Focus on the problem that noise is existing in the input signals and output signals of visual measurement system, if calculate via the classic least mean square algorithm or recursive least square, it would generate the larger errors; Or calculate directly, the calculation work loading is too complex . So the solution of weight vector could be as the limited best optimization solution of Rayleigh Quotient of augmentation input vector self correlation matrix, take iteration estimation to the augmentation input vector and set up the function relationship between step factor and error; The simulation analysis experiment results indicate the standard tolerance of proposed adaptive total least squares algorithm is 0.0375mm; but the one of normal total least squares algorithm is only 0.0598mm . Obviously, the proposed algorithm has more high precision than normal total least squares algorithm, and its structure is simple, the calculation speed is faster .
