Explore, analyse and understand complex environments in unprecedented precision: UltraCam Dragon 4.1 is setting new standards in hybrid aerial mapping – and it‘s made by WILD.

Be it for urban modelling, corridor mapping or the creation of digital twins – the demand for precise geospatial data is huge. As they become increasingly essential for informed decisions, they need to be as precise and up-to-date as possible. This is where UltraCam Dragon 4.1 comes in. It is Vexcel‘s first aerial mapping system that combines hybrid oblique imaging with a cutting-edge LiDAR scanner in a single device.

AN ALL-IN-ONE POWERHOUSE
The UltraCam Dragon 4.1 produces high-resolution nadir and oblique aerial imagery enriched with precise LiDAR-based elevation information to create digital twins. They are generated by a powerful 2.4 MHz RIEGL OEM LiDAR scanner, which can collect up to 2 million measurements per second. Especially in tropical areas, the LiDAR‘s multiple target capability allows the collection of 3D ground points under thick vegetation. In cities with high buildings, its unique scanning geometry, including a true nadir scan line, ensures a comprehensive 3D data collection even in narrow building canyons. In addition, four oblique cameras (RGB) positioned at 45° in all cardinal points deliver sharp and crisp images. This combination renders the UltraCam Dragon extremely versatile. Moreover, its compact design allows for flexible integration in various aircraft platforms and easy maintenance.

PARTNERS FOR OVER 20 YEARS
In addition to the development work done by Vexcel, the system‘s perfection is also attributable to WILD‘s enormous production expertise. The company has been a contract manufacturer of high-tech cameras for over 20 years and currently produces five models. ”For us, WILD always stood out with state-of-the-art manufacturing facilities and diverse surface coatings. In addition to their remarkable adherence to delivery deadlines, we especially appreciate their expertise in assembling complex mechanical, optical and electronic components, which significantly enhances the quality of our products“, stresses Vexcel‘s Director of Operations Andreas Drumbl. Assembling the Dragon 4.1 is a complex process. ”The system combines a camera and a laser scanner in a single device, without taking up extra space. This requires a very compact and highly precise design“, explains Stefan Werkl, Head of Business Unit Optical Technologies at WILD. ”We assemble sensitive core components like camera modules and ensure precise adjustment of the sensors to the lenses. The final tests, too, are carried out in-house using specifically adapted test arrangements.“
