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）是一家专门针对各种工程应用程序应用空中图像的公司，主要是对管道，电力公司和建筑物等基础设施的检查。据认为，ISW使用配备可见和感染相机的无人机（UAV），使用摄影测量技术生成3D地形产品。因此，这些产品已集成到虚拟管理系统中，通过该系统向客户提供技术服务。 2015年，ISW与魁北克中心（CGQ）合作，在应用研究项目（Anging Grant for Colleges）中合作。该项目主要旨在评估ISW的UAV光学系统（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，以筛选新的实践，无人检查的垂直基础设施。获得的结果表明，朝这个方向迈出了巨大的增长潜力。但是，在数据获取，数据处理和服务提供方面存在一些缺点。因此，ISW已与CGQ联系以开始这项为期三年的合作，以设计和开发专业的UAV-PS。该系统将能够克服传统的UAV-PS进行高精度3D测量和详细检查垂直基础设施（例如电信塔楼和建筑外墙）的缺点。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，在基础设施检查领域提供独特的技术，并满足其他各种其他精确工程服务的要求。
