[0033] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0034] See also Figure 1 The embodiment of the present application provides a hole position measurement system 100, including a detection subsystem 110 and a control subsystem 120. The detection subsystem 110 is mainly used to obtain image information of the object to be measured S, and the control subsystem 120 is mainly used to analyze the obtained graphic information.

[0035] The detection subsystem 110 includes a stage 111, a first light source 112, a second light source 113, a first camera 114, and a second camera 115. The stage 111 is used to carry the object to be tested. When the hole position measurement of the object to be tested is required, the object to be tested is placed on the stage 111; the first light source 112 is used to provide an upper light source to the object to be tested carried on the stage 111, that is, to illuminate the light source from above the object to be tested; the second light source 113 is used to provide a side light source to the object to be tested carried on the stage 111, that is, to illuminate the light source from the side of the object to be tested; the first camera 114 is used to obtain a top image of the object to be tested carried on the stage 111, that is, to take an image of the object to be tested from above the object to be tested; the second camera 115 is used to obtain a side image of the object to be tested carried on the stage 111, that is, to take an image of the object to be tested from the side of the object to be tested.

[0036] The control subsystem 120 includes an image acquisition module 121, a hole position calculation module 122, and a camera control module 123. The image acquisition module 121 is communicably connected to the first camera 114 and the second camera 115, and is used to acquire image information of the object to be measured acquired by the first camera 114 and the second camera 115; the hole position calculation module 122 is communicably connected to the image acquisition module 121, and is used to calculate the position of the hole on the object to be measured according to the image information acquired by the image acquisition module 121, and transmit the calculation result to the camera control module 123; the camera control module 123 is communicably connected to the first camera 114 and the second camera 115, and is used to control the first camera 114 and the second camera 115 to independently acquire the image of the object to be measured, or control the first camera 114 and the second camera 115 to independently acquire the image of the object to be measured according to the calculation result transmitted by the hole position calculation module 122.

[0037] Specifically, the first light source 112 may be equipped with high-brightness LED lamp beads to ensure that the light is evenly distributed and directly irradiates the surface of the object to be tested, providing a clear field of view for the first camera 114 to accurately capture the hole position of the object to be tested.

[0038] In the embodiment of the present application, when measuring the object to be measured, the second camera 115 is located on the side of the object to be measured, which can highlight the outline and side details of the object to be measured, so that the second camera 115 can measure the side position of the hole more accurately.

[0039] In some embodiments, the first camera 114 and the second camera 115 may be industrial cameras, which respectively acquire images of the object to be measured from the top and the side, and their high resolution and wide viewing angle range ensure all-round measurement accuracy.

[0040] The camera control module 123 in the embodiment of the present application is responsible for coordinating and controlling the operation of the first camera 114 and the second camera 115, and has the following features: 1) Synchronous control: ensuring that the two cameras can work synchronously and shoot at the same time to facilitate accurate data fusion and analysis. 2) Parameter adjustment: allowing the user or the system to automatically adjust the camera parameters, such as exposure time, focal length, etc., according to changes in the measurement environment to obtain the best image quality. 3) Real-time feedback: during the process of the camera capturing an image, it can provide real-time feedback information to the user, such as image quality indicators, to help the user determine whether the image needs to be recaptured.

[0041] In the embodiment of the present application, in combination with the first light source 112 and the second light source 113, and the first camera 114 and the second camera 115, the hole position measurement system 100 can capture images of the object to be measured from different angles, realize true multi-directional measurement, and greatly improve the detection accuracy of the hole position.

[0042] In some embodiments, the hole position calculation module 122 is equipped with an efficient processor and sufficient storage space, and this calculation module performs in-depth analysis on the captured image. For example, the advanced YOLO target detection technology can be used to quickly locate the hole and its edge of the object to be measured. At the same time, the module ensures that the object to be measured is complete and without any obstruction within the field of view of the first camera 114 and the second camera 115. If the image does not meet the measurement standard, it will work with the stage posture control module 124 described later to adjust the position of the stage and reacquire the image until the measurement requirements are met.

[0043] In some embodiments, the stage can drive the object to be tested to rotate and move horizontally. The control subsystem 120 also includes a stage posture control module 124, which is communicatively connected to the stage and is used to control the stage to drive the object to be tested to rotate and / or move horizontally.

[0044] In the embodiment of the present application, the operator can control the rotation and / or horizontal movement of the stage through the stage attitude control module 124. By controlling the movement of the stage, forward and backward movement and 360-degree horizontal rotation can be achieved, providing the possibility of measurement at multiple angles and directions.

[0045] In some embodiments, the stage posture control module 124 is a high-precision control module. When certain angles of the object to be measured are beyond the camera's field of view or need to be measured from different sides, the stage posture control module 124 can ensure that the object to be measured is always in the optimal measurement position.

