Detection and quantification of concrete sidewalk damages

SNC-Lavalin Group Inc.是一家加拿大公司，为各种行业提供工程，采购和建筑服务，包括运输和基础设施。该公司配备了一个移动的测绘系统（MSS）和一个人行道检查车（SIV）。这些系统可以提取道路网络、路边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。该研究项目将使该公司能够配备功能性的人行道损坏检测解决方案，并能够为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，该解决方案可以在以下方面发挥重要作用：1）通过降低检查成本和时间消耗来优化人行道管理计划的效率，以及2）通过早期检测和消除绊倒危险来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.
