Digital Image Processing of CCD Measuring Temperature Field in Coaxial Powder Stream of Laser Cladding
In this paper, the theory of the powder temperature measurement using radiation is briefly illustrated, and the measurement system on temperature field in coaxial powder stream of laser cladding by applying color CCD and digital image processing technology is designed. The experimental result indicates that this measurement system can test the distribution of temperature field.
