Description

Technical Field

[0001] The present invention relates to the technical field of head-mounted equipment, and in particular to a head-mounted equipment for auxiliary training of golfers and a golf simulation training method. Background Art

[0002] In the sport of golf, golfers usually reach a certain level of hitting skills by practicing in an outdoor or indoor golf driving range before going to a real golf course to play. The lack of skills reflected by the golfers' hitting on the real golf course is usually improved by returning to the outdoor or indoor golf driving range to practice again and then returning to the real golf course. In the outdoor golf driving range, the position of the golfer is limited to an unchanging artificial lawn or space as small as a few square meters, which is very different from the teeing area, fairway area, rough area, obstacle area, bunker area, green area, etc. that need to be experienced on the actual golf course. In addition to the same limitations as the outdoor driving range, the indoor simulated driving range lacks the sense of contact with the real outdoor space. The difference between hitting the ball in the driving range and hitting the ball on the real golf course causes the psychological state of the golfers, especially the mid-to-high handicap golfers, to change, which further causes their physical state to change at the moment of hitting the ball on the actual golf course, and ultimately causes the golfers' better hitting effect on the driving range to often not be shown on the actual golf course.

[0003] Indoor golf driving ranges currently use one of the following two types of simulation projection technology or a combination of them: one is high-speed camera data acquisition combined with fixed screen projection technology, and the other is radar equipment data acquisition combined with fixed screen projection technology. Both of these projection technologies project on a screen far away from the golfer. The simulation effect of the distant screen is like the golfer watching a movie program, which is difficult to create a sense of reality in the golfer's mind. Indoor golf driving ranges cannot solve the problem of the psychological changes caused by the field changes and body movement required to hit the ball on the actual golf course.

[0004] Existing AR head-mounted devices use optical imaging technology to present augmented reality images on the lens screen. Specifically in the process of golf training, after the golfer hits the ball, the real-time swing data can be obtained through the sensor installed on the club, and the flight trajectory can be calculated and analyzed to simulate the landing point, etc. This method is equivalent to customizing the club, and in actual use, the size and weight of the club need to be adjusted at any time according to the training status, which makes it inconvenient to use and has poor practicality. Summary of the invention

[0005] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a head-mounted equipment for auxiliary training of golfers and a golf simulation training method. Through the head-mounted equipment, the hitting data of the golfer's hitting is obtained. After calculation and analysis by the application program, the optical projection device of the head-mounted equipment provides a high-definition moving projection that moves with the movement of the golfer's head. The simulated scene formed by the projection is combined with the actual golf ball to reduce the psychological difference between the golfer's hitting on the driving range and the actual field, reduce the physical state changes at the moment of hitting the ball, and achieve the purpose of maintaining the golfer's better hitting effect.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A head-mounted device for auxiliary training of golfers, comprising a part for measuring and analyzing parameters at the moment of hitting a ball, and a part for simulating and displaying ball flight and a court; the specific structure of the part for measuring and analyzing parameters at the moment of hitting a ball is as follows: it comprises a frame, and a plurality of miniature high-speed camera sensors installed on both sides and the middle of the frame; the specific structure of the part for simulating ball flight and a court is as follows: it comprises a frame, and temples connected to the frame, a semi-reflective semi-mirror with a built-in micro-display screen is installed on the frame as a lens, an optical projection device for forming an image on the lens is installed on the temples, and a graphics and data processing system is also included.

[0008] As a further improvement of the above technical solution:

[0009] The temples are equipped with a battery, a data connection and charging interface, a speaker, a microphone interface and a GPS module.

[0010] The frame is also equipped with WIFI and Bluetooth devices.

