[0016] It should be noted that, unless there is a conflict, the embodiments in this application and the features described in the embodiments can be combined with each other. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] In the embodiments of the present invention, if there are directional indications (such as up, down, left, right, front, back, etc.), they are only used to explain the relative position relationship and movement status of the various components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0018] In addition, in this utility model, the terms "first," "second," etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of these features.

[0019] Please refer to Figures 1 and 2 The golf distance measurement system based on augmented reality glasses of the present invention includes a frame, a display module, a diffraction light waveguide lens, a control module, a distance measurement module, and a CMOS (Complementary Metal Oxide Semiconductor) camera module.

[0020] The rangefinder module, CMOS camera module, display module, and control module are integrated into the frame. The control module is electrically connected to the rangefinder module, CMOS camera module, and display module. The diffractive optical waveguide lens is used to receive the image projected by the display module.

[0021] The CMOS camera module is used to acquire an image of the point to be measured. The ranging module includes a laser diode for emitting a laser beam to the point to be measured and an avalanche diode for receiving the laser reflected by the point to be measured. The display module is used to project the image of the point to be measured and the distance information of the point to be measured onto the diffraction light waveguide lens.

[0022] Under the control of the control module, the ranging module drives the laser diode to emit an infrared invisible light, which is sent out through the transmitting optical path of the sending channel. When the infrared light hits the distant ranging target, a part of the infrared light will return, pass through the receiving optical path of the input channel, and then go to the avalanche diode to be converted into a corresponding analog signal. The signal is then returned to the controller of the control module. The controller is the central controller of the entire system and is responsible for calculating distance, receiving image information, projecting images, and other operations.

[0023] The utility model can be made within a volume of 5cm×2cm×1cm and a weight of 80g, thus meeting the volume and weight requirements for being integrated with glasses and worn during distance measurement.

[0024] As an embodiment, the ranging module further includes two 45-degree reflecting prisms, such as Figure 2 As shown, the laser diode is placed parallel to the CMOS camera module. The laser beam emitted by the laser diode is reflected by two prisms at 45 degrees into the optical path of the CMOS camera module (CMOS imaging optical path). The two prisms are placed parallel to each other at a 45-degree angle to the emitted laser beam. One prism is located in the original optical path of the laser diode, while the other is located in the optical path of the CMOS camera module. This reflects the laser beam emitted by the laser diode into the optical path of the CMOS camera module. This allows the CMOS camera module, laser diode, and avalanche diode to be integrated into a compact device, allowing it to be mounted on a frame, improving the user experience.

[0025] The utility model can make the infrared laser beam illuminate the center position of the CMOS imaging optical path. At this time, the CMOS camera module obtains the image of the distant ranging point through optical or optical plus digital zoom. After superimposing the auxiliary positioning information (i.e., ranging information), the image is projected onto the diffraction light waveguide lens through the display module.

[0026] Compared with the existing technical solutions that design the optical system and the electrical system separately, the optical path of the existing technical solutions is not optimized, resulting in an overly large overall structure and an inability to reduce the volume for integration into glasses; the present utility model effectively multiplexes the optical path of the ranging laser beam and the optical path of the CMOS camera module, thereby reducing the size of the device.

[0027] As an embodiment, the laser diode is an infrared laser diode, generally in the 1550nm wavelength range, which has little atmospheric absorption and is relatively safe for human eyes.

[0028] In one embodiment, the display module is a silicon-based Micro LED microdisplay, which is composed of silicon-based LEDs and corresponding lenses. The image displayed in the silicon-based Micro LED microdisplay is projected onto a diffractive light waveguide lens through a lens assembly.

[0029] As an embodiment, the frame is further integrated with an operation button electrically connected to the control module, through which the user can adjust the focus, start the distance measurement mode and perform distance measurement operations.

[0030] In one embodiment, the control module comprises a battery, a laser drive circuit, a receiving detection circuit, a signal amplification circuit, and a controller. The controller is electrically connected to the battery, the laser drive circuit, and the signal amplification circuit, which in turn is connected to the receiving detection circuit. The laser drive circuit and the receiving detection circuit are connected to the laser diode and avalanche diode, respectively.

[0031] In one embodiment, the frame includes a frame and two temples. When designing the battery positions, the batteries are evenly positioned on both temples, or on the other side of the frame corresponding to the distance measurement module, taking into account the balance of the glasses. This utility model combines lightweight, compact, and aesthetically pleasing design features.

[0032] The operating principle of this utility model is as follows: when a key is pressed to determine distance measurement, a laser diode emits a laser pulse. The laser light is projected through an optical path to the area surrounding the distance measurement point observed by the user. The laser light reflected from the distance measurement point is captured by the receiving detection circuit and the avalanche diode, triggering an electrical signal. The controller records the time difference between the laser diode emitting the laser light and the avalanche diode receiving the laser signal. The distance between the measured object and the user is calculated by reverse calculation based on the speed of light and the time difference. The distance information is then projected through the diffraction light waveguide lens into the user's eyes via the display module.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
