Description

Die Erfindung betrifft eine Golfplatzeinrichtung mit mindestens einem Zielfeld und einem von diesem beabstandeten Ersatzfeld.The invention relates to a golf course device with at least one target field and a replacement field spaced apart from it.

Beim Golf wird von einem Abschlagplatz einer Bahn ein Ball in Richtung eines zugeordneten entfernten Zielloches geschlagen. Im Regelfall landet der Ball beim ersten Schlag noch nicht im Zielloch, sondern in dessen näherer Umgebung, dem Zielfeld. Der Spieler begibt sich dann zu dem Zielfeld, um den Ball mit einem oder mehreren weiteren Schlägen ins Zielloch zu befördern. Eine Golfplatzanlage enthält eine Mehrzahl solcher Bahnen. Da Golfbälle mit großer Wucht geschlagen werden, müssen, wenn mehrere Bahnen von verschiedenen Spielern gleichzeitig bespielbar sein sollen, die Bahnen ausreichend räumlich voneinander getrennt sein, damit eine Gefährdung der Spieler durch fliegende Golfbälle weitgehend ausgeschlossen werden kann. Ein solcher Golfplatz beansprucht daher eine große Fläche.In golf, a tee is turned into a ball in the direction of a assigned to the distant target hole. As a rule, the ball lands the first shot, not in the target hole, but in the immediate vicinity, the target field. The player then goes to the target field to get the ball with one or more hits to the target hole. A The golf course complex contains a number of such courses. Because golf balls with big Strike must be struck when multiple tracks of different Players should be able to play at the same time, the tracks sufficiently spacious be separated from each other so that the player is endangered by flying Golf balls can be largely excluded. Such a golf course claims hence a large area.

Die Anlage eines Ersatzfeldes zu einem Zielfeld macht das Begehen der Spielbahn entbehrlich. Das Einlochen des Balls kann auf das dem Zielfeld in dessen spielwesentlichen Eigenschaffen nachgebildeten Ersatzfeld verlegt werden und die verschiedenen Bahnen können eng beieinanderliegen oder sich auch überschneiden. Das Ersatzfeld liegt vorzugsweise nahe beim Abschlagfeld. Spielwesentliche Eigenschaften des Zielfeldes und des nachgebildeten Ersatzfeldes sind insbesondere Art des Bodens und bei nichtebenen Zielfeldern deren Topographie. Weitere nachgebildete Eigenschaften können insbesondere Form und Größe des Zielfeldes sein.The creation of a replacement field to a target field makes walking the fairway dispensable. The ball can be punched in on the target field Substitute field, which is essential to the game, are relocated and the different tracks can be close together or overlap. The replacement field is preferably close to the tee box. Game essentials Properties of the target field and the simulated replacement field are in particular the type of soil and, in the case of non-level target fields, their topography. Further simulated properties can in particular shape and size of the target field.

Zur Fortsetzung des Spiels auf dem Ersatzfeld ist in einer zur Zielfeld-Position des ins Zielfeld geschlagenen Balls gleichwertigen Ersatzfeld-Position ein Ball auf dem Ersatzfeld zu positionieren, der dann in das Zielloch des Ersatzfeldes zu schlagen ist. Um insbesondere bei Wettbewerben einen der gebräuchlichen Spielweise weitgehend gleichwertigen Spielverlauf zu gewährleisten, soll die Reproduktion der relativen Ballposition vom Zielfeld im Ersatzfeld möglichst zuverlässig, aber auch mit vertretbarem Aufwand erfolgen.To continue the game on the replacement field is in a to target field position the ball of the equivalent substitute field position hit in the target field position on the replacement field, which is then in the target hole of the replacement field can be beaten. To be one of the most common, especially in competitions To ensure largely identical gameplay in gameplay, the Reproduction of the relative ball position from the target field in the replacement field if possible reliable, but also with reasonable effort.

Aufgabe der vorliegenden Erfindung ist es daher, eine Golfplatzeinrichtung anzugeben, welche eine solche zuverlässige Reproduktion der relativen Ballposition mit vertretbarem Aufwand ermöglicht.The object of the present invention is therefore to provide a golf course facility, which is such a reliable reproduction of the relative ball position enabled with reasonable effort.

Erfindungsgemäße Lösungen sind in den unabhängigen Patentansprüchen beschrieben. Die Unteransprüche enthalten vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung.Solutions according to the invention are in the independent patent claims described. The sub-claims contain advantageous refinements and Developments of the invention.

