Sensor Fusion for Precision Agriculture

Low-cost Lidar Camera System without GNSS
Precision agriculture has considerably benefited from the use of unmanned aerial vehicles, often combined with active ranging sensors like Lidar to gather information from underneath the crops, but existing systems are relatively expensive for the farming sector. In this project, researchers in Canada have used an integrated sensor orientation method for the local referencing of Lidar measurements. Their approach is based on loosely coupled, image-aided inertial navigation in which the pose of the camera replaces the GNSS measurements. The result is a low-cost solution that is useful for capturing topographic data of inaccessible areas as well as in GNSS-denied environments.... (read more)

Mapping a University Campus in Brazil

Creating Indoor and Outdoor Maps for a Routing Application
A pilot project conducted at a university campus in Curitiba, Brazil, aimed to create outdoor maps using UAS photogrammetry as well as indoor floor plans. At universities, facility managers and other support staff need easy access to data, including geodata, for maintenance, safety measures or routing of students, staff and visitors. A responsive geodatabase containing detailed and up-to-date information on roads, the interior and exterior of buildings and other objects is a key tool in that context. The authors of this article describe a pilot project conducted at a university campus in Curitiba, Brazil, aimed at creating outdoor maps using... (read more)

New INS/GNSS Solution to Increase Productivity of UAV-based Surveying

SBG Systems will present for the first time at AUVSI’s Xponential show in Chicago, USA, the Quanta UAV Series, a new line of inertial navigation systems (INS) dedicated to UAV-based surveying integrators. As SBG Systems aims to give UAV surveyors more autonomy for additional survey lines, the company has designed a small and low-power inertial navigation system offered on two levels of accuracy. Quanta UAV and Quanta UAV Extra have been developed for compact Lidar to high-end beyond-visual-line-of-sight (BVLOS) mapping solutions. Both solutions provide precise orientation and centimeter level position data delivered both in real-time and post-processing. This direct geo-referencing solution eliminates... (read more)

Catching up on Photogrammetry and Laser Scanning

An Impression of the Oldenburger 3D-Tage Event
In the German geospatial industry, there is a longstanding platform for open and constructive dialogue with researchers but also informal talks and discussion in between. It is called the Oldenburger 3D-Tage and is held annually at the Jade University of Applied Sciences in the northern German city of Oldenburg. This article provides a round-up of the 18th edition of the event which took place in February this year and offered delegates an inspiring update on the latest developments in all aspects of 3D mapping, both photogrammetry and laser scanning. The 3D-Tage programme is pretty straightforward: two full days of sessions... (read more)

Bridging the Gap between Aerial Imaging and Terrestrial Data Capture

The Challenges of Drone Use in Facade Mapping
There have been rapid advancements in unmanned aerial systems over recent years, yet there is widespread consensus that we have still only seen a fraction of how unmanned aerial vehicles (UAVs or ‘drones’) could ultimately improve efficiency for geospatial professionals and their customers. To get a glimpse of the future, 'GIM International' spoke to Mark Nicolai, co-founder of industry start-up Aeroscan. Here, he shares his vision of how drones could form the missing link between aerial imaging and terrestrial data capture. According to independent research by the likes of PwC and Goldman Sachs, the construction industry tops the list in... (read more)

Sony Camera Payload for DJI Drones from Klau Geomatics

With the end of the DJI X4s camera, drone operators have been looking for a quality mapping camera solution for the Inspire 2 and M200/M210/M210V2 drones. Klau Geomatics has released a Sony camera/PPK payload to offer better results from these drones. This enables more effective and accurate mapping and inspection using superior-quality, plug-and-play camera payloads with precise 3D positioning accuracy. Sony has a number of quality cameras, proven to generate high-quality mapping from drones. Models such as the RX1r2, a6300 and a5100 all have large sensor, leaf shutters and no moving internals to affect camera calibration. An RX1r2 will cover... (read more)

Recent Developments in Close-range Photogrammetry

A Measurement Technology in Transition
Dramatic advances in automatic digital image analysis have opened up new applications and made photogrammetry applicable for a broader field of users that lack specific knowledge of photogrammetry. Megatrends such as Industry 4.0, building information modelling (BIM) and the digital transformation are driving the advancement of 3D measurement technologies, both in terms of high-end systems and low-cost sensors. New technical challenges such as autonomous driving or unmanned aerial vehicles are demanding innovative sensor systems, but also extended maps and models of the environment. Modern approaches such as structure from motion (SfM), simultaneous localization and mapping (SLAM) or visual odometry are... (read more)
