The first prompt in the program will ask you for the name of the camera reference file to be created or modified. You may create a new camera reference file by entering a new name, or modify an existing camera reference file by entering the name of an existing camera file.
After entering the camera file name, following menu is displayed:
Please provide the following information
CAMERA NAME: camera name______
CAMERA IDENTIFICATION: identification___
CALIBRATED FOCAL LENGTH mm.:_________________
POINT OF SYMMETRY (X) mm.:_________________
POINT OF SYMMETRY (Y) mm.:_________________
MAXIMUM NUMBER OF FIDUCIALS:_________________
AFTER COMPLETING ALL ANSWERS, HIT <ESC> TO CONTINUE
(OR <Ctrl-C> TO CANCEL)
The camera name and identification describe the camera reference file.
The calibrated focal length and the point of symmetry are used in computing
the photo-to-target transformation parameters. These values should be entered
from the camera calibration report (usually available from the photograph
supplier). The maximum number of fiducials will determine the number
of fiducial or reasuae coordinate pairs to be entered below.
You are then ask to enter the X and Y photo coordinates of each fiducial as follows:
Please provide the following information
Fid# FID ID X Y
1__ _____ 0.0___ 0.0___
2__ _____ 0.0___ 0.0___
3__ _____ 0.0___ 0.0___
4__ _____ 0.0___ 0.0___
5__ _____ 0.0___ 0.0___
6__ _____ 0.0___ 0.0___
7__ _____ 0.0___ 0.0___
8__ _____ 0.0___ 0.0___
9__ _____ 0.0___ 0.0___
10_ _____ 0.0___ 0.0___
next: end__
AFTER COMPLETING ALL ANSWERS, HIT <ESC> TO CONTINUE
(OR <Ctrl-C> TO CANCEL)
The input display is repeated until the number of MAXIMUM FIDUCIALS
is reached. On this screen you should enter the fiducial or ressuae
photo-coordinates as given in the camera calibration report.
The X, and Y coordinates are in milli-meters from the principle point.
