[0073] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0074] At present, when correcting the deviation of cloth, a correction sensor is used, but this type of alignment can only achieve rough alignment and cannot achieve precise alignment. In order to solve the above technical problems, the present invention provides a method for correcting the deviation of cloth, the core concept of which is to first obtain a cloth image taken by a camera, and determine the center point coordinates corresponding to a first position on the cloth according to the cloth image, and then determine the center point coordinates corresponding to a second position on the cloth, wherein the second position is the next position of the first position, and then determine the time when the first position and the second position arrive at the winding correction mechanism respectively, and finally adjust the position of the winding correction mechanism according to the time when the first position and the second position arrive at the winding correction mechanism, the center point coordinates corresponding to the first position, and the center point coordinates corresponding to the second position, so that the center point coordinates corresponding to the first position and the center point coordinates corresponding to the second position are determined according to the camera shooting, and the position of the winding correction mechanism is adjusted, and then the position of the cloth entering the winding correction mechanism is adjusted, so that the first position and the second position of the cloth can be accurately aligned.

[0075] Reference Figure 1 , shows a flowchart of the steps of a cloth deviation correction method provided by an embodiment of the present invention, the method is applied to a controller; the controller is respectively connected to the winding deviation correction mechanism of the camera, and the method may specifically include the following steps:

[0076] Step 101, obtaining a cloth image taken by the camera, and determining the coordinates of a center point on the cloth corresponding to a first position based on the cloth image.

[0077] In the embodiment of the present invention, Figure 2 As shown, a structural block diagram of a web-correcting device provided by an embodiment of the present invention is shown, a camera is provided above point E, point K is a winding web-correcting structure, and an encoder is provided above point G. The cloth can pass through points E, F, G, H, I, and J in sequence, and then reach the winding web-correcting mechanism at point K. The encoder is used to control the camera to collect images.

[0078] In the embodiment of the present invention, the camera can take a picture of point E in real time, the controller can obtain the cloth image taken by the camera, and then determine the coordinates of the center point on the cloth corresponding to the first position based on the cloth image.

[0079] In the present invention, the lateral resolution of the camera can reach 0.06mm, and the longitudinal resolution is consistent with the resolution of the encoder and is also 0.06mm. Through the collected cloth image, a roll of cloth is annotated with longitudinal coordinates according to the direction of cloth movement, and a point is selected as the starting point. The center point corresponding to the first position can be used as the starting point. According to customer needs, 0.06mm can be selected as the data recording interval, that is, in the direction of cloth movement, the coordinates of the two edges of the cloth and the coordinates of the alignment center point are calculated once every 0.06mm. If the speed is not fast, the interval can be modified to 10mm as needed to improve efficiency and reduce the amount of data.

[0080] like Figure 3 FIG. 1 is a schematic diagram of a camera shooting method provided by an embodiment of the present invention. The cloth in the picture taken by the camera is Figure 2 For the cloth at point E, since the camera is fixed, a coordinate system can be set in advance for the camera shooting configuration. Then, after the camera takes a picture of the cloth, the coordinates of both sides of the cloth can be determined.

[0081] In one embodiment, determining the coordinates of the center point corresponding to the first position on the cloth based on the cloth image may include: obtaining the first coordinate and the second coordinate corresponding to the first position on the cloth in the cloth image; the first coordinate and the second coordinate are respectively the two side coordinates corresponding to the first position on the cloth; and determining the coordinates of the center point corresponding to the first position on the cloth based on the first coordinate and the second coordinate corresponding to the first position on the cloth.

[0082] Specifically, Figure 3 For example, in the obtained cloth image, the first coordinate corresponding to the first position on the cloth is (X a1 , Y m1 ), the second coordinate is (X b1 , Y m1 ), the first coordinate and the second coordinate are the coordinates on both sides of the cloth corresponding to the first position, and then according to the first coordinate (X a1 , Y m1 ), and the second coordinate (X b1 , Y m1 ), the coordinates of the center point on the cloth corresponding to the first position are calculated as (X c1 , Y m1 ).

