Description

Technical Field

[0001] The present invention relates to the technical field of camera height adjustment, and particularly relates to a camera height adjustment device for egg detection. Background Technique

[0002] A camera, also known as a computer camera, is a video input device that is widely used in video conferencing, telemedicine, real-time monitoring, etc. Ordinary people can also communicate with each other through the camera over the network with images and sounds. In addition, people can also use it for various current popular digital images and audio-visual processing. A camera generally has basic functions such as video shooting / transmission and static image capture. After collecting an image through a lens, the photosensitive component circuit and control component in the camera process the image and convert it into a digital signal that can be recognized by a computer, and then it is input into the computer through a parallel port or USB connection and restored by software for image use. Cameras are applied in product quality inspection, which is mainly reflected in capturing images of products through cameras, and then using image processing technology and machine vision systems to conduct automated and non-contact quality evaluation of products.

[0003] In the process of monitoring the quality of egg liquid, it is necessary to evaluate the appearance characteristics of the egg liquid. Researchers mostly use the method of visual observation to specifically monitor aspects such as the coverage area, color, transparency, and impurities of the egg liquid. The intervention of the above-mentioned image recognition technology in the field of egg liquid detection can obviously improve the detection efficiency of the egg liquid. However, there are still unsolved problems in the application of this technology. In the process of the camera capturing images of the egg liquid, the height of the camera has a direct impact on the integrity of the captured egg liquid images. Generally speaking, the higher the camera is installed, the wider its field of view, and thus the corresponding coverage area will increase. However, this does not mean that the camera can infinitely increase the installation height to expand the coverage area. Because too high an installation height may lead to problems such as image distortion, affecting the image quality and the accuracy of area measurement. In addition, the coverage areas of the egg liquids of different eggs are also different. Therefore, the images captured by a camera with a fixed position cannot meet the requirements of the egg liquid detection for image accuracy. To reduce the impact of the difference in the egg liquid coverage area on the batch detection work of the egg liquid, a device that can preset and finely adjust the camera height according to the actual state of the egg liquid is needed. Summary of the Invention

[0043] (2) By setting the support mechanism and the conveying mechanism, the present invention can realize batch detection of the egg liquid.

[0045] (4) In the present invention, by setting the counterweight, the maximum static friction force between the tray and the support plate is increased, preventing relative rotation between the tray and the support plate. In addition, since the tray is transported above the support plate along with the conveyor belt body, due to inertia and other reasons, the preset shooting position of the tray and the camera may shift. However, the counterweight is in the shape of a frustum of a cone, and under the action of gravity, it can just be embedded into the groove, thus realizing the position correction of the tray.

[0054] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0055] Please refer to Figures 1 - 2 As shown in the figure, a camera height adjustment device for egg product detection includes:

[0056] A detection table 1, the upper end surface of the detection table 1 is horizontal, and a support rod 11 is fixedly installed on the upper end, and a top plate 12 is fixedly installed at the upper end of the support rod 11;

[0057] An adjustment mechanism 2, including a lifting assembly 21 and a driving assembly 22, the lower end of the lifting assembly 21 is detachably installed with a camera 5, and the driving assembly 22 is installed on the top plate 12 for driving the telescopic movement of the lifting assembly 21;

[0058] A support mechanism 3, including a support assembly 31 and a lifting assembly 32, the support assembly 31 is used for supporting the egg liquid to be detected, and the lifting assembly 21 is arranged on the upper end of the detection table 1 for lifting the support assembly 31;

[0059] A conveying mechanism 4, including a conveyor belt body 41 for conveying egg liquid.

[0060] Through the above technical solutions, this embodiment provides the main structural content of a camera height adjustment device for egg product detection. The monitoring table provides a horizontal overall support surface for egg liquid detection. Through the setting of the adjustment mechanism 2, the height of the camera 5 can be adjusted according to specific working requirements. While ensuring that the camera 5 can capture a complete image of the egg liquid coverage area, the height of the camera 5 can also be adjusted according to the actual state of the egg liquid to ensure the image quality, so as to improve the accuracy of the subsequent measurement of the egg liquid coverage area. In addition, through the setting of the support mechanism 3 and the conveying mechanism 4, batch detection of egg liquid can be realized. During the specific detection process, the lifting assembly 32 drives the support assembly 31 to lift the egg liquid from the conveyor belt body 41, and then put the egg liquid back on the conveyor belt body 41 after the detection. While providing a support carrier for egg liquid detection, it can also automatically complete loading and unloading, thus improving the detection efficiency.

[0061] Please refer to Figure 3 As shown in the figure, the lifting assembly 21 includes:

[0062] A first sleeve 211, the first sleeve 211 penetrates through the top plate 12 and is fixedly connected to the top plate 12;

[0063] A second sleeve 212, axially slidably connected within the first sleeve 211, with a mounting plate fixedly provided at the lower end of the second sleeve 212, and the camera 5 detachably mounted at the lower end of the mounting plate;

[0064] A main shaft 213, fixedly sleeved with a first threaded sleeve 2131 and a second threaded sleeve 2132 on the main shaft 213, the pitch of the first threaded sleeve 2131 being greater than the pitch of the second threaded sleeve 2132, and the first threaded sleeve 2131 being threadedly connected to the first sleeve 211, and the second threaded sleeve 2132 being threadedly connected to the second sleeve 212.

