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.
