Abstract：The block matrix is obtained by the detailed decomposition of vectormatrix that consists of exceptional conjugate points. The mathematical model of exceptional conjugate points detection is derived; the condition and minimum of exceptional points detection are given through the decomposed block matrix. The case study demonstrates that it is feasible to calculate the registration parameters after detecting and eliminating the exceptional conjugate points through this method, and it will be helpful to improve the accuracy of points cloud registration.
