摘要

Trajectory accuracy assessment requires calculating the transformational alignment between the reference system and the measured positioning system. This paper conducts a detailed analysis of this scenario and establishes a standardized problem model. A reliable solution method is proposed for this problem model. In comparison to existing algorithms, the algorithm presented in this paper demonstrates a more comprehensive and targeted approach to handling data within positioning trajectories. Experimental validation confirms the feasibility and reliability of the proposed method.
