Distortion Note: High amounts of distortion where the target may be compressed so that the major axis is 50% larger than the minor axis may have issues with autodetection. Pre-distortion for may be necessary for these cases.
Detail information
SFRreg targets can be placed at arbitrary positions and angles to accommodate a wide variety of test cases:
- Long distance tests where conventional charts would be impractically large
- Ultra-wide Field of View tests (>170) where a flat target cannot reach the outer field
- Autofocus tests where a single frame can contain several targets placed at different distances
