滤光片对航摄仪内方位元素、畸变差的影响

EFFECT OF FILTERS ON INTERIOR ORIENTATION ELEMENTS AND DISTORTION OF AERIAL SURVEY CAMERA

本文论述了滤光片的不平整度和光谱透射特性对航摄仪内方位元素、畸变差的影响,并对航摄仪不戴滤光片与戴滤光片做了对照检定实验,理论分析及实验结果都表明:滤光片对内方位元素、畸变差有较大影响,尤其对色像差较大的航摄仪,其影响更大。文章建议,航摄仪在检定时应加戴航摄时使用的滤光片。

This paper discusses effect of smoothness and spectral transmittence of filters on interior orientation elements and distortion of aerial survey camera. Experiments of calibration are performed of aerial survey camera with and without filter. The study shows that a filter greatly changes interior orientation elements and distortion of aerial survey camera, experially those of chromatic aberration aerial survey camera. The author proposes that aerial survey camera should be calibrated with the same filter in photography.
