1. In the IMS control panel select Motion and then Drive Disable from the dropdown menu (Figure 7). You will have to move the camera by hand for the calibration, disabling the motor allows manual movement of the camera on the track.
...
2. Open JAI Camera Setup utility: In the IMS control panel click Instruments > JAI Camera Settings (Figure 8). The lights turn on automatically when the JAI Camera Setup window opens.
...
...
1. Click the Gains-Black-Shade-Flat tab (Figure 14).
Figure 14. JAI Camera Setup Window showing the Gains-Black-Shade-Flat tab. The Gains-Black-Shade-Flat tab is outlined in red.
...
2. Click the Clear All Gains, Clear Black Gains, Remove Pixel Black Correction, Remove Shading Correction, and Remove Pixel Gain Correction (Figure 15). You will notice all values in the Master and Black gains go to zero.
Figure 15. Remove the corrections and clear gains.
3. Check the camera's f/stop which should either f/16 or f/22 (see Figure 16). Remember that the higher the f-stop the greater the depth of focus. The down side is that a higher f-stops means less light and low light levels mean longer exposures - which means slow track speeds for scanning - which could impact core flow in the lab. So on a low recovery expedition you can afford the longer scan time, so go for f/22 otherwise f/16. If you are doing 360-imaging f/22 is a must. Check with the LO and EPM if you are unsure of the time needed for scanning sections.
...
5. Adjust the Master Black value unit the Green value is near 15. 40 is a good starting value for and we increasing to 60 works best.
6. Adjust the Red Black and Blue Black Gains until the ratio are close to 1.000 +/- 0.05. The RGB values of the Black square is balanced (R=50, G=50, B=50) so achieving a ratio of 1.000 is best.

Image striking is caused when used a non-uniform standard for the Pixel Gain Correction correction or just from dirt. Until we found the silicone sheets we would have to defocus the lens to mitigate this issues. If see streaks chack your target material and repeat this correction. |
Pixel Black Auto Correction
1. The new light set up makes adding a lens cap difficult so it has been decided and tested that the pixel black auto correction can be done without the cap. But Ensure the lights are off.
...
Figure 24. Pixel Black Correction applied.
Shading Correction
- Take the heat resistant gray silicone mat and wooden board from the SHIL calibration drawer. Clean off any dust with a piece of tape (Figure 25). Dust will cause unwanted artifacts in the image. The mat must be clean and flat on the track.
- Place the heat resistant gray silicone mat on the track. Make sure that it is level and perpendicular to the camera’s axis.
- Click Lights On, and move the camera over the gray mat.
- Note for Tech: previously we defocused the lens to preform the Shading correction. That is no longer needed because the silicone mat is even in color/texture.
Figure 25. The Gray silicone mat being cleaned with tape.
5. The RGB lines should first appear “bowed” evenly across profile and centered in the image (Figure 26). If not check the orientation of the gray mat, it needs to be flat and perpendicular to the camera. This very important. A wooden holder was designed to hold the mat, it should be in the SHIL calibration drawer.
Figure 26. Grayscale card corresponding RGB Profile visible.
6. Click the Shading Correction - Flat Method button. This can take a few seconds, don’t click anything else until it is done. The RGB lines should now be flat (Figure 27).
Figure 27. Image grab and profile after the Shading Correction has been applied.
Pixel Gain Correction
1. Make sure gray silicone mat is flat.
2. Click Lights ON
3. Click the Pixel Gain Correction - Flat Method button and move the camera slowly back and forth. This averages the pixels and helps eliminate streaking in the image. This will take several seconds, don’t click anything else until it is done. When its done the RGB lines should still be flat and the individual RGB the same, but may not be equal to each other.
IMAGE Calibration (Correction)
...
1. Place the 3D calibration standard on track as shown (Figure 28). Be sure to use the XRite Color checker 2019. The color squares must be oriented as pictured below, butted against the red reflection bar.
Figure 28. Color standard in track in correct orientation.
...
2. Adjust the Brightness, Contrast, and Gamma levels (Figure 35-1) to achieve a straight line in the Applied Corrections tab and the RGB Corrected values in the Compare tab should have values near 242 for the white square and near 50 for the black. We want a linear relationship between the measured and given values. Each BCG setting adjusts the line in different ways and there are many different ways to adjust the values to achieve a linear relationship. You want to achieve a good image with good brightness, where the image has good saturation and not too washed out. The Applied Corrections Graph should be a straight line and the ROI Corrected box for the color selected (Figure 35-2, 35-3) should have values near the RGB values of the Color Checker STND. These may change depending on the instance of extreme colors, extremely white or extremely dark cores, in which the settings may have be tweaked more to get a user friendly consumer image.
...
1. To double check your calibration under the same scanning conditions as the scientists see, scan an image of the 3D standard without the color checker box selected.
2. Click Crop and Click Save

C.3 VCD-S Configuration
"Scratch sheets" are printouts of section half images produced by SHIL. The sheet is a LabVIEW VI with embedded images that can print automatically when a user 'saves' an image. The VI is scaled to print SHIL images correctly on 11x17" paper in portrait orientation. The scratch sheet can be customized to include various columns to capture descriptions or drawings on paper. The goal of this guide is to instruct how to use and customize scratch sheets.

All improvements to the Quick Start Guides and User Guides are a communal effort, with honorable mention to the group of LOs, ALOs, and technicians who have helped.
VII. LIMS Component Tables
The following LIMS component tables are included under the Section Half Imaging Logger (SHIL):
- LSIMG - linescan imaging of the section half
- WRLS - linescan imaging of the individual 90-degree quadrants for whole-round imaging of the outside of a hard rock section
- WRLSC - component for the collection of the final 90-degree quadrant images as well as the 360-degree composite image
