[0029] The purpose of the present application is to overcome the above technical deficiencies, and provide a visual displacement device to solve the technical problems of complex structure, large volume and high cost in the prior art.

[0030] To achieve the above technical purpose, the present application adopts the following technical scheme:

[0031] As shown in Figure 1 The present application provides a visual displacement device, which comprises a base support 1, a displacement measurement unit 2, an optical imaging unit 3 and a data processing unit.

[0032] The base support 1 is made of high-strength aluminum alloy or carbon fiber composite material, which has good rigidity and stability, effectively suppressing the influence of environmental vibration on measurement. At the same time, by anodizing the surface of the support, the structural stability during long-term use is ensured.

[0033] The displacement measurement unit 2 comprises a displacement platform 21, an adjusting mechanism and a drive controller 22. The displacement platform 21 is arranged on the base support 1, the adjusting mechanism is arranged on the displacement platform 21, and the drive controller 22 is signal connected with the displacement platform 21 and the adjusting mechanism respectively. After the device is started, the drive controller 22 drives the adjusting mechanism to initialize the relative position between the displacement platform 21 and the optical imaging unit 3, so as to ensure that they are in the initial position. Then the drive controller 22 drives the displacement platform 21 to move the position of the optical imaging unit 3, so that the optical imaging unit 3 collects multiple images of the target object at different positions. These images reflect the characteristics of the target object from different angles.

[0034] The optical imaging unit 3 is arranged on the adjusting mechanism. The optical imaging unit 3 collects multiple images of the target object at different positions, and the collected images are transmitted to the data processing unit through signal connection.

[0035] The data processing unit is in signal connection with the driving controller 22 and the optical imaging unit 3 respectively, and is used for analyzing the image to obtain the size of the target object. After receiving the image, the data processing unit analyzes a plurality of images by using an image processing algorithm to extract feature points, edges and other information of the target object. Based on the analysis result, the data processing unit calculates the size of the target object, including length, width, height and other parameters. The final calculation result can be output through a display interface or a data interface for the user to view or further process.

[0036] The present application divides the device into a plurality of independent functional units through modular design, and each unit has a clear functional definition. The optical imaging unit 3 collects a plurality of images of the target object at different positions by moving the optical imaging unit 3 through the displacement measurement unit 2, and the data processing unit analyzes the size of the target object based on the plurality of images. This design greatly reduces the number and complexity of parts, making the assembly and debugging process of the system more convenient and fast. Modular design allows flexible selection and combination of corresponding modules according to the needs of different application scenarios. Modular design is conducive to standardization of production and improves production efficiency. At the same time, due to the universality and simplicity of parts, the manufacturing cost is reduced, and the system has stronger competitiveness in the market.

[0037] The modular design concept of the present application makes the system have strong adaptability. The base support 1 can be made of carbon fiber composite material to realize lightweight; the imaging unit can select a face array or a line array camera according to the needs; the displacement platform 21 can be equipped with different strokes; and the data processing unit reserves a plurality of communication interfaces. This flexible design allows the system to be optimized according to the specific application scenario.

[0038] In some embodiments of the present application, the displacement platform 21 includes a first linear guide rail, and the optical imaging unit 3 is in sliding connection with the first linear guide rail through the adjusting mechanism.

[0039] The optical imaging unit 3 is in sliding connection with the first linear guide rail through the adjusting mechanism and can be accurately moved under the drive of the linear motor. The displacement platform 21 moves according to the preset path and speed, so that the optical imaging unit 3 collects a plurality of images of the target object at different positions. The first linear guide rail provides stable sliding connection, reduces vibration and error during movement, and improves the stability of measurement.

[0040] The displacement platform 21 driven by high-precision linear motors and combined with precise control systems achieves a repeat positioning accuracy of ±1 μm, ensuring high accuracy of measurement results. The standard stroke is 100 mm, which can be extended to 200 mm or 300 mm as needed to adapt to the measurement needs of target objects of different sizes. The high-precision linear motor drive and precise control system enable the displacement platform 21 to move quickly and accurately, improving the efficiency of image acquisition and processing.

[0041] In some embodiments of the present application, the displacement platform 21 further comprises a motor and an encoder, the motor being in transmission connection with the adjusting mechanism, and the encoder being in signal connection with the motor and the drive controller 22, respectively.

