Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0045] In related technologies, a rangefinder is an electronic device that uses optics, acoustics, electromagnetic waves and other principles to measure the distance between two objects. Among them, the laser rangefinder is one of the most common types. It emits laser pulses to the target object, then measures the time or phase difference of the laser's round trip, and calculates the distance by multiplying the speed of light by half the time. This type of rangefinder has high accuracy and fast response speed, and is widely used in construction, surveying, golf, hunting and other fields.
[0046] When measuring the distance of small or distant targets, the rangefinder uses a point-to-point rangefinder to scan the target to find the smallest or largest target as the target we need to measure the distance. In this case, because the target is hundreds of meters away, the target will be very small, and the desired target distance may be missed during the scanning process, resulting in the measurement result not being the desired target, which leads to an incorrect distance judgment.
[0047] like Figure 1 As shown, in order to solve the above technical problems, an embodiment of the present application provides a method for a rangefinder to lock a target, and the method for a rangefinder to lock a target includes the following steps:
[0048] S100: measuring a target object at a measuring point using a rangefinder to obtain a first measuring distance and a first measuring angle relative to the first measuring distance;
[0049] S200: controlling the rangefinder to deflect along a preset direction to change a real-time measurement angle of the rangefinder, and obtaining a second measurement distance measured by the rangefinder on the deflection path and a second measurement angle corresponding to the second measurement distance; wherein the second measurement distance represents a minimum measurement distance or a maximum measurement distance;
[0050] S300: Compare the second measurement angle with the first measurement angle. If the second measurement angle is equal to the first measurement angle, it indicates that the position of the target object is locked.
[0051] It should be noted here that it can also be understood that, as long as the difference between the first measurement angle and the second measurement angle is within the set error range, it can also be determined that the first measurement angle and the second measurement angle are equal.
[0052] This technical solution proposes an improved rangefinder target locking method, aiming to improve the accuracy and reliability of long-distance or small target measurement.
[0053] Multi-point measurement and comparison: First, the distance and angle of the target are measured at the initial measurement point. This step provides basic distance measurement information and target direction.
[0054] Dynamic Deflection Scanning: The rangefinder then deflects and continuously measures along a preset path (which may be a circle or a sector area). This strategy allows the system to search for targets over a larger area, especially when the initial measurement may not accurately capture the target because it is too small.
[0055] Find the second measurement distance: During the deflection scan, the system records the minimum value of all measured distances and the corresponding angle. The minimum distance often represents the measurement result that is most directly pointing to the target, which helps to filter out non-target interference. Alternatively, during the deflection scan, the system records the maximum value of all measured distances and the corresponding angle. The maximum distance often represents the measurement result that is most directly pointing to the target, which helps to filter out non-target interference.
[0056] It should be noted that during the deflection process, only one of the maximum and minimum values will appear.
[0057] Angle comparison locking mechanism: By comparing the second measurement angle corresponding to the second measurement distance obtained with the initial first measurement angle, if the two are consistent, it is confirmed that the second measurement distance is the actual distance of the target, thereby achieving accurate locking of the target.
[0058] Obviously, this method significantly improves the accuracy of locking on to distant or tiny targets and reduces the possibility of misjudgment by increasing the number of measurement points and angle comparisons. Moreover, for measurements in complex environments, such as when there are multiple interferences in the environment, this technology can more effectively eliminate interference and lock on to the correct target. The automated locking mechanism reduces the need for manual adjustments and repeated distance measurements by the user, improving the convenience and efficiency of use. In particular, whether it is building measurement, wildlife observation, military reconnaissance or other long-distance monitoring scenarios, this technology can provide more reliable measurement data. In summary, the proposed rangefinder target locking method effectively solves the limitations of traditional point-to-point ranging in dealing with distant and small targets through intelligent dynamic scanning and comparison strategies, and is an important technical innovation to improve ranging accuracy and efficiency.
[0059] In some embodiments, measuring the target object at a measuring point using a rangefinder to obtain a first measuring distance and a first measuring angle includes:
[0060] The rangefinder has a distance measurement module and an angle measurement module. The distance measurement module and the angle measurement module of the rangefinder are used to measure the target object at a measurement point to obtain a first measurement distance and a first measurement angle.
