Visualization interface for posture monitoring of wheel loaders based on inertial sensors

Wheel loaders need an interactive interface to collect and display the posture information when they operate in a harsh environment. This paper proposes a visualization interface for posture monitoring of wheel loaders. It is driven by the data from the inertial measurement system based on attitude heading reference system, including a real-time three-dimensional animation display system created using OpenGL. The proposed system could be effectively used for monitoring the body posture of wheel loaders under the influence of the external environment. Experimental results are presented to show the good accuracy and real-time performance of the proposed monitoring system. Moreover, the proposed system could enhance vehicle safety, remote operability, and human–vehicle interaction.