Die erfindungsgemäßen Lösungen betreffen die Situationen am Zielfeld bzw. am Ersatzfeld und sind sowohl einzeln als auch bevorzugt gemeinsam realisierbar.The solutions according to the invention relate to the situations in the target field or on the replacement field and can be implemented both individually and preferably together.

Zur Bestimmung der relativen Zielfeld-Ballposition wird vorteilhafterweise das Zielfeld mittels einer dort angeordneten Bildaufnahmeeinrichtung, die insbesondere eine Videokamera enthalten kann, überwacht und aus dem aufgenommenen Bild wird mittels einer Bildauswerteeinrichtung die relative Ballposition bestimmt. Anstelle einer Videokamera kann auch eine abtastende Bildaufnahmeeinrichtung, die in einer oder zwei Koordinatenrichtungen das Zielfeld nach Art eines Scanners überstreicht, vorgesehen sein. Die Bildaufnahmeeinrichtung kann auch mehrere Kameras oder Abtasteinrichtungen für verschiedene Teilbereiche eines größeren Zielfeldes enthalten.This is advantageously used to determine the relative target field ball position Target field by means of an image recording device arranged there, which in particular A video camera can contain, monitor and record from the The image becomes the relative ball position by means of an image evaluation device certainly. Instead of a video camera, a scanning image recording device, the target field in one or two coordinate directions scanned in the manner of a scanner. The image capture device can also have multiple cameras or scanners for different Contain partial areas of a larger target field.

Eine einfache Auswertung erfolgt auf der Basis eines vom Zielfeld zum Abschlag oder zum Ersatzfeld übertragenen Bilds von der Zielfeldsituation und rein visueller Reproduktion der Ballposition auf dem Ersatzfeld oder teilvisuell durch Ableiten relativer Positionskoordinaten aus dem dargestellten Bild, beispielsweise mittels einer in der Bildfläche verschiebbaren Markierung und Weiterverwendung solcher Positionskoordinaten.A simple evaluation is made on the basis of the target field to the tee or image transferred from the target field situation to the replacement field and purely visual reproduction of the ball position on the replacement field or partially visual by deriving relative position coordinates from the displayed image, for example by means of a marker which can be moved in the image area and Reuse of such position coordinates.

Bevorzugt erfolgt die Bildauswertung zur Bestimmung der relativen Ballposition aber automatisch, ohne daß der Benutzer hierfür tätig werden muß. Automatische Bildauswerteeinrichtungen sind an sich aus anderen technischen Bereichen wie beispielsweise der Verkehrsüberwachung bekannt und daher hier im Detail nicht beschrieben. Die in der vorliegenden Situation vorgesehenen Bildauswerteeinrichtungen können vergleichsweise einfach aufgebaut sein, da die Zielfeldsituation nur eine geringe Komplexität hinsichtlich der Auswertung aufweist.The image evaluation is preferably carried out to determine the relative ball position but automatically, without the user having to do anything. Automatic Image evaluation devices are in themselves from other technical areas as known for example from traffic surveillance and therefore here in Detail not described. The image evaluation devices provided in the present situation can be comparatively simple because the Target field situation shows only a slight complexity regarding the evaluation.

Der überwiegende Bildinhalt gibt das Zielfeld als solches wieder und ist im wesentlichen konstant und die relevanten Bildveränderungen bestehen im Hinzukommen eines neuen Balls. Vorteilhafterweise wird daher bei der Auswertung des durch die Aufnahmeeinrichtung gewonnenen Bildes ein Vergleich zeitlich nacheinanderliegender Bilder vorgenommen und lediglich eine Veränderung des Bildinhalts als neu hinzukommender Ball in Betracht gezogen. Eine weitere Prüfung, ob es sich bei der Bildveränderung um einen Ball oder ein anderes Objekt, beispielsweise ein Laubblatt oder einen Vogel handelt, kann vorteilhafterweise eine Analyse des Bewegungsverhaltens der Bildveränderung und/oder eine Auswertung der Farbinformation umfassen. Insbesondere die Farbinformation bietet ein einfaches Kriterium zur Unterscheidung verschiedener Objekte. Die Unterscheidungskraft kann noch verstärkt werden, indem das Ballmaterial zumindest oberflächlich ein mit natürlicher oder abgestimmt künstlicher Beleuchtung besonders signifikantes spektrales Reflexions- oder Absorptionsvermögen zeigt. Ein weiteres Kriterium zur Unterscheidung eines neu auf das Zielfeld treffenden Balls kann auch der zeitliche Zusammenhang mit einem Abschlag auf dieses Zielfeld sein.The predominant image content reflects the target field as such and is essentially constant and the relevant image changes consist in the addition of a new ball. It is therefore advantageous in the evaluation a temporal comparison of the image obtained by the recording device successive images made and only a change of the image content is considered as a new ball. Another Check whether the image change is a ball or another Object, for example a leaf or a bird, can advantageously be an analysis of the movement behavior of the image change and / or include an evaluation of the color information. especially the Color information provides a simple criterion for distinguishing between different ones Objects. The distinctive character can be strengthened by the Ball material at least superficially with natural or coordinated artificial Illumination particularly significant spectral reflectivity or absorption capacity shows. Another criterion for distinguishing a new balls hitting the target field can also be related to time a discount to this target field.

