Not only is there a defect of low efficiency, but there is also a large error in the clothing pattern paper, which leads to a large error in the size of the clothing when it is made according to the clothing pattern paper.

DETAILED DESCRIPTION
[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0046] See also Figure 1-15 , an automatic clothing design system based on image recognition, comprising a workbench 1, a loading board 2 for placing samples is fixedly connected to the workbench 1, the loading board 2 is made of a transparent material, preferably a transparent glass material, a camera 3 for collecting sample contour data is fixedly connected to the top of the loading board 2 through a bracket, and the camera 3 transmits the collected sample contour (rough contour) to a database of an external controller, a display screen 4 for emitting light is fixedly connected to the bottom of the loading board 2 and located on the workbench 1, the display screen 4 is electrically connected to the external controller, and the external controller controls the display screen 4 to emit light of different colors, so that the light emitted by the display screen 4 serves as the background color of the sample, and for the same sample display screen 4 Different background colors can be continuously switched, so that the camera 3 can obtain an image with a large color difference between the background color and the sample, which is conducive to analyzing and identifying the outline of the sample. When the light emitted by the display screen 4 has a large color difference with the sample color (for example, the emitted light is white, and the color of the sample is black), it is conducive to collecting the sample outline. In addition, the display screen 4 itself can also display the electronic sample outline stored in the external controller (for example, drawn by two-dimensional software such as CAD). A first beam 5 is connected to the workbench 1 for horizontal sliding above the carrier plate 2, and a first moving block 6 is connected to the first beam 5 for longitudinal sliding. A double-headed laser 7 for emitting two parallel laser beams is rotatably connected to the side wall of the first moving block 6. The double-headed laser 7 is driven to rotate by a first motor 8. Figure 6-7As shown, the first motor 8 is fixedly connected to the first moving block 6, and the output shaft of the first motor 8 is connected to the side wall of the double-headed laser 7 through tooth meshing. When the first motor 8 is started, the output shaft of the first motor 8 drives the double-headed laser 7 to rotate, thereby adjusting the angles of the two laser beams emitted by the double-headed laser 7. The first motor 8 uses a servo motor that can accurately control the rotation angle and can feed back the numerical value of the rotation angle to the controller, so that the position data of the connection line of the two laser beams emitted by the double-headed laser 7 can be obtained in real time.
[0047] A photoelectric panel 9 for sensing laser signals is provided between the object carrier 2 and the display screen 4. The photoelectric panel 9 is driven to slide by a cylinder 10. Figure 4-5 As shown, a storage groove 22 is provided on one side of the workbench 1 located on the carrier plate 2, and the cylinder 10 is fixedly connected to the lower side of the workbench 1, and the output shaft of the cylinder 10 is fixedly connected to the side wall of the photoelectric panel 9. When the cylinder 10 is started, the output shaft of the cylinder 10 can drive the photoelectric panel 9 to be stored in the storage groove 22. At this time, the display screen 4 is directly below the carrier plate 2 (without obstacles in the middle), and the output shaft of the cylinder 10 can also drive the photoelectric panel 9 to slide between the carrier plate 2 and the display screen 4. The photoelectric panel 9 is a photosensitive element. When the laser irradiates the photoelectric panel 9, an electrical signal will be generated, and when different numbers of lasers irradiate the photoelectric panel 9, the amplitude of the electrical signal fed back to the controller is different, so that it can be identified whether there is one or two laser beams for irradiation, and then the contour data can be corrected. With this structure, the photoelectric panel 9 does not need to be able to identify the conversion of photoelectric signals at different positions and regions, but only considers the intensity of the electrical signal conversion, thereby greatly reducing the requirements for the photoelectric panel 9, and a general solar panel can do the job.
