Object Recognition for Interior Orientation in Digital Photogrammetry

چکیده
In this study, measuring processes of fiducial marks are performed with area based matching method. A computer program in Borland C++ Builder software is developed to find out the image fiducial marks particularly for this project. Ten images were taken by Wild RC 10 camera. They belonged to Selcuk University Campus area. The films were scanned by Zeiss Scai Photogrammetric Scanner (Pixel size is 21μ). Four fiducial marks on each image are automatically measured by area based matching method. Both residuals of fiducial marks on each image and root mean square error of transformation between pixel and image coordinate system are calculated. In addition, interior orientations of 10 images are manually achieved by Erdas Imagine Orthobase software. Residuals of fiducial marks and root mean square error of transformation between pixel and image coordinate system are manually calculated. Finally, both manual and automatic measurement techniques are compared with each other in terms of interior orientation accuracy.

A field investigation of application of digital terrestrial photogrammetry to characterize geometric properties of discontinuities in open-pit slopes
In order to analyze the slope stability in open-pit mines, the structural parameters of rock mass such as persistence and spatial orientation of discontinuities are characterized through field surveys, which involve spending high costs and times as well as posing high risks of rock toppling and rock fall. In the present work, a new application of terrestrial digital photogrammetry is introduced...

For many photogrammetric applications involving bundle adjustments, it is desirable to have a priori knowledge of the lens distortions, both radial and decentering. For close range applications involving focussing, other interior orientation parameters of principal distance and the location of the principal point may not be well known. A technique has been developed to determine the parameters ...

In this paper, an experiment system is developed to settle the problem about how to mapping a digital image onto 3D model from LIDAR data. Firstly, it chooses the corresponding points between point cloud and digital image, then, uses these corresponding points to calculate the exterior and interior orientation elements and systematic error corrections of image. For the purpose of improving the ...
