Research on end-to-end multi-target detection of unmanned mine car road obstacles in open-pit mines
摘要
Abstract
Mining engineering is rapidly developing towards automation and intelligence,and the construction of intelligent mines has become a future trend.The multi-objective environmental perception of unmanned mine cars in open-pit mine areas is a key step in unmanned transportation.For the safety risks caused by multiple obstacles such as rolling pits,puddles,vehicles and personnel in complex unstructured roads,the existing end-to-end algorithms face the challenges of small target information loss,insufficient multi-scale feature fusion,unbalanced samples,and difficulty in balancing model complexity and accuracy in the dynamic and complex en-vironment of open-pit mines.To this end,an end-to-end multi-target detection model You Only Look Once-Mine Multi-target Detec-tion(YOLO-MMD)for unmanned mine trucks in open-pit mines is proposed.For the problem of missing observation pixel informa-tion caused by unstructured terrain in open-pit mines,Space-to-Depth Convolution(SPD-Conv)is introduced to transform image spatial information into depth information,which effectively preserves the fine-grained perception ability of small targets in unstruc-tured scenes and improves computational efficiency.In order to improve the effective use of context information,Efficient Multi-Scale Attention(EMA)is embedded in the detection layer to realize pixel-level cross-channel interaction and spatial information ag-gregation,which enhances the ability of multi-scale feature fusion without significantly increasing the computational burden.In addi-tion,considering the sample imbalance problem of different obstacle target objects in open-pit mines,the In-Focaler-IoU loss func-tion is designed to improve the efficiency and convergence speed of bounding box regression with auxiliary bounding box while pay-ing attention to rare target samples.The study show that YOLO-MMD can detect multi-target objects under the conditions of occlu-sion and blurring,and achieve the best balance between multi-target detection accuracy and complexity.It can achieve 0.939 mAP,4.56 MB model size and 5.8 G floating-point operations per second,which can provide effective and feasible environmental percep-tion for the safe driving of unmanned mine cars.关键词
