It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

Referring to fig. 1, the application environment includes a computer device 10 and a 3D printer 20. Wherein the computer device 10 may generate an original image of each slice layer of the 3D model to be printed and transmit the original image of each slice layer to the 3D printer 20. The 3D printer 20 may print out the 3D model based on the original image of each slice layer.
In particular implementations, the computer device 10 may be, but is not limited to, various personal computers, notebook computers, and the like. The 3D printer 20 may be a fused deposition FDM printer, a digital light processing DLP printer, or a stereolithography SLA printer. The computer device 10 may communicate with the 3D printer 20 by wired or wireless means. The application is not limited in this regard.
The continuous printing method of the 3D printer provided by the embodiment of the application can be applied to the application environment shown in fig. 1, and an execution subject of the method can be the computer equipment or the 3D printer shown in fig. 1. Of course, the application environment to which the method is applicable may include only a 3D printer, and no computer device, and the execution subject of the method is the 3D printer, and all the data processing procedures related to the present application are executed in the printer. The 3D printer may be a fused deposition FDM printer, a digital light processing DLP printer, or a stereolithography SLA printer. The application is not limited in this regard.
At present, when a 3D printer has a print interruption in the middle of printing, the printed part is often discarded, and printing is restarted, so that material waste is caused.
Based on the method, the continuous printing method of the 3D printer can finish continuous printing operation under the condition of printing interruption, and waste of printing materials is reduced. Meanwhile, when continuous printing is performed based on the finished printing part, the position offset of the continuous printing part and the printed part can be avoided to a certain extent, and the accuracy of continuous printing is ensured. Fig. 2 is a flow chart of a continuous printing method of a 3D printer according to an embodiment of the present application, which is illustrated by taking a computer device in fig. 1 as an example, and includes the following steps:
step 201, acquiring an actual image of a target slice layer of a target model and an original image of the target slice layer;
in order to finish continuous printing of the target model, the embodiment of the application can firstly determine the original image of any slice layer of which the target model is printed currently, so as to determine the position of the printed part of the target model currently based on the original image, thereby enabling the 3D printer to finish accurate continuous printing of the target model.
The target model is a whole 3D model which needs to be printed; the target slice layer is any slice layer of which the target model finishes printing currently, namely any slice layer of all slice layers which finish printing before the printing is interrupted. The slice layer is selected according to the actual situation, and the final purpose is to determine the slice layer with clear outline as the target slice layer. For example, if the shape of the portion of the target model that has been currently printed is small, the slice layer near the print platform may be determined to be the target slice layer. If the shape of the currently completed print portion of the target model is large up and small down, the uppermost slice layer of the currently completed print portion of the target model may be determined as the target slice layer. The method comprises the steps of carrying out a first treatment on the surface of the The actual image is a cut-plane image of the currently completed printed portion, and may be, for example, an image of the last cut-plane layer of the currently completed printing. The original image is a slice image generated by the target slice layer.
In a specific implementation, image acquisition can be performed on the currently finished printing part, and an actual image of the target slice layer can be acquired. The computer device may generate print information of the object model, and the computer device may acquire an original image of the object slice layer from the print information of the object model in step 201.
Step 202, determining the offset between the actual image and the original image;
the computer equipment of the embodiment of the application can also determine the position deviation between the actual image and the original image of the target slice layer so as to ensure the accuracy of continuous playing of the target model based on the position deviation between the actual image and the original image. Wherein the positional deviation between the actual image and the original image of the target slice layer may be referred to as an offset.
In a specific implementation, the computer device may compare the actual image with the original image, obtain a positional deviation of the actual image and the original image with respect to the same reference plane, and determine the positional deviation as an offset between the two.
The reference plane may be, for example, a horizontal plane on which the printing platform is located. The actual image and the original image can comprise image elements of the model slice and image elements of the printing platform, so that the computer equipment can compare the actual image with the original image by taking the position of the printing platform as a reference quantity, and the offset is obtained. In a possible implementation, a position deviation (denoted as a first position deviation) between an image element of the model slice in the actual image and an image element of the print platform is calculated, a position deviation (denoted as a second position deviation) between an image element of the model slice in the original image and an image element of the print platform is calculated, and an offset between the actual image and the original image is determined based on the first position deviation and the second position deviation.