[0083] Step 102, determining the coordinates of the center point on the cloth corresponding to the second position; the second position is the next position of the first position.

[0084] In an embodiment of the present invention, after determining the coordinates of the center point corresponding to the first position on the cloth, the coordinates of the center point corresponding to the second position on the cloth can be determined. The second position can be the next position of the first position, and can also be understood as the corresponding center position in the next cloth image relative to the cloth image corresponding to the first position. The first position and the second position in the present invention both refer to the position of the cloth in the cloth image.

[0085] In one embodiment, determining the coordinates of the center point corresponding to the second position on the cloth may include: judging whether the second position on the cloth is damaged; when the second position on the cloth is not damaged, obtaining the third coordinate and the fourth coordinate corresponding to the second position on the cloth; the third coordinate and the fourth coordinate are the two side coordinates corresponding to the second position on the cloth, respectively; determining the coordinates of the center point corresponding to the second position on the cloth according to the third coordinate and the fourth coordinate corresponding to the second position on the cloth; when the second position on the cloth is damaged, determining the coordinates of the center point of the second position according to the coordinates of the center point corresponding to the first position on the cloth.

[0086] Specifically, when determining the center point coordinates corresponding to the second position on the cloth, the present invention will first determine whether the second position on the cloth is damaged. That is, it will first determine whether the cloth is damaged. When the second position on the cloth is not damaged, the center point coordinates corresponding to the second position can be determined in the same manner as described above.

[0087] For example: The third coordinate on the cloth corresponding to the second position is (X a2 , Y m2 ), the fourth coordinate is (X b2 , Y m2 ), the third and fourth coordinates are the coordinates on both sides of the cloth corresponding to the second position, and then according to the third coordinate (X a2 , Y m2 ), and the fourth coordinate (X b2 , Y m2 ), the coordinates of the center point on the cloth corresponding to the second position are calculated as (X c2 , Y m2 ).

[0088] For example, Figure 4 , which is a schematic diagram of a cloth position provided by an embodiment of the present invention, Figure 4 The first coordinate corresponding to the first position in is A 1n (X a1 , Y m1 ), the second coordinate is B 1n (X b1 , Y m1 ), then the coordinates of the center point corresponding to the first position can be calculated as C1n (X c1 , Y m1 ), the third coordinate corresponding to the second position is A 2n (X a2 , Y m2 ), the fourth coordinate is B 2n (X b2 , Y m2 ), then the coordinates of the center point corresponding to the second position can be calculated as C 2n (X c2 , Y m2 ), after calculation, the coordinates of the center point corresponding to the first position can be obtained as C 1n (X c1 , Y m1 ), the coordinates of the center point corresponding to the second position are C 2n (X c2 , Y m2 ), then the cloth corresponding to the second position is centered with the cloth corresponding to the first position.

[0089] For example, Figure 5 FIG. 1 is a schematic diagram showing another cloth position provided by an embodiment of the present invention. Figure 5 The first coordinate corresponding to the first position in is A 1n (X a1 , Y m1 ), the second coordinate is B 1n (X b1 , Y m1 ), then the coordinates of the center point corresponding to the first position can be calculated as C 1n (X c1 , Y m1 ), the third coordinate corresponding to the second position is A 2n (X a2 , Y m2 ), the fourth coordinate is B 2n (X b2 , Y m2 ), then the coordinates of the center point corresponding to the second position can be calculated as C 2n (X c2 , Y m2 ), after calculation, the coordinates of the center point corresponding to the first position can be obtained as C 1n (X c1 , Y m1 ), the coordinates of the center point corresponding to the second position are C 2n (X c2 , Y m2 ) are not the same, then the cloth corresponding to the second position is not centered with the cloth corresponding to the first position.

[0090] When damage occurs at the second position on the cloth, the coordinates of the center point of the second position can be determined based on the coordinates of the center point on the cloth corresponding to the first position.

