Reliability of direct georeferencing : A case study on practical problems and solutions : Final Report on Phase 2
This report studies a practical problem related to the use of GPS/INS technology for sensor direct georeferencing. It is a case study of a specific, yet typical, situation where the performance of a GPS/INS was pronounced unsatisfactory for orientation of an airborne sensor. However, it was in fact not the poor quality of the navigation data but rather numerous disregards occurring in the fligh...
متن کاملOn Improving Navigation Accuracy of GPS/INS Systems
Direct georeferencing, also referred to as direct platform orientation (DPO), is defined as direct measurement of the imaging sensor external orientation parameters (EOP), using positioning and orientation sensors, such as the Global Positioning System (GPS) and Inertial Navigation System (INS) or Inertial Measurement Unit (IMU). Imaging sensors, most frequently supported by the DPO technique, ...
متن کاملDirect Georeferencing of Tls in Surveying of Complex Sites
The high powerfulness of TLS technique for quick 3D data acquisition is extending its use to many fields. To further reduce the surveying time and to simplify all operational tasks, the TLS direct georeferencing may be a very suitable approach instead of the technique based on ground control points (targets). This chance is allowed by the most part of existing instruments, as a default or as an...
متن کاملThe OEEPE Test on Integrated Sensor Orientation – Results of Phase I
The European Organisation for Experimental Photogrammetric Research (OEEPE) has embarked on a test investigating integrated sensor orientation using GPS and IMU in comparison and in combination with aerial triangulation. The test consists of two phases. The first phase comprises the system calibration and the determination of the exterior orientation parameters. The second phase deals with the ...
متن کاملFully Automatic Feature-based Registration of Mobile Mapping and Aerial Nadir Images for Enabling the Adjustment of Mobile Platform Locations in Gnss-denied Urban Environments
Mobile Mapping (MM) has gained significant importance in the realm of high-resolution data acquisition techniques. MM is able to record georeferenced street-level data in a continuous (laser scanners) and/or discrete (cameras) fashion. MM’s georeferencing relies on a conjunction of Global Navigation Satellite Systems (GNSS), Inertial Measurement Units (IMU) and optionally on odometry sensors. W...
