Description

Technical Field

[0001] The present invention belongs to the technical field of clothing detection equipment, and specifically relates to a clothing inspection system and equipment based on visual recognition. Background Art

[0002] With the progress and development of technology, in the clothing production industry, the manual inspection method of clothing has been unable to meet the clothing inspection requirements due to defects such as low efficiency, frequent occurrence of missed inspections and misjudgments.

[0003] Visual recognition technology is a technology based on computer vision. By processing and analyzing images, it can realize the automatic recognition, positioning, measurement and judgment of target objects. In clothing quality inspection, visual recognition technology can quickly identify and detect the sewing quality, color, labels, defects, etc. of clothing itself. Due to the advantages of high efficiency, accuracy, objectivity, traceability, and labor saving of visual recognition technology, visual recognition technology has received high praise in clothing inspection operations. When using visual recognition technology to detect the whole clothing, since the clothing itself is a three-dimensional structure, especially for high-end clothing such as suits and dress pants, the performance requirements for the pattern, comfort, etc. are relatively strict. Therefore, during visual recognition inspection, a three-dimensional support structure is usually required. After simulating the wearing of suits, dress pants and other clothing, visual recognition inspection is carried out to achieve a mutually promoting detection effect.

[0004] For example, a multi-airbag collaborative flexible three-dimensional clothes hanger for clothing visual detection is disclosed in the related technology, with the application number CN2011101181091. In this solution, by using a three-dimensional clothes hanger and an airbag group installed on the three-dimensional clothes hanger, the clothing is supported, and combined with a visual detection system to realize the intelligent detection of clothing. Since this solution can well imitate the wearing effect of people to support the clothing three-dimensionally, the visual detection system can not only detect defects such as clothing defects and poor seams, but also detect size defects, improving clothing quality and labor efficiency. However, it is found in the actual clothing production inspection process that compared with upper body clothing, since clothing such as pants is mostly in a moving state during wearing, the use of a static filling detection method will result in too one-sided detection results and insufficient comprehensive detection of clothing quality.

[0005] In view of this, the present invention proposes a clothing inspection system and equipment based on visual recognition to solve the above technical problems. Summary of the Invention

[0051] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0052] As Figures 1 to 8 shown, a clothing inspection system based on visual recognition according to the present invention includes a visual recognition module, a data processing module and a dynamic simulation module;

[0053] The visual recognition module collects clothing pictures through machine vision;

[0054] The visual recognition module includes an image acquisition unit and an image recognition unit;

[0055] The image acquisition unit is used to take pictures of clothing, and the image acquisition unit is composed of one of an industrial camera and a scanner. When acquiring clothing pictures, multiple industrial cameras or scanners that make up the image acquisition unit take pictures of the clothing from multiple angles, and the shooting range covers the whole clothing;

[0056] The image recognition unit receives the pictures taken by the image acquisition unit, recognizes and segments the clothing in the pictures, and reduces the picture area. Since the shooting range is larger than the clothing area, there is a lot of irrelevant content in the captured clothing pictures. Recognizing and segmenting the captured clothing pictures can remove the irrelevant content to reduce the difficulty of subsequent picture processing;

[0057] The data processing module is used to receive the collected clothing pictures, perform denoising and enhancement processing on the clothing pictures, and finally compare the clothing pictures with the standard clothing pictures, and finally output the comparison result;

[0058] The data processing module includes an image processing unit, an image analysis unit and a data management unit;

[0059] The image processing unit receives the clothing pictures refined by the image recognition unit, and performs denoising and enhancement on it to improve the image quality. After performing denoising and enhancement processing on the clothing pictures, the clarity of the pictures will be improved, which is convenient for subsequent analysis;

[0060] The image analysis unit is used to analyze the processed clothing pictures, compare them with the standard pictures, and mark the defective parts. When analyzing and processing the pictures, it is necessary to first scan the captured clothing pictures, and compare and identify the pictures with the standard clothing pictures and standard defect pictures stored in the data management unit, and mark the defective parts in the captured clothing pictures according to the recognition results;

