摘要
In order to improve the intelligent level of coal mining face,this paper proposes a novel coal-rock recognition method based on the fusion of image and laser point cloud. Firstly,the three-dimensional reconstruction is used to realize the construction of coal-rock image point cloud containing color information and cutting texture features. Secondly,a coal-rock point cloud registration algorithm based on improved iterative closest point (ICP)algorithm is proposed to improve the search speed and accuracy between point pairs. Then,a coal-rock recognition method based on improved regional growth algorithm is designed. The effectiveness of the improved measures is verified by simulation analysis. The self-established coal-rock cutting experimental system is set up,and the experimental comparison and analysis of the improved ICP and region growth algorithm are carried out. The results indicate that the point cloud data segmentation effect of the proposed method is the best and the accuracy of coal-rock recognition can reach to 92.95%. The field test is carried out in the underground coal face,which further proves the practicability and feasibility of proposed coal-rock recognition method. © 2023 Nanjing University of Aeronautics an Astronautics.
