3D IMAGE VECTOR
GNSS & IMU Camera Add-on
The technology is comprised of a GNSS receiver and an IMU, which are built into a camera attachment and connect via the hot shoe of your camera. This information can be used for short-range photogrammetry applications to perform direct georeferencing with centimeter accuracy. Save time and speed up your process by eliminating the need for control points (GCPs) in many applications. You can also perform image documentation of man-made and natural assets and infrastructure, while recording the exact shooting positions and directions.
Examples of industries where the 3D ImageVector is commonly used include the following:
- Monitoring and documentation of infrastructure
- Natural hazard documentation and assessment
A light-weight modular version of the 3D ImageVector, our UAV upgrade kit, is also available for drone photogrammetry applications.
The 3D ImageVector enables the recording and calculation of image centers in terrestrial photogrammetry. You get direct georeferenced data for surveying when using terrestrial or UAV photogrammetry. This means there are no ground countrol points (GCPs) required for georeferencing! The 3D ImageVector is used for the following industries: surveying, infrastructure, natural hazards, geology, mining, construction, architecture, archeology, etc.
The 3D ImageVector records the GNSS RINEX data or corrected GNSS position data and orientation in the form of yaw, pitch and roll. Trigger information is recorded for each image at a resolution of 30 nanoseconds. Depending on the version, the 3D ImageVector achieves a position accuracy of up to 2 cm (reception-dependent using postprocessing) and an angle measurement repeatability of 0.5 °.
The 3D ImageVector – MULTI – contains a modern ublox ZED9F GNSS chip: GPS, GLONASS, BeiDou, Galileo L1, L2, L5 with a position accuracy of up to 0.02m + 1ppm (fixed) and 0.3m + 1ppm (float). The active helix antenna ensures better reception even in difficult environments. The 3D ImageVector – MULTI – also includes a modern 9x Axis MEMS IMU with quaternion rough angle and anti-drift filter algorithm. Connection to the camera is via ISO hot shoe.
The 3D ImageVector – MONO – contains a modern ublox NeoM8P / T GNSS chip: GPS L1 C / A, GLONASS L10F, with a position accuracy of up to 0.1m + 1ppm (fixed) and 0.5m + 1ppm (float). A Helix antenna provides reception, even with a camera tilted to 45 °. The 3D ImageVector – MONO – also includes a modern 9x Axis MEMS IMU with quaternion roughness and anti-drift filter algorithm. Connection to the camera via ISO hot shoe.
PPK: In order to correct the position data in postprocessing, RINEX data from an external source is needed. This data can be obtained from correction data services (EPOSA, APOS, SAPOS, SWISSPOS, etc.), the REDcatch base station (PC version or StandAlone ), or another GNSS receiver which supports the recording of RINEX data, such as the Emlid ReachRS, etc.
RTK: If a mobile network and an NTRIP client access is available, correction data can be sent to the 3D ImageVector via mobile phone. These are usually in RTCM 3.x format and are transmitted via Bluetooth.
The REDtoolbox is included in the purchase of our hardware products. The REDToolbox is geotagging software for combining the ImageVector logfile with the images. The software performs a validity check of the GNSS signal and output quality. It is easy to use and calculates with robust algorithms. The following output data formats are created: Google Earth KML, Raw Data text file, AgiSoft Metashape, Pix4D, Reality Capture and 3D Survey. The REDToolbox is compatible with Windows 7 and Windows 10 x64 / x32.
The following products are included in the purchase of the 3D ImageVector: camera attachment, data logger, charger, USB data cable and a full license for the REDtoolbox software.