[0061] In these embodiments, the design of the rangefinder follows the basic measurement principle, and mainly realizes the accurate measurement of the target object through two core modules: a distance measurement module and an angle measurement module.
[0062] Distance measurement module: This module is one of the cores of the rangefinder, usually using laser ranging technology. It emits a laser pulse to the target and records the time from the pulse being emitted to the reflected echo being received. Since the speed of light is known, the rangefinder can calculate the total distance of the laser from the target surface to and from the target surface based on this time difference, and then obtain the actual distance of the target. This process is fast, accurate, and works under a variety of lighting and weather conditions.
[0063] Angle measurement module: This module is responsible for measuring the angle between the rangefinder and the target in the horizontal and / or vertical planes, which is essential for determining the precise position of the target in three-dimensional space. Angle measurement can be achieved through built-in electronic tilt sensors (such as gyroscopes, accelerometers), which can sense the tilt angle of the rangefinder itself and calculate the target angle relative to the horizontal or vertical direction. In some advanced models, angle measurement may also include an automatic correction function to compensate for errors caused by slight hand shaking or unstable operation of the user.
[0064] The user first aims at the target through the rangefinder's aiming system (such as a built-in sight or a crosshair on the display). The distance measurement module is activated, and the instrument automatically emits a laser and calculates the target distance. At the same time or successively, the angle measurement module works to measure the horizontal and / or vertical angles. The rangefinder's microprocessor integrates the distance and angle information, and may also apply algorithms such as triangulation calculations, and finally outputs the three-dimensional spatial coordinates of the target or directly displays the measured distance and angle of the target.
[0065] For example, the angle measurement module is configured as an angle sensor, which includes a lateral angle or a pitch angle measurement function, which can be implemented by a compass or a gyroscope. The pitch angle can be implemented by an acceleration sensor, a gyroscope, a gravity pendulum, a liquid level bubble, etc.
[0066] In some embodiments, the rangefinder has a distance measurement module and an angle measurement module, and the distance measurement module and the angle measurement module of the rangefinder are used to measure the target object at a measurement point to obtain a first measurement distance and a first measurement angle, including:
[0067] The rangefinder has a distance measurement module and an angle measurement module. The distance measurement module and the angle measurement module of the rangefinder are used to measure the target object at a measurement point with a measurement frequency greater than 1 Hz to obtain a first measurement distance and the first measurement angle.
[0068] In this embodiment, the rangefinder continuously monitors the target object at a high measurement frequency (greater than 1 Hz) by integrating the distance measurement module and the angle measurement module, which brings the following additional beneficial effects:
[0069] Real-time dynamic tracking: A measurement frequency greater than 1 Hz means that at least one measurement is taken per second, which is particularly useful in dynamic environments. It can achieve real-time or near real-time target tracking, and quickly capture the position changes of the target even when it is moving, which is crucial for applications such as sports event tracking, wildlife observation, or military target monitoring.
[0070] Improve data accuracy and resolution: High-frequency measurement can collect more information about the target's motion, thereby reducing the impact of noise through data processing techniques (such as filtering algorithms) and improving the accuracy and time resolution of the final measurement results. This is extremely critical for application scenarios that require highly accurate measurements, such as precision engineering measurements, drone obstacle avoidance systems, etc.
[0071] Enhanced stability and response speed: High-frequency data acquisition helps the system respond to changes in target position more quickly, improving system stability and response speed.
[0072] Data analysis and prediction: Frequent measurement data provides rich materials for subsequent data analysis, which can be used to develop advanced functions such as predicting target movement trajectory and analyzing target behavior patterns. This is of great value for areas such as hunting that require trend prediction and behavior analysis.
[0073] Optimize resource allocation: In the case of multiple target tracking or limited resources, high-frequency measurement allows the system to quickly re-evaluate the importance of each target and promptly adjust the rangefinder's observation direction or resource allocation to ensure effective monitoring of the most critical or urgent targets.
[0074] In summary, in these embodiments, by adopting a measurement frequency greater than 1 Hz, the rangefinder can not only achieve real-time dynamic tracking of the target, but also significantly improve the measurement accuracy, system response speed, and depth and breadth of data processing, thereby broadening its practicality and effectiveness in various complex application scenarios.