[0042] The drive controller 22 controls the motor operation through the built-in proportional-integral-derivative (PID) algorithm according to the preset displacement parameters, achieving fast and smooth movement of the displacement platform 21. The encoder monitors the rotation angle of the motor and the position of the optical imaging unit 3 on the displacement platform 21 in real time, and feeds back the position information to the drive controller 22 to form a closed-loop control. When the displacement platform 21 reaches the preset target position, the drive controller 22 sends a signal to trigger the optical imaging unit 3 to take a picture, ensuring accurate synchronization of displacement and image acquisition.

[0043] The drive controller 22 with built-in PID algorithm achieves fast and smooth displacement control, improving the positioning accuracy of the displacement platform 21. The optical imaging unit 3 is triggered to take a picture after the displacement platform 21 reaches the target position, ensuring accurate synchronization of displacement and image acquisition and improving measurement accuracy. The optional air floating guide rail replaces the linear guide rail, greatly reducing friction error and further improving measurement accuracy. The signal connection of the encoder with the motor and the drive controller 22 realizes closed-loop control, enhancing the stability and reliability of the system.

[0044] In some embodiments of the present application, the adjusting mechanism comprises a correction module 23, the correction module 23 comprising a second linear guide rail, a third linear guide rail, and a fourth linear guide rail, the second linear guide rail being provided on the displacement platform 21, the third linear guide rail being in sliding connection with the second linear guide rail, and the fourth linear guide rail being in sliding connection with the third linear guide rail and the optical imaging unit 3, respectively.

[0045] Through the cooperation of the second linear guide rail, the third linear guide rail, and the fourth linear guide rail, the optical imaging unit 3 can be independently fine-tuned in X, Y, and Z directions. Each linear guide rail allows precise displacement in its axial direction, enabling fine adjustment of the position of the optical imaging unit 3. The optical imaging unit 3 can be accurately positioned to the best measurement position. This position can maximize measurement accuracy, reduce error, and ensure the reliability of measurement results.

[0046] Multi-axis fine-tuning and angular adjustment capabilities ensure that the optical imaging unit 3 can be precisely aligned with the measurement target, enabling high-precision displacement measurement. Supporting multi-directional and multi-angle adjustments allows the system to adapt to measurement objects of different shapes, sizes, and positions, enhancing the system's flexibility and adaptability. Through precise position and angle adjustments, measurement errors caused by equipment installation or environmental factors can be minimized.

[0047] In some embodiments of the present application, the correction module 23 further comprises a correction motor assembly, the second linear guide, the third linear guide, and the fourth linear guide are perpendicular to each other, and the correction motor assembly is drivingly connected with the third linear guide, the fourth linear guide, and the optical imaging unit 3, respectively.

[0048] Each motor independently controls the movement of one linear guide, achieving precise displacement in X, Y, and Z directions. The perpendicular layout forms displacement adjustment capability in three-dimensional space. This layout ensures that displacement in each direction is independent and does not interfere with each other.

[0049] The correction motor assembly receives instructions from the drive controller 22, and through precise control of the rotation angle and speed of the motor, achieves precise displacement of the linear guide. At the same time, the encoder on the motor feeds back position information in real time, forming a closed-loop control, ensuring the accuracy and stability of displacement. When multiple direction adjustments are needed at the same time, the drive controller 22 can coordinate the work of multiple correction motor assemblies to achieve synchronous adjustment and quickly position the optical imaging unit 3 to the best measurement position.

[0050] Through the independent driving and vertical layout design of the correction motor assembly, high-precision positioning in three-dimensional space is achieved, significantly improving the measurement accuracy. Multi-axis independent driving allows the system to flexibly adjust in X, Y, Z directions and angles, adapting to various complex measurement requirements. Closed-loop control and real-time feedback of motor encoders ensure the stability and reliability of displacement, reducing measurement errors.

[0051] In some embodiments of the present application, the adjustment mechanism comprises a gimbal module 24, the gimbal module 24 comprising a horizontal rotation axis, a vertical pitch axis, and a support assembly, the support assembly being drivingly connected with the horizontal rotation axis, the vertical pitch axis, and the optical imaging unit 3, respectively.

