![]() ![]() Just one lens is needed resulting in precisely co-registered spectral channels with overlapping spectral sensitivities (Figure 1). The Canon multispectral cameras are equipped with modified Bayer colour filters – instead of recording blue, green and red, the green (G), red (R) and near infrared (NIR) bands are captured. The Canon S110 RGB is a low-cost colour camera, the Canon S110 NIR and S110 RE are low-cost multispectral cameras while the multiSPEC 4C is a high-end system. The eBee family is marketed in conjunction with customised sensors which can be controlled by the autopilot of the fixed-wing UAV. The lightweight fixed-wing eBee can be operated fully autonomously, requires hardly any piloting skills and is ideal for covering larger areas. This study tested the Canon S110 NIR and a prototype version of the multiSPEC 4C, both of which are multispectral cameras, as well as the thermoMAP, a TIR sensor. Focusing on precision farming, Airinov modifies Canon cameras into multispectral sensors and manufactures the multiSPEC 4C multispectral camera and the thermoMAP thermal infrared sensor. Based in Cheseaux-Lausanne, Switzerland, and founded in 2009, senseFly manufactures fixe-wing UAVs and equips them with customised lightweight cameras developed by Airinov, which is based in Paris, France. The multispectral cameras and thermal infrared (TIR) sensor in the authors’ performance tests were mounted on an eBee from senseFly.

Nowadays, however, lightweight multispectral and thermal sensors on small UAVs are commercially available. In contrast, multispectral and thermal sensors were until recently too heavy and bulky for small UAV platforms, even though their potential was demonstrated almost a decade ago. (The maps this software generates can also be imported into third-party farm management software for further analysis and to optimise treatment prescriptions before exporting these to other precision agriculture equipment.Mini and micro unmanned aerial vehicles (UAVs) in combination with cost-efficient and lightweight RGB cameras have become a standard tool for photogrammetric tasks. These images are transformed into high-resolution orthomosaics (2D maps) by the eBee Ag’s supplied image processing software, which features an index computation tab for calculating NDVI and other indicators – to show which crops require treatment or closer examination. The eBee Ag is a mini mapping drone that can c ollect aerial photography of up to 2,470 ac (1,000 ha) in a single automated flight. We look forward to contributing our insight and experience to the Precision Ag Council so that this group can help farmers do more of what matters: accurately assess and manage their crops increase yields and grow their businesses.” Joining AgGateway is now the next logical step. “We then achieved a new level of integration with the arrival of the multiSPEC 4C camera, which was co-developed with agronomy specialists Airinov and the French National Institute for Agricultural Research (INRA). “ With the launch of our eBee Ag this summer we took a great first step towards meeting the scouting requirements of farmers and crop consultants,” says Jean-Christophe Zufferey, CEO of senseFly. The invaluable market feedback that AgGateway membership provides will also help senseFly further optimise its technology to match the evolving needs of the industry. This will allow the company to collaborate closely with other council members to help define appropriate standards, guidelines and implementation protocols, which will, in turn, improve the integration of UAV data into the precision agriculture workflow. ![]() Īs an official AgGateway member, senseFly has already joined AgGateway’s Precision Ag Council. Swiss mini drone producer senseFly has joined AgGateway, becoming the first UAV manufacturer to join this non-profit consortium of businesses that serve the agriculture industry. Cheseaux-Lausanne, Switzerland, Septem– Swiss mini drone producer, senseFly, has become the first UAV manufacturer to join AgGateway. ![]()
