Description

Technical Field

[0001] This invention relates to an image recognition device and method, belonging to the field of image recognition technology. Background Technology

[0002] With the iterative upgrades of artificial intelligence and deep learning technologies, image recognition technology has been widely applied in many fields such as security monitoring and industrial inspection. This technology relies on computer vision and deep learning algorithms to achieve automatic recognition and intelligent analysis of image information. In industrial inspection scenarios, the industry commonly uses image recognition equipment equipped with industrial cameras to complete inspection work. This type of equipment mainly consists of a mounting bracket and an industrial camera. By fixing the mounting bracket to the conveyor frame of the production line, the industrial camera is suspended directly above the conveyor section, maintaining a constant shooting height.

[0003] During the operation, the product to be inspected moves continuously with the conveyor mechanism. When the product moves to the camera's shooting area, the industrial camera completes image acquisition. The image is then analyzed and judged by the supporting software to achieve image recognition of the product. Similar to the above steps, batch image recognition of products can be performed to provide data support for product quality judgment.

[0004] Existing image recognition devices have significant technical drawbacks: during dynamic product transport, the relative motion between the camera and the product easily causes blurred images; simultaneously, the fixed shooting height of industrial cameras, influenced by the product's shape and structure, easily creates shadows in local areas, further exacerbating image blur and significantly increasing image recognition errors. While using a stationary acquisition method to optimize imaging can eliminate motion blur, it greatly increases process time and reduces production inspection efficiency, failing to balance inspection accuracy and production efficiency, and severely impacting overall image quality and recognition accuracy.

[0010] Furthermore, the data acquisition device includes a lifting device, which is installed at the lower end of the second nut seat. A movable plate is provided at the lower end of the movable part of the lifting device. A telescopic rod is installed between the movable plate and the second nut seat, and the telescopic rod is located at the front of the lifting device. A terminal and a power supply are arranged sequentially from front to back on the upper end of the movable plate, and the terminal and the power supply are located between the telescopic rod and the lifting device. An industrial camera is mounted on the lower end of the mobile board. A first sensor is set at the front end of the industrial camera.

[0012] An image recognition method includes the following steps: Step 1: Equipment verification. Check whether the power supply is outputting power normally, and check whether the industrial camera, first sensor, second sensor, detector, first drive device, second drive device, third drive device, and lifting device are working properly. The second step is target detection. The detector detects whether there is a target product, the relevant distance, and the trajectory. If there is interference between the target product and the product in front, the two first driving devices and two rotating wheels will make the two baffles rotate inward and make the two baffles parallel, thereby causing the target product to stop for a corresponding time. After the target product moves to the detection position, the second sensor will collect the height data of the target product, while the first sensor will collect the motion data of the target product. The third step is preliminary identification. The industrial camera will capture an overall image of the target product and record it as a preliminary target image. The preliminary target image will be analyzed and it will be determined which position on the preliminary target image is blurred. At the same time, based on the motion data, the moving plate and the industrial camera will move synchronously with the target product through the third drive device, the second transmission box, the second lead screw and the second nut seat. The fourth step is accurate identification. Based on the analysis and judgment results of the preliminary target image, the second drive device, the first transmission box, the first lead screw and the first nut seat are used to move the movable box, the moving plate and the industrial camera to the corresponding positions on the left and right. Through the relevant height data, the lifting device is used to move the moving plate and the industrial camera to the appropriate position. The industrial camera will collect local images of the relevant local areas of the target product and record them as accurate images. Step 5: Repeat step 4 to acquire accurate images of all blurred areas of the target product on the initial target image; Step 6: Analysis and Modeling. Based on the preliminary target image and the precise image, construct the target image model of the target product, and analyze and recognize the target image model to complete the image recognition of the target product.

