| Abstract: | In order to monitor the GMAW droplet transfer form and droplet size,a high-speed camera system for droplet transfer is established,and the backlight source selection,optical design and image pickup device debugging are described,etc.Based on the droplet transfer video screenshot image,using CANNY image processing algorithm,combined with local attribute function,the edge contour of droplet is extracted through MATLAB software programming,and the droplet profile feature value is marked,and then the accurate droplet size characteristics information is obtained.This conclusion makes a good foundation for accurate calculation of GMAW droplet size and further droplet transfer control. |
