基于红外被动测距的基线拟合算法研究
Study on baseline fitting method based on passive infrared range measurement
摘要
Abstract
In order to measure the range accurately and calculate the transmittance precisely with infrared spectrum passive ranging technology,baseline was fitted with interpolation method. Taking oxygen A band as an example, baseline fitting was completed through a variety of interpolation fitting methods making use of both sides of the absorption data from line-by-line radiative transfer model. Meanwhile, detail theoretical analysis and simulation verification were carried out, after comparing several algorithms, the accuracy of polynomial interpolation fitting is the best. The implementation of baseline fitting algorithm provides method for establishing a database of transmittance, distance and other conditions and provides a solid foundation for realization of passive ranging.关键词
