[0047] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0048] First, see Figure 1-8 The present invention discloses a long sniper scope 1, which can be installed on firearms such as long sniper rifles to assist aiming and shooting.

[0049] The long sniper scope 1 includes a shell 11, an adjusting gear 12, an objective lens module 13, and an eyepiece lens module 14. The objective lens module 13 and the eyepiece lens module 14 are installed in the shell 11, and the adjusting gear 12 is arranged between the objective lens module 13 and the eyepiece lens module 14. The adjusting gear 12 is connected to the shell 11, and the adjusting gear 12 is installed in the middle of the shell 11, and the adjusting gear 12 is connected to the objective lens module 13.

[0050] The objective lens module 13 includes a gear barrel 131 and a connecting member 132. The connecting member 132 is used to connect the lens and other auxiliary components of the objective lens module 13. The adjusting gear 12 and the connecting member 132 are respectively installed at the two ends of the gear barrel 131. The gear barrel 131 is sleeved on the outside of the connecting member 132. The adjusting gear 12 is meshed and connected with the circumferential side end of the gear barrel 131. The inner wall of the gear barrel 131 is connected to the outer wall of the connecting member 132. The inner wall of the other end of the gear barrel 131 and the outer wall of the connecting member 132 are provided with a first threaded structure 1321 that matches each other.

[0051] Specifically, the connecting member 132 is divided into a first connecting portion and a second connecting portion. The first connecting portion is configured as a cylinder, and the second connecting portion is configured as a trumpet. The first connecting portion and the second connecting portion are integrally formed, and the outer wall of the first connecting portion is provided with a first thread structure 1321. The outer wall of the gear barrel 131 contacts the inner wall of the housing 11, and the outer wall of the connecting member 132 contacts the inner wall of the gear barrel 131. The gear barrel 131 is sleeved with the connecting member 132. A rotating tooth pattern 1311 is circumferentially provided on one end of the gear barrel 131. The tooth pattern on the adjusting gear 12 matches the rotating tooth pattern 1311. The rotating tooth pattern 1311 surrounds the edge of one end of the gear barrel 131. The adjusting gear 12 is meshed with the rotating tooth pattern 1311. The adjusting gear 12 rotates to drive the gear barrel 131 to rotate. The gear barrel 131 and the connecting member 132 move relative to each other through the first thread structure 1321. Therefore, the operator can move the connecting member 132 and the lens on the connecting member 132 by rotating the adjusting gear 12.

[0052] Optionally, the rotating tooth pattern 1311 of the gear barrel 131 is set to an arc shape or a circle. When the rotating tooth pattern 1311 of the gear barrel 131 is set to an arc shape, that is, a circle on the edge of one end of the gear barrel 131 is not continuously covered with the rotating tooth pattern 1311, and limiters are set at both ends of the rotating tooth pattern 1311, the adjustment gear 12 is engaged with the rotating tooth pattern 1311, and the adjustment gear 12 is rotated, the gear barrel 131 rotates, and the rotation range is limited by the path of the rotating tooth pattern 1311, which can be used for smaller adjustments; when the rotating tooth pattern 1311 is set to a circle, the rotation range of the gear barrel 131 is not limited, and it can rotate continuously, and even rotate for multiple circles.

[0053] It can be understood that a gear barrel 131 and a connecting member 132 are provided in the objective lens module 13. One end of the gear barrel 131 is meshed with the adjusting gear 12, and the other end is connected to the connecting member 132. The adjusting gear 12 is inserted from the outside of the housing 11 and connected to the gear barrel 131. The operator can rotate the gear barrel 131 by rotating the adjusting gear 12, thereby driving the connecting member 132 to rotate. The connecting member 132 and the gear barrel 131 are connected by a threaded structure. The two rotate relative to each other, allowing the connecting member 132 to move in the housing 11, thereby allowing the objective lens 133 on the objective lens module 13 to move, thereby achieving the purpose of focusing the objective lens. Since the existing focusing structure is arranged at the front end of the objective lens, the operator needs to reach forward to make adjustments. Adjustment at the front end of the objective lens can easily cause the image obtained by the lens to vibrate and affect the accuracy of focusing. The adjusting gear 12 is installed in the middle of the housing 11. When the operator adjusts the adjusting gear 12, it is possible to avoid reaching the front end of the objective lens to make adjustments, thereby reducing the movement of shaking the objective lens 133, preventing vibration, and ensuring the accuracy of aiming.

