| Abstract: | The correction of the nonuniformity of IRFPA is always done in engineering by using the one point and two point correction algorithms with poor accuracy,narrow dynamic range and high sensitivity with the nonlinear of IRFPA.In this paper two new multi point correction algorithms of the nonuniformity of IRFPA based on linear subsection interpolation and three order spline interpolation are put forward.These two algorithms can effectively overcome the shortcomings of one point and two point correction algorithms with some specialities such as high precision,broad dynamic range and be easy to realize in real time. |
