The present invention is directed to an efficient, affordable and relatively simple method and apparatus for accurately identifying a location of an object while being distant from that object. In one example described herein, the method and apparatus are deployed to accurately identify the location of a golf ball on a golf course while the tracker is positioned remote from that golf ball.
The game of golf is believed to have started in the 15th century. While innovation is not new to the game, it has primarily focused on a golfer's equipment. From improving the club and ball technology to introducing range finders and score keeping, the game of golf has indeed changed. To continue to evolve the game and draw in new participants, technology must enable the next gen golf experiences. The introduction and evolution of data into the game has had a remarkable impact.
On the market today, there is a plethora of physical devices that can capture object location and provide a distance to an object location, but there is no solution that does both without having to be at the exact location of, for instance, the ball.
Historically, current companion applications in the golf space are pure scorecards. Golfers finish their hole and mark down their score, as if it was a physical paper scorecard. Unfortunately, that means that those golfers do not have a way to look back at their shot locations and distances after the fact. During a round, they may use a rangefinder to calculate distance to their next shot and do mental math to understand the distance from their previous shot, but that data is not stored off or synced anywhere to tie it back to their hole performance. Some competitors in the golf world like The Grint®, SwingU®, and 18Birdies® utilize a GPS-only approach. A GPS-only approach requires a player to stand precisely next to the ball and log it in their smart device. In the course of competition play, however, GPS mobile apps are either banned or a deterrent to the rhythm of a golfer's game. Other solutions on the market today requires significant resources and investment per event/course in terms of physical hardware/technology.
The goal of the present method and apparatus is to overcome the foregoing shortcomings and to capture the position of a golf ball on a golf course consistently and accurately. The output provides the latitude and longitude of the ball along with, optionally, additional insights including surface type, club, stroke, penalties, etc. Accuracy can differ slightly depending on proximity to the ball but is typically within a matter of feet. Using affordable, consumer-grade technology, this method and apparatus may utilize one tracker, typically a volunteer, per hole to capture shot-level data while leveraging commercially available smart devices and range finders.
The method and apparatus aim to achieve comparable performance without the cost, operational challenges and resource needs of other products on the market today. The only equipment needed is a smart device with dual frequency GPS and compass capabilities and a rangefinder. Cellular connectivity or WiFi can upload data about a shot location directly to a cloud database. The following of a player's performance on a golf course can be used in gaming and gambling applications.
The method and apparatus are relatively simple enough and inexpensive to deploy. These attributes make systems like those described here available for professional golf organizations, college and junior golf teams and events and even individual club tracking of members or players generally.
In one example described herein, a method of accurately presenting the latitude and longitude of a golf shot location comprising the steps of providing a smart device that is GPS-enabled, has an internal compass, has a user interface, and comprises a processor that uses geocoordinates and distance measurements to calculate accurate golf ball location; providing a rangefinder; providing a tracker; during a golf game, after a player hits a golf ball on the golf course; identifying the latitude and longitude of the tracker on the golf course; measuring the distance between the tracker and the golf ball on the course using the rangefinder; obtaining the compass bearing in degrees from 1 to 360 between the ball and the smart device as measured by magnetic north using the compass in the smart device; calculating by the processor the magnetic declination angle of the tracker between geographic north and magnetic north based on the known latitude and longitude of each of the geographic north, the magnetic north and the location of the smart device; calculating by the processor the geographic bearing of the ball from the smart device by combining compass bearing and magnetic declination; calculating by the processor the latitude and longitude location of the ball by using the distance of the ball and the geographic bearing of the ball from the smart device; and displaying on the user interface of the smart device the latitude and longitude location of the golf ball. The method may further include the step of transmitting by the smart device the golf ball location to a central data collection processor. The central data collection processor may be proximate the golf course or remote from the golf course. The calculated latitude and longitude location of the golf ball may be visually displayed to the tracker and approved by the tracker before the location is saved. The rangefinder and smart device may be separate physical components or they may be a single component. The rangefinder and smart device may be mounted on a monopod. The smart device may include an application that displays to and prompts the tracker to complete tasks during the method steps. The tracker may follow a single player around the entire golf course and saves the ball locations of all of the shots for that individual, the tracker may follow a plurality of players around the entire golf course and saves the ball locations of all of the ball shots for each player in the group, and the tracker may be stationed at a single location on the golf course and record the golf ball location of the shot of all the golf players proximate the single location. The tracker may be a human or a robot. The processor may have a map of a golf course stored therein, and the golf ball location is displayed on the map of the golf course.
