Using the Unmanned Aerial Vehicle (UAV) from Leica Geosystems to create highly precise data for bridge inspections, customer companyAiviewGroup每年都在测量，维护和检查4,000多个基础设施建筑方面取得了成功。

作为第一个国家公路建设尤其ally for motor vehicles, Italy introduced the autos trade. First built in 1921, the high-speed roadways have continued to expand ever since. Owned by the Italian government but maintained and operated by a group of concessionaires for profit, the largest of these companies is theAutostrade per I’Italia，在意大利维修3,408公里，从巴西到印度管理了5,000多公里的道路。

Infrastructure inspections from the air

Within its network of 3,408 km roadways,l'Italia的自动贸易has to maintain more than 4,200 bridges, viaducts and tunnels. Every bridge must be visually inspected twice a year by law with a more in-depth inspection with an engineer on a yearly cycle. With this large number of bridges to inspect in mind,l'Italia的自动贸易was looking for more efficient ways and started a collaboration withAiviewGroup在机器人解决方案上。

“We have been doing UAV bridge inspections with this UAV since 2012,” says Nicola Marietti, bridge inspector withAiviewGroup. “We found the visionary within this customer and have built some success while developing specific software and methods for managing bridge inspections with a UAV at the centre of the information technology solution.”

The special mount for a camera on the top of the UAV from Leica Geosystems allows the crew close-up looks under the deck and in tight spots. The use of professional pilots to control the UAV ensures safety for the controlling crew underneath the bridge and to process the collected data.AiviewGroup已经开发了一种算法来评估拍摄图片并检测出针对缺陷分类学库的问题。

玛丽埃蒂说：“我们有一个明确的程序，可以更好地了解桥梁可能发生什么样的问题以及如何向客户报告。”“该算法为基础结构的不同元素提供了状态。我们检查水泥，桥铁，植被和一般环境的问题。”

Even though the software takes care of the analysis and reporting, there is still a heavy human element in the workflow for conducting each bridge survey and verifying the autonomously created reports with the knowledge of a civil and structural engineer.

TheAiviewGroup已经创建了云平台AI检查，在该检查中，公司管理客户的所有资产。从计划到现场工作分析，可以在此软件中完成检查的整个工作流程。

技术方法AiviewGroupand their partners came up with makes it possible to inspect bridges without shutting down the traffic. A usual inspection would require at least one line to be shut down in order to inspect the bridge. Furthermore, UAVs require much smaller crews, which reduces the costs for the client. Instead of a special highway vehicle and three-person crew with an arm and bucket for placing the inspector under the bridge, and the corresponding six-person traffic safety personnel, the UAV works below traffic with a three-person crew. A further cost saving comes from the reduced time it takes for each inspection using the UAV.

Added value for inspections

With all these advantages in mind,AiviewGroupinsists that when it comes to robotics and automation, a team with specialties and professionalism is always required for the demands of high precision inspection and analysis.

“The risk is high on every flight, and we fly between four and six hours in a day when we go out to do inspections,” says Marietti. “We move methodically in a difficult environment for the whole day. It’s impossible to do this job without specialised people.”

每次检查均遵循相同的模式。在与无人机起飞之前，大约30％的时间和精力用于计划飞行。当场，多功能器是主要工具，以及在飞行过程中进行实时评估的监视器站。实际飞行最多占整体任务的10％，其余60％​​用于处理收集数据的后处理，评估和显示。

To use UAVs and other automated data collection tools for surveying and inspecting infrastructural constructions is a big step up in ways engineers will work in the future. Redefining these workflows with the newest technology is a disruption with traditional surveying, but the data that can be collected now makes this approach byAiviewGroupa much more informative input for clients and engineers.

This high quality data is based on traditional imagery sensors as the source of information. With these methods already working, there are still more options to combine the possibilities of an UAV and sensor technologies which collect comprehensive data to evaluate the state of a construction (e.g., the use of hexacopter platform fitting LiDAR sensors in order to create high-accuracy 3D models or thermal sensors to detect defects causing heat due friction). Multispectral or hyperspectral sensors would allow customers to get the materials fingerprint and to analyse the material properties of the area that has been captured, giving insight on detailing species type and even mineral properties of the ground below.

为了敦促无人机的自主性特征，甚至有机会通过使用Teach-In功能来自动化飞行，因此直播可以反复以相同的方式飞行以收集同一区域的可比较数据。

Giving the possibilities to adapt nearly every sensor needed onto the UAV and into the workflow, the industrial UAV is a sensor platform rather than just an imaging platform. There are many more possible applications and insights when the “eye in the sky” is given superpowers that make it capable of sensing and capturing far more than we can see.
