During the process of collecting laser bath temperature data by CCD industrial camera, due to the influence of laser cladding process and installation location of mechanical equipment, the lens axis of CCD industrial camera is not perpendicular to the surface of the molten pool, resulting in positioning error caused by tilting photography. In order to eliminate the influence of positioning error and restore the true shape of the molten pool, a position calibration method for the temperature image of molten pool based on image processing technology was proposed. The experimental results show that after image processing the acquired image data of the molten pool was restored image morphology, which laid the foundation for subsequent image processing.
