摘要:

客户越来越多地寻求快速有效的手段来快速和频繁地调查和沟通他们的建筑物的状况,以便在变得过于危险和昂贵之前,能够积极和及时地完成必要的维修和维护工作。这类工作的传统方法通常包括聘请建筑测量师进行状况评估,其中包括长时间的现场视察,以便系统地记录建筑物各部分的实际状况,包括建筑物更新、修理和维护的近期和预计长期费用的费用估计数。目前的资产状况评估程序非常耗时、费力和昂贵,并且对测量员构成健康和安全威胁,特别是在难以接近的高度和屋顶高度。本文旨在评估卷积神经网络(CNN)在自动检测和定位关键建筑缺陷方面的应用,例如,霉菌、变质和污渍。该模型基于VGG-16的预训练CNN分类器(后来与ResNet-50和Inception模型进行了比较),并使用类激活映射(CAM)进行对象定位。该模型在现实生活中的应用的挑战和局限性已经确定。该模型已被证明是强大的,能够准确地检测和定位建筑缺陷。该方法正在开发中,有可能扩大规模并进一步发展,以支持使用移动设备和无人机实时自动检测建筑物的缺陷和恶化。

英文摘要:

Clients are increasingly looking for fast and effective means to quickly and frequently survey and communicate the condition of their buildings so that essential repairs and maintenance work can be done in a proactive and timely manner before it becomes too dangerous and expensive. Traditional methods for this type of work commonly comprise of engaging building surveyors to undertake a condition assessment which involves a lengthy site inspection to produce a systematic recording of the physical condition of the building elements, including cost estimates of immediate and projected long-term costs of renewal, repair and maintenance of the building. Current asset condition assessment procedures are extensively time consuming, laborious, and expensive and pose health and safety threats to surveyors, particularly at height and roof levels which are difficult to access. This paper aims at evaluating the application of convolutional neural networks (CNN) towards an automated detection and localisation of key building defects, e.g., mould, deterioration, and stain, from images. The proposed model is based on pre-trained CNN classifier of VGG-16 (later compaired with ResNet-50, and Inception models), with class activation mapping (CAM) for object localisation. The challenges and limitations of the model in real-life applications have been identified. The proposed model has proven to be robust and able to accurately detect and localise building defects. The approach is being developed with the potential to scale-up and further advance to support automated detection of defects and deterioration of buildings in real-time using mobile devices and drones.
