Abstract:A method for largerotationangle three dimensional rectangular coordinate transformation based on nonlinearleastsquares algorithm is put forward,which can achive the best valuation of sevenparameter by solving multifunction minimum. This method has many advantages, such as calculating simply, converging rapidly, relying less on the initial values of 7 transformational parameters, facilitating program realization. A simulation example and the comparison with other method prove its validity finally.
