In this embodiment, the control method of the automatic stamping machine is used for the automatic stamping shown in Fig. 1 Take the machine as an example. As shown in Figure 4, the control method of this automatic stamping machine can include:

Step 410, when the image acquisition instruction is received, control the first camera device to photograph the document carried on the holder to obtain a first target image, and upload the first target image to the host computer.

The implementation of this step may be: receiving an image acquisition instruction sent by the host computer, and controlling the first camera device to photograph the document carried on the holder to obtain the first target image.

Wherein, the realization of the upper computer to obtain the image acquisition instruction can be: when the upper computer detects that the automatic stamping machine is connected to the upper computer, it displays the image acquisition button, and when it detects that the image acquisition button is triggered, it sends a message to the automatic stamping machine Send an image acquisition command.

It should be noted that before the host computer triggers the image capture button, the user places the document to be stamped on the holder 10 .

When the automatic stamping machine receives an image acquisition instruction, it controls the first camera device to take pictures of the documents carried on the holder to obtain a first target image, and uploads the first target image to the host computer.

Step 420: Receive a stamping instruction from the host computer that carries stamping position information, the stamping position information is the coordinate information of the selected area in the first target image or the selected position in the first target image.

After receiving the first target image, the upper computer displays the first icon image; acquires the area or position selected by the user in the first target image; acquires the coordinate information of the selected area or the selected position in the first target image .

Optionally, before the host computer generates the coordinate information, it can obtain the horizontal coordinate range of the holder and the longitudinal coordinate range of the holder; the horizontal coordinate range of the holder is determined as the horizontal coordinate range of the first icon image, and the The longitudinal coordinate range of the holder is determined as the longitudinal coordinate range of the first icon image.

If the user selects the stamping position on the host computer, step 420 may be implemented by receiving a stamping instruction from the host computer that carries stamping position information, and the stamping position information includes abscissa values and ordinate values.

If the user selects the stamping area on the host computer, the implementation of step 420 can be: receiving the stamping instruction sent by the host computer and carrying the stamping position information, the stamping position information includes the value range of the abscissa and the value of the ordinate scope.

Step 430, control the moving mechanism to drive the target stamp to stamp the document according to the stamp position information, so that the position of the target stamp stamped on the document is close to the position of the selected area or the selected position in the first target image or the same.

This step can be achieved in the following two ways:

First, if the seal position information includes the value of the abscissa and the value of the ordinate, then the control movement mechanism drives the target stamp to be stamped at the coordinate point formed by the value of the abscissa and the value of the ordinate on the holding member. chapter.

Second, if the seal position information includes the value range of the abscissa and the value range of the ordinate, then the control movement mechanism drives the target seal to form the value range of the abscissa and the value range of the ordinate on the holder. stamped in the area.

To sum up, in the method provided by the embodiment of the present invention, when an image acquisition instruction is received, the first camera device is controlled to photograph the file carried on the holder to obtain the first target image, and the first target image is uploaded To the host computer; receiving the stamp instruction sent by the host computer that carries the stamp position information, the stamp position information is the coordinate information of the selected area in the first target image or the selected position in the first target image; according to the Stamping position information controls the moving mechanism to drive the target stamp to stamp on the file, so that the position of the target stamp stamped on the document is close to or the same as the position of the selected area or the selected position in the first target image; solved In the related art, the intelligent stamping system is used to solve the problem of poor stamping accuracy; the effect of improving the poor precision of automatic stamping is achieved.

In one example, multiple stamps can be set in the safety box of the automatic stamping machine, and the stamping instruction received by the automatic stamping machine from the upper computer also includes the seal identification of the stamp selected by the user, then the automatic stamping machine performs the steps Before 430, the seal with the seal identification is determined as the target seal.

In an example, the stamping instruction also includes a stamp rotation angle. The upper computer can obtain the rotation angle of the stamp in the following ways:

The first one is to obtain the stamp rotation angle input by the user in the host computer. For example, display the input box for entering the stamp rotation angle, obtain the stamp rotation angle entered in the input box, and add the stamp rotation angle to the stamping command.

In the second type, the standard stamp image of the target stamp is displayed at the position selected by the user or in the area selected by the user on the first target image; the user can operate the standard stamp image to rotate the standard stamp image; the host computer obtains the standard stamp image The rotation angle of the printed image is added to the stamp instruction.

In one example, before step 430 is performed, the moving mechanism is controlled to drive the target stamp down to the ink pad area.

In one example, before step 430 is executed, the time when the target stamp was pressed down to the ink pad area last time is obtained; the number of times the target stamp is used in the time period from the acquisition time to the current time; according to the time interval between the time and the current time The length and the number of times of use determine whether the condition for increasing the ink pad is met; if the condition for increasing the ink pad is met, the moving mechanism is controlled to drive the target stamp down to the ink pad area.

Optionally, if it is detected that the time interval is longer than the preset time, it is determined that the ink pad increase condition is met, and the moving mechanism is controlled to drive the target stamp down to the ink pad area.

Optionally, if it is detected that the number of times of use is higher than the preset number of times, it is determined that the condition for increasing the ink pad is met, and the moving mechanism is controlled to drive the target stamp down to the ink pad area.