[0013] The beneficial effects of this invention are: Data related to the target product is collected using the first and second sensors. Simultaneously, an industrial camera captures an overall image of the target product, identifying any and the number of blurred areas. A third servo motor, a second transmission box, a second lead screw, and a second nut seat enable the moving plate and industrial camera to move synchronously with the target product. The first servo motor, first transmission box, first lead screw, and first nut seat move the moving plate and industrial camera to appropriate positions laterally. An electric push rod and the moving plate lower the industrial camera to a suitable position. The industrial camera then captures localized images of blurred areas within the target product. This process is repeated for all blurred images of the target product. Based on all captured images, a precise image model of the target product is constructed. This image model is then analyzed and recognized, completing the image recognition of the target product. This method enables location-based directional image acquisition of the target product, effectively reducing image blurring, lowering the probability of errors in image recognition, and significantly improving the accuracy and overall imaging quality.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

The first nut seat 14 is mounted on the annular end of the first lead screw 15 via a ball nut pair, and the first nut seat 14 extending out of the lower side of the top box 1 is slidably connected inside the top box 1. The first nut seat 14 provides an installation carrier for the movable box 5. The first transmission box 12 is mounted on the right end of the top box 1, and the output shaft of the first transmission box 12 is connected to the first lead screw 15. The second drive device is located on the upper right side of the top box 1, and the output shaft of the second drive device is connected to the input shaft of the first transmission box 12. The second drive device and the first transmission box 12 work together to rotate the first lead screw 15. The second drive device can be a first servo motor 11. The movable box 5 is installed on the lower end of the first nut seat 14. The movable box 5 provides a mounting carrier for components such as the second lead screw 55. The second lead screw 55 is rotatably connected inside the movable box 5. The second nut seat 56 moves back and forth through the second lead screw 55. The second nut seat 56 is set on the annular end of the second lead screw 55 through a ball nut pair. The second nut seat 56 extends out of the lower side of the movable box 5 and is slidably connected inside the movable box 5. The second nut seat 56 provides a mounting carrier for components such as lifting equipment. The second transmission box 54 is installed on the rear end of the movable box 5, and the output shaft of the second transmission box 54 is connected to the second lead screw 55. The third drive device located on the rear side of the top box 1 is set on the upper rear side of the movable box 5. The output shaft of the third drive device is connected to the input shaft of the second transmission box 54. The third drive device works with the second transmission box 54 to rotate the second lead screw 55. The third drive device can be a third servo motor 53. A lifting device is installed on the lower end of the second nut seat 56. The lifting device drives the moving plate 4 to move up and down. The lifting device can be an electric push rod 41. The moving plate 4 is set on the lower end of the movable part of the lifting device. The moving plate 4 provides a mounting carrier for components such as the power supply 43. The telescopic rod 42 located on the front side of the lifting device is installed between the moving plate 4 and the second nut seat 56. The telescopic rod 42 guides the movement of the moving plate 4. A terminal 46 and a power supply 43 are arranged sequentially from front to back on the upper end of the mobile plate 4. The terminal 46 and the power supply 43 are located between the telescopic rod 42 and the lifting device. The power supply 43 is electrically connected to the lifting device, the terminal 46, the industrial camera 44, the first sensor 45, and the second sensor 47. The terminal 46 is also electrically connected to the lifting device, the industrial camera 44, the first sensor 45, and the second sensor 47. The terminal 46 is wirelessly connected to the controller. The power supply 43 provides power to the terminal 46 and other components, and the terminal 46 transmits the relevant collected data to the controller. An industrial camera 44 is mounted on the lower end of a movable plate 4 and is used for image acquisition. A first sensor 45 is mounted on the front end of the industrial camera 44 and is used to acquire the speed of the target product. The first sensor 45 can be a laser sensor. A second sensor 47 located in front of the first sensor 45 is mounted on the lower end of the movable plate 4 and is used to acquire the height of the target product. The second sensor 47 can be an ultrasonic height sensor. Mounting base 52 is located on the front end of the movable box 5, and the cross-section of mounting base 52 is a trapezoid with a narrow bottom and a wide top. Mounting base 52 provides a mounting carrier for detector 51. Detector 51 is mounted on the inclined front end of mounting base 52. Detector 51 is used to collect data on whether there is a target product, the relevant distance, and the trajectory. Detector 51 can be a radar. The functional frame 21 located directly in front of the top box 1 has an inverted U-shaped structure, and the lower ends of the two vertical parts of the functional frame 21 are respectively connected to the upper ends of the two base plates 2. The slider 22 is installed on the upper end of the movable box 5, and the slider 22 is slidably connected to the lower end of the horizontal part of the functional frame 21. The upper end of the slider 22 extends into the horizontal part of the functional frame 21. The slider 22 and the functional frame 21 work together to guide the movement of the movable box 5 on the one hand, and increase the installation stability of the movable box 5 on the other hand.

