As shown in fig. 1 to 3, the number of the at least one recognition pattern group P1 may be plural, so that the number of the at least one calibration object S1 may also be plural and equal to the number of the plurality of recognition pattern groups P1, and the control module may calculate the calibration parameters of each recognition pattern group P1 according to the calibration image of each calibration object S1.

Referring to fig. 4 and fig. 1 to 3 together, fig. 4 is a schematic top view of a conveying surface 1201 and a calibration object S1 of the automatic printing press 1000 with calibration function according to the embodiment of fig. 1. For example, the conveyor 1200 may first convey the calibration object S1, the calibration object S1 is placed on the recognition pattern group P1, the number of the position pattern P2 corresponding to the recognition pattern group P1 is 1, and the image recognition module 1300 may capture the position pattern P2, the recognition pattern group P1 and the calibration object S1 to obtain a position image, and then the printing module 1400 prints the calibration pattern C1 on the calibration object S1. Thereafter, the conveyor 1200 may reverse to transfer the calibration object S1 printed with the calibration pattern C1 back to the lower side of the image recognition module 1300 again, and the image recognition module 1300 captures a calibration image including the calibration pattern C1. The correction pattern C1 may include a plurality of geometric figures to form a geometric figure matrix, and the correction pattern C1 is illustrated as a dot matrix in fig. 4. In the absence of errors, the geometric matrix in the corrected image should be arranged normally, and if errors occur, the geometric matrix will be shifted or skewed, so as to analyze the errors of the recognition pattern group P1 with the number 1 of the position pattern P2. After all the sets of identification patterns P1 are processed in this manner, the error belonging to each identification pattern set P1 can be obtained. Since there are errors in the image recognition module 1300 during the shooting, and the errors at different positions of the conveyor 1200 are different during the transmission, the errors at different positions on the conveyor 1200 can be obtained by this method, and different correction parameters at different positions can be provided, so that the automatic printing machine 1000 with correction function of the present invention can improve the dynamic transmission error of the conveyor 1200 and the composite error formed by the image capturing error of the camera 1330 and its lens, thereby improving the accuracy of the whole printing. It should be noted that, since the conveyor 1200 only transmits one calibration object S1 at a time, only one calibration object S1 is illustrated in fig. 4, which is not intended to limit the present invention.

In other embodiments, the calibration pattern may include other patterns, and the calibration pattern may be selected by the control module according to the material and appearance texture of the calibration object. In other words, when the material of the calibration object is a material with large pores, it may not be suitable for printing dot matrix, and the same effect can be achieved by changing the material to lines, for example. It should be particularly noted that the material and the style of the calibration object may be the same as those of the actual object to be printed, which is helpful to improve the accuracy of the subsequent printing, and although the calibration object S1 in fig. 4 is exemplified by a middle sole cloth, in other embodiments, the object to be printed may be a shoe outsole, a shoe upper, or other material to be printed, and the invention is not limited thereto.

Referring to fig. 5 in conjunction with fig. 1 to 4, fig. 5 is a block flow diagram illustrating an automatic printing correction method 2000 according to embodiment 2 of the present invention. The automatic printing correction method 2000 includes a conveying step 201, a position image capturing step 202, a correction pattern printing step 203, a correction image capturing step 204, and a correction image analyzing step 205, and the details of the automatic printing correction method 2000 will be described below with reference to the automatic printing press 1000 having a correction function.

In the step 205 of analyzing the corrected image, the control module calculates the correction parameters of each recognition pattern group P1 according to the corrected image of each recognition pattern group S1. Further, each recognition pattern group P1 may correspond to a position pattern P2, and in the step 202 of capturing the position image, the control module recognizes the captured recognition pattern group P1 according to the captured position pattern P2 to correspond each calibration parameter to each recognition pattern group P1, so as to give a dedicated calibration parameter to each recognition pattern group P1 at different positions.

In addition, in the step 202 of capturing the position image, the control module may analyze the material of the at least one calibration object S1, and in the step 203 of printing the calibration pattern, the printing module 1400 prints the calibration pattern C1 corresponding to the material of the at least one calibration object S1, so as to select the appropriate calibration pattern C1 for calibration objects S1 of different materials.

Referring to fig. 6 and fig. 1 to 5 together, wherein fig. 6 is a flowchart illustrating steps of an automatic printing correction method 2000 according to the embodiment 2 of fig. 5. In step S01, the calibration process starts, and the process proceeds to step S02 to rotate the conveyor 1200 forward, and then step S03 is executed, wherein the image recognition module 1300 captures the position pattern P2 to execute step S04 to determine whether the current captured position is correct, wherein the position is the position where the recognition pattern group P1 is displayed, the position that has not been calibrated, or the position that is expected to be calibrated. If so, step S05 may be executed to determine whether the calibration object S1 in the image is located at the correct position, and if the calibration object S1 is located incorrectly, step S07 may be executed again to reset the calibration object S1, and if the position is correct, step S06 may be executed to select the calibration pattern C1 by the control module according to the material of the calibration object S1 and give it to the printing position, so step S08 may be entered, and the printing module 1400 may print the calibration object S1 according to the indicated calibration pattern C1 and printing position.

Then, step S09 may be executed to rotate the conveyor 1200 in reverse to return the calibration object S1 printed with the calibration pattern C1 to the position below the image recognition module 1300 again, step S10 may be executed to capture a calibration image of the calibration object S1 by the camera 1330 of the image recognition module 1300, the calibration image may be transmitted to the control module, step S11 may be executed to perform calibration analysis, after the deviation, skew or abnormality of the calibration pattern C1 is confirmed, calibration parameters may be generated, and step S12 may be executed to assign the calibration parameters to the recognition pattern group P1 at the position and store the calibration parameters.

Then, step S13 may be executed again to confirm whether the next position is corrected, and steps S02 to S13 are repeated until all the positions are corrected, and step S14 is executed to end the correction.

After completing the automatic printing correction method 2000, the conveyor 1200 may formally convey the material to be printed, the image recognition module 1300 may capture the position image of the material to be printed and the recognition pattern group P1 where the position is located, and the control module may also analyze the position image and provide the printing position, and the printing module 1400 may print the printing pattern on the material to be printed according to the printing position and the stored correction parameters. Thus, the printing module 1400 uses the calibration parameters, thereby improving the printing accuracy.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention.
