Paper Abstract

In this paper, according to the relation of light source, RGB tricolor and color temperature, considering the rule of constant brightness, firstly, the color pictures of laser welding plasma were input into computer in the term of COLOR RGB through AGFA SCANNER, then grading grey scale properly to each picture element's three primary color, so the constant value lines of three primary color and the constant value line of the color picture brightness can be determined. Apparently, each constant value line of brightness corresponds a isothermal line and the denser the constant value lines are, the larger the gradient of temperature change is.