[0054] The housing 11 includes an objective portion 111, an eyepiece portion 112 and an adjustment portion 113. The objective portion 111, the adjustment portion 113 and the eyepiece portion 112 are connected in sequence. The adjustment gear 12 is installed in the adjustment portion 113. The adjustment gear 12 is inserted into the interior of the housing 11 from the adjustment portion 113 and contacts the gear barrel 131. The objective lens module 13 is installed in the objective portion 111, and the eyepiece lens module 14 is installed in the eyepiece portion 112.

[0055] The adjustment portion 113 is further provided with a mounting portion 1131, and a mounting structure for mounting on a firearm can be provided on the mounting portion 1131. When the mounting portion 1131 is installed on the firearm, the adjustment gear 12 is located at the side, which is more conducive to the operator's rotation and adjustment action, avoiding directly rotating the adjustment structure on the objective lens 133 at the objective lens position, and improving the stability during focusing.

[0056] As an embodiment, the objective lens portion 111 , the adjustment portion 113 and the eyepiece portion 112 are integrally formed.

[0057] The objective lens portion 111 is provided with a mounting position 1111 , and the gear barrel 131 is fixedly mounted in the mounting position 1111 . The length of the mounting position 1111 is equal to the length of the gear barrel 131 .

[0058] A limiting portion 1312 is provided at one end of the gear barrel 131 connected to the connecting member 132, and the outer diameter of the limiting portion 1312 is smaller than that of other parts of the gear barrel 131. A limiting member 1112 is provided on the objective lens portion 111, and the outer diameter of the limiting member 1112 is the same as the inner diameter of the mounting position 1111. The inner diameter of the limiting member is the same as the outer diameter of the limiting portion 1312. A second thread structure 1113 matching each other is provided on the outer periphery of the limiting member 1112 and the inner wall of the mounting position 1111. When the gear barrel 131 is installed in the housing 11, First, put the gear barrel 131 into the installation position 1111, and then move the limiting piece corresponding to the second thread structure 1113 toward one end of the installation position 1111, so that the gear barrel 131 is fixedly installed in the installation position 1111. When the adjusting gear 12 drives the gear barrel 131 to rotate, the gear barrel 131 rotates in the installation position 1111 due to the limitation of the outer shell 11, and the connecting piece 132 and the gear barrel 131 move relative to each other through the first thread structure 1321.

[0059] The objective lens module 13 includes an objective lens 133, a distance measuring unit 134, and a dual filter assembly 135. The objective lens 133 and the distance measuring unit 134 are installed at one end of the connecting member 132, and the gear cylinder 131 is installed at the other end of the connecting member 132. The dual filter assembly 135 connects the objective lens 133 and the connecting member 132 respectively.

[0060] Among them, the objective lens 133 is used to obtain the observed scene, and the distance measuring unit 134 is used to measure the distance of the specific object that has been aimed. The distance measuring unit 134 uses laser distance measurement, and the dual filter component is an IR-CUT dual filter switcher, which is used to switch the night / day mode. In response to the black and white scene with changing light intensity, it can automatically switch according to the intensity of the external light to achieve the best image effect. The dual filter component 135 is arranged between the objective lens 133 and the connecting piece 132. The image observed by the objective lens is obtained from the objective lens 133. The dual filter component 135 can improve the clarity of the observed image. The distance measuring unit 134 detects the distance of the observed object through laser distance measurement, so that the operator can know the distance of the currently observed object.

