I have a set of grove IMU's connected together through a multiplexer currently outputting x,y, and z acceleration as well as roll, pitch, and yaw. The sensors are to be attached to a person then the person will move and their movement will be mimicked by a stick figure (Digital Twin) on a computer screen. I am struggling to figure out a method of translating the information to useful information. I assume it would be a double integration but how would I carry this out or are there any simpler methods?
I have a central sensor and can get the person to stand in a standard position for calibration. I understand the issues with inaccuracy but it just needs to be close enough to form the model nothing really accurate.
