Figure 15.5c Calibration Images
Note: After the first four images with the diagonal stripe pattern are captured, you can
leave the system unattended while the program continues to completion. Some
of the following images appear stretched in one dimension; however, this is
normal.
9. Go to the Capture directory where all Capture Calibration files are saved.
10. Select Offline > File > Browse or click on Browse to review all Capture Calibration files.
11. Verify that all calibration images contain features spanning the full width and height of the
image frame (see the right image in Figure 15.5c).
12. Recapture all images unsuitable for calibration. Record the file name extensions for all
unusable files (e.g., .cxy, .dyy), then delete the files.
13. Re-engage on the reference surface and select Capture Calibration.
14. Verify that the file name prefix is identical to that of the usable files. Remove the “x” from all
file name extensions (except for the unusable file names recorded in Step 12).
15. Finally, click on Capture to recapture the selected files.
