| Abstract: | This paper briefly introduces the experiment of Inter- Calibration of HJ - 1 satellite CCD camera, and analyses math theory of three algorithms, including normalized coefficients algorithm, two - point algorithm and least square. Then the coefficients are extracted through the piecewise normalized coefficients algorithm,piecewise two - point algorithm and piecewise least square, and the error analysis are also appraised. |