[0011] A golf simulation training method using a golfer's sports auxiliary training head-mounted device, wherein the micro high-speed camera sensor acquires motion pictures in a real scene, and transmits the collected initial data of the motion process to an application program, calculates the motion trajectory and key points after analysis, and presents the motion pictures in real time on a built-in micro display screen of a lens through an optical projection device, and the implementation method thereof is as follows:

[0012] Step 1: The graphics and data processing system is pre-set with the geographical environment data of the real golf course, and the geographical environment data is created into a three-dimensional model and presented on the built-in micro display screen of the lens. The coordinates of the golfer's actual hitting position are mapped to the geographical environment data of the real golf course;

[0013] Step 2: At the moment of the golfer's hitting the ball, multiple micro high-speed camera sensors accurately record and measure the golfer's swing data at a frequency of thousands or even tens of thousands of frames per second. The swing data is then compared, analyzed and calculated by the recording and analysis software installed on the golfer's handheld terminal, and the swing data of the golfer's hitting the ball is compared, analyzed and calculated with a large amount of data in the database to form the simulated calculation data of the hit, including initial speed, take-off angle, deviation angle, side spin, club speed, backspin, landing point, total distance and flight height;

[0014] Step 3: After the simulation calculation data is calculated and analyzed by the application, the simulated flight trajectory of the ball is finally obtained. The optical projection device provides a high-definition mobile projection that moves with the movement of the golfer's head. The simulated scene formed by the projection is combined with the actual hitting scene. The golfer can see the real golf ball and the simulated hitting area scene while hitting the ball, including the teeing area, fairway area, rough area, obstacle area, bunker area, and green area. After hitting the ball, the golfer can observe the actual flight trajectory of the golf ball in the simulated scene and the simulated landing position; the golfer's next shot will start in the simulated scene of the last landing position.

[0015] As a further improvement of the above technical solution:

[0016] At the moment the golfer hits the ball, multiple miniature high-speed camera sensors accurately record and measure the golfer's swing data at a frequency of thousands or even tens of thousands of frames per second, and analyze the real-time swing data to provide it to the golfer. The data values ​​include club head speed, attack angle of the ball, deviation angle, club face angle, club speed, club head trajectory, rotation axis, swing plane, ball speed, flight trajectory, length of time in the air, simulated landing point, prompting the golfer of precautions for the next swing, and providing the golfer with optional club head weight, shaft hardness and swing weight data for the next shot.

[0017] The beneficial effects of the present invention are as follows:

[0028] like Figure 2 and Figure 3As shown, in this embodiment, a golf simulation training method using a golfer's sports auxiliary training head-mounted device is performed. The micro high-speed camera sensor 5 obtains motion pictures in a real scene, and transmits the collected initial data of the motion process to the application program. After analysis, the motion trajectory and key points are calculated, and the motion pictures are presented in real time on the built-in micro display screen of the lens 1 through the optical projection device 2.

[0029] Step 1: The graphics and data processing system is pre-set with the geographical environment data of the real golf course, and the geographical environment data is created into a three-dimensional model and then presented on the built-in micro display screen of the lens 1, and the coordinates of the golfer's actual hitting position are mapped to the geographical environment data of the real golf course;

[0030] Step 2: At the moment of the golfer hitting the ball, multiple micro high-speed camera sensors 5 respectively record and measure the golfer's swing data at a frequency of thousands or even tens of thousands of frames per second; the swing data is then compared, analyzed and calculated by the recording and analysis software installed on the golfer's handheld terminal, and the swing data of the golfer hitting the ball is compared, analyzed and calculated with a large amount of data in the database to form the simulated calculation data of the shot including initial speed, take-off angle, deviation angle, side spin, club speed, backspin, landing point, total distance and flight height;

[0031] Step 3: After the simulation calculation data is calculated and analyzed by the application, the simulated flight trajectory of the ball is finally obtained. The optical projection device 2 provides a high-definition mobile projection that moves with the movement of the golfer's head. The simulated scene formed by the projection is combined with the actual hitting scene.

After hitting the ball, the golfer can observe the actual flight trajectory of the golf ball in the simulated scene and the simulated landing position; the golfer's next shot will start in the simulated scene of the last landing position.