[0048] After obtaining the size outline of the sample clothing, in order to facilitate the production (cutting or drawing) of the clothing pattern based on the outline data, the workbench 1 is provided with an operating surface 11 on one side of the loading plate 2, and a second beam 12 is slidably connected to the workbench 1 above the operating surface 11, and a second moving block 13 is slidably connected to the second beam 12 in the longitudinal direction. The controller controls the second beam 12 and the second moving block 13 to move along the contour track of the sample respectively, and a lifting plate 14 is slidably connected to the second moving block 13, and the lifting plate 14 is driven to slide by a second motor 15, such as Fig. 9 The second motor 15 is fixedly connected to the second moving block 13, and a screw is connected to the output shaft of the second motor 15, and the screw is meshed with the lifting plate 14. When the second motor 15 drives the screw to rotate, the lifting plate 14 moves up and down with the rotation of the screw. A laser cutter 16 is fixedly connected to the lifting plate 14. After the laser cutter 16 is lifted and lowered with the lifting plate 14, the distance between the laser cutter 16 and the cardboard can be adjusted, and then the focal length of the cutting laser can be adjusted.
[0049] In order to realize that the device can automatically draw lines on the cardboard according to the shape of the sample with chalk, a line drawing device 17 is also provided on the lifting plate 14, and the line drawing device 17 includes a fixed sleeve 1701, the fixed sleeve 1701 is fixedly connected to the lifting plate 14, and the fixed sleeve 1701 is internally slidably connected with a sliding sleeve 1702 for containing chalk, and the sliding sleeve 1702 slides inside the fixed sleeve 1701 through a solenoid valve 1703, and the solenoid valve 1703 is fixedly connected to the lifting plate 14, and the output shaft of the solenoid valve 1703 is connected to the sliding sleeve 170 2, and elastic sheets 1704 are provided on both sides of the fixing sleeve 1701, and the upper ends of the two elastic sheets 1704 are connected to the lifting plate 14, and the lower ends of the elastic sheets 1704 are provided with arc-shaped bending positions, which penetrate the side walls of the fixing sleeve 1701 and the sliding sleeve 1702 to fix the chalk clamp, and the side walls of the fixing sleeve 1701 are rotatably connected with supporting plates 1705, and the side walls of the supporting plates 1705 are rotatably connected with telescopic rods 1706, and the upper ends of the telescopic rods 1706 are rotatably connected to the side walls of the sliding sleeve 1702.
[0050] like Fig.14 The telescopic rod 1706 shown is composed of an upper rod, a plug-in rod, a buffer spring, and a lower rod. The upper rod and the plug-in rod are fixedly connected, and the lower end of the plug-in rod is movably plugged into the lower rod. The two ends of the buffer spring are respectively connected to the upper rod and the lower rod. Such a structure allows the support plate 1705 to rotate and merge first, and then the upper rod can still follow the sliding sleeve 1702 to move downward without any hindrance.
[0051] The side walls of the sliding sleeve 1702 and the fixed sleeve 1701 are provided with grooves, and the grooves on the side walls of the sliding sleeve 1702 are longer than the grooves on the fixed sleeve 1701 (which is beneficial for the sliding sleeve 1702 to slide downward, so that the support plate 1705 rotates and merges first and then the elastic sheet 1704 clamps the chalk; and also beneficial for the sliding sleeve 1702 to slide upward, so that the elastic sheet 1704 clamps the chalk first and then the support plate 1705 rotates and opens);
[0052] When in use, when the elastic sheet 1704 is in a relatively close state, the chalk is placed inside the sliding sleeve 1702, and the sliding sleeve 1702 is driven to slide downward by the electromagnetic valve 1703. At this time, the sliding sleeve 1702 first drives the support plate 1705 to rotate through the telescopic rod 1706, and the support plate 1705 rotates to the position as shown in the figure. Fig. 9The sliding sleeve 1702 is in the state shown, and then the sliding sleeve 1702 continues to slide (the telescopic rod 1706 is continuously compressed), and the side wall of the sliding sleeve 1702 squeezes out the elastic sheet 1704 (when the grooves of the sliding sleeve 1702 and the fixed sleeve 1701 are staggered), so that the elastic sheet 1704 eliminates the obstruction of the chalk to the chalk. At this time, the chalk will fall downward and its bottom will be pressed on the supporting plate 1705. Then, the solenoid valve 1703 is used to drive the sliding sleeve 1702 to slide upward (the telescopic rod 1706 is continuously extended, and the position of the supporting plate 1705 remains unchanged). At this time, the sliding sleeve 1702 is aligned with the grooves of the fixed sleeve 1701, so that the elastic sheet 1704 is deformed so that the arc-shaped