[0075] In some embodiments, controlling the rangefinder to deflect along a preset direction to change a real-time measurement angle of the rangefinder, and acquiring a second measurement distance measured by the rangefinder on the deflection path and a measurement angle corresponding to the second measurement distance, comprises:
[0076] The rangefinder is controlled to deflect along a preset direction to change a real-time measurement angle of the rangefinder, and a second measurement distance measured by the rangefinder on a deflection path at a measurement frequency greater than 1 Hz and a measurement angle corresponding to the second measurement distance are obtained.
[0077] In these embodiments, by controlling the rangefinder to deflect along a preset direction at a measurement frequency greater than 1 Hz, the accuracy and efficiency of locking the target are further enhanced. The addition of this technical detail brings the following significant advantages:
[0078] Improved real-time dynamic adaptability: During the deflection scanning process, high-frequency measurements (greater than 1Hz) can quickly respond to subtle changes in the target position, especially when the target is moving or the environmental conditions are unstable, ensuring the system's continuous and instant tracking of the target position and improving the dynamic adaptability of the locked target.
[0079] Improve target capture accuracy: Through high-frequency measurement, even when the target is very small or far away, it is possible to detect tiny fluctuations in distance more carefully, thereby accurately identifying the second measurement distance and its corresponding precise angle, reducing locking errors caused by accidental measurement errors, and improving target capture accuracy.
[0080] Optimize the target confirmation process: Under continuous deflection and high-frequency measurement, the system can collect and analyze the measurement data on the entire preset path more quickly, accelerating the target confirmation process. Once the second measurement distance and its corresponding second measurement angle are found, the target is locked almost instantly, improving operational efficiency.
[0081] Enhanced anti-interference capability: In complex environments, high-frequency measurement helps to quickly filter out irrelevant background interference information, especially when there are multiple close targets or reflection sources. It can more reliably identify and lock the real target, thus improving the reliability of the measurement results.
[0082] Optimize user operation experience: This implementation method reduces the user's manual adjustment and waiting time, making the entire ranging process smoother and more responsive, improving the user's operation experience and satisfaction, especially in situations that require quick response, such as competitive sports, outdoor adventures, or emergency rescue.
[0083] In summary, by combining deflection scanning with high-frequency measurement greater than 1 Hz, this embodiment not only enhances the target locking capability of the rangefinder in complex environments and long-distance conditions, but also improves measurement efficiency and user experience, demonstrating the advancement and practicality of the technology.
[0084] In some embodiments, controlling the rangefinder to deflect along a preset trajectory includes:
[0085] The rangefinder has a display module, which is used to display the measured distance, the measured angle and the deflection direction, so as to control the rangefinder to deflect along a preset direction.
[0086] In these embodiments, the integrated display module is used to guide and control the rangefinder to deflect along a preset trajectory, thereby increasing the intuitiveness of the operation and user interactivity, and specifically achieving the following advantages:
[0087] Intuitive display information: The display module can display the currently measured distance, angle information and recommended deflection direction in real time, allowing users to understand the current measurement status and next operation instructions at a glance. This real-time feedback mechanism helps users quickly adjust the direction of the rangefinder to ensure measurement accuracy.
[0088] Precisely guided deflection: By clearly indicating the deflection direction on the screen, the user can more accurately control the movement of the rangefinder. Even when the target cannot be seen directly or the target is small and difficult to judge intuitively, precise adjustments can be made according to the on-screen instructions to reduce human errors. In addition, it can ensure that the rangefinder is controlled to move back and forth along the deflection path with repeatability and accuracy.
[0089] Optimize the operation process: Combined with the guidance of the display module, users can more systematically measure according to the preset trajectory, avoiding blind exploration and repeated measurements, and improving work efficiency. This is especially important for applications that require multiple measurements or in complex environments.
[0090] Improve user interaction experience: The intuitive graphical interface and clear operation prompts make user interaction more friendly. Even first-time users can quickly get started, which lowers the usage threshold and enhances the user experience.
[0091] In some embodiments, the method for the rangefinder to lock a target further includes:
[0092] The display module displays the position of the locked target object in a dot matrix or graphic manner.
