Abstract
A molten-state suspended ellipsoidal droplet image processing algorithm is based on dual-camera vision. The algorithm includes acquiring images of a standard sphere by means of two cameras, and calculating the actual size corresponding to each individual pixel of the two standard sphere images; synchronously acquiring two images of a droplet by using the two cameras at a specified included angle; establishing an ellipsoidal quadric surface equation for the droplet, respectively detecting edge contour lines of the two images, and establishing elliptical contour line equations for the edge contour lines; introducing a specified included angle, and constructing an equation set according to relationships between parameters of the two elliptical contour line equations and the ellipsoidal quadric surface equation; solving the equation set to obtain the length of each semi-axis of the droplet; and calculating the volume of the droplet according to the length of each semi-axis.
