提出了一种采用传统的逐点描迹法和NURBS曲线插值方法相结合的技术,对多种可见光测量设备进行高准确度的实时大气折射误差修正方法.该方法克服了逐点描迹法计算量大、无法达到实时计算要求等缺点,尤其适用于全自动胶片判读仪或光电经纬仪中实时数据的大气折射误差修正.

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.
