基于普通数码相机的近景摄影测量方法与精度的试验研究

Research on the Close-range Photogrammetry Experiment based on General Digital Camera

普通数码相机由于体积小、重量轻、价格低廉、像素几何位置精度高、影像可直接输入计算机进行处理等优点备受人们青睐。随着数字摄影测量技术的发展,数码相机分辨率的不断提高,人们开始考虑能否将普通数码相机应用于工程实践。本文以普通数码相机作为影像信息的获取手段,就控制点的数量、分布、精度、影像获取及其量测方法、数据处理解算方法、解算精度等问题进行了研究。

The digital camera has lots of advantages,such as small size,light weight,inexpesive,high precision of pixel position,and available to be imported into computers etc, so it becomes more and more popular. With the development of digital photogrammetry and the increase of resolution of digital cameras, the feasibility of putting general camera to engineering use is considered. Based on images by general digital camera,the number, distribution and presicion of control points, the digital image acquirement and ...