[0018] First, two base plates 2 are symmetrically installed on the upper end of the frame of the conveyor section in the production line. During the operation of the production line, the detector 51 first checks whether there is a target product on the conveyor section in the production line. If a target product is detected, the detector 51 simultaneously collects the relevant distance and trajectory of the target product, and analyzes and calculates the collected information. If it is determined that the target product has moved to the detection position, the second sensor 47 will collect the height data of the target product, while the first sensor 45 will collect the motion data of the target product. At the same time, the industrial camera 44 will collect the overall image of the target product at the detection position, and analyze and judge the collected overall image to determine whether there are blurred areas and how many there are. Then, the collected information is transmitted to the controller through the terminal 46, and the controller sends a corresponding signal according to the collected information. The third servo motor 53 receives the relevant signal and performs the relevant work. Then, with the assistance of the second transmission box 54, the second lead screw 55 is rotated. Since the second lead screw 55 is connected to the second nut seat 56 through a ball nut pair, the rotation of the second lead screw 55 will cause the second nut seat 56 to move backward along the movable box 5, and cause the moving plate 4, industrial camera 44 and other components to move synchronously with the target product. At the same time, the first servo motor 11 receives relevant signals and performs relevant operations, thereby rotating the first lead screw 15 with the assistance of the first transmission box 12. Since the first lead screw 15 is connected to the first nut seat 14 through a ball nut pair, the rotation of the first lead screw 15 will cause the first nut seat 14 to move left and right along the top box 1, thereby moving the moving plate 4, industrial camera 44 and other components to the appropriate positions, so that the industrial camera 44 is located directly above a certain blurry local area in the target product. At the same time, the electric push rod 41 receives relevant signals and performs relevant operations, thereby driving the moving plate 4 to move down, which in turn moves the industrial camera 44 to a suitable position. Then, the industrial camera 44 is used to perform local image acquisition on the blurred images in the target product. The same steps are used to perform local image acquisition on all blurred images in the target product. Then, based on all the acquired images, a precise image model of the target product can be constructed, and the target image model can be analyzed and identified to complete the image recognition of the target product. This enables location-based orientation image acquisition of the target product, effectively reducing image blurring and the probability of errors in image recognition, and significantly improving the accuracy of image recognition and overall imaging quality.

[0019] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, two circular functional boxes 3 are respectively installed on the front end of two base plates 2. The functional boxes 3 and the first drive device and other components provide the mounting carrier. The rear end faces of the two functional boxes 3 are recessed inward to form openings 37, and the openings 37 extend to the inner wall of the functional boxes 3. The openings 37 provide a rotation channel for the baffle 32. Two rotating wheels 36 are rotatably connected to the two functional boxes 3 respectively, and the rotating wheels 36 provide the mounting carrier for the baffle 32. The fixed parts of the two first drive devices are respectively installed on the upper middle part of the two function boxes 3, and the output shafts of the two first drive devices are respectively connected to the two rotating wheels 36. The rotating wheels 36 are driven to rotate through the first drive devices. The first drive devices can be second servo motors 31. Two baffles 32 are respectively installed on the outer ends of the two rotating wheels 36, and the two baffles 32 pass through the two openings 37 respectively. The two baffles 32 are used together to pause the target product. Both baffles 32 have outward recessed threaded holes on their inner end faces. These threaded holes provide installation space for the screws 35. The two screws 35 are threaded into the two threaded holes respectively, and the screws 35 extend out of the threaded holes. The screws 35 and the threaded holes are used to adjust the left and right positions of the auxiliary plate 33. Two auxiliary plates 33 are rotatably connected to the inner ends of two screws 35, providing a mounting carrier for the screws 35. Multiple round holes are formed by outward recesses on the inner end faces of the two baffles 32. Multiple round rods 34 are installed on the inner ends of the two auxiliary plates 33, and the outer ends of the multiple round rods 34 are respectively set on the inner ends of the multiple round holes, with the round rods 34 extending into the round holes. The multiple round rods 34 and the multiple round holes work together to guide the movement of the auxiliary plates 33 on the one hand, and increase the installation stability of the auxiliary plates 33 on the other hand.

