Construction Site Detection System This project uses YOLOv8 and PyQt5 to create a real-time construction site detection system. The system detects various elements such as workers wearing safety helmets, concrete transport vehicles, dump trucks, mixers, excavators, rollers, bulldozers, and loaders on a construction site. ## Installation 1. Clone the repository: bash git clone https://github.com/yourusername/construction-site-detection.git cd construction-site-detectionInstall dependencies:pipinstall-rrequirements.txtSet up environment variables (optional):exportDATASET_PATH./datasets/construction_site/exportMODEL_PATH./runs/detect/train/weights/best.ptexportIMG_SIZE640exportBATCH_SIZE16exportEPOCHS50exportCONF_THRESHOLD0.5TrainingTo train the YOLOv8 model:python train.pyRunning the GUITo run the graphical user interface:python UIProgram/MainProgram.pyUsage TutorialSee 使用教程.xt for detailed usage instructions.### 4. 运行步骤 1. **确保数据集路径正确** - 将您的数据集放在 datasets/construction_site 目录下。 - 确保图像和对应的标签文件存在并且格式正确。 2. **安装必要的库** - 确保您已经安装了所需的库如 torch, torchvision, ultralytics, pyqt5, opencv-python 等。 - 您可以使用以下命令安装这些库 bash pip install -r requirements.txt 3. **运行代码** - 首先运行训练代码来训练YOLOv8模型 bash python train.py - 然后运行GUI代码来启动检测系统 bash python UIProgram/MainProgram.py hope这些信息能帮助您顺利构建基于YOLOv8和PyQt5的智慧化工地管理系统。