And 203, adjusting the data of the original images of all the unprinted slice layers corresponding to the target model according to the offset, and completing continuous printing of the target model based on the adjusted data of the original images of all the unprinted slice layers.
In order to ensure the accuracy of continuous printing of the target model, the embodiment of the application firstly adjusts the data of the original images of all unprinted slice layers to the position matched with the actual image so as to finish the accurate continuous printing of the target model.
The data of the original image is print data before the print interruption, for example, may be coordinates of each point on each slice layer before the print interruption.
In a specific implementation, the computer device adjusts the data of the original images of all the unprinted slice layers according to the obtained offset between the actual image and the original image of the target slice layer, so that the positions of the original images of all the unprinted slice layers are matched with the positions of the actual images. And then, based on the adjusted data of the original images of all the unprinted slice layers, instructing the printer to execute continuous printing operation of the target model.
According to the continuous printing method of the 3D printer, the actual image of the target slice layer of the target model and the original image of the target slice layer can be obtained, the position offset between the two slice images is determined based on the two slice images, and then the data of the original images of all unprinted slice layers are adjusted based on the position offset, so that the 3D printer can continuously print the target model under the condition of printing interruption, discarding of a printed part is avoided, material waste is reduced, and meanwhile, the position offset of the continuous printing part and the printed part can be avoided to a certain extent when continuous printing of the printed part is completed, and the accuracy of continuous printing is ensured.
The foregoing embodiments describe a solution for acquiring an actual image of a target slice layer of a target model. In another embodiment of the application, a top view of the target model may be acquired, thereby acquiring an actual image of a target slice layer of the target model. For example, "acquiring an actual image of a target slice layer of a target model" referred to above specifically includes:
image acquisition is carried out on the surface of the target model, which is away from the direction of the printing table, so as to obtain an actual image of the target slice layer; the target slice layer is the last slice layer of the target model that is currently printed.
In a specific implementation, as shown in fig. 3, the acquisition device photographs the surface of the target model facing away from the direction of the printing platform, so as to acquire an actual image of a target slice layer of the target model, and sends the actual image to the computer device. The acquisition device can communicate with the computer device in a wired or wireless mode. The acquisition device can be a camera, a mobile phone or other devices capable of acquiring images.
In one possible implementation, the acquisition device may be integrated on the 3D printer as part of the 3D printer. When the image acquisition is needed, the computer equipment instructs the acquisition equipment to move to a designated position, the target slice layer is photographed, an actual image of the target slice layer is obtained, and the actual image is sent to the computer equipment and is processed by the computer equipment. For example, the computer device instructs the acquisition device to move to a position right above the target model, and photographs the target slice layer of the target model from top to bottom, so as to obtain a top view of the target slice layer, namely, an actual image of the target slice layer.
In one possible implementation manner, the acquisition device may be an independent acquisition device, the acquisition device is manually operated to photograph the target slice layer from top to bottom, obtain an actual image of the target slice layer, and send the obtained actual image to the computer device for processing by the computer device.

Therefore, the acquisition equipment acquires the actual image of the target slice layer by shooting the target slice layer from top to bottom, namely the acquisition equipment acquires the top view of the target slice layer, so that the acquired actual image is closer to the actual shape of the target slice layer on the horizontal plane.
The foregoing embodiments describe a solution for acquiring an original image of a target slice layer of a target model. In another embodiment of the present application, the original image of the target slice layer may be found from the original image set of the target model based on the number of layers of the target slice layer. For example, the foregoing relates to "acquiring an original image", specifically including the steps as shown in fig. 4:
Step 401, determining the current printing height of the target model, and determining the layer number corresponding to the height;
in order to ensure accuracy of continuous playing, the embodiment of the application needs to know the position of the continuous playing, namely the specific layer number of the continuous playing. Therefore, the position of the target slice layer can be determined first, and the continuous playing position is the upper layer of the target slice layer.