[0061] The distance measuring unit 134 and the objective lens 133 are both provided in the objective lens part 111 and installed in the housing 11, so that the distance measuring unit 134 and the objective lens 133 are integrated at one end of the objective lens of the sight. Through the cooperation of the distance measuring unit 134, the focusing accuracy is improved, and the overall volume of the sight is reduced, and the appearance is more streamlined. Furthermore, through the control circuit inside the distance measuring unit 134, the objective lens 133 is used at the same time to form a dual-lens mode, realize the dual-lens far and near focusing mode, and the focusing function is stronger.

[0062] The housing 11 includes a rotating adjustment member 114, which is installed on the eyepiece part 112. The eyepiece lens module 14 includes a rotating gear 141 and an electronic magnification adjustment unit 142. The rotating gear 141 is connected to the electronic magnification adjustment unit 142, the rotating gear 141 is inscribed in the rotating adjustment member 114, and the outer surface of the rotating gear 141 is in contact with the inner wall of the rotating adjustment member 114.

[0063] Specifically, the rotating adjustment member 114 is installed outside the housing 11. The rotating adjustment member 114 is set to a circular ring shape, and an adjustment tooth pattern 1141 is set on the inner wall. The tooth pattern on the outer periphery of the rotating gear 141 matches the adjustment tooth pattern 1141. The outer diameter of the rotating gear 141 is smaller than the inner diameter of the rotating adjustment member 114. The outer periphery of the rotating gear 141 moves along the inner periphery of the rotating adjustment member 114. The electronic magnification adjustment unit 142 is fixedly arranged on the eyepiece part 112. The rotating gear 141 is connected to the encoder in the electronic magnification adjustment unit 142. The operator rotates the rotating adjustment member 114 to rotate the rotating gear 141. The encoder sends a corresponding electrical signal corresponding to the rotation direction and rotation amplitude of the rotating gear 141, so that the cross mark on the image displayed on the screen of the eyepiece lens module 14 is enlarged or reduced.

[0064] In addition, the eyepiece portion 112 is provided with an eyepiece focusing structure 1121, and the focal length of the eyepiece lens can be adjusted by rotating the eyepiece focusing structure 1121, so that the operator can observe the image on the screen more clearly.

[0065] The long sniper scope 1 includes a control module 15, and the control module 15 is respectively connected to the eyepiece lens module 14 and the objective lens module 13. Specifically, the control module 15 receives the observation image obtained by the objective lens module 13, and transmits the observation image to the eyepiece lens module 14 through an electrical signal, and the operator obtains the current observation image from the screen at the eyepiece lens module 14, that is, the control module 15 can transmit the image obtained at the objective lens module 13 to the eyepiece lens module 14 through an electrical signal.

[0066] The control module 15 includes a focusing unit 151, a communication unit 152, a processing unit 153, and a power supply unit 154. The processing unit 153 is connected to the focusing unit 151 and the communication unit 152 respectively, and the processing unit 153 is connected to the power supply unit 154.

[0072] Second, see Figure 9-10 The present invention discloses a ranging and aiming method, which is applied to any of the above-mentioned long sniper scopes, and specifically comprises the following steps:

[0073] Step S1: The distance measuring unit measures the real-time distance data and transmits it to the focusing unit in real time to obtain the best focal length value matching the real-time distance data;

[0074] Step S2: the focusing unit controls the movement of the objective lens according to the calculated optimal focal length value to complete the focal length adjustment;

[0075] Step S3: establishing a real-time two-way communication mechanism between the distance measuring unit and the focusing unit, integrating and fusing the information of the distance measuring unit and the focusing unit, dynamically coordinating the working states of the two modules, using the fused data to generate a more accurate focal length adjustment instruction, and the focusing unit performs a corresponding focusing operation according to the focal length adjustment instruction;

[0076] Step S4: According to the current environmental conditions and the state of the sight, an adaptive energy consumption control strategy is adopted to dynamically balance the ranging accuracy and energy consumption.