[0065] Through the above technical solution, the present embodiment provides the specific structure of the lifting assembly 21. The camera 5 is detachably mounted at the lower end of the mounting plate, facilitating replacement and maintenance. The cooperation of the first sleeve 211, the second sleeve 212, and the main shaft 213 can achieve height adjustment of the camera 5. Specifically, when the main shaft 213 rotates, it drives the second sleeve 212 to move up and down within the first sleeve 211, thereby adjusting the height of the camera 5. Since the change in the optimal object distance caused by the difference in the egg liquid coverage area is subtle, in order to achieve a fine adjustment effect on the height of the camera 5, it should also be noted that the thread helix directions of the first threaded sleeve 2131 and the second threaded sleeve 2132 are the same, and the pitch of the first threaded sleeve 2131 is slightly greater than the pitch of the second threaded sleeve 2132. When the main shaft 213 rotates one week, the adjustment amount of the height of the camera 5 is the pitch difference between the first threaded sleeve 2131 and the second threaded sleeve 2132, achieving fine adjustment of the height of the camera 5. It should also be noted that the second sleeve 212 is slidably connected to the first sleeve 211 in the vertical direction, and the second sleeve 212 does not rotate with the rotation of the main shaft 213.

[0066] Please refer to Figure 3 as shown, the driving assembly 22 includes:

[0067] A rotating bracket 221, fixedly provided at the upper end of the top plate 12, with a bearing provided within the rotating bracket 221;

[0068] A worm gear 222, coaxially and fixedly connected to a rotating tube at the lower end of the worm gear 222, the rotating tube being rotatably connected to the upper end of the rotating bracket 221 through the bearing, the main shaft 213 passing through the worm gear 222 and being movably connected to the worm gear 222 through a spline;

[0069] A servo motor 223, fixedly provided on the top plate 12, the output end of the servo motor 223 being drivingly connected to a worm 224, the worm 224 meshing with the worm gear 222.

[0070] Through the above technical solution, this embodiment provides the specific structure of the driving component 22. The top plate 12 provides fixed support for the driving component 22 and the lifting component 21. During the specific process of adjusting the height of the camera 5, the servo motor 223 directly drives the screw to rotate and drives the worm gear 222 meshed with it to rotate. Since the worm gear 222 and the main shaft 213 are movably connected by splines and there is no constraint on the vertical direction of the main shaft 213, the main shaft 213 rotates synchronously with the rotation of the worm gear 222 and moves up and down. In addition, the cooperative transmission between the worm 224 and the worm gear 222 has a self-locking effect, which can lock the current position of the camera 5 in time after the height adjustment of the camera 5 is completed.

[0071] Please refer to Figures 4 - 5 as shown in the figure, the support assembly 31 includes:

[0072] A tray 311, and a frustum-shaped counterweight 312 is fixedly arranged at the lower end of the tray 311;

[0073] A support plate 313, and a frustum-shaped groove 3131 adapted to the counterweight 312 is formed at the upper end of the support plate 313;

[0074] A low-speed motor 314, and the output end of the low-speed motor 314 is in transmission connection with the support plate 313.

[0075] Through the above technical solution, this embodiment provides the specific content of the support assembly 31. After the action of lifting the egg liquid is completed, the low-speed motor 314 drives the support plate 313 and the tray 311 to rotate intermittently, and the images of the egg liquid are collected during the pause of the intermittent rotation. In this way, multiple images of the egg liquid can be captured and corresponding detections can be carried out in combination with image recognition technology. The reason for capturing images and detecting multiple times is that the egg white part of the egg liquid is transparent, so a single image capture may not necessarily obtain a complete and clear outline of the egg liquid. By rotating the egg liquid and capturing and detecting images multiple times, multiple data of the coverage area of the egg liquid can be obtained. If the data differences are not significant, it indicates that the captured outline of the egg liquid is relatively complete and clear. It should also be noted that the setting of the counterweight 312 is to increase the maximum static friction force between the tray 311 and the support plate 313 to prevent relative rotation between the tray 311 and the support plate 313. In addition, since the tray 311 is transported to the upper part of the support plate 313 along with the conveyor belt body 41, the tray 311 may be offset from the preset shooting position of the camera 5 due to inertia and other reasons. The counterweight 312 is frustum-shaped and can just be embedded in the groove 3131 under the action of gravity, so as to realize the position correction of the tray 311. To sum up, the support assembly 31 plays a role in positioning and supporting the egg liquid.

