A navigation planning method and device 101 comprising a chart data receipt unit 119, a waypoint receipt unit 121, a potential waypoint receipt unit 123 configured to receive a potential waypoint 204, and a position specifying unit 125 configured to: determine a position of the potential waypoint 204 by: receive a current position data of the potential waypoint 204, receive position information of the plurality of targets 206a, 206b, calculate a distance between the potential waypoint 204 and each of the plurality of targets 206a, 206b, calculate an angle 506 between a first bar 208 and a second bar 210 on a chart, where the first bar 208 is to connect the latest waypoint 202 with the potential waypoint 204 and the second bar 210 is to connect the potential waypoint 204 with the plurality of targets 206a, 206b, and output an activating signal when the calculated angle 506 is equal to a threshold value and when the calculated distance is at minimum.

Even in a case where positioning precision of positioning using a GPS signal or output data of an internal sensor is low, a location is precisely estimated. For example, a location of a moving object is estimated based on a relative locational relationship between at least two landmarks or at least two transmitters and the moving object. The location of the moving object may also be estimated based on a relative locational relationship between at least two parts of a single landmark and the moving object. The location of the moving object may also be estimated based on a relative locational relationship between a single transmitter that has output two signals and the moving object. The location of the moving object may also be estimated based on a relative locational relationship between each of at least one landmark and at least one transmitter, and the moving object.

A system and method for storing and communicating the location of the pin on one or more greens on a golf course. The location of the golf pin is entered into a system and is uploaded for incorporation in a course map depicting the golf course being played by the golfer. The pin location information is used to measure distance from the location aware device to the pin location.

L'invention concerne un système de trajectographie de bâtiment naval. Il comporte sur le bâtiment (10) un émetteur (11) de rayonnements magnétiques et, disposés au fond de la mer, deux magnétomètres triaxiaux (12 et 13). Ce système permet notamment d'établir, dans une station d'immunisation, le trajet d'un bateau immunisé ou à immuniser contre les détections magnétiques.
摘要:
Pairs of images are presented to an observer under conditions such that they are perceived as a single image and provide information about their mutual relationship. The pair are derived from non-equivalent image means (208, 210), e.g. from (a) a photograph (226) of a scene subject to change and (b) direct viewing (208) of the changed scene. They are generally presented simultaneously to respective eyes. Intermittent alternate occlusion (230) of the images highlights differences. The image pairs may constitute movie or television (T, t) displays to provide 3-dimensional effects.
摘要:
Ein Navigationsrechner (12) liefert die Position eines Fahrzeuges in Gitterkoordinaten. Diese Position wird durch einen in zwei Koordinaten steuerbaren Lichtsender (122) auf einem Kartenblatt angezeigt, das in einer Kartenaufnahme (40) des Positionsanzeigegerätes (36) gehaltert ist. Kartendaten der verfügbaren Kartenblätter sind in einem Speicher gespeichert. Ein Mikrokomputer steuert den Lichtsender (122). Wenn der Lichtsender (122) den Rand des Kartenblatts erreicht wird ein Randsignal erzeugt. Der Mikrokomputer prüft dann anhand der gespeicherten Kartendaten, ob die vom Navigationsrechner (12) gelieferten Gitterkoordinaten auf einem der vorhandenen Kartenblätter anzeigbar sind. Ist dies der Fall, wird die Kennzeichnung des Kartenblatts auf einem Anzeigefeld (44) angezeigt und der Lichtsender (127) in die Stellung verfahren, die in dem neuen Kartenblatt den Gitterkoordinaten der Fahrzeugposition entspricht. Anderenfalls erfolgt eine Fehlanzeige.
摘要:
Operating an autonomous grounds maintenance machine includes determining a travel path for the machine to reach a destination waypoint in a zone of a work region. The travel path is analyzed for problem areas based on a predetermined terrain map. Rotations of the machine may be planned even before the machine begins to travel down the path to proactively prevent the machine from becoming trapped.
