摘　　要：水下磁传感器位置偏差直接影响磁场测量的精度,针对复杂水下环境下阵列铺设磁传感器的定位问题,文章提出了基于Hough变换的磁传感器定位方法。首先,在标准矩形线圈磁场源下得到阵列磁传感器的测量值,根据磁场强度公式计算每个磁传感器的位置;其次,采用Hough变换,将每个磁传感器位置从笛卡尔坐标转换到极坐标,利用能量积累判断位置偏离较大的磁传感器。仿真结果表明,该方法能够有效降低磁传感器定位偏差。The position deviation of underwater magnetic sensor directly affects the precision of magnetic field measurement.Aiming at the positioning problem of array laying magnetic sensor in complex underwater environment,this paper presents a magnetic sensor location method based on Hough transform.Firstly,the measured values of the array magnetic sensors are obtained under a standard rectangular coil magnetic field source,and the position of each magnetic sensor can be calculated according to the magnetic field strength formulas.Then,Hough transform is used to convert the position of each magnetic sensor from Cartesian coordinates to polar coordinates,and the magnetic sensor with large position deviation is judged by energy accumulation.The simulation results show that this method can effectively reduce the positioning deviation of the magnetic sensors.
