UAV Capable of Capturing Oblique Imagery

senseFly’s drones eBee and swinglet CAM, both designed for mapping missions, are capable of capturing oblique images quickly to complement a mapping project or to add additional documentation. This patent-pending technology is based on a propriatary control algorithm that takes oblique images of photo targets without the need for a camera gimbal, enabling senseFly’s ultralight mapping drones to take aerial shots with up to 45° inclination from the photo target. The algorithms running on board the drone’s autopilot automatically place and orient the drone based on the defined image resolution and inclination (0-45°) selected by the operator. The drone then... (read more)

Bathymetry from UAV Imagery and Machine Learning

Improving Results with Refraction Corrections
Accurate bathymetric mapping of shallow areas is essential for a plethora of offshore activities. Through Structure from Motion (SfM) and Multiview Stereo (MVS) techniques, images can provide a low-cost alternative compared to Lidar and sonar systems while also offering important visual information. This article presents a new framework for mapping the seabed in clear and calm shallow waters for small- and large-scale surveys using aerial imagery and machine learning to correct the geometric effects of refraction on the 3D point clouds and the imagery. SfM is a photogrammetric technique for estimating 3D structures from 2D image sequences. It involves acquiring... (read more)

Atmos UAV Integrates Thermal, Multispectral and High-resolution Imagery

Atmos UAV, a drone manufacturer for mapping and surveying from Delft, the Netherlands, continues to expand its payload options. The most recent addition is the new MicaSense sensor, Altum, which integrates a radiometric thermal camera with five high-resolution narrow bands. This produces advanced thermal, multispectral and high-resolution imagery in one flight for advanced analytics purposes. Marlyn, the fixed-wing VTOL surveying platform developed by Atmos UAV, is now the only unmanned aerial vehicle (UAV or 'drone') in its class capable of carrying this new high-end sensor. With this integration, Atmos team wanted to offer professionals a tool that maximizes their surveying... (read more)

EnsoMOSAIC UAV

The most new activity in remote sensing is at the moment found in the UAV and UAS sector (Unmanned Aerial Vehicle / System). There are hundreds of companies, institutions and individuals constructing UAVs for various uses and objectives. Both fixed wing and helicopter -based approaches are popular.       To serve manufacturers and operators of UAVs Stora Enso has released new versions EnsoMOSAIC UAV and EnsoMOSAIC UAV Pro of its leading EnsoMOSAIC automatic small and medium format image processing software. The new versions have full functionality and image rectification power, and are scaled for typical imaging project sizes of... (read more)

What is a UAV?

Unmanned Aerial Vehicles come in different forms (fixed-wing, copter, hybrid) and for many purposes and require different skills. Re-usable aircraft flown without onboard human crew have been in existence since 1916, the bulk of applications concerning reconnaissance and other military missions too shady, dirty or dodgy for human lives to be jeopardised. Ongoing miniaturisation of electronics is enabling smaller and smaller Unmanned Aerial Vehicles (UAV), and these are increasingly equipped with cameras or other sensors to support aerial geo-data collection. UAVs appear in manifestations as diverse as aeroplanes and helicopters of all sizes and shapes, motorised para-gliders, blimps, kites and balloons. What sort of UAV is suitable as a platform for digital cameras and other remote sensors? The... (read more)

Rwanda Pioneers UAV Mapping

After Rwanda made waves in the news early last year for allegedly being the first country to approve drone-based deliveries, people started paying attention. The country, with its rolling hills and one of the fastest-growing economies in Central Africa, has already established regulations regarding drones and become a vanguard of sorts for the region. To support this development, in 2016 the University of Twente organised a course in Rwanda on the latest drone mapping techniques. There is a huge market in Africa at the moment, according to Francesco Nex, assistant professor at the ITC Faculty, University of Twente. The country is growing very fast, with... (read more)

A Truly Photogrammetric UAV

AviSystem/Taxus SI
The AviSystem UAV was made on the assumption that it was intended to be a photogrammetric system. Hence, when designing the AVI, it was created for long, stable, precise and efficient flying – photogrammetric flying. AVI right before take-off. The Polish company Taxus SI Ltd. embarked on the AviSystem project in 2009 with support from the European Regional Development Fund. Poland’s best specialists in the field of unmanned aircraft construction were invited to join the project. Design of the entire system, of which the main element is the AVI drone, was completed within two years. The AVI is an electrically... (read more)