bent position is inserted into the interior of the sliding sleeve 1702 and the chalk is clamped. As the sliding sleeve 1702 continues to slide upward, the sliding sleeve 1702 will pull the supporting plate 1705 to open to the state shown in the figure. Figure 8 In the state shown, the end of the chalk is in a state of extending downward for a certain length, and the lifting plate 14 is moved downward by the second motor 15, so that the lower end of the chalk is attached to the model drawing board, and the movement of the chalk is realized under the cooperation of the second crossbeam 12 and the second moving block 13, and then the line drawing operation is completed. When the above operation is repeated for a period of time, the chalk moves downward to make up for the length of the chalk loss;
[0053] In order to make the chalk exhausted, it is possible to replenish chalk in the interior of the sliding sleeve 1702 in time, such as Fig.10 As shown, a contact piece 21 is provided on the side wall of the fixing sleeve 1701. The contact piece 21 is a switch of an external alarm device. When the contact piece 21 is subjected to pressure, the alarm device sounds an alarm. Therefore, the contact piece 21 can be a pressure sensor, such as Fig.13 As shown, when the elastic sheet 1704 holds the chalk, the elastic sheet 1704 will not contact the contact sheet 21. When the chalk is consumed more, it will be lowered again. Fig.12 As shown, when the chalk is shorter, the elastic sheet 1704 cannot clamp the chalk. At this time, the elastic sheet 1704 will contact the contact sheet 21, and then trigger the alarm device to alert the operator to add chalk to the inside of the sliding sleeve 1702.
[0054] Specifically, in order to allow the chalk to maintain a certain downward pressure when drawing lines, the elastic sheet 1704 is connected to the lifting plate 14 through the fixing sheet 23, and a downward pressure spring 24 is connected between the upper end of the elastic sheet 1704 and the fixing sheet 23, and the lower side of the fixing sheet 23 is provided with a positioning column 25 that passes through the upper end of the elastic sheet 1704, and both sides of the positioning column 25 are in active contact with the touch points 26 provided on the lower side of the upper end of the elastic sheet 1704.
[0055] like Fig.13As shown in the figure, when the elastic sheet 1704 clamps the chalk to draw a line, in order to make the chalk draw clearly, the lifting plate 14 is lowered to drive the chalk down. At this time, the chalk is forced to drive the elastic sheet 1704 upward to press the pressing spring 24 to compress it (as shown in the figure). Fig.13 There is a certain distance between the arc-shaped bending position of the elastic sheet 1704 and the grooves on the side walls of the sliding sleeve 1702 and the fixed sleeve 1701. This distance is equal to the distance that the lifting plate 14 descends each time). At this time, stable line drawing can be performed by moving the second crossbeam 12 and the second moving block 13. As the chalk is continuously consumed, the positioning column 25 and the touch point 26 implement signal triggering (the downward pressure spring 24 has an elastic tendency to allow the positioning column 25 to contact the touch point 26). At this time, the controller allows the second motor 15 to run to drive the lifting plate 14 to descend, allowing it to move down again to press the spring. 24 deformation distance, and this is repeated until the sum of the distances of the lifting plate 14 descending multiple times is close to or equal to the length of the chalk extending out of the fixed sleeve 1701 (this length depends on the distance between the support plate 1705 and the fixed sleeve 1701, which is fixed and known), and then the above-mentioned operation process of extending the chalk again can be performed. Therefore, with the cooperation of the above-mentioned structure, the elastic sheet 1704 not only plays the role of clamping the chalk, but also has the function of maintaining sufficient downward pressure when the chalk is used for calligraphy and painting, and also has the function of judging when the chalk needs to be extended out of the fixed sleeve 1701 again.
[0056] In addition, when in Fig.13 When adding chalk to the tray 1705, the remaining chalk will remain on the tray 1705, so the newly installed chalk cannot be extended smoothly. By utilizing the cooperation of the downward pressure spring 24, the positioning column 25, and the touch point 26, when the tray 1705 is opened, the chalk cannot be extended smoothly and will not touch the operating surface 11, so the touch point 26 will be triggered, allowing the lifting plate 14 to continue to descend until the above-mentioned "repeat this until the total distance of the lifting plate 14 descending multiple times is close to or equal to the length of the chalk extending out of the fixed sleeve 1701" is triggered, and the operation process of extending the chalk again can be carried out, that is, the entire pen-changing drawing process is automated.
