[0073] In order to make the above objectives, characteristics and advantages of the present application more apparent, comprehensible and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0074] At present, when the cloth is rectified, the rectification sensor is adopted, but the alignment of this way can only be roughly aligned and cannot be accurately aligned. The present application provides a cloth rectification method to solve the above technical problems, the core idea of which is to first obtain the cloth image shot by the camera, and then determine the center point coordinates on the cloth corresponding to the first position according to the cloth image, and then determine the center point coordinates on the cloth corresponding to the second position, 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 reach the winding rectification mechanism, and finally adjust the position of the winding rectification mechanism according to the time when the first position and the second position reach the winding rectification mechanism, the center point coordinates corresponding to the first position, and the center point coordinates corresponding to the second position, so as to determine the center point coordinates corresponding to the first position and the center point coordinates corresponding to the second position according to the camera shooting, and adjust the position of the winding rectification mechanism, and then adjust the position of the cloth entering the winding rectification mechanism, so that the first position and the second position of the cloth can be accurately aligned.

[0075] Referring to Figure 1 , a step flow chart of a cloth rectification method provided by an embodiment of the present application is shown, the method is applied to a controller; the controller is connected with a winding rectification mechanism of a camera respectively, and the method can specifically include the following steps:

[0076] Step 101, obtaining the cloth image shot by the camera, and determining the center point coordinates on the cloth corresponding to the first position according to the cloth image.

[0077] In the embodiment of the present application, as Figure 2 shown, a structural block diagram of a rectification device provided by an embodiment of the present application is shown, a camera is arranged above the E point, the K point is a winding rectification mechanism structure, and an encoder is arranged above the G point. The cloth can pass through the E, F, G, H, I and J points in turn, and then reach the winding rectification mechanism at the K point. The encoder is used for controlling the camera to take pictures.

[0078] In the embodiment of the present application, the camera can shoot the E point in real time, the controller can obtain the cloth image shot by the camera, and then determine the center point coordinates on the cloth corresponding to the first position according to the cloth image.

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

[0080] As shown in Figure 3 , a schematic diagram of camera shooting is shown. The cloth in the picture shot by the camera is Figure 2 the cloth at the position of E point in the middle. Because the camera is fixed, a coordinate system can be set in advance for the camera shooting configuration. Then, after the camera shoots the picture of the cloth, the coordinates of the two sides of the cloth can be determined.

[0081] In an embodiment, according to the cloth image, the center point coordinates corresponding to the first position on the cloth can 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 the two side coordinates corresponding to the first position on the cloth; and determining the center point coordinates corresponding to the first position on the cloth according to the first coordinate and the second coordinate corresponding to the first position on the cloth.

[0082] Specifically, taking Figure 3 for example, the first coordinate corresponding to the first position on the cloth in the cloth image is (X a1 , Y m1 ), and the second coordinate is (X b1 , Y m1 ). The first coordinate and the second coordinate are the two side coordinates corresponding to the first position on the cloth. Then, according to the first coordinate (X a1 , Y m1 ) and the second coordinate (X b1 , Y m1 ), the center point coordinates corresponding to the first position on the cloth are calculated as (X c1 , Y m1 ).

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

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

[0085] In one embodiment, determining the coordinates of the center point on the fabric corresponding to the second position may include: determining whether there is damage at the second position on the fabric; when there is no damage at the second position on the fabric, obtaining the third and fourth coordinates on the fabric corresponding to the second position; the third and fourth coordinates are the coordinates of the two sides on the fabric corresponding to the second position, respectively; determining the coordinates of the center point on the fabric corresponding to the second position based on the third and fourth coordinates on the fabric; and when there is damage at the second position on the fabric, determining the coordinates of the center point of the second position based on the coordinates of the center point on the fabric corresponding to the first position.

[0086] Specifically, when determining the center point coordinates corresponding to the second position on the fabric, the present invention first determines whether there is any damage to the second position on the fabric. That is, it first determines whether there is any damage to the fabric. If there is no damage to the second position on the fabric, the center point coordinates corresponding to the second position can be determined in the same way as the center point coordinates corresponding to the first position.

[0087] For example: the third coordinate on the fabric 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 of the two sides of the fabric corresponding to the second position. Then, based on the third coordinate (X... a2 Y m2 ), and the fourth coordinate (X) b2 Y m2 The coordinates of the center point on the fabric corresponding to the second position are calculated as (X...). c2 Y m2 ).

