WebOct 2, 2024 · In its deployment environment, the In-Sight vision system may capture images that exhibit distortions induced by certain setup conditions, such as lens and perspective distortions. Some lens may produce barrel or pincushion radial distortion patterns which cause lines which appear straight in the real-world to appear as curved lines in the image.