In the specific implementation, a calibration object with the height L can be placed on a printing platform, and then the target model and the calibration object are photographed to obtain a calibration image. And (3) performing image processing on the calibration image by a computer to obtain the height H of the target model which is printed currently. Then, the computer device may acquire the height H0 of one slice layer of the target model from the original print data, and determine the number of layers corresponding to the height at which the target model has finished printing according to the height H at which the target model has finished printing and the height H0 of one slice layer. The calibration image is an image containing a target model and a calibration object; the calibration object is an object with a known height; the original print data is data indicating the 3D printer to print the target model before the print interruption. The calibration object may be a highly known box, ruler or other object, or may be a Z-axis, which is not limited in the present application.
In one possible implementation, the computer device may instruct the acquisition device to move to the right in front of the target model (photographing from front to back) or to the right (photographing from right to left) or to other locations where the entire target model and calibration object may be photographed, then photograph the target model and calibration object to obtain a calibration image, and send the calibration image to the computer device. The computer equipment carries out image recognition on the calibration image to obtain the pixel height H1 of the current finished printing part of the target model and the pixel height L1 of the calibration object, and the pixel number of the unit height (1 mm) is shown in the following formula (1):
the height H of the currently completed print portion of the target model is shown in the following formula (2):
the number of layers X corresponding to the height H of the currently completed print portion of the target model is shown in the following formula (3):
in one possible implementation manner, the acquisition device can be manually operated to photograph the target model from front to back or from right to left to obtain a calibration image, the calibration image is sent to the computer device, the computer device processes the calibration image to obtain the height H of the target model, which is printed, and the number of layers corresponding to the height of the target model, which is printed, is determined according to the height H of the target model, which is printed currently, and the height H0 of one slice layer.
Step 402, acquiring an original image of a target slice layer from an original image set of a target model according to the layer number; the original image set includes the original images of all slice layers of the object model.
In a specific implementation, the computer equipment determines an original image at a corresponding position in the original image set according to the acquired number of layers of the target slice layer, namely the original image of the target slice layer.
The original image set comprises original images of all slice layers of the target model, namely the slice images of all slice layers before the printing is interrupted.
The embodiment of the application provides a method for acquiring an original image of a target slice layer, in particular to a method for acquiring a calibration image by photographing a target model and a calibration object through acquisition equipment and sending the calibration image to computer equipment. And the computer equipment performs image processing on the calibration image to obtain the current printing completed height of the target model, and obtains the number of layers of the target slice layer of the target model according to the height and the height of one slice layer of the target model. And finally, inquiring the original image at the corresponding position in the original image set according to the layer number of the target slice layer, namely the original image of the target slice layer. According to the embodiment of the application, the number of layers of the target slice layer and the original image corresponding to the target slice layer are automatically acquired by adopting the image identification method, so that the situation of manually designating the number of layers of the target slice layer is avoided, the accuracy of the acquired number of layers of the target slice layer is improved, and the accuracy of the acquired original image of the target slice layer is further improved.
The foregoing embodiments describe a scheme for finding an original image of a target slice layer from an original image set of a target model based on the number of layers of the target slice layer. In another embodiment of the present application, the corresponding original image of the target slice layer in the original image set of the target model may be determined as the original image of the target slice layer. For example, "the original image of the target slice layer is acquired from the original image set of the target model according to the number of layers" referred to above.
In a specific implementation, the computer device may directly obtain the original image of the target slice layer from the original image set according to the number of layers of the target slice layer. Specifically, the computer device queries an original image corresponding to the same layer number position from the original image set according to the obtained layer number of the target slice layer, and determines the original image as the original image of the target slice layer.
The embodiment of the application provides a method for determining an original image of a target slice layer, and particularly, computer equipment can determine the original image with the same layer number as the target slice layer in an original image set as the original image of the target slice layer. The method for determining the original image of the target slice layer can directly determine the original image with the same layer number as the target slice layer as the original image of the target slice layer, so that the original image of the target slice layer can be accurately obtained.
The foregoing embodiments describe a scheme for finding an original image of a target slice layer from an original image set of a target model based on the number of layers of the target slice layer. In another embodiment of the present application, the original image that most matches the actual image may be determined as the original image of the target slice layer from among the sets of original images corresponding to the plurality of slice layers adjacent to the target slice layer. For example, "acquiring an original image of a target slice layer from an original image set of a target model according to the number of layers" referred to above specifically includes the steps as shown in fig. 5:
step 501, determining a plurality of slice layers adjacent to the layer number;
in order to improve the accuracy of the acquired original image of the target slice layer, the embodiment of the application can perform query processing on a plurality of slice layers.