[0061] The data management unit is used to store the pre-edited standard clothing pictures and standard defect pictures. The standard clothing pictures and standard defect pictures stored in the data management unit are used to provide comparison templates and provide data support for the image analysis unit. Their sources are the pictures of defect-free clothing and standard defect pictures collected by the staff;

[0062] The dynamic simulation module simulates the motion state by changing the clothing posture;

[0063] The dynamic simulation module includes a mounting table 1, a simulation prosthetic limb 11 and a traction mechanism;

[0064] The simulation prosthetic limb 11 and the traction mechanism are both installed on the mounting table 1;

[0065] The simulated prosthesis 11 is used to wear clothing. The simulated prosthesis 11 is composed of a skeleton and a shaping layer. The shaping layer is made of elastic material. The shaping layer is used to simulate the appearance of the prosthesis. The shaping layer is wrapped on the outside of the skeleton. The simulated prosthesis 11 as a whole is composed of a skeleton and a shaping layer. The two are detachably connected. When matching different types of clothing, different types of simulated prostheses 11 are used. Clothing is worn on the simulated prosthesis 11, which can more clearly simulate the wearing condition of clothing on the human body. By cooperating with the traction mechanism and changing the posture of the simulated prosthesis 11, the wearing condition of clothing during human movement can be simulated, thereby assisting the visual recognition module to capture clothing details;

[0066] The traction mechanism is used to drive the artificial limb 11 to simulate human body movement on the mounting platform 1 .

[0067] As a preferred embodiment of the present invention, the traction mechanism includes a connecting seat 2 and a longitudinal telescopic rod 21;

[0068] The simulation prosthesis 11 is hinged in sequence by the waist and hip part, the thigh part and the calf part, the calf part is arranged in a plane at one end away from the thigh part, and the connecting seat 2 is connected to the bottom end of the calf part. The clothing used for testing in the present invention is a trousers product. After the trousers are worn on the simulation prosthesis 11, in order to facilitate the simulation of the movement state of the lower limbs of the human body, the mutually hinged waist and hip part, the thigh part and the calf part are used, so that the simulation prosthesis 11 can simulate the movement of walking and the like;

[0069] The mounting platform 1 is provided with symmetrically arranged movable grooves 12 , in which longitudinal telescopic rods 21 are installed. The longitudinal telescopic rods 21 are made of electric telescopic rods, and the connecting seat 2 is connected to the longitudinal telescopic rods 21 .

[0070] The movable grooves 12 are all T-shaped in design, and a transverse telescopic rod 22 is also installed in the movable groove 12. The transverse telescopic rod 22 is connected to the connecting seat 2. The transverse telescopic rod 22 is used to drive the connecting seat 2 to move laterally. In the present invention, the longitudinal telescopic rod 21 and the transverse telescopic rod 22 are both electric telescopic rods, and the movement states of the longitudinal telescopic rod 21 and the transverse telescopic rod 22 are controlled by a pre-installed controller.

[0071] The longitudinal telescopic rod 21 and the transverse telescopic rod 22 are both fixedly installed with insertion plates 23. The insertion plates 23 are perpendicularly arranged with the corresponding longitudinal telescopic rod 21 and transverse telescopic rod 22. A slot 24 is formed at the bottom surface of the connecting seat 2. The slot 24 is a T-shaped structure. In the initial state, the connecting seat 2 is located at the center of the movable slot 12, and the insertion plates 23 are all located within the slot 24. The settings of the slot 24 and the insertion plates 23 are used to flexibly connect the connecting seat 2 with the longitudinal telescopic rod 21 and the transverse telescopic rod 22. It should be noted that when the connecting seat 2 switches between transverse movement and longitudinal movement, it needs to be in the initial position. When the connecting seat 2 performs transverse movement, as the connecting seat 2 gradually moves away from the initial position, the insertion plate 23 on the longitudinal telescopic rod 21 will gradually separate from the connecting seat 2. And when the connecting seat 2 performs longitudinal movement, as the connecting seat 2 gradually moves away from the initial position, the insertion plate 23 on the transverse telescopic rod 22 will gradually separate from the connecting seat 2.

