摘要
针对在进行卫星影像纠正时侧视角对纠正精度的影响,阐述了这种影响产生的原因和影响的程度,同时从原理上论证了侧视角与高程精度的关系,以及对纠正精度的影响程度,并且通过实验证明了此结论的有效性。运用此分析方法,可在生产中有效地规划资源和合理地评价成果质量。
The correcting precision may be affected by the incidence angle during correction of satellite images.This article clarifies the reason why this influence occur and the extent it may achieve.Meanwhile,we make a fundamental proof of the connection between the incidence angle and the height precision,as well as the extent that the incidence angle may affect the correcting precision.Moreover,through an experimental approach,the vality of our conclusion was confirmed.It is supposed that,with this analysing method used in manufacture,resources can be arranged properly,and reasonable judgement can be made for quality of the products.
