First UAV Flight from Unmanned Boat

The newest aircraft carrier does not have acres of flight deck. In fact, it has no deck at all. Rather than carrying a crew of thousands, it sails without a soul on board. Yet the aircraft that it operates can fly much longer and further than anything based on a fleet leviathan. That aircraft is Aerovel’s 20kg Flexrotor, which combines VTOL and a small footprint with a Hawaii-to-West Coast range. The carrier is a 4-metre skiff equipped to launch, retrieve and service the Flexrotor automatically. In what are believed to be the first-ever flight cycles of an unmanned aircraft based...

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)

Riegl and Applanix Integrate on UAV

RIEGL Laser Measurement Systems and Applanix Corporation have announced that the Applanix AP50 GNSS-Inertial sensor system has been successfully integrated with RIEGL’s VQ-820-GU topo-bathymetric airborne laser scanner on board the Schiebel CAMCOPTER S-100 UAV. The RIEGL VQ-820-GU is specifically designed to survey sea beds, rivers or lakes and is well suited for combined ground and hydrographic airborne survey. The Applanix AP50 GNSS-Inertial system is a GNSS-Inertial sensor plus Inertial Measurement Unit (IMU) in a compact form factor. It features a high performance precision GNSS receiver and the Applanix IN-Fusion GNSS-Inertial integration technology running on a powerful, dedicated Inertial Engine (IE)... (read more)

Hydrographic Airborne Scanner Integrated in UAV

Schiebel and RIEGL Laser Measurement Systems, Austria, have successfully integrated the Schiebel CAMCOPTER S-100 Unmanned Air System (UAS) together with the RIEGL VQ-820-GU Hydrographic Airborne Sensor. The integration marks the first time that this new airborne sensor was flown on board of a UAV. The S-100 helicopter UAS carried a special Schiebel-made composite pod containing the sensor, the IMU-GNSS unit, the data recording and transfer unit as well as a digital camera, during the flight tests in Grossmittel, Austria, which were carried out this month. This fully integrated system thus enables acquisition of high-accuracy hydrographic and topographic data, even in... (read more)

UAV Overcomes Position Challenges near the North Pole

Engineers on board the Alfred Wegener Institute’s research icebreaker Polarstern have programmed an unmanned autonomous vehicle (UAV), allowing it to navigate despite the deviations produced by the Earth’s magnetic field near the North Pole. The researchers recently celebrated the multicopter's first successful autonomous flight and landing on an ice floe. According to Sascha Lehmenhecker, an engineer at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI, Germany), experienced that flying on high latitudes, autonomous navigation is a major challenge. Navigation systems normally use magnetic sensors. Near the poles, the lines of the Earth’s magnetic field are nearly... (read more)

Optech at MAPPS 2014 Summer Conference

Optech, Canada, is the official sponsor for the MAPPS Golf Tournament at the MAPPS 2014 Summer Conference, to be held from 27 to 31 July 2014 in Coeur d’Alene, Idaho, USA. This year’s Golf Tournament is taking place on Wednesday, 30 July at the scenic Coeur d’Alene Golf Course, known for its unusual 'floating' green on the 14th hole in the middle of the lake. During the conference, Optech president Max Elbaz will join a panel to discuss the many applications of bathymetric/topographic Lidar systems and data (from 11:00 a.m. to 12:00 p.m. on Tuesday 29 July). Foremost among these... (read more)