[0076] The belt surface of the conveyor belt body 41 is provided with through holes 411, and the inner diameter of the through holes 411 is smaller than the diameter of the tray 311. Through the above technical solution, the lower end of the tray 311 can be embedded in the through holes 411 and conveyed by the conveyor belt body 41.

[0077] Please refer to Figures 4 - 5 As shown, the lifting assembly 32 includes:

[0078] A cross plate 321, the cross plate 321 is horizontally arranged between the upper and lower belt surfaces of the conveyor belt body 41, and the low-speed motor 314 is fixedly installed on the cross plate 321;

[0079] Electric push rods 322, there are two electric push rods 322, and they are respectively located at both ends of the cross plate 321. The electric push rods 322 are installed at the upper end of the detection table 1, and the output ends of the electric push rods 322 are fixedly connected to the cross plate 321.

[0080] Through the above technical solution, the present embodiment provides the specific structure of the lifting assembly 32. During the process of lifting the tray 311 and the egg liquid in the tray 311, the two electric push rods 322 synchronously push the cross plate 321 to move upward to complete the lifting action of the support assembly 31. It should also be noted that the cross plate 321 is located between the upper and lower belt surfaces of the conveyor belt body 41. Therefore, during the entire lifting action, neither the lifting assembly 32 nor the support assembly 31 will touch the conveyor belt body 41, ensuring the stability of the egg liquid transportation.

[0081] Please refer to Figure 6 As shown, a control system of a camera height adjustment device for egg product detection, the system includes:

[0082] An acquisition unit, including a pressure sensor arranged in the groove 3131;

[0083] An analysis module, including a data processing unit and a measurement and analysis unit.

The measurement and analysis unit is used to analyze the measurement data of the egg liquid coverage area and determine the adjustment strategy according to the analysis result;

[0084] A control module, used to adjust the height of the camera 5 according to the initial height value and the adjustment strategy.

[0085] Through the above technical solution, the content of the control system of the camera height adjustment device for egg product detection in this embodiment can obtain the pressure value data of the egg liquid to be measured through the setting of the acquisition unit. The processing unit processes the measured pressure value data and determines the initial height value of the camera 5 according to the processing result. At the initial height, the capture of the egg liquid image and the measurement of the egg liquid coverage area are completed. Then, the measurement and analysis unit analyzes the measurement data of the egg liquid coverage area and determines the adjustment strategy according to the analysis result. Finally, the control module adjusts the height of the camera 5 according to the initial height value and the adjustment strategy.

[0086] The process of processing the pressure value data includes:

[0087]

[0088] By the formula Calculate and obtain the initial height value of the camera 5 ;

[0089] Wherein, is the pressure value measured by the pressure sensor; is the acceleration due to gravity; is the mass of the tray 311; is the standard value of the density of the egg liquid; is a preset coefficient; is the focal length of the camera 5; is the aperture value of the camera 5; is a preset conversion function; is a preset offset value, and .

[0090] Through the above technical solution, this embodiment provides the specific process of processing the pressure value data. Specifically, by the formula ; Calculate and obtain the initial height value of the camera 5 ; The formula mainly predicts the coverage area of the egg liquid to obtain a predicted value , and then is imported into the trained mapping model, that is, by the formula Obtain the initial height value , it should be noted that is a preset coefficient, which can be specifically obtained according to historical experimental data; is a preset conversion function, which is specifically related to the performance characteristics of the camera 5. The mapping relationship is obtained by fitting experimental data and will not be elaborated here. In addition, the height of the camera 5 is specifically the distance from the camera 5 to the egg liquid, that is, the object distance.

[0091] The process of analyzing the measurement data of the egg liquid coverage area includes:

[0092] Driven by the low-speed motor 314, the tray 311 rotates intermittently. During each stop period of the intermittent rotation, an egg liquid image is captured, and n data of the egg liquid coverage area are measured through image recognition technology:

[0093] Through the formula Calculate the standard deviation of the n data of the measured egg liquid coverage area , where Is the value of the egg liquid coverage area measured for the i-th time;

[0094] Compare the standard deviation With the preset threshold For comparison:

[0095] If , then output As the final measured value of the egg liquid coverage area;

[0096] If , then the adjustment amount for the height of the camera 5 is After the vertical upward adjustment, measure the egg liquid coverage area again, where Is the preset proportionality coefficient.

[0097] Through the above technical solution, this embodiment provides a process for analyzing the measurement data of the egg liquid coverage area. First, driven by the low-speed motor 314, the tray 311 rotates intermittently. During each stop period of the intermittent rotation, an egg liquid image is captured, and n data of the egg liquid coverage area are measured through image recognition technology. Then, through the formula Calculate the standard deviation of the n data of the measured egg liquid coverage area , when , it indicates that the contour of the egg liquid image captured by the camera 5 at the initial height is relatively clear and complete. Therefore, output As the final measured value of the egg liquid coverage area, Is the average value of n , and when , it indicates that the egg liquid image captured by the camera 5 is not clear and complete.