[0091] In one embodiment, determining whether the cloth is damaged may include: determining the position where the cloth changes in width; determining that the cloth is damaged when the width change corresponding to the position where the cloth changes in width is within a preset range; and determining that the cloth is not damaged when the width change corresponding to the position where the cloth changes in width is not within the preset range.

[0092] Specifically, when the width of the cloth changes, it indicates that the cloth has changed. There are two possibilities. The first is that there is a new cloth and the position of the new cloth has changed from the position of the previous cloth. The second is that the edge of the cloth is damaged, so the width of the cloth has changed. However, the scope of cloth damage is generally small. When the width change corresponding to the position where the width changes in the layout is within the preset range, it can be determined that the cloth has been damaged. When the width change corresponding to the position where the width changes in the layout is not within the preset range, it can be determined that the cloth has not been damaged.

[0093] For example, Figure 4 and Figure 5 The width of the cloth has changed, but Figure 4 and Figure 5 If a new piece of cloth appears in the picture, the width change at the position where the cloth width changes must be outside the preset range. Then it can be determined that the cloth is not damaged, but a new piece of cloth has been replaced. Figure 6 FIG. 1 is a schematic diagram showing another cloth position provided by an embodiment of the present invention. Figure 6 The width of the cloth has changed, but after a short distance, the width change returns to the original width. Then the width change corresponding to the position where the width change of the cloth occurs is within the preset range. At this time, it can be determined that the cloth is damaged.

[0094] In one embodiment, the center point coordinates of a second position are determined based on the center point coordinates corresponding to the first position on the cloth, including: obtaining the first coordinate and the second coordinate corresponding to the first position on the cloth in the cloth image; the first coordinate and the second coordinate are the two side coordinates corresponding to the first position on the cloth, respectively; determining the center point coordinates corresponding to the first position on the cloth based on the first coordinate and the second coordinate corresponding to the first position on the cloth; determining the center point coordinates corresponding to the first position on the cloth as the center point coordinates of the second position.

[0095] Specifically, if Figure 6 As shown, a schematic diagram of another cloth position provided by an embodiment of the present invention is shown. Figure 6The first coordinate corresponding to the first position in is A 1n (X a1 , Y m1 ), the second coordinate is B 1n (X b1 , Y m1 ), then the coordinates of the center point corresponding to the first position can be calculated as C 1n (X c1 , Y m1 ), Figure 6 The second position in the figure is damaged. At this time, the third coordinate corresponding to the second position is A 2n (X a2 , Y m2 ), the fourth coordinate is B 2n (X b2 , Y m2 ), then the coordinates of the center point corresponding to the second position can be calculated as C 2n (X c2 , Y m2 ), but because the second position is damaged, it is obvious that the center point coordinates of the second position corresponding to the calculation are C 2n (X c2 , Y m2 ) is not the correct center coordinate corresponding to the second position, because the coordinates of the two sides of the cloth corresponding to the positions after the second position continue to be the same as the coordinates of the two sides corresponding to the first position, so the center coordinate C corresponding to the first position on the cloth can be 1n (X c1 , Y m1 ), which is determined as the center coordinate of the second position, that is, the correct center coordinate of the second position is C 2n (X c1 , Y m1 ).

[0096] Step 103, respectively determining the time when the first position and the second position arrive at the winding and correcting mechanism.

[0097] In the embodiment of the present invention, after determining the center coordinates on the cloth corresponding to the second position, the time when the first position and the second position arrive at the winding and correcting mechanism can be determined respectively.

[0098] In one embodiment, the time when the first position and the second position arrive at the winding and correcting mechanism is respectively determined, including: obtaining the distance between the first position and the winding and correcting mechanism; obtaining the shooting time corresponding to the first position and the second position respectively; obtaining the running speed of the winding and correcting mechanism; according to the distance between the first position and the winding and correcting mechanism, the shooting time corresponding to the first position and the second position respectively, and the running speed of the winding and correcting mechanism, the time when the first position and the second position arrive at the winding and correcting mechanism is respectively determined.