[0077] Specifically, in step S1, the current environmental condition parameters, such as temperature, humidity, light intensity and wind speed, are obtained through sensors, and it is determined whether the current environment is a harsh environment according to the preset environmental condition threshold. For example, in this embodiment, the preset environmental condition threshold can be set to a temperature below minus 10 degrees Celsius or above 40 degrees Celsius, humidity above 90%, light intensity below 100 lux, and wind speed greater than 10 meters per second. If the current environment is judged to be a harsh environment, the ranging frequency of the ranging unit is increased, and the ranging time is extended to obtain a higher ranging accuracy. If the current environment is judged to be an ideal environment, the ranging frequency of the ranging unit is reduced, and the ranging time is shortened, thereby reducing the energy consumption of the sight and extending the battery life. The high-precision distance data obtained by the ranging unit is transmitted to the focusing unit in real time, and the optimal focal length value matching the current target distance is obtained by calculation.

[0078] Specifically, in step S2, the focusing unit controls the objective lens to move in the housing according to the calculated optimal focal length value to complete the focal length adjustment, and simultaneously adopts a proportional integral differential control algorithm to minimize the vibration effect introduced in the focusing process.

[0079] Specifically, in step S3, a real-time two-way communication mechanism is established between the ranging unit and the focusing unit, and the Kalman filter algorithm is used to integrate and fuse the information of the ranging unit and the focusing unit, dynamically coordinate the working states of the two modules, and use the fused data to generate more accurate focal length adjustment instructions. The focusing unit performs corresponding focusing operations according to the focal length adjustment instructions.

[0080] Specifically, in step S4, according to the current environmental conditions and the state of the sight, an adaptive energy consumption control strategy is used to dynamically balance the ranging accuracy and energy consumption. For example, in a harsh environment, the power of the ranging unit is increased to 2w to ensure the aiming accuracy. In an ideal environment, the power of the ranging unit is reduced to 0.5w to extend the battery life.

[0081] It can be understood that the ranging unit detects the current distance data in real time, transmits the data to the focusing unit in real time, calculates the optimal focal length, and automatically adjusts the objective lens to make aiming more precise. In addition, an adaptive energy consumption control strategy is adopted according to environmental conditions to balance the ranging accuracy and the battery life of the sight, and dynamically coordinate the working status of the sight, so that the sight can accurately measure distance and intelligently focus in complex and changing environments, improving the adaptability and work efficiency of the sight.

[0082] Step S11: obtaining current environmental condition parameters including temperature, humidity, light intensity and wind speed, and determining whether the current environment is a harsh environment according to a preset environmental condition threshold;

[0083] Step S12: if the current environment is determined to be a harsh environment, the ranging frequency of the ranging unit is increased, and the time of each ranging is extended;

[0084] Step S13: if the current environment is determined to be an ideal environment, the ranging frequency of the ranging unit is reduced, and the time of each ranging is shortened;

[0085] Step S14: The high-precision distance data obtained by the distance measuring unit is transmitted to the focusing unit in real time, and the best focal length value matching the current target distance is calculated by least square fitting and Newton iteration method.

[0086] Specifically, in step S11, the sensor collects environmental parameters in real time, and uploads the acquired data to the cloud database through the wireless transmission module. The processing unit of the sight reads the preset threshold values ​​of various parameters from the database, and judges whether the various conditions are severe by comparing the magnitude relationship between the currently collected parameter values ​​and the corresponding threshold values. The processing unit adopts a logistic regression algorithm, takes parameters such as temperature, humidity, light intensity and wind speed as characteristic variables, and the severity as the target variable, and establishes a regression model through training sample data. The current parameter values ​​are input into the model for prediction to obtain a severity score. The scoring results and the determination results of the environment type will be written into the database for subsequent environmental status tracking and trend analysis. When it is determined that a severe environment occurs, the processing unit of the sight will automatically trigger an early warning, such as pushing an alarm message through a text message or an APP, and at the same time starting equipment protection measures, such as closing the external air circulation valve and increasing the heating power when using the sight indoors, to reduce the impact of the severe environment.