[0020] Before use, the screw 35 can be rotated according to the width of the target product. Since the screw 35 is threadedly connected to the threaded hole, the rotation of the screw 35 causes movement, which in turn moves the corresponding auxiliary plate 33 to the corresponding position, thereby adjusting the distance between the two auxiliary plates 33. This allows for pause operations on target products of different specifications, thus satisfying the image recognition operation for target products of different specifications. Furthermore, the initial state of components such as the baffle 32 is parallel to the corresponding base plate 2.

[0021] During the image recognition process of the target product, the third sensor will collect relevant information of the product to be identified behind it. If there is interference between the product to be identified and the target product, two second servo motors 31 can be activated to drive the rotating wheel 36 to rotate, thereby causing the corresponding baffle 32 to rotate 90° inward along the opening 37, and causing the screw 35 and auxiliary plate 33 and other components to rotate 90°. At this time, the two baffles 32 and other components will stop the product to be identified. After the product to be identified pauses for a certain period of time, the second servo motor 31 and the rotating wheel 36 are used to rotate the baffle 32 and other parts back to their original positions, thereby releasing the pause process of the product to be identified and allowing the product to resume normal movement. Then, the subsequent components will perform normal image recognition operations on the product to be identified, realizing orderly pause operations on the product, effectively reducing the probability of interference in image recognition between two adjacent products, effectively reducing the probability of image recognition errors, effectively ensuring the quality of image recognition and performing normal batch operations.

[0022] Example 3: Figures 9-11 As shown, the movable frame 6 located in front of the third servo motor 53 is slidably connected to the outer end of the top box 1, and the movable frame 6 is arranged in an inverted U-shape. The lower ends of the two vertical parts of the movable frame 6 are fixedly connected to the upper end of the movable box 5. The movable frame 6 provides a mounting carrier for components such as the second clamp 64. The fixing plate 62 located on the left side of the movable frame 6 is installed on the upper end of the top box 1. The fixing plate 62 provides a mounting carrier for components such as the first clamp 621. The second clamp 64 is installed on the upper end of the movable frame 6, and the first clamp 621 is set on the upper end of the fixed plate 62. The first clamp 621 and the second clamp 64 are used together to fix and clamp the connecting wire. The folding frame 61 located at the upper end of the top box 1 is movably installed between the movable frame 6 and the fixed plate 62. The folding frame 61 provides a mounting carrier for the fixed rod 63. Fixed rods 63 are installed on the upper ends of all movable parts on the front and rear sides of the folding frame 61. The fixed rods 63 provide a mounting carrier for the flat plate 631. Flat plates 631 are set on the upper ends of all fixed rods 63. The flat plates 631 provide a mounting carrier for the guide wheels 632. Two guide wheels 632 are symmetrically rotated and connected on the upper end of the flat plate 631.

[0023] When assembling the third servo motor 53, firstly, a connecting wire is assembled on the third servo motor 53. Then, the connecting wire is inserted into the first clamp 621, and the first clamp 621 is used to secure the connecting wire, so that the connecting wire between the first clamp 621 and the third servo motor 53 is always taut. Then, the connecting wire is assembled from right to left into multiple assemblies formed by the flat plate 631 and two guide wheels 632, with the connecting wire positioned between the corresponding two guide wheels 632. Then, the connecting wire is inserted into the second clamp 64, and the second clamp 64 is used to secure the connecting wire, so that the connecting wire between the first clamp 621 and the second clamp 64 is in a serpentine state. During the left-right movement of the movable box 5, the movable frame 6 will also move left-right, thereby retracting or extending the folding frame 61. This causes the fixed rods 63 located on the front and rear sides to move inward or outward, thus causing the two rows of sorting structures to move synchronously inward and outward. This allows the connecting wires located between the first clamp 621 and the second clamp 64 to be retracted or extended, effectively sorting the connecting wires. This reduces the probability of damage to the connecting wires of the third servo motor 53 caused by the movement of the movable box 5, and also reduces the probability of jamming in the movable box 5. This further reduces the probability of errors in image recognition, effectively ensuring the quality and effect of image recognition.

