Aibot X6 V2 Nano-Hyperspec camera15 September, 2015
Hyperspectral camera as serial product for industry multicopters
From now on, AibotX6 could also be supplied with a Headwall Nano-Hyperspec® camera
Kassel/Stuttgart, September 15, 2015 – Following its premiere at last year’s INTERGEO in Berlin, the fully integrated solution for a hyperspectral camera fitted to the AibotX6 UAV (Unmanned Aerial Vehicle) is being presented as a serial product this year. Headwall’s Nano-Hyperspec® camera has been optimized for weight, size and performance for airborne use. Now that the test phase of an AibotX6 with integrated Headwall sensor has been concluded successfully, the first serial solutions have been produced ready for delivery after the INTERGEO 2015 exhibition.
The fields of application for this technology are as diverse as the specific demands made on an optical sensor system for remote sensing. Whether it is a question of spatial scanning, spectral scanning, a combination of both (spatio-spectral scanning), or simply taking a “snapshot” – the importance of hyperspectral scanning is increasing in a wide variety of industries. The generation of information based on the evaluation of light signals in the wavelength range from 400 nm (ultraviolet) to 1,000 nm (infrared) is growing in significance, especially in the areas of agriculture and forestry, geology, environmental monitoring, disaster relief and prevention, security or the planning of large-scale construction and industry projects.
To date, use of this technology was restricted mainly to satellites, fixed-wing aircraft and helicopters, so the combined solution of Headwall’s (Headwall Photonics Inc., Fitchburg, USA) Nano-Hyperspec® camera and the AibotX6 Version 2 offers a new, advanced level of precision data generation. As the camera is fitted to the latest generation of hexacopter, it can overfly fields or vineyards at extremely low altitude and greatly reduced cost, delivering images that contain data on chlorophyll content, plant health and the presence of pests. These images, in turn, give farmers vital information about the state of their crops and harvest prospects. For close-up geological mapping purposes, landfill sites and open-cast mines can be surveyed from the air to detect precious metals or minerals quickly and efficiently. Aerial surveying with a UAV and hyperspectral camera can show reliable evidence of soil or water pollution quickly and without risk to the health of human operators, or detect anomalies in the terrain prior to construction work, which can then be taken into account when planning complex building projects.
Lightweight with heavyweight performance
The dimensions of the Nano-Hyperspec® camera are a compact 76.2 mm x 76.2 mm x 119.4 mm, and it weighs a mere 520 g without its lens. The sensor collects optical data on 640 spatial and 270 spectral bands. The camera has an extraordinarily wide field of vision, enabling the coverage of a maximized area and the creation of in-flight images that are razor sharp, even at the edges. The huge memory – 480 GB – means that approx. 130 minutes worth of images can be recorded at a rate of 100 frames per second (fps).
The frame speed has been adapted to the airspeed of the AibotX6. It is possible to mount a GPS (Global Positioning System) with an IMU (Integrated Measurement Unit) directly on the sensor for automatic georeferencing of images. Another new solution is High Precision GNSS (Global Navigation Satellite System), which was designed and built in collaboration with development engineers from the entire HEXAGON Group especially for the AibotX6, offers a new, significantly higher level of positional data precision and can be used as a supplementary enhancement to meet corresponding requirements in the high-precision field. The Nano-Hyperspec® camera is supplied along with the AibotX6 and its control software Aibotix AiProFlight, including a special version of the user software Hyperspec III that controls sensor operation, photography and sensor performance during the flight, as well as processing incoming GPS/IMU data, LiDAR data (light detection and ranging) and spectral data to fully integrated data cubes.
