摘　　要：基于超声波测距,采用平面扫描方法获取超声波探头与定位目标的平面几何关系,从而推导出一种新型的X-Y二维全平面目标定位算法,对算法用良态矩阵理论分析定位误差的稳定性,推导出该算法产生较小误差时需满足的条件,并通过实验进行验证算法的可行性和稳定性。Based on ultrasonic ranging,plane scanning method is used to obtain the plane geometric relationship between ultrasonic probe and positioning target,and a new X-Y two-dimensional full plane target positioning algorithm is derived.The stability of positioning error is analyzed by good state matrix theory,and the conditions that the algorithm needs to meet when producing small error are deduced.The algorithm is verified by experiments Mobility and stability.
