Overview of Parallel Platform Attitude Measuring Methods

To solve the parallel platform attitude measurement problems of low accuracy and low efficiency, the existing measurement methods will be summarized in this paper. The existing methods are mainly divided into the drive rod method, the optical sensor method and the accelerometer measurement method. In this paper, three optical sensor methods are introduced, namely the CCD camera method, the PSD sensor method and the laser interferometry technique method. Moreover, the parallel platform attitude measuring steps based on accelerometers are proposed. Finally, on account of comparison, prospect of the development of measuring methods is given.