Die Aufnahmeeinrichtung ist vorzugsweise in mehr als 4 m Höhe über dem Zielfeld angeordnet, wodurch zum einen die Wahrscheinlichkeit, von einem Ball getroffen zu werden verringert wird und zum anderen zu große Positionsmeßfehler wegen zu flachem Beobachtungswinkel gegen die Zielfeldfläche oder eines Ausschnitts davon vermieden werden können.The receiving device is preferably at a height of more than 4 m above the Target field arranged, which on the one hand increases the probability of one Ball to be hit is reduced and on the other hand too large position measurement errors because the observation angle is too flat against the target field surface or part of it can be avoided.

Zur Vermeidung einer Bildfeldabschattung durch die Wimpelstange im Zielloch, durch deren Wimpel oder bei ausgeprägter Relief-Topographie des Zielfeldes können zwei oder mehr Bildaufnahmeelemente (Kamera, Scanner) an getrennten Positionen vorgesehen sein, die das Zielfeld aus unterschiedlichen Richtungen aufnehmen und deren Hauptblickrichtungen (mittlere Blickrichtungen) sich über dem Spielfeld kreuzen. Wenn sich die Bildfelder zweier Bildaufnahmeelemente überlappen oder im wesentlichen ganz überdecken, können auch die über zwei getrennte Bildaufnahmeelemente separat abgeleiteten relativen Ballposition auf Übereinstimmung verglichen werden. Bei Nichtübereinstimmung kann beispielsweise eine Dejustierung eines oder beider Bildaufnahmeelemte vorliegen und eine Neujustierung oder vorzugsweise eine Neukalibrierung notwendig sein. To avoid shadowing of the field of view due to the pennant pole in the target hole, through their pennants or with a pronounced relief topography of the target field can have two or more image acquisition elements (camera, scanner) on separate Positions can be provided that differentiate the target field Record directions and their main viewing directions (middle viewing directions) cross over the field. If the image fields of two image recording elements overlap or essentially cover completely also the relative ones derived separately from two separate image acquisition elements Ball position to be compared for agreement. If they do not match can, for example, a misalignment of one or both image recording elements are present and a readjustment or preferably a new calibration to be necessary.

Zur Kalibrierung der Bildaufnahmeeinrichtungen können vorteilhafterweise Referenzmarkierungen am Zielfeld im Überwachungsbereich der Überwachungseinrichtungen vorgesehen sein. Eine naheliegende Markierung kann durch das Zielloch gegeben sein. Zur genaueren Auswertung können zusätzliche weitere Referenzmarkierungen, die sich beispielsweise durch Farbe und/oder Form und/oder Reflexionsvermögen etc. ausreichend deutlich vom Hintergrund und anderen Objekten unterscheiden, vorgesehen sein. Die Bestimmung der relativen Ballposition erfolgt dann vorzugsweise nicht bezüglich der Bildmitte oder einer Hauptblickrichtung oder dgl., sondern lediglich bezüglich der Referenzmarken, deren Lage im Zielfeld sich bei einer Dejustierung eines Bildaufnahmeelements nicht ändert.To calibrate the image recording devices can advantageously Reference markings on the target field in the monitoring area of the monitoring devices be provided. An obvious marker can be given through the target hole. For more precise evaluation, additional further reference markings, which can be identified, for example, by color and / or shape and / or reflectivity etc. sufficiently clear from Differentiate background and other objects, be provided. The determination the relative ball position is then preferably not related the center of the picture or a main line of sight or the like, but only with respect of the reference marks whose position in the target field changes in the event of a misalignment of an image pickup element does not change.