[0072] In the initial state, both calf parts of the simulation prosthetic limb 11 are vertically placed on the connecting seat 2. At this time, the connecting seat 2 is located at the center of the movable slot 12. The mutually perpendicular transverse telescopic rod 22 and longitudinal telescopic rod 21 are both connected to the connecting seat 2 through the insertion plates 23 and the slots 24. During the inspection process, the longitudinal telescopic rod 21 and the transverse telescopic rod 22 are controlled by a pre-written control program. When the simulation prosthetic limb 11 performs a walking simulation, the longitudinal telescopic rods 21 in the two movable slots 12 move in the opposite direction, thereby causing the two connecting seats 2 to move in the opposite direction. And the calf parts connected to the connecting seat 2 move forward and backward respectively. When simulating movements such as splits, when the connecting seat 2 is in the initial position, the transverse telescopic rod 22 drives the insertion plate 23 and the connecting seat 2 to perform transverse movement. During the process of the posture change of the simulation prosthetic limb 11, the trousers worn on the simulation prosthetic limb 11 change their postures accordingly. During this process, the image acquisition unit continuously takes multi-angle photos of the trousers worn on the simulation prosthetic limb 11. On the one hand, the movement of the simulation prosthetic limb 11 causes the positions and angles of various parts of the trousers to change, resulting in an increase in the information covered by the pictures taken by the image acquisition unit, thereby enhancing the probability of detecting defects. On the other hand, when the simulation prosthetic limb 11 drives the trousers to perform a simulation, under the action of the movement force, some defects that are not obvious in appearance will be detected, such as phenomena like insecure sewing, etc., thereby further enhancing the detection efficiency of defects. At the same time, in cooperation with the pressure sensors installed on the simulation prosthetic limb 11, when collecting the pressure conditions of various parts of the simulation prosthetic limb 11 during the movement after wearing the trousers, it can assist in detecting the quality of the trousers on the one hand, and can also provide data for the subsequent design improvement of the trousers on the other hand.

[0073] As a preferred embodiment of the present invention, a switching mechanism is further included, and the switching mechanism is used to switch the clothing worn on the simulation prosthesis 11 to realize the assembly line operation of clothing inspection. The switching mechanism includes a mounting frame 25 and an assembly rod 27. When testing batch clothing, in order to speed up the convenience and efficiency of clothing inspection, it is necessary to optimize the combination process of clothing and the simulation prosthesis 11 to realize the assembly line operation of clothing inspection;

[0074] The cross section of the mounting frame 25 is an I-shaped structure, and a lifting slot 26 is provided at the top of the mounting frame 25. The assembly rod 27 is slidably mounted on the top of the mounting frame 25 through the lifting slot 26. The top of the artificial limb 11 is fixedly connected to the bottom of the assembly rod 27. The mounting frame 25 is composed of two discs and a support in the middle, and the lifting slots 26 are arranged at equal intervals along the circumferential direction of the discs, so that multiple assembly rods 27 are installed on the mounting frame 25 to separate multiple artificial limbs 11 at equal distances.

[0075] The mounting platform 1 is embedded and installed at the bottom of the mounting frame 25, the assembly rod 27 corresponds to the mounting platform 1 one by one, and the simulation prosthesis 11 is installed between the mounting platform 1 and the assembly rod 27;

[0076] The bottom of the simulated prosthesis 11 is made of ferromagnetic material, and an electromagnet is embedded on the top of the connecting seat 2. The connecting seat 2 is magnetically connected to the simulated prosthesis 11. During motion simulation, the electromagnet is in an on state. At this time, the movement of the connecting seat 2 will directly drive the simulated prosthesis 11 to move. When wearing or taking off clothes, the electromagnet is in a power-off state, which is convenient for separating the bottom of the simulated prosthesis 11 from the connecting seat 2, thereby facilitating the staff to change clothes.

