Description

Laser ranging smart golf glasses Technical Field

[0001] The present invention relates to the field of laser ranging and glasses, in particular to smart golf glasses with a laser ranging function. Background Art

[0002] Laser rangefinders have become standard equipment for golfers. They measure the distance from the user to the flagpole and the angle between the user and the flagpole, allowing them to choose the club, shot angle, and force based on experience, ensuring the golf ball lands precisely in the desired area. However, each use requires a long time and is inconvenient to carry. Integrating a laser rangefinder into glasses, creating laser rangefinder smart golf glasses, would greatly facilitate golfers. Laser rangefinder smart golf glasses primarily incorporate a laser emission system, a laser reception system, and a camera and projection system. The camera and projection system aligns the aiming reticle (frame, dot) at the center of the camera image with the laser emission center point, allowing the laser to accurately aim at the flagpole. The measured distance is the distance between the flagpole and the user. Projecting the distance onto the glasses facilitates the user's visual experience, allowing them to clearly see whether the aiming point is the flagpole. To reduce the size and weight of laser rangefinder golf glasses and make them suitable for golfers, the laser transmitter, receiver, and camera systems must be arranged and fixed in a row, all three in parallel, ensuring that the aiming reticle (frame, dot) in the center of the captured image is the aiming point of the laser emission. A high-brightness display screen is used to project the aiming point (crosshairs, frame) into the field of view of the glasses, which can project not only the aiming point (crosshairs, frame), but also digital images such as distance, angle, slope compensation, and mode. Combined with GPS and course maps, a simulated fairway curve is calculated and displayed. Images can be stored and replayed to guide players to improve their skills, and can be transmitted and shared with others in a timely manner. The smart glasses can also be combined with helmets, hats, and head covers, and can also be used for other outdoor activities such as hunting, as well as military purposes.

[0003] CN206096663U discloses glasses for golf distance measurement. In this patent, a first laser distance sensor detects the distance between it and the hole at the bottom of the flagpole, while a second distance sensor detects the distance between it and the golf ball directly below it. The Pythagorean theorem is then used to calculate the distance between the golf ball and the hole at the bottom of the flagpole. This process requires knowing at least one angle. Since the surface of a golf course is typically not flat, the calculation method in this patent directly defines the player as being at right angles to the surface. However, in reality, the surface of a golf course is undulating. This resulting value is inaccurate.

[0004] CN204989666U discloses a multifunctional pair of glasses that uses a phase rangefinder. However, the phase rangefinder has the disadvantage of limited range measurement, measuring only tens of meters outdoors in strong sunlight. Furthermore, at greater distances, the laser spot is very faint, making it impossible to use the visible laser spot to aim at the target. Consequently, the measured distance may not necessarily reflect the target's distance. Therefore, the glasses are not suitable for golfers.

[0005] Summary of the Invention

[0006] In view of the above background technology, the present invention provides a pair of smart golf glasses that can measure distance, height and angle, and project images of the scenery in front.

[0007] The technical solution adopted by the present invention is: laser ranging intelligent golf glasses, including lenses and a glasses frame, the glasses frame has two glasses legs, and also includes a laser emitting system, a laser receiving system, a camera system, a display and projection system, a circuit board and a battery. The laser emitting system and the laser receiving system are arranged on the glasses frame, and the optical axes of the laser emitting system and the laser receiving system are parallel. The display and projection system is arranged on the glasses frame or the glasses legs and displayed on the glasses. The laser emitting system includes a laser emitting antenna and a laser. The laser receiving system includes a laser receiving antenna and a laser detector. The laser and the laser detector are connected to the circuit board. The circuit board and the battery are arranged on the glasses legs. The laser emitting system emits laser with the dividing line set in the center of the projected image as the aiming point. The center point of the projected image of the display and projection system (set with dividing lines, frames, and points) is consistent with the laser emitting point.

[0008] Furthermore, it also includes a camera system composed of a camera and a COMS image chip, and the three optical axes of the camera system, the laser emitting system and the laser receiving system are parallel to each other.

[0009] Furthermore, the display and projection system includes a display screen, a projection lens, an optical waveguide coupling-in area, and an optical waveguide coupling-out area. The display screen and projection lens are arranged on the frame or the temples, and the optical waveguide coupling-in area and the optical waveguide coupling-out area are arranged on the lenses. The projected image enters from the optical waveguide coupling-in area and is displayed from the optical waveguide coupling-out area.

