Automatic Interior Orientation of Digital Aerial Images
نویسندگان
چکیده
A fully operational automatic interior orientation (AUTO_IO) for digital aerial images based on a modified Hough Transform for rough localization of fiducial marks and Least Squares 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 to determine 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 IO procedure. AUTO_IO is implemented on a Digital Photogrammetric Workstation Helava/Leica DPW770 and is used in a digital production environment at swissair Photo+Surveys Ltd., Switzerland.

Designing and Developing a Fully Automatic Interior Orientation Method in a Digital Photogrammetric Workstation
This paper is concerned with a comparative study and implementation of different image correlation techniques for Automatic Inner Orientation in aerial images. The implemented image correlation techniques are: Cross Correlation Function (CCF), Binary Cross Correlation Function (BCCF) and Least Square Matching (LSM). The first two approaches are used to determine the approximate position of the ...
متن کاملKohonen Self Organizing for Automatic Identification of Cartographic Objects
Automatic identification and localization of cartographic objects in aerial and satellite images have gained increasing attention in recent years in digital photogrammetry and remote sensing. Although the automatic extraction of man made objects in essence is still an unresolved issue, the man made objects can be extracted from aerial photos and satellite images. Recently, the high-resolution s...

By far, many stereo-matching techniques have been successfully proposed and applied in digital aerial photogrammetry. However, due to some problems such as large parallaxes, occlusions, geometric deformations, and repetitive patterns in convergent close range images, these methods may not be applicable to the same level of success as that of aerial imagery. In order to overcome these shortcomin...

For calibrating the camera, an accurate determination of the interior orientation parameters is needed. For more accurate results, the calibration images should be taken under conditions that are similar to the field samples. The aim of this work is the establishment of an efficient and accurate digital camera calibration method to be used in particular working conditions, as it can be found wi...
