The project uses the VGG16 architecture combined with transfer learning to achieve binary classification detection of vehicle damage, and builds an interactive web application via Streamlit. The core goal is to promote the automation and scaling of insurance claims, providing technical support for fields such as insurtech, used car transactions, and fleet management. ## Project Background and Problem Definition Traditional vehicle insurance claims rely on manual inspection or photo review, which is inefficient and prone to backlogs during peak periods. With the growth in vehicle ownership, the industry urgently needs fast and accurate automated damage assessment solutions. Addressing this pain point, this project designs a deep learning-based binary classification system, aiming to provide a scalable and fast AI assessment tool to reduce manual review workload. ## Dataset and Model Architecture Analysis The project uses a custom vehicle image dataset containing 18,992 images (15,000 for training, 3,992 for testing), divided into two categories: undamaged (Class0) and damaged (Class1). The model uses VGG16 transfer learning: freezing pre-trained base layers to extract general features, with a custom classification head including a Flatten layer, a Dense layer with 256 neurons, a 0.5 Dropout layer, and a Softmax output layer. ## Technology Stack Selection and Training Performance The technology stack includes TensorFlow/Keras (deep learning framework), OpenCV (image processing), Streamlit (web deployment), and NumPy/Pandas (data processing). Training configuration: Adam optimizer, Sparse Categorical Crossentropy loss function. It achieved approximately 97% training accuracy in just 5 epochs, demonstrating the efficiency of transfer learning. ## Web Application Function Design Details The application has the following features: 1. Model caching mechanism (reused after first load); 2. Confidence threshold adjustment (sidebar slider for flexible adaptation to different scenarios); 3. Visual feedback (green for undamaged, red for damaged); 4. Channel consistency processing (automatic conversion from RGB to BGR format); 5. File upload support (JPG/JPEG/PNG, maximum 200MB). ## Practical Application Scenarios The system can be applied in: 1. Insurance claim automation (customers upload photos for automatic assessment and priority assignment); 2. Used car trading platforms (detect vehicle damage and mark listings that need review); 3. Fleet management (regular photo inspections to identify vehicles needing repair and optimize maintenance plans). ## Technical Insights and Future Outlook Advantages of the current architecture: transfer learning reduces data requirements, modular design, and engineering features (such as caching). Improvement directions: expand to multi-classification (damage level grading), add damage localization, multi-view fusion, and model lightweighting. The project demonstrates the potential of deep learning in the digital transformation of traditional industries. With a 97% accuracy rate and a simple interface, it has practical deployment value and provides technical reference for related fields.
