TO CONCLUSIVELY CHECK FOR HEAT WAVES, YOU CAN SIMPLY TAKE SEVERAL IMAGES OF THE SAME SCENE (NO
LOAD/MOTION) AND RUN THEM. IF HEAT WAVES ARE PRESENT, YOU WILL SEE LARGE DISPLACEMENT FIELDS THAT
CHANGE RANDOMLY FROM IMAGE TO IMAGE.
Once the camera positions have been set and the focus and aperture adjusted, calibration can begin. After this point,
changing any aspect of the camera system will invalidate the calibration; so, all adjustments should be carefully fixed at this
point.
• Tighten the tilt and rotation adjustments on the camera mounts.
• Lock the focus and aperture adjustments on the lenses, if possible.
• Tighten the tripod column.
• Tie the camera cables firmly to the tripod or crossbar; this will prevent external force on the cables from applying
leverage to the cameras.
