Delair, a supplier of drone solutions for commercial industries, introduced the next generation of its high-performance Delair DT26X LiDAR UAV. According to the company, the DT26X is the industry’s first long-range fixed-wing drone to combine LiDAR sensing capabilities with an integrated high resolution RGB (red, green, blue) camera, increasing the precision, efficiency, and cost effectiveness of surveying and 3D mapping.

The Delair DT26X LiDAR’s combined payload of a lightweight sensor and integrated camera allows the acquisition of data in a single flight, which reduces cost and immediately provides an extremely detailed digital model of the inspected assets. The LiDAR sensor is specifically designed for UAV use, adding little weight or bulk to the Delair frame. The fully-integrated smart RGB camera enables real-time camera sensor control and in-flight photo review with automated quality checks.

The new platform delivers increased accuracy in 3D mapping and modeling of terrain and corridors in challenging physical environments (e.g. mountainous, inaccessible by road or foot, dense vegetation) and with difficult visibility, lighting or weighting conditions. Its long range flying capabilities – allowing coverage of up to 2,400 square acres, communication range of 30 kilometers and 100 minutes of flight time – improve the efficiency of aerial mapping operations over large areas. As a result, the Delair DT26X LiDAR is well suited for uses such as environmental and land surveys, infrastructure surveillance, powerline and pipeline inspections, and road and rail construction.

“The combination of a sophisticated LiDAR sensor and an industrial grade RGB camera removes the ‘either/or’ decision of choosing between LiDAR and imagery data acquisition for geospatial professionals. This is the most versatile and cost-effective UAV solution for large area, long range mapping and surveying where accuracy and detail are required,” says Chase Fly, geospatial product manager at Delair.

The Delair DT26X LiDAR is the first fixed-wing UAV to incorporate the new RIEGL miniVUX-1DL LiDAR sensor, a specially designed device for the needs of UAV use. The small form factor sensor includes a downward looking and optimized, 46° degree field of view and the circular scan pattern provides a very high point density and point distribution.

It offers a high scan speed of up to 150 scans/sec and a measurement rate of up to 100,000 measurements/sec. It is effective in penetrating poor lighting conditions or dense foliage. The LiDAR sensor makes use of RIEGL's Waveform-LiDAR technology, allowing echo digitization and online waveform processing. It supports multiple-target resolution – up to five target echoes per laser shot.
