2、an-tilt units. It allows applications to point cameras, antennas, lasers, and other devices, using Latitude/Longitude coordinates in addition to pan-tilt angles. The GPM is a multi-function device that provides: 1. new pan-tilt commands to allow geo-pointing,2. Ethernet/IP interface for geo-pointing
3、 and standard pan-tiltcommands, and3. a set of web pages for graphical configuration and controlGeo-coordinates of targets of interest are sent directly to the GPM-equipped Pan-Tilt Unit, and the unit is automatically aimed at that geo-coordinate. Streams of target coordinates can be sent to the uni
4、t allowing tracking/following of targets to keep them in the field-of-view. The Geo-Pointing Module accepts both geo-pointing and standard pan-tilt commands over TCP/IP using the built-in Ethernet port and is compatible with all Directed Perception pan-tilt units.The GPM greatly simplifies system in
5、tegration and improves system modularity and performance. New GPM-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
6、 be sent to the GPM to track an object of interest. Applications can communicate with the GPM over Ethernet (TCP/IP) eliminating the restrictions of serial connections. A built-in web-page interface allows for simple setup and configuration. An interactive landmark-based calibration utility is used
7、to compute the Pan-Tilts own position. Alternatively, GPS/orientation sensors can be integrated to automate calibration.Key features include:Support for both traditional and Geo-coordinate commandsSimple configuration using built-in web pagesStreaming commands allow tracking a moving targetApplicati

The GPM connects to the Pan-tilt unit (PTU) Host Interface (RS-485). Both standard pan-tilt pointing and configuration commands, as well as Geo-pointing
14、commands can be sent to the GPM. Standard pan and tilt commands are passed directly on to the PTU. Geo-pointing commands are processed by the GPM to compute pan-tilt angle commands which are then issued to the attached PTU.The GPM must be configured with the position of the pan-tilt unit in geo-coor
15、dinates (latitude, longitude, altitude, and 3D orientation). The latitude, longitude and altitude of the pan-tilt unit are entered manually using the GPMs 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
16、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-tilts position estimate.Once calibrated, the GPM
17、 can accept Geo-pointing commands and queries.Web InterfaceThe GPM has a built-in web server and web pages allowing the user to:Configure and Control the Pan-Tilt UnitConfigure and Calibrate the Geo-Pointing ModuleManually Enter Geo-Pointing CommandsSystem AccuracyOverall accuracy of the Geo-pointin
18、g commands depends on the pointing resolution of the PTU and accuracy of the initially provided geo-position and orientation of the PTU. For target standoff distances of greater than 1000m, angular error of the Geo-pointing will approximately equal error in the pan-tilt orientation. By using several
19、 well-spaced landmarks, and careful aiming during calibration, angular accuracy of Geo-pointing can approach the angular resolution of the PTU being used.TargetField of View (angle)Pan Tilt UnitError (angle)Connections & CommunicationsEthernet RJ45 (10/100baseT)Pan-Tilt RS-485 Host InterfaceMechanic
