System and method for on-line measuring a burden surface in a blast furnace

Abstract

The present invention discloses a system and method for on-line measuring a burden surface in blast furnace to get burden surface information. The system comprises laser emitter(s) disposed above the burden surface and emitting laser beam(s) to continuously scan at least one portion of the burden surface; a video camera configured to shoot burden surface images, each of which comprises a detection point pattern formed by the laser beam incident on the burden surface; an image processing device configured to receive the burden surface images transferred from the video camera and output the burden surface information. As compared with the prior art, the present invention may substantially reduce the cost of the measuring system and obtain burden surface information sufficiently accurate with a large number of actual detection points. Furthermore, the system for on-line measuring a burden surface in blast furnace according to the present invention may use less number of laser emitter (even one laser emitter), so it is more advantageous to minimize the system and may simplify laser emitter protective measures.