[0052] The horizontal rotation axis allows the optical imaging unit 3 to rotate 360 degrees in the horizontal direction, while the vertical pitch axis allows pitch movement in the vertical direction. The support assembly is in transmission connection with the horizontal rotation axis, the vertical pitch axis, and the optical imaging unit 3, respectively, ensuring the stability of the gimbal module 24 and the accuracy of angle adjustment. By controlling the movement of the gimbal module 24 through the drive controller 22, the optical imaging unit 3 can be accurately adjusted to the optimal measurement angle to obtain the clearest and most accurate image. When displacement and angle adjustment are required simultaneously, the drive controller 22 can coordinate the work of the gimbal module 24 and the displacement platform 21, achieving synchronous control and ensuring the continuity and accuracy of the measurement process.

[0053] The design of the gimbal module 24 allows the optical imaging unit 3 to measure at multiple angles, adapting to targets of different shapes and positions, improving the flexibility and adaptability of measurement. Through precise transmission and control mechanisms, the gimbal module 24 can achieve high-precision angle positioning, ensuring the accuracy of measurement results. The fast and precise angle adjustment capability reduces the preparation time before measurement, improving the measurement efficiency.

[0054] In some embodiments of the present application, the gimbal module 24 includes one of a gimbal motor assembly, a hydraulic assembly, and a pneumatic assembly, which are in transmission connection with the horizontal rotation axis and the vertical pitch axis, respectively.

[0055] According to specific application requirements, the gimbal module 24 can choose a gimbal motor assembly, a hydraulic assembly, or a pneumatic assembly as a power source. These power assemblies are in transmission connection with the horizontal rotation axis and the vertical pitch axis, respectively, providing the necessary rotation and pitch power.

[0056] By controlling the rotation angle and speed of the gimbal motor assembly, or adjusting the pressure and flow of the hydraulic / pneumatic assembly, the optical imaging unit 3 can be accurately adjusted in the horizontal and vertical directions. The support assembly ensures the stability of the gimbal module 24 during movement, reduces vibration and deviation, and ensures measurement accuracy.

[0057] The drive controller 22 coordinates the work of the power assembly of the gimbal module 24 and the displacement platform 21, achieving synchronous control of displacement and angle adjustment, ensuring the continuity and accuracy of the measurement process.

[0058] The gimbal motor, hydraulic and pneumatic power options are provided to adapt to different environments and application requirements, enhancing the flexibility and adaptability of the system. Regardless of the power component used, high-precision angle adjustment can be achieved to ensure that the optical imaging unit 3 is always at the optimal measurement angle. Through stable support and precise transmission design, vibration and uncertainty during measurement are reduced, improving the stability and reliability of the system. The fast and precise angle adjustment capability reduces the preparation time before measurement, improving the measurement efficiency.

[0059] In some embodiments of the present application, the optical imaging unit 3 includes an industrial camera and a ring light source, the industrial camera is connected with the adjustment mechanism, and the ring light source is arranged on the periphery of the industrial camera.

[0060] The industrial camera uses a global shutter CMOS sensor. As the core component, it is responsible for capturing the image of the target object. The camera uses high-resolution global shutter technology, which can capture clear and non-smear images in high-speed motion state. The ring light source is arranged around the camera to provide uniform and stable illumination, ensuring image quality.

[0061] The industrial camera is connected with the displacement platform 21 through the adjustment mechanism, and can be fine-tuned in X, Y, Z three directions and angle, to ensure that the camera is always aligned with the target object and is in the best measurement position. The drive controller 22 coordinates the work of the displacement platform 21, the correction module 23 and the optical imaging unit 3, to realize the synchronous control of displacement, angle adjustment and image acquisition.

[0062] The high-resolution camera with 2048x1536 pixels ensures the clarity and detail performance of the image, providing a foundation for accurate measurement. The high-speed frame rate of 120fps enables the camera to capture each frame of image in high-speed motion state, avoiding smearing and blurring, and improving the accuracy and efficiency of measurement. The ring light source provides uniform and shadow-free illumination, reducing image shadows and reflections, enhancing image quality and measurement reliability.

[0063] In some embodiments of the present application, the ring light source includes a light source controller and a plurality of light zones, each of the light zones includes a plurality of lamp beads, and each of the light zones is individually signal connected with the light source controller.

[0064] Each light zone is connected with the light source controller through a separate signal line to realize independent control. The system is equipped with an ambient light sensor to detect the lighting conditions of the measurement environment in real time. The light source controller automatically adjusts the brightness of each light zone according to the feedback of the ambient light sensor. Through zoning control, fine adjustment can be made according to the lighting needs of different areas to optimize the overall imaging quality.

