Geo-Pointing is a capability that enables any FLIR MCS pan-tilt unit to be commanded using latitude, longitude, and altitude coordinates (geo-coordinates or GPS coordinates). All E-series pan-tilts (PTU-D300E, PTU-D100E, PTU-D48E, PTU-E46) include the geo-pointing module — no external hardware is required for these models.
PTU-D300-RF and PTU-D47 models do not include GPM in their base configuration, however this capability can be supplemented with the external “PTU-DGPM” module as described below. Legacy D-Series PTU models (PTU-D300, PTU-D100, PTU-D48, and PTU-D46) can also use the PTU-DGPM to enable Geo Pointing.
Once configured, it the PTU accepts geo-coordinates over the built-in Ethernet/IP interface and automatically commands the pan-tilt to aim at the corresponding location. This is a powerful capability that greatly simplifies systems integration and allows efficient coordination of multiple sensors and systems. Several cameras/sensors can be easily commanded to look at a single position by simply sending the same GPS command to all pan-tilt units. With geo-pointing, pan-tilts can be controlled from any geo-spatial or map-based user interface (e.g., Google Earth).
- Automatic pointing with GPS coordinates
- Simplifies System Integration (slew-to-queue, radar, telemetry)
- General Ethernet/IP interface to any pan-tilt
All E-series pan-tilt models (PTU-D48E, PTU-D100E, PTU-D300E) come equipped with the geo-pointing module built-in, no external hardware required. PTU-D46 and PTU-D47 models are supported with the external “PTU-DGPM” module.
Geo-pointing allows applications to point cameras, lasers, and other devices, using Latitude/Longitude coordinates instead of pan-tilt angles. Geo-pointing is a built-in feature on E Series models (PTU-D48E, PTU-D100E, PTU-D300E) and available as an external module (PTU-DGPM) for PTU-D46/PTU-D47 models.
Streams of target geo-coordinates can be sent to the pan-tilt unit allowing tracking/following of targets to keep them in the field-of-view. Geo-pointing control greatly simplifies system integration and improves system modularity and performance. New geo-pointing-equipped pan-tilt units can be added to the system with little or no change to system logic. Peripheral sensors, such as ground radar, can directly command camera systems to focus on a target of interest. A stream of Geo-positions can be sent to the pan-tilt to track an object of interest. Built-in web-pages allow for simple setup and configuration. An interactive landmark-based calibration utility is used to compute the Pan-Tilt's own position.
Commands are accepted over the built-in Ethernet/IP or Serial interfaces to control or configure the geo-pointing module (Ethernet only for the PTU-DGPM).
The geo-pointing module must be configured with the position of the pan-tilt unit in geo-coordinates (latitude, longitude, altitude, and 3D orientation). The latitude, longitude and altitude of the pan-tilt unit are entered manually using the GPM/pan-tilt web interface (e.g., using a hand-held GPS unit to measure the installed pan-tilt unit position).
The built-in calibration function computes the orientation of the pan-tilt in real-world coordinates using a set of user-provided landmarks. Landmark locations (lat, lon, alt) are entered through the web interface. The pan-tilt is then aimed at four or more landmarks and the system updates the pan-tilt's position estimate.
Once calibrated, the system can accept Geo-pointing commands and queries.
The geo-pointing module has a built-in web server and web pages allowing the user to:
- Configure and Control the Pan-Tilt Unit
- Configure and Calibrate Geo-Pointing Module
- Manually Enter Geo-Pointing Commands
