Options include:
Predistortion: Most car camera modules have significant fisheye distortion, which can make it difficult to perform outside of the image field. The graph has a vibration predistortion to approximately compensate for the barrel distortion of the automotive camera module. The distortion factor that should be entered into the Imatest SFRplus Settings window is [1.167 1.577]
Square grid: 5x7 square grid
Substrate and Ink Type: Matte paper and ink can be used to reduce the reflected light. This is crucial for high levels of distortion, or specular reflection can disrupt MTF measurements
Contrast: Contrast ratio of 10: 1, usually used for several automatic test standards
Color Chart: 20-color chart for color accuracy and Bayer filter position verification
Bar to Bar Height: The bar's top bar height is 38.5 inches left and right. The bar's minimum bar height is 23.5 inches in the center.
Active Area: Very large chart for sensors above 24MP. The chart has an effective area of 1500 mm x 965 mm printed on 1117 mm x 1524 mm paper
The active area of the chart includes white space above and below the top and bottom bar. It is slightly larger than the print area, defined by the upper and lower deformation bars. The blank area is included in the active area because the chart's test image must contain this blank area to be processed automatically in the SFRplus software.
