Hi Guys, A basic oxygen furnace is very large 400 ton vessel that steel is refined in. during the refining process oxygen is blown into the steel. during this process there is a flame at the mouth of the furnace, this is what im interesting in. during the process the flame changes in size and intensity. I want to be measure the intensity of the flame by using a camera to capture an image then use some c#/matlab code to calculate the intensity based on the RGB array of the image. will this work to give an indication of the relative intensity of the flames ? or have a missed the boat? can you clever people please help?
