The boundary element method is a sort of simple and applicable numerical method for the magnetic field data conversion from curved-surface to horizontal-plane. The method needs, however, to estimation a huge and high order equation, and the boundary value error is also great. The wavelet compression algorithm is applied to reduce the order and compress the equation to improve the efficiency and enhance the computer’ playing, and achieve 45% compress ratio with an assuring adequacy precision. The numerical results of a model calculation verify the flexibility of the method for the magnetic field data conversion from curved-surface into horizontal-plane.
