Description

Technical Field

[0001] This utility model relates to the field of optical measurement target technology, and in particular to a 3D camera target orientation adjustment component with a self-locking function. Background Technology

[0002] A "3D camera target" refers to a physical target object specifically designed and manufactured for calibrating, testing, and validating the performance of 3D cameras (depth cameras). Unlike planar calibration boards (such as checkerboards) used for traditional 2D cameras, 3D camera targets typically have a defined three-dimensional geometry and known spatial dimensions to accurately assess the accuracy of the depth information acquired by the camera. 3D camera targets are a key tool for ensuring the accuracy and reliability of 3D camera measurement data. It is a physical reference with a precisely known three-dimensional geometry and specific surface properties, its core purpose being to calibrate camera parameters (especially depth parameters) and validate various performance indicators of the camera (accuracy, resolution, etc.). Choosing a suitable target is crucial to fully realizing the potential of a 3D camera. High-quality 3D camera targets are indispensable in fields such as industrial inspection, robot navigation, 3D reconstruction, and virtual reality / augmented reality.

[0003] Some existing 3D camera targets typically rely on manual operation or simple mechanical structures for orientation adjustment, making it difficult to achieve rapid locking and stable holding. Furthermore, the orientation may shift due to external forces or vibrations during the adjustment process, affecting the calibration accuracy of the 3D camera target. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing 3D camera targets, which usually rely on manual operation or simple mechanical structures for orientation adjustment, making it difficult to achieve rapid locking and stable holding. Furthermore, the orientation may be deviated due to external forces or vibrations during the adjustment process, affecting the calibration accuracy of the 3D camera target. This invention provides a 3D camera target orientation adjustment component with a self-locking function.

[0005] The purpose of this utility model is achieved through the following technical solution: A D-camera target direction adjustment component with self-locking function, including a base, an outer shell mounted on the base, an installation plate mounted inside the outer shell, a rotatable support column mounted on the installation plate, a section of the support column away from the installation plate extending out of the outer shell and mounting a target mounting plate, a servo motor mounted on the installation plate, a first gear mounted on the power output end of the servo motor, and a second gear meshing with the first gear mounted on the support column;

[0006] The mounting plate is equipped with a first hydraulic cylinder, and the telescopic end of the first hydraulic cylinder is equipped with a locking plate. The inner side of the locking plate is equipped with an anti-slip pad that is compatible with the support column.

[0007] The outer casing is equipped with controllers connected to the first hydraulic cylinder and the slider, respectively. The controllers control the rotation angle of the support column and the target mounting plate by controlling the rotation angle of the servo motor. The controllers also control the first hydraulic cylinder to extend the locking plate to lock the locking plate to the support column. The controllers control the rotation angle of the support column and the target mounting plate by controlling the rotation of the servo motor. At the same time, the controllers also control the first hydraulic cylinder to extend the locking plate, so that the anti-slip pad on the inner side of the locking plate can squeeze the support column. The first hydraulic cylinder applies pressure to increase the friction between the anti-slip pad and the support column, preventing the support column from rotating. This completes the rapid locking of the rotation angle of the support column and the target mounting plate, thereby ensuring the stability of the target on the target mounting plate.

[0008] A further technical solution is to install a pressure sensor connected to the controller between the locking plate and the anti-slip pad. The pressure sensor can monitor the pressure between the anti-slip pad and the support column in real time, so as to avoid the locking effect from deteriorating due to reduced pressure. When the controller detects that the pressure has decreased through the pressure sensor, the controller controls the first hydraulic cylinder to pressurize to ensure the stability of the pressure between the anti-slip pad and the support column.

[0009] A further technical solution is to install a second hydraulic cylinder inside the base, which is connected to the controller. The lifting end of the second hydraulic cylinder is connected to the bottom of the mounting plate. By setting the second hydraulic cylinder, the mounting plate, support column and target mounting plate can be lifted and lowered, thereby adjusting the height of the target in the target mounting plate and improving the applicability of the equipment.

[0010] A further technical solution is to have a limiting groove on the inner wall of the outer casing, and to install sliders on both sides of the mounting plate that are slidably connected to the limiting groove. By setting the limiting groove and sliders, the stability of the mounting plate when it is raised and lowered within the outer casing is ensured.

[0011] A further technical solution is to install a bearing housing on the mounting plate, with the bottom of the support column connected to the bearing housing, thus ensuring the smooth rotation of the support column on the mounting plate.

[0012] A further technical solution is that the target mounting plate is provided with a target mounting groove, and threaded holes are opened on both sides of the target mounting plate. Threaded rods are threaded into both sets of threaded holes. The ends of the two sets of threaded rods that are close to each other extend into the target mounting groove and are fitted with clamps. The clamps are responsible for clamping and fixing the target. By setting the threaded rods and clamps in cooperation, targets of different sizes can be fixed, further improving the applicability of the equipment.

