Inertial Measurement Units (IMUs) in Drowning Prevention: An Exploratory Study

International Journal of Aquatic Research and Education, 2015
The use of inertial measurement unit (IMUs) sensors in competitive swimming movement analysis has become increasingly popular but has not been applied to measuring water competencies related to drowning prevention. This study explored the potential use of IMU sensors in three simulated water competency activities in a pool environment.

Positioning and navigation of mobile robot with asynchronous fusion of binocular vision system and inertial navigation system

International Journal of Advanced Robotic Systems, 2017
Binocular stereovision–based positioning and inertial measurement–based positioning have their respective limitations. Asynchronous fusion of a binocular vision system and an inertial navigation system (INS) is therefore introduced to global positioning ...
