The 3D ImageVector allows for the measurement of image center positions in terrestrial photogrammetry. You obtain ”direct georeferencing” for surveying, using terrestrial or aerial photogrammetry. There is no need for ground control points for georeferencing! The 3D ImageVector is commonly used in the following sectors: surveying, infrastructure, architecture, archaeology, UAV pilots, etc.
The 3D ImageVector records the GNSS RINEX data (or corrected GNSS position data) and the solid angle determination via IMU. Trigger information with a resolution of 30 ns (nanoseconds) is recorded for each image. The 3D ImageVector comes in two models with different position accuracy. The 3D ImageVector -Mono- achieves a position accuracy of 8cm (PPK, depending on the reception), while the 3D ImageVector -Multi- has an accuracy of 2cm. Angles are measured by the 3D ImagVector’s onboard IMU to an accuracy of 1 °.
3D ImageVector – MONO –
The -Mono- contains a ublox NeoM8P/T GNSS chip, which achieves a position accuracy of 8cm with fixed solution or 40cm with float (depending on receiver). The Helix antenna provides better reception, even with a camera tilted to 45 °. It also includes a modern 9x Axis MEMS IMU with quaternion roughness and an anti-drift filter algorithm. The Connection to the camera is done via ISO hot shoe.
3D ImageVector – MULTI –
The -Multi- contains a ublox ZED-F9P GNSS module, which achieves a position accuracy of 2cm with fixed solution or 40cm with float (depending on receiver). It also includes a modern 9x Axis MEMS IMU with quaternion roughness and an anti-drift filter algorithm. The Connection to the camera is done via ISO hot shoe.
The logger has an autonomous power supply of approx. 4h during normal operation. The LEDs signal the quality of the reception. To reset the data, a new logfile button is attached.
Positions measured by the 3D ImageVector can be measured either in real time (RTK) or in post processind (PPK). For this, RINEX data from an external source is needed, either from a correction data service (EPOSA, APOS, SAPOS, SWISSPOS, etc.) or form a GNSS base station that can record RINEX data for the appropropriate channels (L1 for -Mono- or L1/L2 for -Multi-). RTK corrections are only available from a correction data service and require an android mobile device to connect to the ImageVector via Bluetooth.
The REDToolbox is included in the purchase of a 3D ImageVector. The REDToolbox is a geotagging software for combining the ImageVector logfile with the image data. The software performs a validity check of the GNSS signal and quality output. It is easy to use and calculates with robust algorithms. The following outputs are available from REDtoolbox: Google Earth KML Output, Raw Data Output, AgiSoft Metashape project file, Pix4D project file, Reality Capture text file output and 3D Survey text file output. The REDToolbox is compatible with Win7, Win10 x64 / x32.
The following products are included in the purchase of the 3D ImageVector: camera add-on, data logger, charger, USB data cable and the software REDtoolbox.