[0046] In some embodiments, the stage includes a support platform, a rotation drive assembly, and a horizontal drive assembly. The support platform is used to support the object to be tested. When the object to be tested needs to be tested, it is directly placed on the support platform. The support platform is rotatably arranged on the rotation drive assembly, and the rotation drive assembly can drive the support platform to rotate. The rotation drive assembly can be relatively movably arranged on the horizontal drive assembly, and the horizontal drive assembly can drive the rotation drive assembly to move horizontally.

[0047] In some embodiments, the hole position calculation module 122 can be communicatively connected to the stage posture control module 124, the hole position calculation module 122 can transmit the calculation results to the stage posture control module 124, and the stage posture control module 124 can adjust the control stage to drive the object to be tested to rotate and / or move horizontally according to the calculation results.

[0048] In an embodiment of the present application, when the hole position calculation module 122 determines that the captured image does not meet the measurement requirements, the stage posture control module 124 can automatically adjust the position of the object to be measured according to the calculation results to obtain the optimal measurement angle, saving manual adjustment time and improving work efficiency.

[0049] In some embodiments, the control subsystem 120 further includes a storage module 125, which is communicatively connected to the hole position calculation module 122 and is used to store image information and calculation results. In the embodiment of the present application, the storage module 125 uses a reliable data backup and recovery mechanism to prevent data loss and ensure the security of the measurement data.

[0050] See also Figure 2 and Figure 3 In some embodiments, the hole position measurement system 100 also includes a peripheral subsystem 130, which includes a human-machine interface 131 and a printer 132; the human-machine interface 131 is communicatively connected to the control subsystem 120 to provide an interface for the operator to interact with the control subsystem 120; the printer 132 is communicatively connected to the human-machine interface 131 to print out the required detection data according to the interaction results of the human-machine interface 131.

[0051] In the embodiment of the present application, the human-machine interface 131 is a user-friendly interactive interface that allows the operator to easily configure measurement parameters, view measurement data, and perform necessary system debugging, making the measurement process simple and efficient; the printer 132 prints out the required detection data according to the interaction results of the human-machine interface 131.

[0052] In some embodiments, the human-machine interface 131 includes a camera control area 1311 and a calculation result display area 1312. The camera control area 1311 is used to provide the operator with a camera parameter adjustment interface, and the calculation result display area 1312 is used to display the calculation results to the operator. In the embodiment of the present application, the intuitive design of the human-machine interface 131 makes the measurement process simpler and more efficient.

[0053] In some embodiments, the human-machine interface 131 further includes a stage control area 1313, which is used to provide the operator with a stage control parameter adjustment interface. In the embodiment of the present application, the intuitive design of the human-machine interface 131 makes the measurement process simpler and more efficient.

[0054] The working process of the hole position measurement system 100 is as follows: After the hole position measurement system 100 is started and self-checked, the user places the object to be measured on the stage and ensures that it is stable. Subsequently, the first light source 112 and the second light source 113 are started to fully illuminate the object to be measured, and at the same time, the first camera 114 and the second camera 115 capture the image of the object to be measured and transmit it to the image acquisition module 121. These image data are then passed to the hole position calculation module 122, where the image is analyzed using the YOLO target detection algorithm to locate the hole and edge of the object to be measured. If the hole position measurement system 100 determines that the current image does not meet the measurement requirements, the position of the stage will be automatically adjusted, and then the image will be recaptured and analyzed until the standard is met. Once the position of the hole is successfully located, the measurement result will be displayed on the human-machine interface 131 for the user to view and save. The user can debug and set the system through the interface at any time as needed. After completing the measurement, the user can choose to shut down the system or continue with the next round of measurement.

[0055] Based on the aforementioned hole position measurement system 100, it has the following beneficial effects:

[0056] 1. All-round measurement: Combining the first light source 112 and the second light source 113, and the two first cameras 114 and the second camera 115, the hole position measurement system 100 can capture images of the object to be measured from different angles, realize true multi-directional measurement, and greatly improve the detection accuracy of the hole position.

[0057] 2. Adaptive adjustment: When the hole position measurement system 100 determines that the captured image does not meet the measurement requirements, the stage posture control module 124 can automatically adjust the position of the object to be measured to obtain the best measurement angle, saving manual adjustment time and improving work efficiency.

[0058] 3. Reduce human errors: Through a fully automated detection process, errors caused by human factors are greatly reduced, thus ensuring the reliability and repeatability of the measurement results.

[0059] 4. Friendly user interaction: The human-machine interface 131 is intuitive and easy to operate, allowing users to easily set parameters and view results, greatly enhancing the user experience.