In a specific implementation, the computer device may obtain a preset number of slice layers adjacent to the target slice layer. The number of preset layers can be 30, 40 or 50.
In one possible implementation, since the image recognition height is more than 2 and the FDM photo-cured layer is 0.1mm in height, when the preset number of layers is 40, the 40-layer original image may completely include the original image of the target slice layer. Thus, as shown in fig. 6, the computer device may determine a total of 40 slice layers as a plurality of slice layers adjacent to the target slice layer, 20 slice layers above the target slice layer and 20 slice layers below the target slice layer.
Step 502, obtaining a plurality of original images corresponding to a plurality of slice layers from an original image set;
in a possible implementation manner, 20 layers of original images above the original image with the same layer number as the target slicing layer and 20 layers of original images below the original image with the same layer number as the target slicing layer in the original image set may be obtained, and the total number of the original images is 40, where the 40 original images are the original images corresponding to multiple slicing layers.
And 503, determining an original image with the highest matching degree with the actual image in the plurality of original images as an original image of the target slice layer.
In a specific implementation, the computer equipment respectively matches the 40 original images with the actual images of the target slice layer to obtain 40 matching degrees, and the original image with the highest matching degree is determined to be the original image of the target slice layer.
In a possible implementation manner, the profiles of the target slice layers of the 40 original images and the actual image may be obtained, the profiles corresponding to the 40 original images are respectively matched with the profiles corresponding to the actual image, 40 profile matching degrees are obtained, and the original image with the highest profile matching degree is determined as the original image of the target slice layer.
In a possible implementation manner, if there are multiple original images with highest profile matching degree, determining an original image with the closest layer number to the target slice layer as the original image of the target slice layer in the multiple original images with highest profile matching degree.
The embodiment of the application provides a method for determining an original image of a target slice layer, and specifically, computer equipment can respectively match original images adjacent to the target slice layer in an original image set with actual images of the target slice layer by a preset layer number, and determine the original image with highest matching degree as the original image of the target slice layer. Therefore, after the number of layers of the target slice layer is obtained, the method and the device of the application perform query comparison on the plurality of original images adjacent to the number of layers one by one, and determine the queried original image which is most matched with the actual image as the original image of the target slice layer, thereby further improving the accuracy of the obtained original image.
The foregoing embodiments describe a scheme for determining the offset between the actual image and the original image of the target slice layer. In another embodiment of the present application, the offset amounts of the actual image and the original image may be determined based on a rotation matrix, a horizontal offset, and a vertical offset between the contours of the actual image and the original image. For example, the foregoing relates to "determining the offset between the actual image and the original image", specifically including the steps as shown in fig. 7:
701, performing contour recognition on an actual image to obtain a first contour, and performing contour recognition on an original image to obtain a second contour;
in order to ensure the accuracy of continuous printing of the 3D printer, the offset of the target model is determined after the printing is interrupted, so that the outline of the actual image and the outline of the original image of one slice layer can be acquired first, and the offset between the outline of the actual image and the outline of the original image of the slice layer is the offset of the target model.
The offset may include an offset of a rotation angle of the target model, an offset in a horizontal direction, and an offset in a vertical direction, among others.
In specific implementation, the computer equipment performs contour recognition on the obtained actual image of the target slice layer, and obtains the contour of the actual image, namely a first contour; and then the computer equipment carries out contour recognition on the determined original image of the target slice layer, and the contour of the original image is obtained, namely the second contour.
Step 702, determining a rotation matrix between the first contour and the second contour, and performing rotation processing on the second contour based on the rotation matrix;
in a specific implementation, the computer device performs image recognition processing on the obtained first contour and the obtained second contour, and determines a rotation matrix degree between the first contour and the second contour, wherein the rotation angle is the offset of the target model in angle.
Since the first contour and the second contour need to be on parallel horizontal lines when determining the offset of the target model in the horizontal and vertical directions, as shown in fig. 8, the rotation processing may be performed on the second contour corresponding to the original image based on the rotation angle θ between the two contours determined above, so that the rotated second contour and the first contour are on parallel horizontal lines.
