I need to measure the width of a bar made out of glowing red steel (900-1200 degrees Celsius) using computer vision.
In order to ensure resolution of a 0.5 millimeters/px, the camera is needed to have enough pixels and, considering the field-of-view, to be at a certain distance from the bar.
Can anybody think of a way to use a camera at a distance of 0.5m from the glowing hot bar? Air refrigeration? Refractory enclosure?
Let's talk about it?
