Description

Technical Field

[0001] This utility model relates to the field of visual enhancement imaging technology, and in particular to a visual enhancement lens adjustment structure with zoom and position adjustment functions. Background Technology

[0002] As a non-contact measuring instrument, the visual enhancement imaging system captures video images of the object being measured and then uses patented algorithm enhancement technology to amplify micro-vibrations to a level visible to the naked eye. Its interface functions like it has millions of displacement sensors, with each pixel capable of collecting vibration data. By selecting a location of interest, vibration data for that point can be obtained, such as waveforms, spectra, and axis trajectories.

[0003] Currently, when using visual augmentation imaging systems for equipment vibration detection, a data acquisition device and lens must be set up in advance, with the lens mounted on the data acquisition device. Existing visual augmentation imaging systems mostly use fixed focal length lenses of 12.5mm, 25mm, 50mm, and 100mm. When setting up the data acquisition device, the straight-line distance from the lens to the object being measured must be precisely selected, and a lens with an appropriate focal length must be matched to ensure that the device being filmed is fully displayed in the video interface. After completing the overall imaging of the device under test, local video images of the area of ​​interest also need to be captured for local analysis.

[0004] When using existing fixed-focal-length lenses, it is necessary to manually select the appropriate focal length and adjust the distance between the lens and the device under test based on the size and distance of the device being tested. This process is cumbersome, requires a high level of experience from the operator, and in actual testing scenarios, if multiple devices of different sizes and distances are encountered, frequent lens changes and distance adjustments will consume a lot of time and effort, seriously affecting testing efficiency.

[0005] The existing system cannot adjust the lens direction based on the position of the device under test (DUT) in the video frame. When the position of the DUT changes, the lens direction and position need to be manually readjusted to ensure that the DUT is always centered in the frame and the image is clear, which increases the complexity and instability of the operation.

[0012] Preferably, the vertical multi-functional adjustment structure includes four independent electro-hydraulic cylinders installed at the four corners of the top of the two-dimensional moving base, and the telescopic rods of the electro-hydraulic cylinders are hinged to the bottom end of the adjustment platform.

[0013] Preferably, the two-dimensional horizontal moving mechanism includes a horizontal moving structure and a vertical moving structure arranged vertically, and the horizontal moving structure and the vertical moving structure are staggered in the vertical direction.

[0014] Preferably, the lateral movement structure includes lateral movement sliders symmetrically arranged on both sides of the two-dimensional moving frame, and lateral sliding grooves adapted to the lateral movement sliders are provided on both sides of the two-dimensional moving frame. The lateral movement sliders are inserted into the lateral sliding grooves and slidably connected to the lateral sliding grooves.

[0015] Preferably, a horizontal movement motor is provided on the horizontal movement slider on one side of the two-dimensional moving frame.

[0033] Example

[0034] like Figure 1 As shown, the present invention discloses a visual enhancement lens adjustment structure with zoom and position adjustment functions, including a visual enhancement camera 1 with an auto-zoom lens. The visual enhancement camera 1 uses an existing camera structure and is wirelessly connected to a host computer, transmitting the acquired image data to the host computer for analysis, processing, and storage. Its auto-zoom lens adopts an existing auto-zoom lens structure, with a front fixed group, a zoom group, a compensation group, and a rear fixed group arranged sequentially along the optical axis from the object side to the image side. The front fixed group includes at least one meniscus positive lens and a biconvex lens for preliminary correction of spherical aberration and coma. The zoom group includes at least one aspherical negative lens and an aspherical positive lens, changing the focal length through linear movement. The compensation group compensates for the image plane position during zooming to ensure consistent image clarity. The rear fixed group performs final correction and convergence of the light, improving image quality. The auto-zoom lens structure includes an autofocus module, which includes an image sensor, a focus control unit, and driving elements. The image sensor acquires image information from the device under test in real time and transmits it to the focus control unit. The focus control unit analyzes image characteristics such as sharpness to calculate the deviation between the current lens focal length and the optimal focal length, and then sends a control signal to the drive element. Based on the received signal, the drive element precisely adjusts the positions of the lenses in the zoom and compensation groups, achieving automatic adjustment of the lens focal length and ensuring that the device under test maintains a clear image in the video feed.

[0035] The visual intensifier camera 1 is mounted on a detachable mounting platform 2, which is connected to the multi-functional platform via bolts and nuts, facilitating the installation and removal of different visual intensifier cameras 1. The outer side of the multi-functional platform is connected to the two-dimensional moving base 10 via a vertical multi-functional adjustment structure with height, pitch, and tilt angle adjustments. The middle of the multi-functional platform is connected to the two-dimensional moving base 10 via a self-rotating structure.

[0036] like Figure 2 As shown, the multi-functional platform includes a centrally located rotating frustum 3. The outer surface of the rotating frustum 3 is connected to an adjustment platform 5 via bearings 4. The visual enhancement camera 1 is located on the rotating frustum 3. Figure 3As shown, the self-rotating structure includes a rotary motor 6, the output shaft of which is connected to the bottom end of the rotating frustum 3. The bottom end of the rotary motor 6 is connected to a universal ball joint support 8 via a telescopic column 7. The universal ball joint support 8 is located at the top of the two-dimensional moving base 10. The vertical multi-functional adjustment structure includes four independent electric hydraulic cylinders 9 installed at the four corners of the top of the two-dimensional moving base 10. The telescopic rods of the electric hydraulic cylinders 9 are hinged to the bottom end of the adjustment platform 5.

