Because this chart was optimized for self-illuminated endoscopes, which can have specular reflections (“hot spots”) near the center of the image, it has no critical features at the center of the chart.
It can be pre-distorted to work better with highly barrel-distorted cameras. It can be cropped, as long as the four registration marks are inside the image frame.
