本文介绍了一种用于数字航拍图像的完全可操作的自动内部定向（AUTO-10），其基于用于基准标记粗定位的改进霍夫变换和用于精确测量的最小二乘匹配。对于具有基准标记识别符号的相机，例如 Leica RC30 相机中使用的相机，该程序能够确定照片的方向。结果是使用徕卡和蔡司相机拍摄的图像呈现的，这些图像在不同的扫描仪上以不同的分辨率进行扫描，以证明自动 I0 程序的潜力和稳健性。 AUTO-I0 在 Helava/Leica DPW770 数字摄影测量工作站上实施，并用于瑞士 swissair Photo+Surveys Ltd. 的数字制作环境。
A fully operational automatic interior orientation (AUTO- 10) for digital aerial images based on a modified Hough Transform for rough localization of fiducial marks and leastsquares matching for precise measurement is introduced in this paper. For cameras with fiducial mark identification symbols, e.g., as used in Leica RC30 cameras, the program is capable of determining the orientation of the photos. Results are presented using images taken by Leica and Zeiss cameras, which were scanned on different scanners in various resolutions to demonstrate the potential and robustness of the automatic I0 procedure. AUTO-I0 is implemented on a Helava/Leica DPW770 Digital Photogrammetric Workstation and is used in a digital production environment at swissair Photo+Surveys Ltd., Switzerland.
