Real Time Correction of Atmospheric Refractive Error Based on NURBS Curve Interpolation
基于NURBS曲线插值的实时大气折射误差修正

A technology,which integrated the traditional algorithm of tracing by every vertex with NURBS curve interpolation method,was put forward. This technology was applied in high precision and real time correction of atmospheric refractive error field of many visible light measure equipments. Some shortcomings such as large quantity calculation, nonreal time calculate of algorithm of tracing by every vertex could be overcome by this method. The method was particularly fit for correcting the atmospheric refractive error in the real time data interpretation of full-automatic film interpretoscopes or optic-electronic theodolite.