[0093] In this embodiment, the display module takes a display screen as an example. The display screen displays the position of the locked target in a dot matrix or graphic form, which is an intuitive display form to improve user experience and measurement accuracy. These two methods have their own characteristics, aiming to help users confirm the target position and measurement results more clearly and quickly:
[0094] The dot matrix method usually refers to the use of LED dot matrix screens or similar pixel display technologies to represent the target position and related measurement information as a collection of dots or pixels. This display method can intuitively indicate the target direction and distance by lighting up dots of different brightness and colors. For example, the bright spot or pattern of bright spots on the screen can move as the rangefinder rotates. When the rangefinder locks on the target, the bright spot is stable, and the user can intuitively judge the azimuth of the target by the position of the bright spot and the reference scale on the interface.
[0095] The graphical method goes a step further and uses a graphical user interface (GUI) to display richer image information. This may include map outlines, target icons, crosshairs, or more complex 3D views. In the graphical display, the target position not only appears in the form of coordinate points, but can also be combined with arrows, aiming circles or other graphic symbols, or even directly display a simulated image of the target on the screen, indicating the target direction and distance in a way that is closer to the real visual experience. In addition, the graphical interface can also contain more information, such as the target's lock status, measurement error range, wind direction and wind speed impact prompts, etc., to provide users with more detailed and intuitive measurement feedback.
[0096] Whether it is a dot matrix or graphic display, its core goal is to help users quickly and accurately identify and confirm targets, reduce the chance of misinterpretation, and ensure the reliability and practicality of measurement results. By updating the display content in real time, users can adjust their position or device angle according to the instructions on the display until they get the ideal measurement results, which plays an important role in hunting, golf or any activities that require precise positioning.
[0097] In some embodiments, the rangefinder has a distance measurement module and an angle measurement module, and the distance measurement module and the angle measurement module of the rangefinder are used to measure the target object at a measurement point to obtain a first measurement distance and the first measurement angle, including:
[0098] The rangefinder has a distance measurement module, an angle measurement module and a target aiming module. The target aiming module of the rangefinder is used to observe the target object, and the distance measurement module and the angle measurement module are used to measure the target object at a measurement point to obtain a first measurement distance and a first measurement angle.
[0099] In these embodiments, the design of the rangefinder integrates multiple functional modules to achieve accurate measurement of the position of the target object. Specifically, it combines the ability of distance measurement, angle measurement, and target observation through the target aiming module, which greatly improves the convenience and accuracy of measurement. The following is a detailed description of this process:
[0100] Distance measurement module: This part usually uses laser ranging technology, which transmits laser pulses to the target object and receives the reflected signal, and calculates the precise distance between the target and the rangefinder based on the speed of light and time difference. This method is fast and accurate and is suitable for long-distance measurement under various environmental conditions.
[0101] Angle measurement module: This module is mainly used to determine the horizontal and vertical angles (elevation or depression) of the target relative to the rangefinder. This is usually achieved through a built-in electronic theodolite or tilt sensor, which can accurately measure angle changes and provide necessary data support for subsequent distance correction and three-dimensional coordinate calculation.
[0102] Target aiming module: This is a very practical function. It not only helps users to clearly observe distant targets and improve aiming accuracy, but may also be equipped with crosshairs or other aiming assistance functions to ensure that the target is correctly aligned before measurement. This is especially important for finding and locking targets in complex environments or long-distance conditions. For example, the target aiming module is set as a telescope module.
[0103] By combining these three modules, the rangefinder can complete all-round measurement of the target at the measuring point:
[0104] Step 1: The operator first observes and locks the target through the target aiming module, and uses its magnification function to clearly identify the target details to ensure the accuracy of the measurement.
[0105] Step 2: Next, activate the distance measurement module, emit laser to the target and record the echo time to calculate the straight-line distance of the target.
[0106] Step 3: At the same time, the angle measurement module works to measure the angle deviation from the rangefinder to the target in the horizontal and vertical planes.
[0107] Step 4: Finally, the processor inside the rangefinder will use mathematical methods such as trigonometric functions to calculate parameters such as the target's precise position or height based on the distance and angle information obtained.
[0108] This integrated rangefinder is widely used in surveying, construction, hunting, golf courses and other fields. Its high efficiency and convenience greatly improve the efficiency and accuracy of outdoor measurement work.
