Delair introduces DT26X LiDAR UAV

Delair has introduced the new Delair DT26X LiDAR UAS for light distance and ranging (LiDAR)-based aerial surveying and 3D mapping applications, the company announced on 5 February.

The fixed wing UAS combines the new RIEGL miniVUX-1DL LiDAR sensor with an integrated high resolution RGB camera. The fully-integrated smart RGB camera enables real-time camera sensor control and in-flight photo review with automated quality checks.

The small form factor LiDAR sensor includes a downward looking and optimised field of view specifically geared for corridor mapping tasks. The wedge prism scanner construction produces a field of view of 46 degrees, and the circular scan pattern provides a very high point density and point distribution.

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

The Delair DT26X LiDAR’s combined payload of a lightweight sensor and integrated camera allows the acquisition of LiDAR and photogrammetry data in a single flight which provides detailed digital model of the inspected assets.

The UAS' flying capabilities – allowing coverage of up to 2,400 square acres, communication range of 30km and 100 minutes of flight time – improve the efficiency of aerial mapping operations over large areas. This makes the solution suitable for applications including environmental and land surveys, forestry monitoring, infrastructure surveillance, powerline and pipeline inspections, and road and rail construction.
