Two-camera problems

• Inconsistent CCD placement
• Baseline error
• Matched focal points

Calibration fixes

• Find center pixel through spherical distortion calibration
• Dewarp image from calculated center pixel
• Account for potential baseline and focal point error in sensitivity calculation

Show sensitivity for baseline error.

Talk about CCD inaccuracies (sensitivities of geometry itself)

Inconsistent CCD placement if not accounted for can vary the angle depending on the error of the image. (spherical distortion example)
