At first it sets up objective function on the basis of the deflectiondifference of the single working and updates the elastic modulus and geometric parameter of the model.
When the hue difference increased, the magnitude of color shift in test target decreased, but the deflection Angle of color shift vector from constant hue line increased.
A new means of determining astro geodetic deflection of the vertical CCD automatic astrometer and the new method to determine the difference of height anomalies between two points are described.
