurality of inertial measurement units to be attached to a body part of a user, and enabling a part of two adjacent inertial measurement units to be separated from a body joint of the user, and fusing the inertial data into postures of the inertial measurement units in the space, calculating joint angles of the body joints according to the postures corresponding to two adjacent inertial measurement units, mapping the joint angles to machine joints of the robot, driving the robot to move until the adjacent machine joints reach the joint angles, calculating the joint angle of the body joint by directly calculating the posture of the inertial measurement unit, and mapping the joint angle to the machine joint of the robot, so that the operation is simple, the calculation complexity is reduced, the calculation frequency is improved, the following degree of the robot is high, the corresponding speed is high, and the robot can be guided to realize various flexible actions.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of automation, and in particular to a human body action mapping method, device, computer equipment and storage medium. Background technique [0002] With the development of science and technology, learning human actions, mapping human actions to robots, and having the robots execute the actions can be widely applied to multiple business scenarios. [0003] For example, in the business scenario of firefighting and disaster relief, fire-fighting robots can help firefighters carry out rescue work remotely; surgery or virtual surgery. [0004] The methods of extracting human motion mainly include optical motion capture, curvature sensor motion capture, and IMU (Inertial Measurement Unit, inertial measurement unit) motion capture. Motion capture requires sensors and joints to achieve high-precision fit, and the degree of freedom of measurement is also limited. Therefore, IMU motion cap...
