Multi-vector Matching Deformation Measurement Method

This paper introduces a novel multi-vector matching deformation measurement method designed to enhance the stability of deformation measurements in static environments by incorporating specific force observations. The approach effectively measures shift deformation and extends the deformation measurement range by integrating with the velocity matching equation. Furthermore, we propose a conversion model that addresses angular deformation and shift deformation, offering a solution for measuring shift deformation in environments where comparison force observations may not be straightforward. Real inertial navigation experiments conducted in a laboratory setting demonstrate the method’s capability to measure deformation in static environments while simultaneously capturing shift deformation. The results illustrate the method’s effectiveness in practical deformation measurement scenarios.
