The invention discloses a
laser scanning type bulk
material flow detection and distribution error
elimination method. Collecting
point data and
belt speed data of frames of section contours of a material
stream are obtained; three-dimensional coordinates are built according to collecting
point data and
belt speed data; the
material flow between adjacent frames is obtained through a
triangulation network construction method, and the instantaneous flow rate of a unit time is obtained; the material
stream sectional area is worked out by calculating the area difference between a material and a no-load belt scanned by a
laser scanner, the area R defined by the straight line where the starting angle of each frame scanned by the
laser scanner is located, the straight line where the termination angle of the frame scanned by the laser
scanner is located and the corresponding material
stream section contour in the material conveying process is calculated, and the material stream sectional area of each frame is obtained; the sectional area distribution error correction factor of the kth frame of the material stream is obtained; the corrected material stream sectional area is calculated. The
laser scanning type bulk
material flow detection and distribution error
elimination method is simple in structure, high in
automation degree and high in real time performance, and
material distribution measurement is not influenced by dust, the weather, light and the like in the external environment.
