to the ground, eliminating possible time correlation', errors. The
technical procedures to be used are described in Appendix B. They have
been performed within the present "A" program.
3. Determination of exterior orientation of each nancaramic frame.
By correlating the panoramic imagery around the principal point (image
coordinates x=0; ; -fd -- 0 where f=focal length and d'" sweep angle) with
the corresponding terrain imagery shown on the 70mm 70mm frames, the
pitch, roll. and yaw of the principal camera axis will be determined with
respect to a defined coordinate system. In addition to the exterior
orientation, the resultant data will show timing discrepancies between the
shutter of the ground frame camera and the zero passe of the panoramic
camera. It will also show the exact relative orientation of the two
panoramic cameras as well as possible changes in it dring the mission.
The procedures to be used for the determination of pi. Ich roll and yaw
are currently being used, although for a different purpose, in the evaluation
of "A" photography.