[0013] This invention has the following advantages: It controls the rotation angle of the support column and target mounting plate by setting a controller to control the rotation of the servo motor. Simultaneously, the controller extends the locking plate of the first hydraulic cylinder, allowing the anti-slip pad inside the locking plate to press against the support column. The first hydraulic cylinder applies pressure, increasing the friction between the anti-slip pad and the support column, preventing the support column from rotating. This quickly locks the rotation angle of the support column and target mounting plate, ensuring the stability of the target on the target mounting plate. A pressure sensor monitors the pressure between the anti-slip pad and the support column in real time, preventing a decrease in pressure that could worsen the locking effect. When the controller detects a decrease in pressure through the pressure sensor, it controls the first hydraulic cylinder to increase pressure, ensuring the stability of the pressure between the anti-slip pad and the support column.

[0023] like Figures 1-2 As shown, a 3D camera target orientation adjustment component with self-locking function includes a base 1, a housing 2 mounted on the base 1, a mounting plate 3 mounted inside the housing 2, a rotatable support column 4 mounted on the mounting plate 3, a section of the support column 4 away from the mounting plate 3 extending outside the housing 2 and mounted with a target mounting plate 5, a servo motor 6 mounted on the mounting plate 3, a first gear 7 mounted on the power output end of the servo motor 6, and a second gear 8 meshing with the first gear 7 mounted on the support column 4.

[0024] A first hydraulic cylinder 10 is installed on the mounting plate 3. A locking plate 11 is installed on the telescopic end of the first hydraulic cylinder 10. An anti-slip pad 20 that is compatible with the support column 4 is installed on the inner side of the locking plate 11.

[0025] The outer casing 2 is equipped with a controller 9, which is connected to the first hydraulic cylinder 10 and the slider 15 respectively. The controller 9 controls the rotation angle of the support column 4 and the target mounting plate 5 by controlling the rotation angle of the servo motor 6. The controller 9 locks the locking plate 11 to the support column 4 by controlling the extension of the locking plate 11 driven by the first hydraulic cylinder 10. The controller 9 controls the rotation angle of the support column 4 and the target mounting plate 5 by controlling the rotation of the servo motor 6. At the same time, the controller 9 extends the locking plate 11 driven by the first hydraulic cylinder 10, so that the anti-slip pad 20 on the inner side of the locking plate 11 can squeeze the support column 4. The first hydraulic cylinder 10 applies pressure to increase the friction between the anti-slip pad 20 and the support column 4, preventing the support column 4 from rotating.

[0026] A pressure sensor 19 connected to the controller 9 is installed between the locking plate 11 and the anti-slip pad 20. The pressure sensor 19 can monitor the pressure between the anti-slip pad 20 and the support column 4 in real time to avoid the locking effect from deteriorating due to reduced pressure. When the controller 9 detects that the pressure has decreased through the pressure sensor 19, the controller 9 controls the first hydraulic cylinder 10 to pressurize to ensure the stability of the pressure between the anti-slip pad 20 and the support column 4.

[0027] A second hydraulic cylinder 13 connected to the controller 9 is installed inside the base 1. The lifting end of the second hydraulic cylinder 13 is connected to the bottom of the mounting plate 3. By setting the second hydraulic cylinder 13, the mounting plate 3, the support column 4 and the target mounting plate 5 can be lifted and lowered, thereby adjusting the height of the target in the target mounting plate 5 and improving the applicability of the equipment.

[0028] The inner sidewall of the outer shell 2 is provided with a limiting groove 14, and the two sides of the mounting plate 3 are equipped with sliders 15 that are slidably connected to the limiting groove 14. The stability of the mounting plate 3 when it is raised and lowered inside the outer shell 2 is ensured by setting the limiting groove 14 and the sliders 15.

[0029] A bearing seat 12 is installed on the mounting plate 3, and the bottom of the support column 4 is connected to the bearing seat 12. The bearing seat 12 is set to ensure the smooth rotation of the support column 4 on the mounting plate 3.

[0030] The target mounting plate 5 is provided with a target mounting groove 16. Threaded holes are opened on both sides of the target mounting plate 5. Threaded rods 17 are threadedly installed in both sets of threaded holes. The ends of the two sets of threaded rods 17 that are close to each other extend into the target mounting groove 16 and are fitted with clamping plates 18. The clamping plates 18 are responsible for clamping and fixing the target. By setting the threaded rods 17 and the clamping plates 18 in cooperation, targets of different sizes can be fixed, further improving the applicability of the equipment.