Die genaue Reproduktion der relativen Ballposition auf dem Ersatzfeld wird erfindungsgemäß durch eine Projektionsvorrichtung am Ersatzfeld vorgenommen, welche eine Lichtmarke auf das Ersatzfeld projiziert, wobei die Position der Lichtmarke auf dem Ersatzfeld durch Steuern der Projektionsvorrichtung einstellbar ist. Die analogen oder digitalen Steuerwerte zur Steuerung der Projektionsvorrichtung können beispielsweise durch Tastatureingabe, durch Verschieben einer in einer Bildfläche verschiebbaren Markierung, wobei die Bildfläche vorzugsweise eine Darstellung der aktuellen Zielfeldsituation enthält, oder durch andere Bedieneinrichtungen vorgegeben werden. Vorzugsweise werden die Steuerwerte aber aus der Positionsinformation einer automatischen Bildauswertung der Zielfeldsituation abgeleitet und direkt oder nach Bestätigung durch einen Benutzer der Projektionsvorrichtung zugeleitet. Der Benutzer braucht lediglich einen Ball an die die Lichtmarke angezeigte Stelle zu legen, um das Spiel in präziser Reproduktion der Zielfeldsituation fortsetzen zu können. The exact reproduction of the relative ball position on the replacement field will made according to the invention by a projection device on the replacement field, which projects a light mark on the replacement field, the position the light mark on the replacement field by controlling the projection device is adjustable. The analog or digital control values for controlling the Projection device can, for example, by keyboard input Moving a marking which can be moved in an image area, the Image area preferably contains a representation of the current target field situation, or specified by other operating devices. Preferably but the control values are based on the position information of an automatic Image evaluation of the target field situation derived and directly or after confirmation fed to the projection device by a user. The user all you need to do is place a ball at the point indicated by the light mark, to continue the game in a precise reproduction of the target field situation.

Als Lichtquelle der Projektionsvorrichtung dient vorzugsweise eine über dem Ersatzfeld, insbesondere in mehr als 4 m Höhe angeordnete Lichtquelle mit enger Strahlbündelung und einstellbarer Strahlausrichtung. Die Lichtquelle kann beispielsweise eine Glühlampe mit stark bündelndem Reflektor oder einen Laser, der zur Augensicherheit auf unschädliche Leistungsdichte aufgeweitet sein sollte, umfassen.The light source of the projection device is preferably one above the Substitute field, in particular with a light source arranged at a height of more than 4 m narrow beam focusing and adjustable beam alignment. The light source can, for example, an incandescent lamp with a highly focused reflector or a Laser that expands to harmless power density for eye safety should be include.

Die Projektionsvorrichtung kann wiederum mehrere beabstandete Lichtquellen enthalten, deren beleuchtbare Bereiche unterschiedliche Abschnitte des Ersatzfeldes abdecken können, um Positionierfehler durch zu flachen Strahleinfall gegen die Oberfläche des Ersatzfeldes zu verringern. Die durch die zwei oder mehr Lichtquellen beleuchtbaren Bereiche können sich auch überlappen oder überdecken, wodurch Abschattungen vermieden oder, bei gleichzeitiger Markierung durch zwei Lichtquellen, Justierfehler bei nicht zusammenfallenden Markierungen erkannt und behoben werden. Zur Kalibrierung einer Projektionsvorrichtung können Referenzpunkte in oder bei dem Ersatzfeld vorgesehen sein, die durch Vorgabe entsprechender Referenz-Steuerwerte durch die Lichtmarke beleuchtbar sind. Die Referenzpunkte erlauben sowohl die Überprüfung einer korrekten Justierung der Projektionsvorrichtung als auch die Korrektur einer Fehljustierung und eine regelmäßige Kalibrierung, beispielsweise indem die Lichtmarke auf einen Referenzpunkt eingestellt und die dann aktuellen Steuerwerte als Referenz-Steuerwerte übernommen werden. Ein Referenzpunkt kann das Zielloch im Ersatzfeld sein. Vorzugsweise sind zusätzlich oder statt dessen weitere Referenzpunkte am Ersatzfeld vorhanden.The projection device can in turn have a plurality of spaced light sources contain, the illuminable areas of different sections of the replacement field can cover to positioning errors due to too flat beam incidence against the surface of the replacement field. The two or more areas that can be illuminated by light sources can also overlap or cover, thereby avoiding shadowing or, at the same time Marking by two light sources, adjustment errors in the case of non-coinciding ones Markings are recognized and corrected. For calibrating a projection device can provide reference points in or at the replacement field be, by specifying appropriate reference control values by the Light mark can be illuminated. The reference points allow both the verification a correct adjustment of the projection device as well as the correction misalignment and regular calibration, for example by setting the light mark to a reference point and then the current one Control values are adopted as reference control values. A reference point the target hole can be in the replacement field. Preferably are additional or instead there are other reference points on the replacement field.

