Abstract:

As for the difficulty in analysing the trajectory charging of the current blast
furnace,the pattern recognition technique is introduced and the mesurement method of the
polar coordinate laser grid is proposed. To contrast the edge analysis of trajectory
charging,we calculate the threshold value by linear probing. According to the image quality
of trajectory charging in the difference spectrum,the characteristic radius is analysed and
defined at the same time to different lengths of the characteristic radius for attaining
accurate trajectory charging data information,the trajectory charging in polar coordinate is
reconstructed,and the automatic control information of the blast furnace is obtanied.
