摘要

In order to satisfy the positioning accuracy identification requirement of MUAV navigation system, the characteristics of visual navigation were analyzed, the existing navigation system accuracy assessment methods were summarized and the conversion relationship of each index were deduced. According to the Ethridge statistical algorithm for calculating circular error probability (CEP), navigation and positioning accuracy assessment scheme were designed. Finally, the time-CEP (TCEP) accuracy evaluation method based on visual measurement was put forward, which were verified by simulation using four group actual INS' data. The results show that: the scheme is feasible, convenient and practical; the method can relatively comprehensive evaluate the positioning accuracy of navigation system and can make full use of the single trial data.