As explained earlier, the present method and apparatus, alternatively referred to herein as a system, enables a tracker to accurately locate the latitude and longitude of a golf ball on a golf course without having to stand over or directly adjacent the ball. This system may be also deployed in other applications where a remote tracker can obtain an accurate location of an object with the only requirement being that the tracker can visually see the object.
The description of the system and method utilizes some terms that are helpful to be defined. The following is a glossary of some of those terms.
1. Trackers—Operators of the smart device that runs the software application that guides the tracker through the location process and that makes the calculations necessary to locate the object/golf ball with an accurate latitude and longitude. The tracker is referred to throughout as a person, however, it is possible to deploy a robot that has the ability to remotely locate the ball on the golf course and run the software application automatically. At least one drawback of the use of robots would be cost and the need for human oversight of their operation.
2. Ball Distance—The horizontal distance between the smart device running the software application and where the ball has landed. This distance, also sometimes referred to as slope distance, is determined by a commercially available rangefinder that accounts for elevation changes to return the horizontal distance.
3. Smart Device Location—Latitude and Longitude of the smart device running the software application and that is carried by a tracker. These location coordinates are determined by a GPS enabled smart device that includes many or most of smart devices currently commercially available.
4. Compass Bearing—Compass reading in degrees from 1-360 between the tracker smart device and the ball as measured by the internal compass inside a smart device that measures bearing versus the Earth's magnetic north. Sometimes referred to as the heading, this is the direction in which a person would need to travel to reach a destination point. This measurement is automatically collected by the software application in the smart device.
5. Magnetic Declination—The angle between Geographic North and Magnetic North. This calculation is determined by the latitude and longitude of the smart device running the software application. This variable changes based on the latitude and longitude of the smart device, for example in the United States the Magnetic Declination can range anywhere from 20 to −11 degrees.
6. Geographic Bearing—A term similar to Compass Bearing but relative to Geographic North rather than Magnetic North. This value is determined by the application software by combining the already collected Compass Bearing and the Magnetic Declination.
The equipment needed to run the system herein includes a rangefinder, a smart device and the smart device application software. The rangefinder may be generally commercially available, but it may also be more sophisticated or custom designed for the location purposes described. The smart device must be GPS-enabled, and this may include commercially available smart phones or tablets or similar digital devices. The software application will be able to be installed and run by the smart device. The most easily assembled apparatus will include commercially available products where the rangefinder and smart device are separate components. It is possible that a smart device may be engineered and equipped to have a range finding function, thereby resulting in a single component to serve both functions. Similarly, a range finder may be designed to have a processor to run the software application and a user interface to input needed information. These combined devices are not commercially available today, but they may be developed in the future.
In
In one example of the method and apparatus, the latitude and longitude of a golf ball is determined with the use of a custom-built software application running on a GPS enabled smart device in combination with a commercially available range finder. These two are combined to determine the variables needed to mathematically determine the ball's latitude and longitude after it lands on the course with an accuracy of less than 2 meters of the ball's actual location. Once the location of the ball is determined, the findings along with participant identifying information may be sent in real time to a cloud-based application or other central data collection processor. This central data collection processor may be proximate a golf course, for instance at the location of a golf tournament. Alternatively, the central data collection processor location may be remote as in the example of a cloud-based processor.
The goal of the method and apparatus is ultimately to provide the latitude and the longitude of the ball after it lands on the golf course with an accuracy of less than 2 meters. The tracker must be able to do his without entering the field of play, meaning a tracker must be able to determine the Latitude and Longitude of the ball while also remaining 25-100 yards, or alternatively 5-200 yards, away from the ball. Latitude and Longitude are a system of lines used to describe the location of any place on Earth. Lines of latitude run in an east-west direction across Earth. Lines of longitude run in a north-south direction. All mapping capabilities and positioning of real-world objects on earth is done leveraging the Latitude and Longitude system.
The following is a brief summary of the method steps described herein.
Each of the foregoing steps will now be discussed in more detail. For simplicity purposes, all the illustrative diagrams are displayed on a 2D graph rather than a spherical globe.
Tracker Location: Latitude and Longitude of the smart device running the application software, and also the location of the tracker holding the smart device. In short, this location is essentially the latitude and longitude of where the tracker is standing. This point is provided by a GPS on the Smart Device. GPS Technology has become more accurate over the years and the present method leverages this existing technology to provide this point location.
