多年来,摄影测量在地质填图中起着重要作用,但是把摄影测量和计算机结合起来,能够自动地进行地质测图还是近几年来的事。现在,美国地质调查所设在丹佛的地质摄影绘图实验室和丹麦设在哥本哈根的格陵兰地质调查处分别研制了一种用于地质研究的自动摄影测图系统,这种摄影测图系统借助计算机不仅可以对航空照片和宇航图象进行地质解译,而且还可以直接根据航空照片和宇航图象自动编绘地质图、剖面图、构造等高线图和等值线图。 1。计算机辅助的摄影测图系统的基本组件任何一种计算机化的摄影测图系统的基本组件都应包括:三轴(x y z)编码器、摄影绘图议的跟迹滑架、硬件接口和计算机。计算机的作用是把模型座标值转换成由编码器
For many years, photogrammetry has played an important role in geological mapping, but the combination of photogrammetry and computing can make geophysical mapping automatically in recent years. Now, the Geological Survey of the United States Geological Survey in Denver’s Geological Photogrammetry Laboratory and the Danish-based Greenland Geological Survey in Copenhagen have developed an automatic photogrammetry system for geological research that uses photogrammetry systems not only by computers You can geo-interpret aeronautical photographs and aerospace images, and you can also automatically map geological maps, profiles, contour maps, and contour maps directly from aerial photographs and aerospace images. 1. The basic components of a computer-aided photogrammetry system The basic components of any computerized photogrammetric system should include a three-axis (xyz) encoder, a photogrammitter tracking carriage, a hardware interface, and a computer. The role of the computer is to convert the model coordinate values to encoders