[0077] The switching mechanism also includes a stand 3, a circulation motor 31 and a control rail 32;

[0078] A rotation groove 33 is provided on the platform 3, and the mounting frame 25 is rotatably installed in the rotation groove 33. A circulating motor 31 is fixedly installed on the platform 3, and the output end of the circulating motor 31 is transmission-connected with the mounting frame 25. The circulating motor 31 is installed on the platform 3, and a transmission friction wheel is fixedly installed on the output end, and the friction wheel extends into the rotation groove 33 and is friction-transmission-connected with the mounting frame 25. When the circulating motor 31 rotates, the mounting frame 25 is synchronously driven to rotate, which will cause the positions of multiple simulated prostheses 11 on the mounting frame 25 to change regularly, thereby enabling the simulated prostheses 11 to switch between the clothing wearing and unwearing position and the image acquisition position. It should be noted that in other embodiments of the present invention, the output end of the circulating motor 31 can also be fixed as a transmission gear, and the side of the mounting frame 25 corresponding to the transmission gear is provided with evenly distributed tooth grooves, so that the circulating motor 31 is gear-transmission-connected with the mounting frame 25;

[0079] At the top of the bench 3, a control rail 32 with a ring design is fixedly installed. The top of the assembly rod 27 has a T-shaped design, and the assembly rod 27 is slidably installed on the control rail 32. The control rail 32 is used to control the lifting of the assembly rod 27.

[0080] The control rail 32 is fixed on the bench 3. When the mounting bracket 25 rotates, relative movement occurs between the control rail 32 and the mounting bracket 25, and the assembly rod 27 installed on the mounting bracket 25 moves synchronously.

[0081] During actual clothing detection, the staff is located at the clothing wearing and unloading station. As the circulating motor 31 drives the mounting bracket 25 to rotate regularly, when the simulation prosthesis 11 moves to the clothing wearing and unloading station, the assembly rod 27 follows the movement of the mounting bracket 25. During this stage, the control rail 32 gradually bends upward, causing the assembly rod 27 to gradually rise. The rising assembly rod 27 pulls the simulation prosthesis 11, making the simulation prosthesis 11 first return to the vertical state. Subsequently, as the assembly rod 27 continues to rise, the simulation prosthesis 11 is pulled, and at the same time, the electromagnet on the connecting seat 2 is powered off, causing the simulation prosthesis 11 to disengage from the connecting seat 2. At this time, it is convenient for the staff to replace the trousers on the simulation prosthesis 11. After the trousers are replaced, the mounting bracket 25 moves again. During this stage, the control rail 32 gradually bends downward, causing the assembly rod 27 and the simulation prosthesis 11 to gradually descend. At the same time, the electromagnet is powered on again to connect the connecting seat 2 and the simulation prosthesis 11. When the simulation prosthesis 11 moves to the image acquisition position, the traction mechanism drives the calf part of the simulation prosthesis 11 to move, thereby simulating the movement state of the clothing on the human body to perform image acquisition of the clothing.

[0082] The present invention improves the efficiency of clothing detection by arranging multiple simulation prostheses 11 and cooperating with the circulating motor 31 to drive the multiple simulation prostheses 11 to alternately change positions at the wearing and unloading station and the image acquisition station, so that the wearing and unloading of the clothing and visual recognition are carried out simultaneously. At the same time, the automatic separation and combination of the simulation prosthesis 11 and the connecting seat 2 can also reduce the convenience for the staff to wear and remove the clothing.

[0083] As a preferred embodiment of the present invention, a toothed ring 4 is fixedly installed on the bench 3, and planet gears 41 are fixedly installed on the bottom surface of the mounting table 1. The planet gears 41 are in meshing transmission with the toothed ring 4.

