| Abstract: | Based on the inertial measurement platform, the equal-space sampling method was used to acquire the measuring information from inertial measurement unit （IMU）, and empirical mode decomposition（EMD） method was conducted to eliminate the interference signal component. The digital integrator was designed for integrating the calculated inertia information, and the relative spatial trajectories was odtained. Experimental result shows that the accuracy of track triaxis absolute displacement measured by the described method is more than 97.17% . |
