The paper describes the Digitalization for aerophotography negative with different Scanning apertures, and the test about using these reproduced hardcopy images and it analyses the decreasing factor on the reproduced film image resolution.
本文通过不同扫描孔径对航摄底片进行数字化并回放成硬拷贝影像的试验,分析了回放片影像分辨率下降的原因,并提出,要使回放片的影像质量满足航测成图精度的要求,应采用高分辩率的航空胶片进行摄影,以便得到高质量的原始片,或采用更小的扫描孔径进行数字化,在回放时使用高分辩率的胶片,以使影像质量少受损失。
