Interior And Exterior Orientation In Photogrammetry

The interior orientation is the process whereby one can recover the digital image s coordinate system reference back to photogrammetric camera s metric coordinate system.

Interior and exterior orientation in photogrammetry. In interior orientation io the internal geometry of the camera or sensor is defined as it was during the time of photography. 5 4 exterior orientation. The parameters that describe this are the principal distance and the image coordinates of the principal point.

The determination of the attitude the position and the intrinsic geometric characteristics of the camera is recognised as the fundamental photogrammetric problem. Solutions for exterior orientation in pho togrammetry a review. This is possible through measuring the image s fiducial marks generally available in those taken with film cameras analog cameras.

That is it is the relationship between the ground and the image. Interior orientation establishes the relationship between the image plane and the projection center of a camera. 59 5 4 1 single photo resection.

In an ideal camera oft. It can be summarised as the determination of camera interior and exterior orientation parameters as well as the determination of 3d coordinates of object points. The exterior orientation aims to define the position and rotation of the camera at the instant of exposure.

During this process image pixel coordinate system is transformed to. For the interior orientation two sets of parameters have to be considered. Exterior orientation eo is the position and orientation of the camera when the image was taken.

Photogrammetry is an engineering discipline and as such heavily influenced by. The photogrammetric record an international journal of photogram metry 2002 17 100 pp 615 634. Photogrammetric resection is the problem of determining the interior and exterior orientation parameters of a camera based on known ground points x j y j z j and their corresponding photo plane.