[0087] Specifically, in step S12, the severity index of the current environment is obtained, and the index is compared with the preset severity threshold. If it exceeds the threshold, it is judged as a harsh environment, otherwise it is judged as an ideal environment. According to the environmental judgment result, the ranging frequency parameter and the ranging time parameter of the ranging unit are dynamically set. If it is a harsh environment, the ranging frequency parameter is set to 10 times per second, and the ranging time parameter is set to 100 milliseconds; if it is an ideal environment, the ranging frequency parameter is set to 1 time per second, and the ranging time parameter is set to 10 milliseconds. The ranging frequency parameter and the ranging time parameter are transmitted to the ranging unit, and it is controlled to perform ranging operations at the set frequency and time, and the ranging result data returned by the ranging unit is received. Cluster analysis is performed on multiple ranging result data within a period of time, and the noise data with obvious deviations is eliminated to improve the accuracy of the ranging data. According to the power supply current and ranging frequency of the ranging unit, the energy consumption value per unit time is estimated, and the energy consumption value within a period of time is accumulated to calculate the energy consumption level of the ranging unit in the current environment. Get the current battery level, combine it with the energy consumption level in the previous step, and use the support vector machine regression algorithm to predict the remaining available time of the scope, that is, the endurance. Package the ranging accuracy, energy consumption level, endurance and other parameters and report them to the cloud monitoring platform to achieve real-time monitoring of ranging performance and energy consumption, and provide data support for further optimizing the ranging strategy.

[0088] Specifically, in step S14, the distance measuring unit adopts laser distance measuring technology to obtain high-precision target distance data. The target distance data obtained by the distance measuring unit is transmitted to the focusing unit in real time. After receiving the target distance data, the focusing unit uses it as an input parameter to establish a functional relationship model between the target distance and the optimal focal length value. The least squares method is used to fit the established functional relationship model to obtain a fitting function and related parameters. Based on the fitting function, the Newton iteration method is used to perform iterative calculation to obtain the optimal focal length value that matches the current target distance. The calculated optimal focal length value is transmitted to the lens control unit, and the servo motor of the lens is controlled to adjust the focal length to achieve intelligent focusing. The lens control unit determines whether the focal length of the current lens matches it according to the received optimal focal length value. If it does not match, the servo motor is controlled to make corresponding focal length adjustments until the focal length matching is completed.

[0089] Step S2 specifically includes the following steps:

[0090] The image information in the current environment is obtained, the key feature points in the image are extracted, and the clarity score of each feature point is calculated; according to the preset clarity threshold, whether the overall clarity of the current image meets the requirements is determined, if not, the intelligent focusing process is triggered; according to the position and clarity score of each feature point, an optimization objective function is constructed, and the optimal focal length value is solved by the gradient descent algorithm; the lens is controlled to move in the direction of the optimal focal length value, and the lens position is detected in real time, and the deviation between the current position and the optimal focal length position is calculated; the focal length deviation is used as the input of the PID controller, and the speed and acceleration of the lens movement are dynamically adjusted to make it move smoothly to the optimal focal length position; during the movement of the lens, the jitter of the device is detected in real time by the gyroscope, and the jitter signal is input into the PID controller for compensation to minimize the vibration introduced by the focusing process; after reaching the optimal focal length position, the clarity of the current image is evaluated. If the preset clarity requirements are met, the intelligent focusing process is completed, otherwise the above steps are repeated until the requirements are met.

