This chart is designed for testing automative cameras or other significantly distorted cameras. This large chart is designed to be reflectively lit, and captured at a an optimal focus distance.

Options include:

  • Pre-distortion: Most automotive camera modules have significant fisheye distortion which can make it difficult to the outside of the image field. this chart has pincussion pre-distortion to approximately compensate for the barrel distiortion of the automotive camera module. The distortion coefficients that should be entered into the Imatest SFRplus settings window are [1.167 1.577]
  • Square Grid: 5x7 slanted square grid 
  • Substrate & ink type: Matte paper & ink can be used to reduce reflected light. This is critical for high levels of distiortion, otherwise specular reflections can ruin MTF measurements
  • Contrast levels: 10:1 contrast ratio, common for several automative testing standards
  • Color chart: a 20 patch color chart for color accuracy and bayer filter position verification
  • Bar to Bar height:  the maximum bar to bar height is 38.5 inches on the left and right side.  The minimum bar to bar height is 23.5 inches in the center.
  • Active Area: the extra-large chart be used for sensor sizes above 24 MP. This chart has an active area of 1500mm x 965mm and is printed on 1117 mm X 1524 mm inch paper

The active area of the chart includes white space above and below the top and bottom distortion bars. It is slightly larger than the printed area, which is bounded by the distortion bars on top and bottom. White space is included in active area because test images of the chart must include this white space in order to enable automated processing in SFRplus software.

FAQs About  SFRPlus Test Charts

A colorimeter is a quick and inexpensive method to measure color and to control color in a material or solution. It is used to maintain color consistency during production and to check the chemical concentration. It also assists with the quality control of labs, food, textiles, and pharmaceuticals.


A spectrophotometer measures the full visible color spectrum (typically 400–700 nm). It offers significantly higher precision and enables detailed evaluations – including spectral curves, ΔE values, and color distance measurements. It is the preferred choice for demanding applications in labs or color development environments. learn more..

The core difference between a colorimeter and a spectrophotometer lies in their light measurement methods. A colorimeter measures color values based on the tristimulus method (e.g. LAB or RGB) and compares the sample to a reference. It's ideal for quick, repeatable measurements under consistent conditions – such as in production or incoming goods control.

A paint gloss meter is used to measure the level of paint gloss, whereby it reflects light at some angles, such as 20°, 60°, or 85° angles, and measures the intensity of that light. To measure surface sheen, the level of gloss is compared to standards that are calibrated and reported in units of gloss (GU).


There are many factors that can influence accuracy such as surface roughness, temperature, substrate material, and calibration settings. For ferrous metals, external magnetic fields can also distort measurements. Proper calibration and preparation will help reduce the impact of these factors.


Depending on the scale of the manufacturer, its matte, low-sheen finish can be called gloss level 3. Overall, gloss levels in certain standards go between 1 (flat) to 7 (high gloss). Level 3 is considered low-gloss or satin-like.


D/8°and 45°/0°are two kinds of illumination geometry with different optical geometry design. D/8°illumination geometry is more widely used for the color comparison and measurement of high-gloss materials; 45°/0°illumination geometry is mainly used in printing and packaging industries.
