摘　　要：为提高无线基站勘察效率,给出了一种改进的图像拼接方法,并将其应用到无线基站勘察中进行验证。首先提取无线基站勘察图像的SIFT特征点,然后计算其64维向量描述子;采用最近邻与次近邻之比进行双向匹配,消除匹配错误;采用加权平均融合法进行图像融合,最后将此方法结合无线基站勘察进行实际应用。实验结果证明,本文方法能够精准快速进行勘察图像拼接,有较好鲁棒性,能够明显提高了勘察人员的工作效率,具有一定的实际应用价值。According to the tactical use of self-propelled acoustic decoy and submarine characteristics, the location method of self-propelled acoustic decoy based on short baseline array is discussed, and the short baseline array system＇s function and array are designed. The Short baseline array＇ s position calculating method is also studied, and analysed direction-finding error distribution of typical working conditions. The simulation results show that di- rection-finding precision of the system is better than 1 degree within 5 km range , that can satisfy the countermeasure efficiency assessment requirements of the self-propelled acoustic decoy.
