The effect on the sensor installation location is analysed and corrected with innovation, and the precision of the pose estimation is improved accordingly.
Results show that the position precision of the pose measurement system can reach 0.1 mm, the precision of the pitch and yaw angles is less than 0.1° and that of the roll angle can be up to 0.3°.
