A coal mine drill pipe counting method |
| abstract |
The invention discloses that the invention relates to the field of coal mine drilling safety, and in particular relates to a method for counting drill pipes in coal mines, which includes: screening drill pipe area images in a drill pipe monitoring video, and establishing a coordinate set of a rectangular frame circumscribing the drill pipe outline; The coordinates of the rectangular frame circumscribing the rod profile include the coordinates of the center point of the rectangular frame circumscribing the drill rod profile; extracting the coordinates of the center points of the rectangular frame circumscribing all the drill rod profiles, and establishing a continuous area of coordinates of the center points of the rectangular frame circumscribing the drill rod profile; The filtering process is performed to obtain an inverse parabola-like curve, and each trough of the inverse parabola-like curve is counted once, and each count is a count of a coal mine drill pipe. The technical solution of the present application effectively solves the situation that the coal mine drill pipe cannot be accurately and automatically counted in the prior art. |