[0091] It can be understood that the image information of the current environment is obtained through a high-resolution camera, the key feature points of the image are extracted using the SIFT algorithm, and the Laplacian gradient score of each feature point is calculated as its clarity. If the average clarity score of the image is lower than the preset threshold, intelligent focusing is triggered. According to the spatial distribution and clarity score of the feature points, a polynomial regression model is constructed as the optimization objective function, and the gradient descent algorithm is used to solve the optimal focal length value. The stepper motor is controlled to accurately adjust the lens position, and the position deviation is detected every time the predetermined distance is moved. The deviation is input into the PID controller to dynamically adjust the PWM output of the motor to make the lens move smoothly. At the same time, the gyroscope samples the angular velocity of the device at a predetermined frequency, compensates for the jitter in real time, and controls the vibration within 0-1°. After the focusing is completed, if the image clarity meets the requirements, it will exit, otherwise it will be optimized iteratively until it meets the standard. The whole process is completed within the preset time to ensure real-time focusing performance.

[0092] Step S3 specifically includes the following steps:

[0093] By establishing a real-time communication protocol, the data transmission between the ranging unit and the focusing unit is ensured to be delay-free and continuously updated, thereby ensuring the efficient operation of the two-way mechanism. In order to achieve real-time communication between the ranging unit and the focusing unit, the Socket communication method based on the TCP / IP protocol can be adopted. By establishing a dedicated high-speed network connection, the data transmission delay of the two modules can be controlled within 1 millisecond. At the same time, by setting the priority and cache mechanism of data transmission, the priority transmission and processing of key data can be ensured, thereby ensuring the stability and real-time performance of two-way communication.

[0094] The Kalman filter algorithm is used to fuse the distance data obtained from the distance measurement unit and the focus feedback of the focusing unit, and the accuracy and stability of the data are improved through algorithm optimization. In terms of data fusion, the Kalman filter algorithm can dynamically estimate and predict the distance data and focus feedback by establishing state equations and observation equations. The Kalman filter algorithm is used to synchronize and align the data of the two modules, and the weight coefficient is dynamically adjusted to achieve optimal data fusion.

[0095] According to the fused data, the working status of the two modules is dynamically adjusted to adapt to different shooting environments and object distances. According to the fused distance data and parameters such as ambient light intensity, the measurement frequency of the distance measurement unit and the focusing speed of the focusing unit are dynamically adjusted.

[0096] The optimized data is used to generate accurate focal length adjustment instructions, which are implemented by the focusing unit to achieve fast and accurate focus adjustment. In terms of focal length adjustment instruction generation, the fused distance data can be converted into corresponding focal length values ​​by establishing a distance-focal length mapping table, and corresponding control instructions, i.e., focal length adjustment instructions, are generated according to the characteristics of the focusing unit. The focusing unit performs corresponding focusing operations according to the control instructions to adjust the objective lens.

[0097] In addition, the scope will continuously monitor the focusing effect and adjust the Kalman filter parameters according to the actual imaging effect to further optimize the overall performance of the scope. In terms of focusing effect monitoring and feedback, the focusing effect can be evaluated in real time by analyzing indicators such as imaging clarity and contrast, and the parameters of the Kalman filter algorithm can be dynamically adjusted according to the evaluation results, such as the covariance matrix of measurement noise and process noise, to adapt to different shooting scenes and object characteristics, thereby achieving adaptive optimization and intelligent control of the entire autofocus process.

[0098] Step S4 specifically includes the following steps:

[0099] The current environmental condition data is obtained in real time through the environmental monitoring sensor, and the sensor data is transmitted to the processing unit through the data interface. The processing unit determines whether the current environment is a harsh environment or an ideal environment based on the preset environmental parameter threshold. If it is judged to be a harsh environment, the processing unit sends a command to the ranging unit to adjust the power to 2 watts to ensure high-precision aiming; if it is judged to be an ideal environment, the power is adjusted to 5 watts to extend the battery life of the device. In addition, the processing unit will dynamically adjust the energy consumption control strategy according to the real-time monitoring of the device's battery life status, optimize power usage, and ensure that the device can operate efficiently in different environments. Through this series of data processing and control instructions, precise control and energy consumption optimization of the ranging unit are achieved.