[0010] Furthermore, the display screen is a reflective display screen, and the image is projected into the optical waveguide coupling region through a projection lens. The reflective display screen is a MicroOLED screen, and an aiming reticle is edited on the screen.

[0011] Furthermore, the display and projection system may also adopt a prismatic projection system, which includes a display screen, a projection lens, and a cemented prism. The cemented prism is formed by gluing two triangular prisms together, and the gluing surface of one prism is coated with a semi-reflective and semi-transparent dichroic film.

[0012] Furthermore, the laser emitting system, laser receiving system and camera system are arranged side by side as a whole and are arranged on the legs of glasses or hung on a nose frame.

[0013] Furthermore, the display and projection system can be replaced by a display system, which uses a high-transmittance liquid crystal display screen. The high-transmittance liquid crystal display screen directly serves as a lens to directly display the laser emission aiming reticle, distance value, angle value, and slope compensation value.

[0014] Furthermore, the circuit board is arranged on the first of the glasses legs, and the battery is arranged on the second of the glasses legs.

[0015] Furthermore, it also includes a solar charging panel arranged on the legs of the glasses.

[0016] Furthermore, the circuit board is provided with a GPS positioning system and a built-in global golf course map; or / and a Wifi module or / and a Bluetooth module, which is used to connect to a mobile phone, call up a map of the course, combine it with the real scene captured by the camera, simulate various hitting plans and goal paths, and display animations to guide hitting.

[0017] Furthermore, the golf glasses are used in conjunction with a hat, a helmet or a sports head cover.

[0018] The invention can measure distance, height angle, calculate slope compensation value, simulate (animate) and display the flight path of golf ball, and project the scene in front.

[0019] The advantage of the present invention is that it combines the laser emission and laser receiving optical systems with the camera system to ensure that the three optical axes are parallel, and then uses the center point of the projected image as the aiming point for the laser emission. It can accurately aim at the target and measure the distance value of the target, as well as the pitch angle value between the target and the glasses and the horizontal plane, accurately calculate the slope compensation value for hitting the ball, and guide golfers to choose the club, hitting angle and force; the multiple display methods used (optical waveguide, prism projection system, high-transmittance liquid crystal display, etc.) are different, and the cost varies, giving users room for choice.

The laser emitting antenna 1 and the laser 6 constitute a laser emitting system, the laser receiving antenna 2 and the laser detector 5 constitute a laser receiving system, the camera 3 and the COMS image chip 4 are connected to constitute a camera system, the laser emitting system, the laser receiving system, and the camera system are arranged on the glasses frame, and the three optical axes of the laser emitting system, the laser receiving system, and the camera system are parallel to each other. The glasses also include a display and projection system. The display and projection system 10 includes a display screen, a projection lens, an optical waveguide coupling-in area 11, and an optical waveguide coupling-out area 12. The display screen and projection lens are mounted on the frame or temple. The optical waveguide coupling-in area 11 and the optical waveguide coupling-out area 12 are mounted on the lens 9. The projected image enters from the optical waveguide coupling-in area 11 and is displayed from the optical waveguide coupling-out area 12. A circuit board 7 and a battery 8 are mounted on the temple. The laser emission system uses the center point of the projected image as the aiming point, and the center point of the projected image is consistent with the laser emission point. The laser emission system, laser receiving system, camera system, and projection system are powered by batteries mounted on the temple.

[0035] The display screen is a reflective display screen. It is a MicroOLED screen with an aiming reticle programmed on it. The display screen can display the image captured by the camera, and overlay the edited aiming reticle (frame, dot) and measured distance values, angle values, mode symbols, etc. on the image, projecting the image onto the optical waveguide outcoupling area 12 in the field of view of the eyeglass lens via an optical waveguide.

[0036] According to the above method, the laser emission, reception, camera, display screen, and projection system are combined into a whole through the glasses frame. Text, aiming graticules (frames, dots), etc. can be edited on the display screen. The center point of the image projected by the projection system can be used as the graticule (frame, dot) as the aiming point for laser emission, ensuring that the laser emission point is consistent with the center point of the real-time image projected in the glasses, and the graticule is used to aim at the target; when the center point projected in the glasses is used to aim at the target, the laser 6 emits laser light to the target through the laser emission antenna 1; the laser echo is focused on the laser detector 5 through the laser receiving antenna 2, and the circuit board 7 calculates the distance to the target based on the transmission time required from the emission to the reception of the laser signal.