In one example, after step 430 is executed, the second camera is controlled to photograph the files carried on the holder to obtain a second target image, and the second icon image is uploaded to the host computer.

There are several ways to confirm whether the stamp affixed on the document carried on the holder is clear:

The first one, the host computer displays the second target image, confirmation button and re-stamp button; when the host computer detects that the confirmation button is triggered, it stops showing the second target image; when the host computer detects that the re-stamp button is triggered When triggered, firstly control the moving mechanism to drive the target stamp down to the ink pad area, and then execute step 430 again.

The second kind, after the host computer receives the second target image, extract the seal image of the target seal on the document from the second target image; the host computer calculates the similarity of the seal image and the standard seal image of the target seal; The automatic stamping machine sends the matching result with the similarity; the automatic stamping machine accepts the matching result; when the similarity in the matching result is lower than the preset threshold, the automatic stamping machine indicates that the seal of the document on the holder Unclear, at this time, control the moving mechanism to drive the target stamp down to the ink pad area, and then perform step 430 again.

Wherein, the implementation of extracting the stamp image of the target stamp on the document from the second target image can be: sequentially obtain the pixel value of each pixel in the standard stamp image; if the pixel value of the pixel indicates that the pixel If the color of the point is neither red nor a color close to red, update the pixel value of the pixel to 255.

Wherein, the preset range is set by the system developer, for example, the system developer can obtain the pink pixel value as the upper limit value of the preset range, and determine the red pixel value as the lower limit value of the preset range ; The standard seal image of the target seal is pre-stored in the host computer.

The third, after the host computer receives the second target image, it extracts the seal image of the target seal on the document from the second target image; the host computer calculates the similarity of the seal image and the standard seal image of the target seal; if If the similarity is lower than the preset threshold, first control the moving mechanism to drive the target stamp down to the ink pad area, and then execute step 430 again.

In an example, the user can control the automatic stamping machine on the host computer to enter the repeated stamping mode, and the automatic stamping machine that enters the repeated stamping mode stamps the same position on the holder, then the realization of step 430 can be : According to the position information of the stamp, control the moving mechanism to drive the target stamp to move to above the coordinate point corresponding to the stamp position information on the supporting part; after the control target stamp is pressed down on the document on the support part, the control target stamp is lifted ; According to the information detected by the sensor assembly, it is determined whether the file on the holder has been replaced; rise.

Optionally, before controlling the target stamp to press down on the file on the holder, it can also be determined whether the ink pad addition condition is met; if the ink pad addition condition is met, first control the moving mechanism to drive the target stamp down to the ink pad area; then Then control the moving mechanism to drive the target seal to move to the top of the coordinate point corresponding to the location information on the supporting member, and then control the target seal to press down to the file on the supporting member to complete a stamping operation.

Wherein, the sensor assembly may include a pressure sensor and/or an infrared sensor; for example, after the value detected by the pressure sensor is less than a predetermined value, and the value detected by the pressure sensor is higher than the predetermined value, it is considered that the file on the holder has been replaced . For another example, multiple infrared sensors are provided in the area on the holder for carrying documents. If the distances detected by the multiple infrared sensors are greater than the predetermined distance, the distances detected by the multiple infrared sensors are all smaller than the predetermined distance. Then it is considered that the file on the holder has been replaced.

In one example, when the automatic stamping machine detects that the box door is opened, it controls the second camera device to record until the box door is closed; and stores the video data recorded by the second camera device as a video file. This makes it easier to find the records of the person who stamped the seal later, and then identify whether there is a person who stamped beyond the authority.

Optionally, the image frame captured by the second camera is obtained; the face image is recognized from the image frame, and if the face image does not match the face image of the person legally stamped, the automatic stamp stamping machine is controlled to give an alarm. For example, control the buzzer alarm.

In one example, the electronic lock is connected with the automatic stamping machine; the user can enter a password in the electronic lock, and when the password entered by the user is correct, the electronic lock sends a message to the processor of the automatic stamping machine for notifying that the electronic lock has been activated. The first notification message of opening; the electronic lock sends the second notification message for notifying the electronic lock to the processor of the automatic stamping machine when it is closed; the processor of the automatic stamping machine controls the mechanical lock to be effective according to the first notification message , so that the user can use the mechanical key to open the box door; the processor of the automatic stamping machine controls the failure of the mechanical lock according to the second notification message, so that the user cannot open the box door with the mechanical key.

By setting an electronic lock, irrelevant personnel cannot perform stamping operations by destroying the mechanical lock. Only after the electronic lock recognizes the authority of the operator and the authentication is passed, the operator is allowed to use the mechanical key to open the mechanical lock and then perform the stamping operation. That is to say, the safety box has double insurance of electronic lock and mechanical lock, which greatly improves its safety performance.

In an example, when the automatic stamping machine detects that the safety box is mechanically damaged, the automatic stamping machine sends an alarm, thereby improving the safety performance of the automatic stamping machine.

In one example, the automatic stamping machine also includes a protection structure (not shown in the figure), which is electrically connected to the processor 40, and the protection structure is used to push against the holder 10 to eject when receiving an alarm command from the processor. Or close the box door 51. When the processor of the automatic stamping machine detects that the safety box encounters mechanical damage, it sends out an alarm command.