[0032] At the moment the golfer hits the ball, multiple miniature high-speed camera sensors 5 accurately record and measure the golfer's swing data at a frequency of thousands or even tens of thousands of frames per second, analyze the real-time swing data, and provide it to the golfer.

[0034] The golfer's sports auxiliary training head-mounted device of this embodiment integrates a micro high-speed camera sensor and an optical projection system into glasses. Swing data recording, simulation data output, and augmented reality image generation and projection can be completed through one head-mounted device, greatly improving user experience and practicality.

[0035] This embodiment is provided with three miniature high-speed camera sensors 5, which can fully capture the picture of the golfer hitting the ball. After coupling the image data, a detailed and three-dimensional picture of the hitting ball is obtained, and the parameters of each hitting ball (swing) are accurately judged and calculated.

[0036] During the specific implementation process, the micro high-speed camera sensor 5 of this embodiment can fully capture the picture of the golfer hitting the ball. After coupling the image data, a detailed and three-dimensional picture of the hitting can be obtained, and the parameters of each hitting (swing) can be accurately judged and calculated. The micro high-speed camera sensor 5 of this embodiment can adopt existing commercially available products in this field. The multiple high-speed cameras and sensor systems built into the micro high-speed camera sensor 5 can obtain the moment when the ball takes off when the golfer hits each ball, and accurately record and measure the swing data of the golfer's hitting at a frequency of thousands or even tens of thousands of frames per second; the micro high-speed camera sensor 5 has a built-in processor, which analyzes the images taken by the micro high-speed camera sensor 5, obtains the swing data at the moment of hitting the ball, and transmits it to the specific recording and analysis software installed on the handheld terminal, and calculates the club head speed, hitting angle, deviation angle, and club speed of the golfer. A series of swing-related data are compared, analyzed and calculated with a large amount of data in the database to form a model of the actual and simulated calculation data of the shot, including initial speed, take-off angle, deviation angle, sidespin, club speed, backspin, landing point, total distance, flight altitude, etc. The data are imported into the image and data processing system with the preset geographical environment data of the real golf course, and the geographical environment data is established into a three-dimensional model and presented in the lens. The coordinates of the golfer's actual hitting position are mapped to the geographical environment data of the real golf course; by simulating data such as flight trajectory and landing point, the golfer is reminded of the precautions for the next swing.

[0037] When hitting the ball, the golfer can see the real golf ball and the simulated hitting area, such as the teeing area, fairway area, rough area, obstacle area, bunker area, green area, etc. After hitting the ball, the golfer can observe the actual golf ball's flight trajectory and simulated landing position in the simulated scene. The golfer's next shot will start in the simulated scene of the last landing position.

[0038] The head-mounted device of this embodiment has a built-in graphics and data processing system combined with specific recording and analysis software installed on the golfer's handheld terminal, a synchronous positioning and mapping system (SLAM), a micro display, near-eye optics, human-computer interaction and other technical links, and obtains real environmental information through a micro high-speed camera sensor 5, combines the sensor for positioning tracking and interaction, and uses optical perspective technology or other technologies to present real scenes and virtual scenes through a pair of half-reflective and half-mirror lenses installed in front of the eyes. The real environmental information is obtained through the camera, combined with the sensor for positioning tracking and interaction, and the virtual scene is generated through the micro display device and superimposed on the real scene.

[0039] Through optical perspective technology or other technologies, a pair of half-reflective and half-mirror lenses installed in front of the eyes are used to fuse and present real scenes and virtual scenes. The "real" of optical perspective comes from real light sources, which directly enter the glasses through the perspective optical system, while the "virtual" generated by the computer is magnified by the optical system and then reflected into the glasses. Finally, the two parts of information converge on the retina to form an imaging effect of virtual-real fusion.

[0040] The head-mounted device proposed in this application, in which the optical perspective technology principle and the adoptable display technology are relatively mature technologies in this field, other components already have relatively mature technical products, and dedicated analysis and control applications can also be designed and developed according to needs. Therefore, this application can be realized after special technical design and program upgrades based on the existing equipment and technology in the market.