[0084] In the present invention, there are multiple image acquisition stations for clothing. When the mounting frame 25 rotates, the mounting table 1 mounted on the mounting frame 25 moves synchronously. At the same time, the planetary gear 41 at the bottom of the mounting table 1 generates relative movement with the toothed ring 4. Since the planetary gear 41 meshes with the toothed ring 4, the planetary gear 41 drives the mounting table 1 to rotate. The rotation of the mounting table 1 will cause the angle of the clothing to change, so that multiple image acquisition units mounted inside the mounting table 1 can collect the clothing from multiple angles.

[0085] As a preferred embodiment of the present invention, a hydraulic chamber is provided in the shaping layer. Uniformly distributed telescopic cylinders 53 are fixedly installed on the mounting frame 25. The inner cavity of the telescopic cylinder 53 is connected to the hydraulic chamber through a pipeline. A connecting plate 54 is fixedly installed on the assembly rod 27. One end of the telescopic cylinder 53 away from the mounting frame 25 is fixedly connected to the connecting plate 54.

[0086] In order to further improve the convenience of wearing and removing the dress pants, when the assembly rod 27 moves upward under the guidance of the control rail 32, the connecting plate 54 on the assembly rod 27 synchronously pulls the end of the telescopic cylinder 53 away from the mounting frame 25. In the present invention, the telescopic cylinder 53 is composed of a fixed end and a moving end, and a cavity with a changing volume is formed between them. When the moving end of the telescopic rod is pulled by the connecting plate 54 and moves upward, the inner cavity volume of the telescopic cylinder 53 increases, and a negative pressure is generated in the telescopic cylinder 53. The negative pressure acts on the hydraulic chamber inside the shaping layer through the pipeline, so that the fluid in the hydraulic chamber flows into the telescopic cylinder 53, the volume of the shaping layer shrinks, and the gap between the simulation prosthetic limb 11 and the dress pants increases, making it easier to wear or remove the dress pants. After the dress pants are replaced, as the assembly rod 27 descends, the telescopic cylinder 53 resets, so that the fluid in the telescopic cylinder 53 flows back into the shaping layer until the shaping layer expands to fix the dress pants.

[0087] As a preferred embodiment of the present invention, the switching mechanism further includes a pre-connection ring 5. The pre-connection ring 5 is a ring-shaped structure. Uniformly distributed spring clips 51 are fixedly installed on the pre-connection ring 5. The spring clips 51 are used to fix the clothing. A magnetic attraction ring 52 is fixedly installed at the top of the simulation prosthetic limb 11. The magnetic attraction ring 52 is used to fix the pre-connection ring 5.

[0088] The presence of the pre-connection ring 5 facilitates the pre-installation of the dress pants by the staff during the gap when wearing the dress pants on the simulation prosthesis 11. During pre-installation, the spring clip 51 is used to clamp the top opening of the dress pants, causing the top opening of the dress pants to be fixedly opened. When wearing the dress pants on the simulation prosthesis 11, the staff manually pushes the rigid pre-connection ring 5 upward, causing the pre-connection ring 5 to contact the magnetic attraction ring 52, thereby realizing the wearing of the dress pants. Compared with the soft dress pants, using the pre-connection ring 5 to expand the opening of the dress pants can effectively enhance the wearing convenience of the dress pants. At the same time, the magnetic attraction between the magnetic attraction ring 52 and the pre-connection ring 5 can also prevent the dress pants from falling off under the influence of gravity after wearing, and cooperate with the expansion of the shaping layer to achieve the fixation of the dress pants. It should be noted that the magnetic attraction intensity of the magnetic attraction ring 52 on the pre-connection ring 5 is greater than the total weight of the pre-connection ring 5 and the dress pants.

[0089] A clothing inspection device based on visual recognition, the inspection device includes a clothing inspection system, and the clothing inspection device further includes a detection board 6. The detection board 6 is fixedly installed on the bench 3. The detection boards 6 are arranged in plurality, and the image acquisition unit is installed on the detection board 6.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
