摘要

为解决露天矿区复杂环境下浮石识别与特征提取的技术难题，提出了一种基于动态卷积改进型金字塔解析网络模型的浮石检测与三维重建方法。针对浮石区域分布复杂、小目标特征难以捕获的问题，优化金字塔解析网络模型，引入动态卷积和通道注意力机制，增强特征提取能力和分割精度；结合ZED双目相机获取的深度图，与分割结果生成三维点云模型，通过凸包算法实现浮石几何特征和体积的精准测量。在自制浮石数据集上的试验表明，改进模型的mIoU达到81.94%

比原始模型提升5.49百分点；mDice和mPA分别提升至90.90%和89.98%;体积、质量、形状因子和初始高度识别的平均准确率分别达到87.65%、85.55%、82.38%和96.15%。研究表明，改进的金字塔解析网络模型在复杂矿区环境中展现出卓越的浮石检测与几何信息提取能力，为矿区浮石清理与安全评估提供了可靠的技术支持。

Abstract

Loose rocks scattered on open-pit slopes pose significant safety hazards to mining operations by threatening equipment

workers

and production stability. To address the limitations of traditional laser scanning and manual inspection methods

this study develops an enhanced Pyramid Scene Parsing Network(PSPNet) combined with stereo vision-based 3D reconstruction for precise loose rock detection and quantitative feature extraction. The original PSPNet is improved by integrating dynamic convolution

depthwise separable convolution

and Squeeze-and-Excitation(SE) attention mechanisms. These modifications significantly enhance the network's ability to capture multi-scale features and details of small objects while maintaining computational efficiency. A custom dataset comprising 1 205 annotated images of loose rocks was created

encompassing diverse lighting conditions

rock sizes

and complex backgrounds. Extensive data augmentation techniques—such as rotation

scaling

brightness adjustment

Gaussian noise addition

and flipping—were applied to improve the model's robustness. Model training was conducted using PyTorch over 500 iterations on an NVIDIA RTX 4060 GPU

ensuring convergence and stable performance. The segmentation results indicate that the improved PSPNet achieved a mean Intersection over Union(mIoU) of 81.94%

representing a 5.49 percentage-point improvement over the baseline PSPNet. Meanwhile

the mean Dice coefficient and pixel accuracy increased to 90.90% and 89.98%

respectively

confirming its superior capability to delineate small and irregular rock boundaries. Comparative experiments with U-Net

Segformer

DeepLabV3

Mask2 Former

and ConvNeXt further validated the enhanced model's overall advantages across multiple evaluation metrics. For geometric analysis

ZED stereo cameras were employed to acquire depth maps

which were fused with segmentation masks to generate 3D point clouds. A convex hull algorithm

combined with dynamic regional optimization and depth-weight correction

enabled accurate reconstruction of rock morphology. The estimation accuracies for rock volume

mass

shape factor

and initial height reached 87.65%

85.55%

82.38%

and 96.15%

respectively. In conclusion

the proposed framework effectively integrates deep learning-based segmentation with stereo vision-driven 3D reconstruction

providing a reliable tool for loose rock detection

quantitative hazard assessment

and safety management in open-pit mining environments. This study not only enhances the precision of rock feature extraction but also contributes to advancing intelligent monitoring and risk control technologies in complex mining operations.