[0037] Four independent electro-hydraulic cylinders 9 work together to raise and lower the adjustment platform 5, thereby raising and lowering the entire multi-functional platform and adjusting the height of the visual intensification camera 1. Two electro-hydraulic cylinders 9 located on the same side of the visual intensification camera 1 can adjust its horizontal tilt angle, and two electro-hydraulic cylinders 9 located at the same end of the visual intensification camera 1 can adjust its pitch angle. A rotary motor 6 drives a rotating platform 3 to rotate, which in turn causes the visual intensification camera 1 to rotate, adjusting its shooting direction. When the rotating platform 3 rotates, the adjustment platform 5 does not rotate due to the bearing 4. Raising and lowering the adjustment platform 5 moves the entire multi-functional platform; the telescopic column 7 can extend and retract, and the universal ball joint support 8 can rotate a wide range. The rotary motor 6 under the rotating platform of the multi-functional platform moves with the rotating platform under the action of the telescopic column 7 and the universal ball joint support 8. A position sensor is installed on the visual intensification camera 1 to monitor the position of the device under test.

[0038] The two-dimensional moving base 10 is connected to the two-dimensional moving frame 11 via a two-dimensional horizontal moving mechanism. The two-dimensional horizontal moving mechanism includes a vertically arranged lateral moving structure and a longitudinal moving structure, which are staggered in the vertical direction. The lateral moving structure includes lateral moving sliders 12 symmetrically arranged on both sides of the two-dimensional moving frame 11. Lateral grooves 13, adapted to the lateral moving sliders 12, are provided on both sides of the two-dimensional moving frame 11. The lateral moving sliders 12 are inserted into and slidably connected to the lateral moving grooves 13. A lateral moving motor 15 is mounted on the lateral moving slider 12 on one side of the two-dimensional moving frame 11. The output shaft of the lateral moving motor 15 is connected to one end of a lateral lead screw 14. The other end of the lateral lead screw 14 passes through the two-dimensional moving base 10 and is rotatably connected to the lateral moving slider 12 on the other side of the two-dimensional moving frame 11. The lateral lead screw 14 and the two-dimensional moving base 10 are connected by a thread. The longitudinal movement structure includes longitudinal movement sliders 17 symmetrically arranged on both sides of the two-dimensional moving frame 11. Longitudinal grooves 16, adapted to the longitudinal movement sliders 17, are provided on both sides of the two-dimensional moving frame 11. The longitudinal movement sliders 17 are inserted into and slidably connected to the longitudinal grooves 16. A longitudinal movement motor is mounted on the longitudinal movement slider 17 on one side of the two-dimensional moving frame 11. The output shaft of the longitudinal movement motor is connected to one end of a longitudinal lead screw 18. The other end of the longitudinal lead screw 18 passes through the two-dimensional moving base 10 and is rotatably connected to the longitudinal movement slider 17 on the other side of the two-dimensional moving frame 11. The longitudinal lead screw 18 and the two-dimensional moving base 10 are connected by threads.

[0039] The transverse moving motor 15 drives the transverse lead screw 14 to rotate, thereby causing the two-dimensional moving seat 10 to move laterally along the transverse lead screw 14. At this time, the longitudinal moving motor and the longitudinal lead screw 18 move laterally in the longitudinal slide groove 16 through the longitudinal moving slider 17. The longitudinal moving motor drives the longitudinal lead screw 18 to rotate, thereby causing the two-dimensional moving seat 10 to move laterally along the longitudinal lead screw 18. At this time, the transverse moving motor 15 and the transverse lead screw 14 move laterally in the transverse slide groove 13 through the transverse moving slider 12, thereby realizing the transverse and longitudinal movement of the two-dimensional moving seat 10, and thus driving the visual enhancement camera 1 to move in the two-dimensional horizontal direction.

[0040] The two-dimensional moving frame 11 is detachably connected via a fixed structure. The fixed structure includes a shock-absorbing rubber pad 19. The two-dimensional moving frame 11 is connected to a fixed frame (including the ground, tripod, etc.) via the shock-absorbing rubber pad 19. The shock-absorbing rubber pad 19 is located between the two-dimensional moving frame 11 and the fixed frame. The two-dimensional moving frame 11, the shock-absorbing rubber pad 19, and the fixed frame are locked together with bolts and nuts. The shock-absorbing rubber pad 19 is made of highly elastic, high-damping rubber material, and its shape and size are customized according to the connection points of the fixed structure. The upper and lower surfaces of the rubber pad are tightly fitted to the bottom of the two-dimensional moving frame and the fixed frame, respectively. The elastic deformation of the shock-absorbing rubber pad 19 absorbs and buffers external vibrations, reducing the transmission of vibrations to the camera. Simultaneously, small shock-absorbing rubber pads 19 are also installed in key components inside the lens, such as between the lens assembly and the camera housing. These small shock-absorbing rubber pads 19 further isolate the lens from minute displacements and shakes caused by external vibrations, ensuring lens stability during shooting and improving image quality.

[0041] In use, the position sensor monitors the visual enhancement camera 1, and the image captured by the camera is sent to the host computer. The host computer then controls the horizontal and vertical motors to move the two-dimensional moving base 10 on the two-dimensional moving frame 11. The electric hydraulic cylinder 9 drives the multi-functional platform to adjust its lifting, tilting, and pitch. With the help of the automatic zoom lens, the device under test is always clearly imaged in the video frame of the visual enhancement camera 1.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
