Live from Intergeo 2023 in Berlin: Vexcel Imaging is thrilled to announce the innovative UltraCam Dragon 4.1, representing the market’s most advanced, progressively designed, and seamlessly integrated hybrid aerial mapping system.  Designed for high-resolution mapping of complex urban environments and the creation of precise digital twins, the UltraCam Dragon combines the very best in imaging and LiDAR technologies for maximum collection productivity, high-accuracy and improved target coverage.
“I am thrilled that we can offer the UltraCam Dragon 4.1, a system that opens up new perspectives for our customers,” states Alexander Wiechert, CEO of Vexcel Imaging. “The UltraCam Dragon 4.1 exemplifies our commitment to innovation and excellence in aerial mapping technology. It is poised to make a significant impact on industries and applications worldwide by providing the technology needed to explore, analyze, and understand complex environments like never before.”
The new UltraCam Dragon 4.1 produces high-resolution nadir and oblique aerial imagery enriched with precise elevation information obtained by a powerful 2.4 MHz RIEGL OEM LiDAR scanner, collecting up to 2 million measurements per second. The LiDAR’s innovative multi-axis scanning geometry, including a true nadir scan line, ensures maximum coverage of vertical features without occlusion in the steepest of building canyons and interior courtyards for truly impressive and complete digital twins. Two high-resolution nadir sensors (RGB Bayer pattern and NIR), along with four oblique (RGB) sensors, consistently deliver sharp, accurate and crisp imagery. This is achieved through advanced image processing techniques, including Vexcel’s proprietary Adaptive Motion Compensation (AMC) and True Pixel Processing (TPP). The integration of these best-in-class sensors results in a comprehensive and multi-dimensional information gain, facilitating in-depth analysis and a profound understanding of the as-built environment.
“We are delighted that Vexcel has chosen the RIEGL VQ-680 OEM LiDAR module to integrate into their brand new, radical UltraCam Dragon 4.1 system design and thank our friends and colleagues at Vexcel for their trust and wish them all the best for a successful go to market with this new product” commented Dr. Johannes Riegl, CEO of the RIEGL Group on the cooperation between the two, long-term connected companies, both headquartered in Austria.
The system marks Vexcel’s first hybrid aerial mapping system for deep insights into complex environments at highest collection rates. The integrated LiDAR scanner, a RIEGL VQ-680 OEM sensor, has been unveiled to the market at Intergeo in Berlin, with Vexcel being the first company in the world to integrate this cutting-edge LiDAR scanner into a turnkey solution.
With the introduction of the UltraCam Dragon 4.1 and UltraCam Merlin 4.1 at Intergeo, Vexcel is expanding its offerings of aerial systems to cater to a wider range of applications in airborne photogrammetry. The 4th generation UltraCam product lineup now encompasses three distinct categories: the Premium line, comprising of the highly successful UltraCam Eagle 4.1, UltraCam Osprey 4.1, and UltraCam Condor 4.1 cameras with their established high-resolution panchromatic sensors; the Fundamental line, which consists of aerial cameras based on Bayer pattern sensors like the UltraCam Merlin 4.1 models; and the Integrated line, showcased by the newly unveiled UltraCam Dragon 4.1. This cutting-edge hybrid aerial mapping system combines LiDAR and image sensors, providing advanced capabilities for integrated data acquisition.
The new Dragon 4.1 system will be available in summer 2024.
