Industrial Skyworks (ISW) is a company specialized in applying aerial imagery for various engineering applications, mainly the inspection of infrastructures such as pipelines, electric utilities and buildings. Accordingly, ISW uses an unmanned aerial vehicle (UAV) equipped with visible and infrared cameras, to generate 3D topographic products using photogrammetric techniques. These products are, then, integrated to a virtual management system, through which technical services are offered to its clients. In 2015, ISW collaborated with Centre de géomatique du Québec (CGQ) within an applied research project (Engage Grant for colleges). The project mainly aimed at assessing the metric quality of the geo-referencing solutions provided by ISW's UAV-photogrammetry system (UAV-PS). Additionally, an interesting feasibility study was conducted to screen a new practice, unmanned inspection of vertical infrastructures. The obtained results revealed a great growth potential for the company in this direction. However, several shortcomings in terms of data acquisition, data processing and service provision were identified. Therefore, ISW has contacted CGQ to start this three-year collaboration in order to design and develop a specialized UAV-PS. This system will be able to overcome the shortcomings of a conventional UAV-PS to perform high-precision 3D measurements and detailed inspection of vertical infrastructures, such as telecommunication towers and building facades. This applied-research project will allow ISW to improve its leading expertise in the field of aerial data analytics, to offer a unique technology in domain of infrastructure inspection, and to meet the requirements of a large variety of other precision-engineering services.

Industrial Skyworks（ISW）是一家专门将航空图像应用于各种工程应用的公司，主要是管道、电力设施和建筑物等基础设施的检查。因此，ISW使用配备可见光和红外摄像机的无人机（UAV），使用摄影测量技术生成3D地形产品。然后，这些产品被集成到一个虚拟管理系统中，通过该系统向客户提供技术服务。2015年，ISW与魁北克地理中心（CGQ）合作开展了一个应用研究项目（高校参与补助金）。该项目主要旨在评估ISW的无人机摄影测量系统（UAV-PS）提供的地理参考解决方案的度量质量。此外，还进行了一项有趣的可行性研究，以筛选一种新的实践，即垂直基础设施的无人检查。所取得的成果显示了该公司在这一方向上的巨大增长潜力。然而，在数据获取、数据处理和服务提供方面发现了一些不足之处。因此，ISW已经联系CGQ开始了为期三年的合作，以设计和开发一种专门的UAV-PS。该系统将能够克服传统UAV-PS的缺点，对垂直基础设施进行高精度3D测量和详细检查，如电信塔和建筑物立面。该应用研究项目将使ISW能够提高其在航空数据分析领域的领先专业知识，在基础设施检测领域提供独特的技术，并满足各种其他精密工程服务的要求。
