Abstract
A new three-dimension deformation measurement method for large structure using strapdown inertial system is proposed, and the measurement principle is introduced. Making use of coordinate transition, attitude matrix solution and trail calculation, mathematics model and algorithms are availabe. Moreover, the corresponding error correction methods are presented to improve resolution of the measurement.
