4.5 Perform Initial Lens Adjustment and Camera Aiming
1. Back away all of the thumbscrews on the lens holder until they do not touch the knurled adjustment rings on
the lens.
2. Loosen the roll, pan, and tilt bolts on the JAI camera mounting head until each axis can be easily adjusted by
hand but any particular setting will stay in place after you let go.
3. Power on the setup computer and then start the ENSetup program. Press the “Video Window” button to open
the Video Window and then select the camera for adjustment from the tree-view on the left side of the
window. Press the “Live” button in the toolbar to start the video streaming. Press the “Tilt Line” button to
show the alignment guidelines.
The “Tilt Line” can be moved using the mouse, or if the “Tilt Line” is selected, using the arrow-keys. Keep in mind
the image in the video window by default is the center of the camera field of view. You may have to scroll the
image up or down to place the Tilt Line tool where you want the vehicle plate to be in the image.
4. Open EN Setup Video Window Settings. Configure Plate Width to the targeted number of pixels per plate. A
typical value is 135 – 150 pixels which provides high ALPR performance.
5. Interactively adjust the roll, pan, and tilt of the camera mount and the lens zoom and focus rings:
5.1 Adjust the lens focus ring (and camera pan and tilt as necessary) to obtain a focused image of the plate.
5.2 Adjust the lens zoom ring to obtain a plate width approximately equal to the distance between the short
vertical sizing marks that appear above the tilt line. Scroll the image horizontally to check edge to edge
coverage of the field of view as desired.
6. Repeat step 5 iteratively until no further adjustments are needed between each steps.
Note: For viewing full image right click in Video Window and select Preview Image. The adjustments still have
to be done from Video Window but the Preview shows how the full image looks.
