摘要
非量测相机广泛应用于摄影测量领域,因此必须对其成像性能进行测定。本文分析了影响调制传递函数的因素,设计了利用影像的灰度曲线测定非量测相机成像性能的方法,经过与调制传递函数曲线的对比实验,表明了该方法具有简单、便于操作、稳定可靠的特点。
Due to the non-measurable digital camera is applied extensively in photogrammetry,it is necessary to determine the imaging capability of the non-measurable digital camera;the paper analyses the factors influencing MTF,and designs a method using grey level curves of the images to assess the imaging capability of the non-measurable digital cameras,the result,compared with MTF,indicates that,this method is simple,convenient and credible.