[0088] For example, such as Figure 4 The diagram shown illustrates the position of a piece of fabric according to an embodiment of the present invention. Figure 4 The first coordinate corresponding to the first position in the middle is A. 1n (X a1 Y m1 The second coordinate is B. 1n (X b1 Y m1 Therefore, 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 Therefore, 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 If the two positions are the same, then the fabric corresponding to the second position is centered and aligned with the fabric corresponding to the first position.

[0089] For example, such as Figure 5 The diagram illustrates another fabric position provided by an embodiment of the present invention. Figure 5 The first coordinate corresponding to the first position in the middle is A. 1n (X a1 Y m1 The second coordinate is B. 1n (X b1 Y m1 Therefore, 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 Therefore, 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 If they are not the same, then the fabric corresponding to the second position is not centered with the fabric corresponding to the first position.

[0090] When the second position on the cloth has a damage phenomenon, the center point coordinate of the second position can be determined according to the center point coordinate of the first position on the cloth.

[0091] In an embodiment, determining whether the cloth has a damage phenomenon can include: determining a position where the cloth has a width change; determining that the cloth has a damage phenomenon when the width change corresponding to the position where the cloth has the width change is within a preset range; and determining that the cloth does not have a damage phenomenon when the width change corresponding to the position where the cloth has the width change is not within the preset range.

[0092] Specifically, when the cloth has a width change, it indicates that the cloth has a change, at this time, there are two possibilities, the first is that there is new cloth, and the position of the new cloth has changed from the position of the previous cloth, and the second is that the edge of the cloth has a damage phenomenon, so the width of the cloth changes. However, the damage range of the cloth is generally small, when the width change corresponding to the position where the cloth has the width change is within a preset range, it can be determined that the cloth has a damage phenomenon, and when the width change corresponding to the position where the cloth has the width change is not within the preset range, it can be determined that the cloth does not have a damage phenomenon.

[0093] For example, Figure 4 and Figure 5 The width of the cloth changes in both Figure 4 and Figure 5 However, new cloth appears in Figure 6 and Figure 5 , at this time, the width change corresponding to the position where the cloth has the width change is certainly not within the preset range, so it can be determined that the cloth does not have a damage phenomenon, but is replaced by new cloth. For another example, as shown in Figure 6 , another schematic diagram of a cloth position provided by an embodiment of the present application is shown. Figure 6 The width of the cloth changes in both Figure 4 and Figure 5 , but the width change changes back to the original width after a short distance, so the width change corresponding to the position where the cloth has the width change is within the preset range, at this time, it can be determined that the cloth has a damage phenomenon.

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

[0095] Specifically, as shown in Figure 6 , another schematic diagram of a cloth position provided by an embodiment of the present application is shown. Figure 6The first coordinate corresponding to the first position is A 1n (X a1 , Y m1 ), and the second coordinate is B 1n (X b1 , Y m1 ). Then the center coordinate C 1n (X c1 , Y m1 ) corresponding to the first position can be calculated. Figure 6 The second position has a damage phenomenon. At this time, the third coordinate corresponding to the second position is A 2n (X a2 , Y m2 ), and the fourth coordinate is B 2n (X b2 , Y m2 ). Then the center coordinate C 2n (X c2 , Y m2 ) corresponding to the second position can be calculated. However, because the second position has a damage phenomenon, the center coordinate C 2n (X c2 , Y m2 ) corresponding to the second position calculated is obviously not correct. Because the two side coordinates corresponding to the positions after the second position are the same as the two side coordinates corresponding to the first position, the center coordinate C 1n (X c1 , Y m1 ) corresponding to the first position can be 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 determine the time when the first position and the second position reach the winding and correcting mechanism.

[0097] In the embodiment of the present application, after the center coordinate corresponding to the second position on the cloth is determined, the time when the first position and the second position reach the winding and correcting mechanism can be respectively determined.

[0098] In an embodiment, respectively determining the time when the first position and the second position reach the winding and correcting mechanism comprises: acquiring the distance between the first position and the winding and correcting mechanism; acquiring the shooting time corresponding to the first position and the second position respectively; acquiring the running speed of the winding and correcting mechanism; and respectively determining the time when the first position and the second position reach 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.

[0099] Specifically, the controller can first acquire the distance between the first position and the winding and rectifying mechanism when the photo is taken, which is the distance from E point to K point. Figure 2 The sum of the distances from E point to F point, F point to G point, G point to H point, H point to I point, I point to J point and J point to K point, that is, the distance of the cloth running to the winding and rectifying mechanism when the corresponding area is photographed by the camera, and then the corresponding photographing time of the first position and the second position is acquired, for example, the photographing time corresponding to the first position is 10:10, and the photographing time corresponding to the second position is 10:11.

