The equi-density slicing of an aero-photograph by a laser scanner is reported. The laser scanner provides a scanning beam with a spatial resolution of 40 μ and a scanning area of 40 × 40 mm~2. The density of the aero-photograph scanned is detected by a photomultiplier with 8-10 bit grey level and 10~4-10~5 dynamic range.

本文介绍了用光学扫描方法对拍摄的航空照片进行了等密度测试。本方法中,激光扫描系统提供了空间分辨率为40μ的扫描光束,扫描范围40×40mm~2。测量的底片密度灰级可达8—10bit,利用光电倍增管接受光信号,底片密度的动态测量范围可扩展到4~5个量级。

In order to establish a quantitative relationship between the gray scale density of films in model DGP-ⅡA multispectral band camera and the radiance of terrain subjects imaged on the film, we fabricated and calibrated a group of simple radiance-meters corresponding to the 4-spectral bands of the camera. When taking the photographs of the standard ground subjects, we at the same time measured their radiations for each band by means of the radiance-meters, then calculated the radiance of the ground subjects corresponding...

In order to establish a quantitative relationship between the gray scale density of films in model DGP-ⅡA multispectral band camera and the radiance of terrain subjects imaged on the film, we fabricated and calibrated a group of simple radiance-meters corresponding to the 4-spectral bands of the camera. When taking the photographs of the standard ground subjects, we at the same time measured their radiations for each band by means of the radiance-meters, then calculated the radiance of the ground subjects corresponding to the film density and calibrated the gray scale of the films with considerations of the spectral response of the films and the transmittance of the filters.

为了在DGP—ⅡA型多光谱相机4个波段底片灰标的密度和所拍摄的地物辐亮度之间建立定量关系,自制并标定了相应于该相机4个波段的简易辐亮度计,用相机拍摄地标的同时,用辐亮度计测量地标的各波段辐亮度,在考虑底片光谱响应和滤光片透过率的情况下,算出了与底片密度对应的地标的辐亮度,因而标定了底片的灰标。
