%X The cloud point registration is a peoblem of three dimensional-datum transformation with big rotation angle.As the fitting coordinates of sphere target's centers in the two sets of scanning coordinate systems are both influnenced by errors,we introduce constrained total least-squares(CTLS) method for cloud point registration.We established the errors-in-variables(EIV) model with the constraints and revised the observed vector and the coefficient matrix.The calculated example has proved that the more reasona...