[0100] Then, the running speed of the winding mechanism is acquired, and then the running time of the cloth from E point to K point can be determined according to the distance between the first position and the winding and rectifying mechanism and the running speed of the winding mechanism, for example, the running time from E point to K point is 5 seconds, and then the time when the first position reaches the winding and rectifying mechanism is determined as 10:15, and the time when the second position reaches the winding and rectifying mechanism is determined as 10:16.

[0101] In step 104, the position of the winding and rectifying mechanism is adjusted according to the time when the first position and the second position reach the winding and rectifying mechanism, the center point coordinate corresponding to the first position, and the center point coordinate corresponding to the second position.

[0102] In the embodiment of the present application, after the time when the first position and the second position reach the winding and rectifying mechanism is determined, the position of the winding and rectifying mechanism can be adjusted according to the time when the first position and the second position reach the winding and rectifying mechanism, the center point coordinate corresponding to the first position, and the center point coordinate corresponding to the second position, so that the first position and the second position of the cloth can be accurately aligned.

[0103] In an embodiment, adjusting the position of the winding and rectifying mechanism according to the time when the first position and the second position reach the winding and rectifying mechanism, the center point coordinate corresponding to the first position, and the center point coordinate corresponding to the second position includes: when the current time is separated from the time when the first position reaches the winding and rectifying mechanism by a preset time, adjusting the position of the winding and rectifying mechanism according to the center point coordinate corresponding to the first position; and when the current time is separated from the time when the second position reaches the winding and rectifying mechanism by a preset time, adjusting the position of the winding and rectifying mechanism according to the center point coordinate corresponding to the second position.

[0104] Specifically, the preset time is 0.5 seconds, the first position reaches the winding deviation correction mechanism at 9:10:10, and thus when the current time is 0.5 seconds away from 9:10:10, the position of the winding deviation correction mechanism can be adjusted according to the center point coordinates corresponding to the first position, so that the first position enters the winding deviation correction mechanism at the middle position when entering the winding deviation correction mechanism. The second position reaches the winding deviation correction mechanism at 9:10:11, and thus when the current time is 0.5 seconds away from 9:10:11, the position of the winding deviation correction mechanism can be adjusted according to the center point coordinates corresponding to the second position, so that the second position enters the winding deviation correction mechanism at the middle position when entering the winding deviation correction mechanism, so that the first position and the second position of the cloth can be accurately aligned.

[0105] As shown in Figure 4 , the center coordinates corresponding to the first position are determined as C 1n (X c1 , Y m1 ), the center coordinates corresponding to the second position are C 2n (X c2 , Y m2 ), the calculated center coordinates corresponding to the first position are C 1n (X c1 , Y m1 ), and the center coordinates corresponding to the second position are C 2n (X c2 , Y m2 ), and the two coordinate values are the same, so the cloth corresponding to the first position and the cloth corresponding to the second position are in an aligned state, and thus when the second position reaches the winding deviation correction mechanism after the first position reaches the winding deviation correction mechanism, the winding deviation correction mechanism does not need to be adjusted.

[0106] As shown in Figure 5 , the center coordinates corresponding to the first position are determined as C 1n (X c1 , Y m1 ), the center coordinates corresponding to the second position are C 2n (X c2 , Y m2 ), the calculated center coordinates corresponding to the first position are C 1n (X c1 , Y m1 ), and the center coordinates corresponding to the second position are C 2n (X c2 , Y m2Since the two coordinate values ​​are different, the fabric at the first position and the fabric at the second position are not aligned. Therefore, after the first position reaches the winding and straightening mechanism but before the second position reaches the winding and straightening mechanism, the fabric needs to be aligned according to the center coordinate C corresponding to the second position. 2n (X c2 Y m2 Adjustments were made to the winding and correction mechanism.

[0107] like Figure 6 As shown, the fabric at the second position is damaged, and the center coordinate of the first position is determined to be C. 1n (X c1 Y m1 Based on the center coordinates corresponding to the first position, and considering that the coordinates corresponding to the two sides of the second position are the same as those corresponding to the two sides of the first position, we can determine that the center coordinates corresponding to the second position are the same as the center coordinates C of the first position. 1n (X c1 Y m1 Therefore, the fabric corresponding to the first position and the fabric corresponding to the second position are actually aligned. So, after the first position reaches the winding and straightening mechanism, when the second position reaches the winding and straightening mechanism, there is no need to adjust the winding and straightening mechanism.