With GPS coordinates alone, all that is known is where the tracker is standing. The tracker may be able to see the ball, but if the tracker were asked what the latitude and longitude of the ball was, they wouldn't be able to provide it. If allowed, the only way for the Tracker to determine the latitude and longitude of the ball with a GPS enabled device alone, would be for them to walk directly over to the ball and hold the GPS device on top of the ball. However, the trackers are not allowed to enter the field of play and must remain a remote distance away from the ball (usually 25-100 yards, or alternatively 5-200 yards away).
Ball Distance: Distance between the smart device and where the ball has landed. This is the Horizontal Distance to the ball compensating for elevation changes to return the true distance, also commonly referred to as Slope Distance. The horizontal distance is essentially the distance between the ball and the tracker. This distance is provided assuming the ball and the tracker are level to one another. If the ball and the tracker are not level to one another (ball is downhill or uphill from the tracker) the Range Finder will calculate the horizontal distance.
Compass Bearing: Compass reading, taken by the smart device internal compass, in degrees from 1-360 between the smart device and the ball. Sometimes referred to as the heading—the direction in which one would need to travel to reach a destination point. This is essentially the angle that the tracker would need to travel to find the ball relative to magnetic north. Magnetic North is the point on the earth at which a compass such as found in a smart device orients itself with.
Magnetic Declination: The angle between Geographic North and Magnetic North determined by the latitude and longitude of the smart device/tracker. This angle changes based on the latitude and longitude of the smart device, for example in the United States the Magnetic Declination can range anywhere from 20 to −11 degrees. This was described above when comparing the relation of Magnetic North and Geographic North from the East and West Coasts. In
Geographic Bearing: A term similar to Compass Bearing but relative to Geographic North rather than Magnetic North. In short, the Geographic Bearing is a term that is referring to the Compass Bearing added to the Magnetic Declination to return the angle between True North and the ball. This is important as True North is what is leveraged on the Latitude and Longitude Coordinate System. For example, if the Compass Bearing between the Tracker and the Ball is 110 degrees, and the Magnetic Declination for where the Tracker is located is 11 degrees, the Geographic Bearing is 121 degrees. The resulting 121 degrees is the direction relative to true north that one would need to travel to find the Latitude and Longitude of the ball. This is the final point needed to determine the Latitude and Longitude of the Ball.
With all this information, it is known precisely how far the ball is away from the smart device/tracker location and in what direction. These variables are then used to run a trigonometry equation which will result in the Latitude and Longitude of the ball.
Turning now to the
Other variations of the system and process described herein are possible as described in the following alternative examples. Still further variations are possible.
In this version of the method and apparatus disclosed herein, the latitude and longitude location of the ball is determined with the use of a software application running on any smart device without the requirement for onboard GPS in the smart device that is required in the earlier example 1 discussed herein. In this example, the GPS location for the Tracker is gathered through a Range Finder that has the capability of capturing the tracker's location. This location found through the Range Finder is then transmitted in real time to the Smart Device running the software so that it may be used in the same manner as the rest of the earlier example. Just as in the earlier example, these devices are combined to determine the variables needed to mathematically determine the ball's latitude and longitude after it lands on the course with an accuracy of less than 2 meters of the ball's actual location. Once the location of the ball is determined, the findings along with participant identifying information are sent in real time to a cloud-based application.
In this version, the latitude and longitude of the ball is determined with the use of an application running on any smart device without the requirement for onboard GPS OR Compass Sensors that are required in the earlier example 1. In this example, the GPS location for the Tracker is gathered through a Range Finder that has the capability of capturing the tracker's location. At the same point that the Ball Distance is captured, the Range Finder will also gather the tracker's Compass Bearing. This location and compass bearing found through the Range Finder is then transmitted in real time to the Smart Device so that it may be used in the same manner as the rest of example 1. Just as in example 1, these devices are combined to determine the variables needed to mathematically determine the ball's latitude and longitude after it lands on the course with an accuracy of less than 2 meters of the ball's actual location. Once the location of the ball is determined, the findings along with participant identifying information are sent in real time to a cloud-based application.
In this version, the latitude and longitude of the ball is determined with the use of a software application running on any smart device without the requirement for onboard GPS that is required in example 1. This example requires the use of known location markers preset throughout the course. These preset, known locations are points loaded into the application where the latitude and longitude are already known. Trackers then position themselves next to one of these known points so that the use of GPS is not required. Just as in example 1, a commercially available range finder is then used to capture the Ball Distance. Just as in example 1, these devices are combined to determine the variables needed to mathematically determine the ball's latitude and longitude after it lands on the course with an accuracy of less than 2 meters of the ball's actual location. Once the location of the ball is determined, the findings along with participant identifying information are sent in real time to a cloud-based application.
