This Small Business Innovation Research (SBIR) Phase I project will investigate the technical and commercial feasibility of designing a video-based roof surveying software. Roof surveying is an essential activity in sheet metal roofing projects. Several technologies have been evolved over the years for this purpose; however, none of them are safe, inexpensive, automatic, and accurate enough at the same time. Tape measurement is therefore still the standard practice despite its apparent limitations. This project will address this need by automatically generating an accurate 3Dwirediagram of a roof which includes necessary measurements. If successful, it will be the world?s first videobased roof surveying software that fulfills all industry requirements (accuracy, simplicity, cost, safety, and efficiency). When using it, a roofing contractor simply collects stereo video from a roof and sends it to a server for processing. Unlike existing vision-based software that only use point level information, the software uses a hybrid formulation that combines points, lines, and planes. This higher level information enhances the output accuracy to the required level. Once measurements are automatically extracted and sent back, the contractor uploads them to an on-site roll forming machine to roll form and cut sheet metal coil into precise, ready to install panels.The broader impact/commercial potential of this project is to address inherent deficiencies of current technologies for roof surveying and bring the sheet metal roofing trade up to the modern standards of CAD/CAM used in many other industries. Compared to tape measuring, this project will significantly reduce measuring costs and also eliminate the exposure of employees to fall hazards, thereby decreasing the very high number of occupational injuries and fall deaths which occur in the roofing industry (7% of private construction fatalities in 2009). The simplicity of the application will remove the need for trained surveyors which are required for surveying with a total station. It could also provide more accurate measurements compared to satellite imaging technology and hence satisfy industry requirements.Beyond the target industry (i.e., sheet metal roofing), this solution could be used by virtually any roofing contractors worldwide. It could also be adapted to many of the other building trades where as-built documentation is required to build components, including metal façade manufacturers/installers and HVAC contractors. This, in turn, will result in time and cost savings, which can improve the efficiency of the construction industry. Surveying equipment manufacturers and surveying companies are the other key players in the target market of this application.

这项小型企业创新研究（SBIR）I阶段项目将研究设计基于视频的屋顶测量软件的技术和商业可行性。屋顶测量是钣金屋顶项目中的重要活动。多年来，为此目的已经进化了几种技术。但是，它们都不是安全，便宜，自动和准确的同时精确的。因此，尽管具有明显的局限性，但磁带测量仍然是标准做法。该项目将通过自动生成屋顶的准确3Dwirediagram来满足这种需求，该图包括必要的测量。如果成功，将是世界上第一个满足所有行业要求（准确性，简单，成本，安全性和效率）的首个视频屋顶测量软件。使用时，屋顶承包商只需从屋顶收集立体声视频，然后将其发送到服务器进行处理。与仅使用点级信息的现有基于视觉的软件不同，该软件使用结合点，线和飞机的混合公式。此更高级别的信息将输出精度提高到了所需的水平。一旦将测量值自动提取并退回，承包商就会将其上传到现场滚动机器上，将其切成卷和将钣金线圈切成精确，准备安装面板。该项目的更广泛的影响/商业潜力是解决当前技术固有的缺陷，以用于屋顶测量和将板板金属屋顶交易与许多现代工业相关的现代工业/摄像机销售，以实现许多其他工业/摄像机。与磁带测量相比，该项目将显着降低衡量成本，并消除员工遭受危害的暴露，从而减少屋面行业中发生的很高的事件伤害和跌倒死亡（2009年占私人建筑死亡的7％）。应用程序的简单性将消除对训练有素的测量师的需求，这是与总站进行测量所需的。与卫星成像技术相比，它还可以提供更准确的测量，从而获得满意度行业的要求。目标行业（即钣金屋顶），几乎所有屋顶承包商都可以使用该解决方案。它也可以适用于许多其他建筑行业，在这些交易中，建造组件（包括金属立面制造商/安装商和HVAC承包商）所需的文档需要进行。反过来，这将节省时间和成本，从而提高建筑业的效率。测量设备制造商和测量公司是该应用程序目标市场中的其他主要参与者。
