    A method for evaluating the accessibility of underground auxiliary transportation vehicles in coal mines based on multi feature fusion by Fan JIANG, Yifan LIU, Zhencai ZHU, Chaofan ZHANG, Gongbo ZHOU, Yuxing PENG

    Published 2024-12-01
    “…Progressive probability Hough transform and Catmull Rom spline curve with improved feature point selection are used to fit the straight track and curved track separately, forming a railway track detection method based on a switchable model; Secondly, based on the color attributes of coal mine underground tunnel wall pipelines, a pipeline feature detection strategy is constructed through HSV color space transformation, edge detection, and least squares fitting algorithms; Once again, a weighted fusion method based on pipeline and rail feature points is proposed to extract the centerline trajectory of auxiliary transportation vehicles, and to construct rules for generating safe passage areas for auxiliary transportation vehicles; Then, for the over-segmentation problem in the traditional watershed algorithm, two-dimensional edge and area feature extraction of static obstacles is carried out by using improved watershed segmentation based on markers and GraphCut algorithm, and a small-sample classification support vector mechanism is selected to build a pedestrian detection model based on the fusion of HOG (Histograms of Oriented Gradients)features and LBP(Local Binary Pattern) features for underground coal mine, so as to realize the comprehensive detection of dynamic and static obstacles in front of auxiliary transportation vehicles; Finally, the positional relationship between obstacles and safe passage area is judged by Euclidean distance to determine the obstacle invasion, and the results of auxiliary transportation vehicle passability assessment are obtained. …”