Zum Informationsaustausch zwischen Überwachungseinrichtungen beim Zielfeld und Anzeigeeinrichtungen beim Ersatzfeld und ggf. beim Abschlagsfeld, soweit dieses auch vom Ersatzfeld weiter beabstandet ist, können Übertragungseinrichtungen bekannter Art, insbesondere Datenleitungen oder drahtlose Einrichtungen wie Funk- oder Infrarot-Sende-Empfangeinrichtungen vorgesehen sein. Statt einer direkten Kommunikation zwischen den Einrichtungen beim Zielfeld und denen beim Ersatzfeld kann der Datenaustausch auch über eine zentrale Stelle erfolgen, wo dann auch für alle Bahnen gemeinsame Bildauswertungen durchgeführt werden können.For the exchange of information between monitoring devices at the target field and display devices at the replacement field and possibly at the tee field, if this is also spaced further from the replacement field, transmission devices can known type, especially data lines or wireless Facilities such as radio or infrared transceivers are provided be. Instead of direct communication between the institutions for the target field and those for the replacement field, the data exchange can also be done via a central place, where then also common image evaluations for all railways can be carried out.

Für die Befestigung der Überwachungseinrichtungen und der Anzeigeeinrichtungen können beispielsweise Masten, Brücken oder dgl. insbesondere in Systemträgerbauweise, vorgesehen sein. Die erforderlichen mechanischen und elektrischen Mittel sind dem Fachmann bekannt.For fastening the monitoring devices and the display devices can, for example, masts, bridges or the like. be provided. The required mechanical and electrical means are known to the person skilled in the art.

Die Abbildung zeigt die für die Erläuterung der Erfindung wesentlichen Abschnitte einer Bahn eines Golfplatzes mit Abschlagsfeld AF, Zielfeld ZF und Ersatzfeld EF. Abschlagsfeld AF und Ersatzfeld EF sind in unmittelbarer Nachbarschaft angeordnet, so daß der Spieler das Spiel ohne größere Unterbrechung durchführen kann. Ein vom Abschlagsfeld AF abgeschlagener Ball gelange an einer Ballposition BP im Zielfeld ZF zur Ruhe. An einer das Zielfeld überspannenden Brückenkonstruktion K sind Beleuchtungskörper LQ befestigt, die den Spielbetrieb auch bei Dämmerung oder Dunkelheit erlauben. An der Brückenkonstruktion ist ferner in beispielsweise 6 m Höhe eine Videokamera BA befestigt, deren Bildbereich BB das gesamte Zielfeld einschließt. Das von der Kamera aufgenommene Bild wird über eine Übertragungsleitung UL zu einer Zentrale Z übermittelt, welche nach vorgebbaren Kriterien, beispielsweise Farbe, Bewegungsverhalten, Größe, Zeitzusammenhang mit Abschlag usw. eine Bildveränderung darauf überprüft, ob diese auf einen neu hinzugekommenen Ball zurückzuführen ist. Falls dies als zutreffend eingestuft wird, wird die relative Ballposition BP innerhalb des Bildes bestimmt. Die Ballposition kann bei einem in Zeilen und Spalten aufgeteilten Bildpunktraster der Bildfläche beispielsweise in Form eines Zahlenpaars aus Zeilennummer und Spaltennummer angegeben werden. Um Positionsfehler bei einer Dejustierung der Kameraausrichtung zu vermeiden, wird die Ballposition auf die Bildposition einer oder mehrerer Referenzmarkierungen RM und/oder die Bildposition des Zielloches H bezogen bestimmt und als dazu relative Ballposition angegeben. Die Referenzmarkierungen können innerhalb oder außerhalb des Zielfeldes ZF liegen, müssen aber vom Bildbereich BB der Kamera erfaßt sein.The figure shows the sections essential for the explanation of the invention a course of a golf course with tee field AF, target field ZF and Substitute field EF. Teeing field AF and replacement field EF are in the immediate vicinity arranged so that the player can play the game without major interruption can perform. A ball hit by the tee box AF arrives at a ball position BP in the target field ZF to rest. The target field on one spanning bridge construction K, lighting fixtures LQ are attached, which allow the game to operate even at dusk or in the dark. At the Bridge construction is also a video camera at a height of 6 m, for example BA attached, whose image area BB includes the entire target field. That from the picture taken by the camera becomes a via a transmission line UL Central Z transmits which according to predefinable criteria, for example Color, movement behavior, size, time connection with discount etc. an image change checks whether these are added to a new one Ball is due. If this is considered correct, the relative ball position BP determined within the image. The ball position can in the case of a pixel grid of the image area divided into rows and columns, for example in the form of a pair of numbers from row number and column number can be specified. Position errors when the camera orientation is adjusted To avoid the ball position on the image position of one or several reference marks RM and / or the image position of the target hole H determined and given as relative ball position. The reference marks can be inside or outside the target field ZF, but must be captured by the image area BB of the camera.