[0109] In some embodiments, the display module has a ring-shaped target orientation display icon, which is located in the middle of the target aiming module, and the optical axis of the distance measurement module is coaxial with the ring-shaped target orientation display icon to simulate the display of the direction and deviation angle of the target object.
[0110] In these embodiments, the design of the display module further enhances the user experience and practicality of the rangefinder, especially in scenarios requiring precise positioning and direction indication.
[0111] Specifically, the introduction of the ring-shaped target position display icon has the following characteristics and advantages:
[0112] Intuitive azimuth indication: The circular target azimuth display icon usually includes scales or marks to indicate the azimuth of the target object relative to the rangefinder. This design allows the user to see the direction and position of the target on the horizontal plane at a glance when observing the target, which is particularly useful for tasks such as navigation, map making or field positioning.
[0113] Coaxial alignment: The optical axis of the distance measurement module is coaxial with the ring-shaped target position display icon, which means that when the user observes and adjusts to the target through the target aiming module, the ranging beam is also emitted along the observation center direction, ensuring the accuracy and intuitiveness of the measurement. This coaxial design simplifies the operation process and improves the consistency and reliability of the measurement.
[0114] Integrated in the center of the telescope's field of view: The ring-shaped target azimuth display icon is located in the middle of the target aiming module, ensuring that during the observation process, the user can simultaneously refer to the azimuth information and perform measurements without shifting their sight, reducing the error caused by switching sights and improving the continuity and fluency of observation and measurement.
[0115] Enhanced functionality: In addition to basic distance and angle measurement, the integrated ring-shaped surround target position display also enables the rangefinder to have the function of a simple compass. For outdoor adventures, terrain mapping and other fields, this multi-functional integration significantly enhances the scope of application and value of the equipment.
[0116] In summary, this rangefinder design not only provides accurate measurement data through its sophisticated display module design, but also provides additional azimuth indication capability, allowing users to complete positioning and measurement tasks more quickly and accurately in complex environments.
[0117] In some embodiments, the rangefinder has a distance measurement module and an angle measurement module, and the distance measurement module and the angle measurement module of the rangefinder are used to measure the target object at a measurement point to obtain a first measurement distance and the first measurement angle, including:
[0118] The rangefinder has a distance measurement module, an angle measurement module and an image sensor. The image sensor of the rangefinder is used in conjunction with a display module to observe the target object, and the target object is measured at a measurement point in conjunction with the distance measurement module and the angle measurement module to obtain a first measurement distance and a first measurement angle.
[0119] In these embodiments, the image sensor cooperates with the display module, and the image sensor is usually a CMOS or CCD sensor, which is responsible for capturing the real-time image of the target object. This allows the user to directly observe the target through the display screen (display module) of the rangefinder, and the target can be clearly seen even at a long distance or in a complex environment. The addition of the image sensor greatly enhances the intuitiveness and ease of use of the rangefinder. The display module receives the video signal transmitted by the image sensor and displays it, and sometimes superimposes the measurement data (such as distance, angle, etc.) to form an interface that integrates observation and measurement information. A ring-shaped target orientation display icon may also be integrated here to assist the user in understanding the orientation of the target.
[0120] The distance measurement module uses laser ranging technology to emit laser pulses to the target and receive the reflected pulses, and calculates the straight-line distance between the target and the rangefinder based on the speed of light and the round-trip time. This process is fast and accurate and is suitable for measurements within a variety of distance ranges.
[0121] Angle measurement modules generally use electronic tilt compensation technology or built-in tilt sensors (such as gyroscopes or accelerometers) to measure the tilt angle of the rangefinder itself, thereby calculating the target angle relative to the horizontal or vertical plane. This is particularly important for measuring targets that are not in the same plane or height, and can provide more comprehensive three-dimensional spatial measurement data.
[0122] Exemplarily, the image sensor may be a visible light image sensor, an infrared image sensor, an ultraviolet image sensor, etc., which is not specifically limited herein.

[0126] The control module 130 is configured to compare the measurement angle corresponding to the second measurement distance with the first measurement angle. If the measurement angle corresponding to the second measurement distance is equal to the first measurement angle, it indicates that the position of the target object has been locked.
