Arrowhawk成像选择超级鹰以进行空中映射

Arrowhawk Imaging选择了具有100mm镜头的Ultracam Eagle Mark 3空中摄像头系统作为其第一个空气寄生成像系统。自2019年从Vexcel Imaging购买传感器并将设备安装在Cessna 206单引擎飞机中以来，该地图公司已成功完成了许多项目。

Arrowhawk的金融与企业业务总监Lance McKeever说：“我们认识到对航空影像的需求和多种用途，并希望以具有大幅面传感器的服务提供商进入市场，以完成中型到大型项目。”“ Vexcel的技术为我们提供了竞争优势，因为鹰马克3has a very large footprint and fast frame rate, which leads to more efficient flying without sacrificing high quality and accuracy.”

The UltraCam Eagle is capable of capturing 10cm GSD at 5,000m above the ground. At this high elevation, the 450MP footprint collects more data in less time, shortening the hours needed for collection and optimizing flying windows.

“除了出色的相机性能外，Vexcel提供的服务水平远远优于市场上的任何其他公司，” McKeever说。“根据我们的经验，Vexcel将尽一切努力使我们的公司在尽可能少的时间内运作，这又使我们成为更可靠的合作伙伴。”

Planning Flights from a Photogrammetric Perspective

Thrasher Group是一个完善的建筑，工程和现场服务提供商，可处理所有图像处理和增值产品开发箭头。该团队使用Vexcel的摄影测量后处理软件使用Ultramap，迅速从每次UltraCAM飞行中生成高质量的数据产品。高度自动化的处理能力加快了工作流程，并且超大型速率可扩展，可以通过在数千个内核中并行处理数据来满足短期线。

除了高级传感器技术，UltraNav softwareprovides integrated flight management and georeferencing to optimize UltraCam missions. “We plan the flights from a photogrammetric perspective to ensure the results meet the customers’ requirements,” said Craig Fry, chief photogrammetrist and aerial mapping manager for Thrasher Group. “On days that wind or turbulence isn’t conducive to image collection, UltraNav is an advantage because of the leeway it allows the pilot and the ability of the IMU to address drift through the mount. On numerous missions in challenging conditions, the data collected was great and we didn’t have to incur added expenses to refly.”

For large projects such as county-wide collections, the large-format Eagle covers the area of interest in a smaller number of flight lines and produces highly accurate imagery with fewer seam lines and better colour consistency.

“We hope to gain a name for ourselves by partnering on large projects, since we know the sensor and software we have allow us to complete missions and deliver products in minimal time,” McKeever stated. “Based on the past two years of operations, we are confident that we can do exactly what our clients want by providing quality service and first-rate imagery at a high level of efficiency.”