Die Auswerteeinrichtungen, die im Beispiel in der Zentrale Z vorgesehen sind, aber auch beim Zielfeld, beim Abschlagsfeld oder beim Ersatzfeld angeordnet sein können, bestimmen eine relative Ballposition und übermitteln diese zu einer Bedieneinheit BE und einer Projektionsvorrichtung PV beim Ersatzfeld EF. An der Bedieneinheit kann beispielsweise die relative Ballposition in Form eines Koordinaten-Wertepaars angezeigt werden. Es können aber auch das Zielfeld mit einer Ballpositionsmarke, das aktuelle Zielfeldbild u.ä. auf einem Bildschirm zur Anzeige gebracht werden. Über eine Tastatur der Bedieneinrichtung BE können ggf. verschiedene Funktionen der Anlage aufgerufen werden.The evaluation devices which are provided in the central Z in the example, but also arranged in the target field, the tee box or the replacement field can determine a relative ball position and transmit this to one Control unit BE and a projection device PV in the replacement field EF. The relative ball position in the form of a Coordinate value pairs are displayed. But it can also do that Target field with a ball position marker, the current target field image, etc. on one Screen to be displayed. Using a keyboard on the operating device Different functions of the system can be called up if necessary.

Eine an einer weiteren Brückenkonstruktion EK beispielsweise wieder in einer Höhe von 6 m über dem Ersatzfeld befestigte Projektionsvorrichtung PV projiziert mit einem eng gebündelten Lichtstrahl LS eine Lichtmarke LM auf das Ersatzfeld EF entsprechend den von den Auswerteeinrichtungen in der Zentrale Z oder über die Bedieneinrichtung BE vorgegebenen Steuerwerten. Die Ausrichtung des Lichtstrahls LS ist über die Steuerwerte veränderbar, was durch das Pfeilkreuz in der Abbildung angedeutet ist, so daß jede Position innerhalb des Ersatzfelds durch die Lichtmarke erreichbar ist. Die exakte Justierung und Steuerung der Positioniervorrichtung kann überprüft und die Steuerung kann kalibriert werden, indem die Lichtmarke LM auf eine Referenzposition wie das Zielloch EH des Ersatzfeldes oder einen von mehreren Referenzpunkten im oder beim Ersatzfeld gerichtet wird.One on another bridge construction EK, for example, again in one Projection device PV fixed at a height of 6 m above the replacement field with a tightly bundled light beam LS a light mark LM on the replacement field EF according to the evaluation devices in the central office Z or control values specified via the operating device BE. The alignment of the light beam LS can be changed via the control values, which by the arrow cross is indicated in the illustration, so that every position within of the replacement field can be reached by the light marker. The exact adjustment and Control of the positioning device can be checked and the control can be calibrated by moving the light mark LM to a reference position like that Target hole EH of the replacement field or one of several reference points in the or is judged at the replacement field.

Auch das Abschlagsfeld und das Ersatzfeld können zur Durchführung des Spielbetriebs bei Dämmerung oder Dunkelheit mit Beleuchtungseinrichtungen versehen sein.The tee box and the replacement field can also be used to carry out the Play operations at dusk or in the dark with lighting equipment be provided.

Die Erfindung ist nicht auf die beschriebenen Beispiele beschränkt, sondern im Rahmen fachmännischen Könnens in mancherlei Weise abwandelbar.The invention is not limited to the examples described, but in Can be modified in many ways within the framework of professional skills.