[0057] In order to flatten and fix the sample on the carrier plate 2, specifically, a pressing plate 18 for pressing the sample is provided on the carrier plate 2, and the pressing plate 18 is made of a transparent material, and the material of the pressing plate 18 is preferably a transparent glass material. The workbench 1 is slidably connected to a third beam 19 on one side of the carrier plate 2, and an electric push rod 20 is fixedly installed on the third beam 19. The lower end of the output shaft of the electric push rod 20 is fixedly connected to one side of the pressing plate 18 to drive the pressing plate 18 to move up and down;
[0058] like Figure 4-5As shown, after placing the sample on the loading plate 2, the third crossbeam 19 is driven to slide to the right, and then the third crossbeam 19 slides to the right with the pressing plate 18, so that the pressing plate 18 moves to the top of the loading plate 2. At this time, the electric push rod 20 is started, so that the output shaft of the electric push rod 20 slides downward, so that the pressing plate 18 slides downward and fixes the sample on the loading plate 2. After the sampling is completed, the electric push rod 20 is started, so that the pressing plate 18 moves upward and loses contact with the sample. At this time, the third crossbeam 19 is driven to slide to the left with the pressing plate 18, so as to facilitate the removal of the sample.
[0059] Specifically, the first crossbeam 5 , the first moving block 6 , the second crossbeam 12 , and the second moving block 13 are all driven by different servo motors, so as to be able to move with controllable displacement.
[0060] Since the sample image acquired by camera 3 is an image diverging from a point, even if multiple cameras 3 are placed for multi-point sampling, there will still be deviations from the actual clothing contour due to point vision. Moreover, different clothing samples have different sizes, and it is impossible to arrange the position of camera 3 according to the contour of the sample. Especially for some thick clothing samples, the deviation of point vision will be greater. In order to improve the accuracy of sample contour acquisition, a recognition method for an automated clothing design system based on image recognition is proposed.
[0061] M1, the garment sample is placed on the carrier plate 2;
[0062] M2, the camera 3 obtains image information D1 by photographing the garment sample, and inputs the image information D1 to the controller,
[0063] Specifically, the photoelectric panel 9 is moved out from between the display screen 4 and the sample carrier plate 2, so that the display screen 4 is directly below the sample carrier plate 2, and the display screen 4 sequentially projects light of different colors upward to serve as the background color of the sample, and the camera 3 takes a picture of the sample from a point above the sample and transmits the image data to the controller for contour analysis;
[0064] M3, the controller performs sorting and calculation on the image information D1.
[0065] Specifically, since the background color emitted by the display screen 4 is known, the controller can remove all colors of the corresponding background colors in the corresponding image, and then summarize them to obtain the contour data A1. For example, if 10 background colors are changed and 10 pictures are taken, the controller automatically identifies and calculates the 10 pictures, deletes all colors of the corresponding background colors in each picture, and then binarizes the image and overlaps the multiple processed images to obtain the binarized contour data A1.
[0066] In addition, when the controller deletes the background color of the image, it can deduct within the range of plus or minus 20% of the background color gamut to avoid the problem of deviation caused by the difference between the sample color and the background color emitted by the display screen 4. Of course, the number of images and background colors can also be increased to improve accuracy.
[0067] M4, the photoelectric panel 9 moves between the carrier plate 2 and the display screen 4. As a photoelectric device, the photoelectric panel 9 can generate an electrical signal when receiving light. A specific laser can be used to cooperate with the photoelectric panel 9, so that the electrical signal generated by the photoelectric panel 9 can be used to determine whether the laser is irradiated on the photoelectric panel 9;
[0068] M5, the controller drives the first beam 5 and the first moving block 6 to move according to the following steps according to the sample profile data A1,
[0069] M51, the photoelectric panel 9 moves to between the carrier plate 2 and the display screen 4, the double-headed laser 7 emits two laser beams vertically downward and moves along with the first beam 5 and the first moving block 6,
[0070] During the movement, the contour data A1 is decomposed into point data according to the following principle, that is, the rotation angle of the double-headed laser 7, the moving paths of the first beam 5 and the first moving block 6 keep the two laser beams located on both sides of the contour, and the two sides are equidistant, and at the same time, the connection direction of the two laser beams is the standard of the normal direction of the corresponding point in the contour data A1.
