Publication of the results of each contributor resulting from
the working group activities commenced in August 1977 [3, 4, 5] with
an editorial giving some background information.
This report reviews results published or submitted for publicat- |
ion up to March 1978, and results of a comparison carried out at The |
Ohio State University in Columbus, Ohio, U.S.A.
The two cameras used throughout the project were a Wild RC8
camera with the Universal-Aviogon-5.6/153 lens cone no. 15 UAg R-10
| and a Zeiss RMK camera with the Pleogon-AR-5.6/153 lens cone no. |
| 98222. Both lenses were manufactured in 1967 and are equipped with da
a front-projected reseau. The reseau points are marked on the iast |
glass surface - a plane surface - of the lens close to and facing the
image plane. The crosses representing the reseau points are
projected as shadow images. *
2. IMAGE QUALITY
Image quality evaluations were included into the working group
I Program in recognition of a certain correlation between image
| geometry and image quality.
Photogrammetrists still primarily use resolving power as a
| criterion for image quality. It is therefore appropriate to present
here first the resolving power data obtained for the two cameras
by working group members. Figures 1 and 2 portraying the resolving
| power of the two lenses by a continuous and a dashed line for radial
and tangential bars respectively, were presented by Hakkarainen [4].
They have been extended by data provided by Hakkarainen [4], Qe
Gliatti [7] and Tayman [12].
Tayman determined the resolving power by exposure of bar-targets
with a maximum resolution of 113 1/mm on plates coated with Kodak
Spectroscopic V-F Panchromatic emulsion and on Kodak 2405 film
coated with Kodak Double-X emulsion. The results from the plates are
indicated by the capital letters R and T, those from the film by the
letters r and t.
Gliatti determined resoiution from Edge Gradient, Moduiation |
Transform analysis of negatives taken with the two cameras |
simultaneously at the scale of 1:26000 on kodak 2405 film coated
with Double-X emulsion. The photographs were not obtained especially