[0024] An image recognition method includes the following steps: Step 1: Equipment verification. Check whether the power supply 43 is outputting power normally, and check whether the industrial camera 44, the first sensor 45, the second sensor 47, the detector 51, the second servo motor 31, the first servo motor 11, the third servo motor 53, and the electric push rod 41 are working properly. The second step is target detection. Detector 51 detects whether there is a target product, the relevant distance, and the trajectory. If there is interference between the target product and the product in front, two second servo motors 31 and two rotating wheels 36 are used to rotate two baffles 32 inward so that the two baffles 32 are parallel, thereby causing the target product to stop for a corresponding time. After the target product moves to the detection position, the second sensor 47 collects the height data of the target product, while the first sensor 45 collects the motion data of the target product. The third step is preliminary identification. The industrial camera 44 will capture the overall image of the target product and record it as a preliminary target image. It will analyze the preliminary target image and determine which position on the preliminary target image has a blurred local area. At the same time, based on the motion data, the moving plate 4 and the industrial camera 44 will move synchronously with the target product through the third servo motor 53, the second transmission box 54, the second lead screw 55 and the second nut seat 56. The fourth step is accurate identification. Based on the analysis and judgment results of the preliminary target image, the first servo motor 11, the first transmission box 12, the first lead screw 15 and the first nut seat 14 are used to move the movable box 5, the moving plate 4 and the industrial camera 44 to the corresponding positions. Through the relevant height data, the electric push rod 41 is used to move the moving plate 4 and the industrial camera 44 to the appropriate position. The industrial camera 44 will collect local images of the relevant local areas of the target product and record them as accurate images. Step 5: Repeat step 4 to acquire accurate images of all blurred areas of the target product on the initial target image; Step 6: Analysis and Modeling. Based on the preliminary target image and the precise image, construct the target image model of the target product, and analyze and recognize the target image model to complete the image recognition of the target product.

7. An image recognition method, using the image recognition device according to claim 6, characterized in that, Includes the following steps: Step 1: Equipment verification. Check whether the power supply (43) outputs power normally, and check whether the industrial camera (44), the first sensor (45), the second sensor (47), the detector (51), the first drive device, the second drive device, the third drive device, and the lifting device can work normally. The second step is target detection. The detector (51) detects whether there is a target product, the relevant distance and trajectory. If there is interference between the target product and the product in front, the two first driving devices and two rotating wheels (36) make the two baffles (32) rotate inward so that the two baffles (32) are parallel, thereby causing the target product to stop for a corresponding time. After the target product moves to the detection position, the second sensor (47) collects the height data of the target product, while the first sensor (45) collects the motion data of the target product. The third step is preliminary identification. The industrial camera (44) will collect the overall image of the target product and record it as a preliminary target image. The preliminary target image will be analyzed and it will be determined which position on the preliminary target image is blurred. At the same time, based on the motion data, the moving plate (4) and the industrial camera (44) will move synchronously with the target product through the third drive device, the second transmission box (54), the second lead screw (55) and the second nut seat (56). Step 4: Accurate identification. Based on the analysis and judgment results of the preliminary target image, the second drive device, the first transmission box (12), the first lead screw (15) and the first nut seat (14) are used to move the movable box (5), the moving plate (4) and the industrial camera (44) to the corresponding positions. Through the relevant height data, the moving plate (4) and the industrial camera (44) are lowered to the appropriate position through the lifting device. The industrial camera (44) will collect the local images of the relevant local areas in the target product and record them as accurate images. Step 5: Repeat step 4 to acquire accurate images of all blurred areas of the target product on the initial target image; Step 6: Analysis and Modeling. Based on the preliminary target image and the precise image, construct the target image model of the target product, and analyze and recognize the target image model to complete the image recognition of the target product.
