The invention relates to a triaxial electric field correction method based on an Euler formula. According to the method, an Euler formula rotation matrix is utilized to sequentially convert an underwater electric field measured by an underwater detection device into an electric field under a geographic northeast coordinate system and an underwater electric field under a target coordinate system. The underwater detection device comprises a posture adjustment fixing frame and a three-component underwater potential sensor arranged on the posture adjustment fixing frame. According to the triaxialelectric field correction method based on the Euler formula, the underwater detection device is formed by installing the posture adjustment fixing frame additionally on a sensor and the sensor is enabled to complete local or overall automatic alignment in the vertical direction, so that related operation in the coordinate transformation process is reduced, the transformation speed is increased while the result accuracy is improved; in addition, the posture adjustment fixing frame provides needed containing space and peripheral protection for the probe rod probe, so that the sealing isolationeffect of the box body is enhanced while the manufacturing size and the overall weight of the box body are reduced.

    本发明涉及一种基于欧拉公式的三轴电场修正方法。本方法利用利用欧拉公式旋转矩阵,将水下探测装置测得的水下电场依次转换为地理北东地坐标系下电场和目标坐标系下的水下电场。所述水下探测装置包括姿态调整固定架和设置在该姿态调整固定架上的三分量水下电位传感器。本基于欧拉公式的三轴电场修正方法,通过在传感器上增设姿态调整固定架构成的水下探测装置,使传感器在竖直方向完成局部或整体的自动找正,进而减少坐标转化过程中的相关运算,在提高结果准确性的基础上,提高了转换速度,另外姿态调整固定架为探杆探头提供了所需的容置空间和外围保护,在缩小箱体制造体积和整体重量的基础上,还增强了箱体的密封隔离效果。