[0065] The system automatically adjusts brightness based on ambient light, ensuring ideal imaging results under varying lighting conditions. Zoned control allows for independent brightness adjustment of each light zone, enhancing the flexibility and targeted nature of lighting. Automatic brightness adjustment reduces overexposure and underexposure, improving image sharpness and detail. Stable and uniform lighting conditions help reduce image noise and interference, improving measurement accuracy and reliability. Adjusting brightness according to actual needs avoids unnecessary energy waste, achieving energy-efficient operation.

[0066] In some embodiments of this application, the data processing unit includes an image processing chip and a host computer.

[0067] Image data acquired by optical imaging unit 3 is transmitted to image processing chip via signal connection. The image processing chip uses a 2.0GHz industrial-grade embedded processor to efficiently process the acquired image data, including preprocessing, feature extraction, and size calculation. The image processing chip communicates with the host computer in real time via Ethernet interface, transmitting the processed data to the host computer for further analysis or display. Based on the received data, the host computer controls the drive controller 22 and optical imaging unit 3 in real time via signal connection, adjusting parameters such as the position of displacement platform 21 and light source brightness. The system reserves multiple communication interfaces such as CAN and RS485 for future expansion or integration with other devices.

[0068] A 2.0GHz industrial-grade embedded processor and built-in high-efficiency image processing algorithms ensure fast and accurate image data processing. An Ethernet interface enables real-time communication between the image processing chip and the host computer, guaranteeing the system's real-time performance. Multiple reserved communication interfaces facilitate system expansion and integration with other devices, enhancing system flexibility. The industrial-grade embedded processor and stable communication interfaces ensure stable operation in complex industrial environments. The system design supports future functional expansion, adapting to evolving needs.

[0069] After the system starts up, it first performs a self-test process to check the status of each hardware component and software module to ensure that the system is fault-free. The self-test time is controlled within 30 seconds to improve startup efficiency.

[0070] In a stable environment of 23±2℃, the light source is preheated for no less than 5 minutes to eliminate the impact of light source brightness fluctuations on image quality and ensure the stability and consistency of imaging.

[0071] Three camera calibrations were performed using a 9×9 calibration plate to accurately correct camera intrinsic parameters and distortion, ensuring the accuracy and reliability of the measurement results.

[0072] Depending on the measurement requirements, the sampling frequency can be adjusted from 10Hz to 1kHz to adapt to measurement tasks of different speeds and accuracies.

[0073] The image processing chip efficiently processes the acquired image data and controls the data processing and output latency to within 10ms, ensuring the system's real-time performance and response speed.

[0074] Let the pixel coordinates of the target point in the two shots be P1 and P2, then the pixel displacement ΔP = P2 − P1. Given the physical displacement D of the optical imaging unit 3 (e.g., 100 mm), establish the proportional relationship using the principle of similar triangles:

[0075] Actual size = (D / ΔP) × Δp_target

[0076] Here, Δp_target represents the pixel difference corresponding to other parts of the target in the image. This allows the pixel difference to be converted into actual size.

[0077] Optimized rapid self-test and light source preheating processes significantly shorten system startup time and improve measurement efficiency. Environmental control and light source preheating design effectively ensure the stability and consistency of image quality, improving measurement accuracy. Multiple camera calibrations ensure precise correction of camera parameters, eliminating system errors and enhancing measurement precision.

The displacement platform 21 achieves precise motion control through motors and encoders, while the optical imaging unit 3 acquires image data of the target object. The middle layer performs image processing and displacement calculation. The image processing chip performs preprocessing, feature extraction, and size calculation on the acquired image data and transmits the results to the upper layer. The upper layer implements the user interface and data management functions. The host computer provides a user interface, displays measurement results, and manages data storage, transmission, and system settings.

[0079] An industrial camera, in conjunction with a ring light source, captures clear, motion-free images, ensuring accurate data acquisition. The drive controller 22 incorporates a PID algorithm to achieve fast and precise displacement control, guaranteeing synchronization between image acquisition and displacement. Efficient image processing algorithms and real-time communication ensure the speed and accuracy of data processing, meeting real-time requirements. The optical imaging, displacement control, and data processing stages work closely together to form an efficient and precise measurement process.

[0080] The layered architecture clearly defines system functions, reducing interference between modules and improving system stability and reliability.
