Detection and quantification of concrete sidewalk damages

SNC-Lavalin Group Inc.是一家加拿大公司，为包括交通和基础设施在内的各种行业提供工程、采购和建筑服务。该公司配备了移动地图系统(MSS)和人行道检查车(SIV)。这些系统可以提取道路网络、路侧基础设施和人行道的地理空间和视觉信息。特别是，SNC Lavalin对人行道损坏的自动检测感兴趣。在这方面，CGQ将协助SNC Lavalin开发基于图像的解决方案，用于1)检测混凝土人行道的损坏并识别损坏类别，3)量化、测量和地理定位损坏程度。这一研究项目将使该公司能够配备功能性人行道损坏检测解决方案，并能够为其基础设施领域的客户提供尖端技术。对于加拿大市政当局和政府来说，这一解决方案可以在以下方面发挥重要作用：1)通过减少检查成本和时间消耗，优化其人行道管理计划的效率；2)通过及早发现和消除交通危险，提高人行道的安全性。

SNC-Lavalin Group Inc. is a Canadian company that provides engineering, procurement, and construction services to various industries, including transportation and infrastructure. The company is equipped with a Mobile Mapping System (MSS) and a Sidewalk Inspection Vehicle (SIV). These systems can extract geospatial and visual information of road networks, road-side infrastructure, and sidewalks. In particular, SNC Lavalin is interested in the automated detection of sidewalk damages. With this regard, CGQ will assist SNC Lavalin to develop image-based solutions for 1) detecting damages of concrete sidewalks and recognizing the damage category, 3) quantifying, measuring and geo-localizing the damage extent. This research project will allow the company to be equipped with a functional sidewalk damage-detection solution and be able to offer cutting-edge technologies to its clients in the infrastructure sector. For Canadian municipalities and governments, this solution can play a significant role in 1) optimizing the efficiency of their sidewalk-management plans by reducing inspection costs and time-consumption, and 2) increasing the safety of sidewalks by early detection and removal of trip hazards.
