GCPs for Satellite Image Georeferencing Surveyed Worldwide with GNSS PPP

GNSS positioning by precise point positioning (PPP) has developed over the last few years and is frequently used by the scientific community. Its real-time or post-processing applications are already used in several fields (e.g. in farming for tractor guidance or in aerial survey for calculating flight paths), but despite this its use remains relatively low with surveyors, mainly due to the initialisation time. This method, however, can prove to be effective, particularly in regions where there are no or few permanent GNSS stations (CORS) to establish a geodetic survey traverse and fix ground control points (GCPs) for aerial or satellite...

Accurate Georeferencing for UAV Surveying without Base Station

Klau Geomatics, specialised in post processed kinematic (PPK) direct georeferencing technology, has announced its new No-Base-Station high-accuracy georeferencing solution for unmanned aerial vehicles (UAVs). This innovative new solution is the result of close collaboration between Klau Geomatics and Hexagon’s Geosystems Division, enabling users to conduct UAV surveying projects without running a local GPS receiver, producing high-accuracy 3D survey data. In addition to accuracy, which is the most important feature of our georeferencing solution, is the simplified and efficient workflow. Users don’t need any survey equipment to place Ground Control Points (GCPs) or even a local base station for their PPK. They can... (read more)

Applanix and Think 3D Deliver UAV Lidar Mapping with Direct Georeferencing

Historically, Lidar-based aerial surveys were impractical for all but the very largest UAVs due to the size and power constraints. Recently, however, Applanix and Think 3D have joined forces to make airborne Lidar scans from small drones not only possible, but also practical, cost effective and highly accurate. Applanix has developed a small, lightweight and low powered DG (Direct Georeferencing) solution and applied it to Think 3D’s Stormbee multicopter, integrated with Trimble’s AP15, to make it possible and deliver maximum efficiency, accuracy and performance for Lidar surveys from any unmanned vehicle. Integrated Solution The Stormbee is a directly georeferenced UAV Lidar... (read more)

Integrating UAV-based Lidar and Photogrammetry

Dense 3D Point Cloud Generation with Ultra-high Precision
Recent unmanned aerial vehicle (UAV or ‘drone’) platforms jointly collect imagery and Lidar data. Their combined evaluation potentially generates 3D point clouds at accuracies and resolutions of some millimetres, so far limited to terrestrial data capture. This article outlines a project that integrates photogrammetric bundle block adjustment with direct georeferencing of Lidar point clouds to improve the respective accuracy by an order of magnitude. Further benefits of combined processing result from adding Lidar range measurement to multi-view-stereo (MVS) image matching during the generation of high-precision dense 3D point clouds. The project was aimed at the area-covering monitoring of potential subsidence... (read more)

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)
