The Software Development of Double-Beam Centroid Distance Measurement System in Laser Cladding Forming Process
In the high-piled up process of laser cladding rapid forming , the distance between aser molten pool center and flour will increase along with the cladding layer ,which will cause the effect of light powder coupling getting worse, even directly lead to failure. The article proposed characteristics of the double-spot ,formed by molten pool and reflection of laser surface;used VC++ 6.0 as the development platform of image processing to calculate two spot centroid distance by dealing two spot image with the process of gray processing, Gaussian smoothing, binary threshold segmentation, area centroid calculation, the centroid coordinate distance calculation.At the same time , controlling laser head Z to move in accordance with the value increment,to increase the stability of forming process and forming quality.