[0071] M52, during the movement, the double-headed laser 7 emits two laser beams vertically downward, and the photoelectric panel 9 feeds back the received light signal to the controller. After moving the double-headed laser 7 according to the sample contour data A1, since the photoelectric panel 9 will generate different electrical signals after receiving different numbers of lasers, the three results will cause the photoelectric panel 9 to generate three different electrical signals, that is, the two laser beams irradiated by the double-headed laser 7 will allow the photoelectric panel 9 to recognize and generate three results, which are: ①, one laser beam irradiates the photoelectric panel 9, and one laser beam irradiates the sample; ② Both laser beams irradiate the photoelectric panel 9; ③, both laser beams irradiate the sample, and result ① is a structure in which the sample contour is between the two laser beams, which is the best irradiation result; when results ② and ③ are generated, the first beam 5 and the first moving block 6 move, so that the photoelectric panel 9 generates an electrical signal of result ①, that is, the laser irradiation result is corrected to result ①, and then the coordinates of the midpoint of the line connecting the two laser beams are used as the updated data, namely, the coordinate data B1.
[0072] In this way, the photoelectric panel 9 only needs to be used to feedback a few photoelectric signals, and there is no need to accurately determine the specific position on the photoelectric panel 9 irradiated by the laser. The contour data can be corrected in conjunction with the previous contour, thereby improving the sensitivity. In this way, the selection requirements for the photoelectric panel 9 will be much broader, thereby reducing the application cost and improving the application prospects.
[0073] Taking into account the deviation of image recognition caused by point light source, it is preferred to move the double-headed laser 7 to the inside of the contour while keeping the connection line of the two laser beams in the normal direction of the original data point (the direction of movement can also be based on the direction of the connection line between the projection point of the camera position on the carrier plate 2 and the decomposition point). If result ① cannot be achieved, move the first beam 5 and the first moving block 6 separately until result ① is achieved.
[0074] M6, the double-headed laser 7 moves the entire contour under the action of the first beam 5 and the first moving block 6, and the first motor 8, and collects all the coordinate data B1 to form a correction set;
[0075] M7, the controller collects and summarizes the coordinate data B1 to form a correction set, combines it with the contour data A1 to correct it to obtain the garment sample contour data A2, transmits it to the database of the external controller, and replaces the old data for storage.
[0076] In addition, in order to improve the overall recognition speed and accuracy at the same time, the double-headed laser 7 can be in a form where the distance between the two parallel laser beams is adjustable. For example, in the initial state, the distance between the two parallel laser beams adopts a larger value, such as L1, and the sample contour data A2 is obtained according to the above process. Then, based on the sample contour data A2, the distance between the two parallel laser beams is reduced to, for example, L2, and the above process is repeated to obtain more accurate sample contour data A3. If higher requirements are met, the distance can be continuously reduced and the above process can be repeated.
[0077] Working principle: when in use, place the sample on the carrier plate 2, and drive the pressing plate 18 to move and press on the carrier plate 2 through the third crossbeam 19 and the electric push rod 20 to fix the sample, and drive the photoelectric panel 9 to move out from between the display screen 4 and the carrier plate 2 through the oil cylinder 10, so that the display screen 4 is directly below the carrier plate 2, and the display screen 4 sequentially projects light of different colors upward to serve as the background color of the sample. Under different background colors, the sample is then photographed by the camera 3 to collect contour information, and the camera 3 inputs the contour information collected under different background colors into the external controller, and then the photoelectric panel 9 is moved between the carrier plate 2 and the display screen 4 through the oil cylinder 10. The external controller drives the first crossbeam 5 and the first moving block 6 to move according to the sample contour information, causing the double-headed laser 7 to move according to the sample contour trajectory, and then corrects the sample contour data;
[0078] When cutting is required, the controller controls the laser cutter 16 to start, and the external controller controls the second beam 12 and the second moving block 13 to start with a delay, so as to accurately cut the clothing pattern; line drawing operation can also be performed, and the line drawing operation has the same steps as the cutting operation.
