Structural Health Monitoring (SHM) ensures the safety and longevity of infrastructure by enabling timely damage detection. Vision-based crack detection, combined with UAVs, addresses the limitations of traditional sensor-based SHM methods but requires the deployment of efficient deep learning models on resource-constrained devices. This study evaluates two lightweight convolutional neural network models, MobileNetV1x0.25 and MobileNetV2x0.5, across TensorFlow, PyTorch, and Open Neural Network Exchange platforms using three quantization techniques: dynamic quantization, post-training quantization (PTQ), and quantization-aware training (QAT). Results show that QAT consistently achieves near-floating-point accuracy, such as an F1-score of 0.8376 for MBNV2x0.5 with Torch-QAT, while maintaining efficient resource usage. PTQ significantly reduces memory and energy consumption but suffers from accuracy loss, particularly in TensorFlow. Dynamic quantization preserves accuracy but faces deployment challenges on PyTorch. By leveraging QAT, this work enables real-time, low-power crack detection on UAVs, enhancing safety, scalability, and cost-efficiency in SHM applications, while providing insights into balancing accuracy and efficiency across different platforms for autonomous inspections.

视觉Transformer（ViT）正在出现，在计算机视觉任务中具有显著提高的准确性。然而，其复杂的体系结构和巨大的计算/存储需求迫切需要新的硬件加速器的设计方法。这项工作提出了一个FPGA感知的自动ViT加速框架的基础上提出的混合方案量化。据我们所知，这是第一个基于FPGA的ViT加速框架，探索模型量化。与最先进的ViT量化工作（算法方法，只有没有硬件加速）相比，我们的量化实现了0.47%至1.36%的高的Top-1精度在相同的位宽。与32位浮点基线FPGA加速器相比，我们的加速器的帧速率提高了约5.6倍（即，56.8 FPS vs. 10.0 FPS），DeiT-base在ImageNet数据集上的准确率下降了0.71%。