[0099] Specifically, the controller can first obtain the distance between the first position and the winding correction mechanism when taking the photo, and the distance is Figure 2 The sum of the distances from point E to point F, point F to point G, point G to point H, point H to point I, point I to point J, and point J to point K is the distance when the cloth in the corresponding area photographed by the camera runs to the winding and correcting mechanism, and then the corresponding shooting times of the first position and the second position are obtained, for example: the shooting time corresponding to the first position is 9:10:10, and the shooting time corresponding to the second position is 9:10:11.

[0100] Then, the running speed of the winding mechanism is obtained. Then, the running time of the cloth from point E to point K can be determined according to the distance between the first position and the winding and correcting mechanism and the running speed of the winding mechanism. For example, the running time from point E to point K is 5 seconds, so it can be determined that the time when the first position arrives at the winding and correcting mechanism is 9 hours, 10 minutes and 15 seconds, and the time when the second position arrives at the winding and correcting mechanism is 9 hours, 10 minutes and 16 seconds.

[0101] Step 104 , adjusting the position of the winding and correcting mechanism according to the time when the first position and the second position reach the winding and correcting mechanism, the center point coordinates corresponding to the first position, and the center point coordinates corresponding to the second position.

[0102] In an embodiment of the present invention, after respectively determining the time when the first position and the second position arrive at the winding and correcting mechanism, the position of the winding and correcting mechanism can be adjusted accordingly according to the time when the first position and the second position arrive at the winding and correcting mechanism, the center point coordinates corresponding to the first position, and the center point coordinates corresponding to the second position, so that the first position and the second position of the cloth can be accurately aligned.

[0103] In one embodiment, the position of the winding and correcting mechanism is adjusted according to the time when the first position and the second position reach the winding and correcting mechanism, the center point coordinates corresponding to the first position, and the center point coordinates corresponding to the second position, including: when the time from the current time to the first position to reach the winding and correcting mechanism is a preset time, the position of the winding and correcting mechanism is adjusted according to the center point coordinates corresponding to the first position; when the time from the current time to the second position to reach the winding and correcting mechanism is a preset time, the position of the winding and correcting mechanism is adjusted according to the center point coordinates corresponding to the second position.

[0104] Specifically, the preset time is 0.5 seconds, and the time when the first position arrives at the winding and correcting mechanism is 9:10:10 seconds. Then, when there is 0.5 seconds left from the current time to 9:10:10 seconds, the position of the winding and correcting mechanism can be adjusted according to the center point coordinates corresponding to the first position, so that the first position enters the winding and correcting mechanism at the middle position, and the time when the second position arrives at the winding and correcting mechanism is 9:10:11 seconds. Then, when there is 0.5 seconds left from the current time to 9:10:11 seconds, the position of the winding and correcting mechanism can be adjusted according to the center point coordinates corresponding to the second position, so that the second position enters the winding and correcting mechanism at the middle position, thereby allowing the first position and the second position of the cloth to be accurately aligned.

[0105] like Figure 4 As shown, the center coordinate corresponding to the first position is determined to be C 1n (X c1 , Y m1 ), the center coordinates corresponding to the second position are C 2n (X c2 , Y m2 ), and the calculated center coordinates C corresponding to the first position 1n (X c1 , Y m1 ), the center coordinate corresponding to the second position is C 2n (X c2 , Y m2 ), the two coordinate values ​​are the same, therefore, the cloth corresponding to the first position and the cloth corresponding to the second position are aligned. Then, after the first position reaches the winding and correcting mechanism, when the second position reaches the winding and correcting mechanism, there is no need to adjust the winding and correcting mechanism.

[0106] like Figure 5 As shown, the center coordinate corresponding to the first position is determined to be C 1n (X c1 , Y m1 ), the center coordinates corresponding to the second position are C 2n (X c2 , Y m2 ), and the calculated center coordinates C corresponding to the first position 1n (X c1 , Y m1 ), the center coordinate C corresponding to the second position 2n (X c2 , Y m2), the two coordinate values ​​are different. Therefore, the cloth corresponding to the first position and the cloth corresponding to the second position are not aligned.
