Magnetic charge model for V-shaped crack and measurement equation are established. The optimization method of search approximation in the conjugate direction on quantitative analysis for crack is adopted. The problem in quantitative analysis for leakage magnetic field is solved. Testing result indicates that this algorithm converges rapidly to real solutions. The algorithm is an effective non-distructive testing method to realize quantitative testing for crack.
