[0024] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0026] After research, the applicant found that in a 3D printing scenario, users may want to retrieve the 3D printing data of a model. For example, during the 3D printing process, printing anomalies may occur, such as faults, falling boards, and other problems. Faults refer to the displacement of the exposure positions of different layers due to residues or loose deformation of the structure during the 3D printing process, resulting in obvious cross-sectional offset marks. Falling boards refer to the fact that the printing platform is not firmly bonded to the material, resulting in the failure of the printing platform to pull up the 3D model during the 3D printing process, and the 3D model is attached to the bottom of the material box. At this time, it is necessary to troubleshoot the problem based on the 3D printing data corresponding to the anomaly, and then re-perform 3D printing. Since there is currently no simple and convenient way to retrieve 3D printing data, when users want to retrieve the 3D printing data of a model, they can only search manually, which is time-consuming, labor-intensive, and very inconvenient.

[0027] Figure 1 1 is a flowchart of a method for processing 3D printing data provided by an embodiment of the present disclosure, and the method can be executed by an electronic device. The electronic device can be exemplarily understood as a device such as a 3D printer, a mobile phone, a tablet computer, a laptop computer, a desktop computer, a smart TV, or a server. Figure 1 As shown, the method provided in this embodiment includes the following steps:

[0028] S110: Obtain search information.

[0029] In the disclosed embodiment, when a user wants to retrieve 3D printing data of a 3D model (i.e., a retrieval model), the user may input retrieval information into the electronic device. After acquiring the retrieval information, the electronic device may perform a retrieval based on the retrieval information. The retrieval model may be, for example, a model with printing abnormalities, etc., but is not limited thereto.

[0030] Specifically, the representation form of the three-dimensional model may include point cloud, Mesh, etc., but is not limited thereto.

[0031] Specifically, the search information is information that the electronic device relies on to search in the three-dimensional printing database. The search information may be in the form of text, image, or voice, but is not limited thereto.

[0032] In some embodiments, S110 may include: obtaining a search term, wherein the search term includes node information of each process node in the process of performing three-dimensional printing on the three-dimensional model. It should be noted that the number of the search terms is greater than or equal to one.

[0033] Specifically, the process nodes of 3D printing may include process nodes such as typesetting, slicing, sending, and printing, but are not limited thereto.

[0034] At the layout process node, the 3D models to be 3D printed together can be layouted, that is, the sorting order and relative position relationship of the 3D models to be 3D printed together can be set, and then the model list layout data can be obtained. The model list layout data can include the model list and layout views of the 3D models to be 3D printed together, and the layout views include views obtained by image acquisition after being arranged in the corresponding sorting order and relative position relationship, such as a top view, a left view, a right view, a front view, and / or a rear view, but are not limited thereto.

[0035] The node information of the layout process node may include: layout time, the number of 3D models involved in layout, and / or attribute information of the 3D models involved in layout, etc., but is not limited thereto. The attribute information of the 3D model may include: model name, model number, model model, model size, etc., but is not limited thereto.

[0036] In the slicing process node, the 3D model to be 3D printed can be sliced ​​to obtain slice data, and the slice data is saved in a slice file.

[0037] The node information of the slicing process node may include: slicing time, number of slices, number of 3D models involved in slicing, and / or attribute information of the slicing file, etc., but is not limited thereto. The attribute information of the slicing file may include: slicing file name, slicing file size, etc., but is not limited thereto.

[0038] In the sending process node, the slice data of the 3D model to be printed can be sent to the printing device.

[0039] The node information of the sending process node may include: sending time, sending method, etc., but is not limited thereto. The sending method may include Bluetooth, WIFI, network cable, etc., but is not limited thereto.

[0040] At the printing process node, the printing device can perform three-dimensional printing based on the slice data, thereby printing the three-dimensional model to be printed on the printing platform.

[0041] The node information of the printing process node may include, but is not limited to, printing time and / or device information of the printing device, etc. The device information of the printing device may include, but is not limited to, device name, device model, device manufacturer name, device placement location, etc.

[0042] In some other embodiments, S110 may include: acquiring a retrieval image, wherein the retrieval image at least includes an image region corresponding to the retrieval model.

[0043] Specifically, the retrieval model is a model that the user wants to retrieve, or in other words, a model whose three-dimensional printing data the user wants to obtain.

[0044] Specifically, the search image may be an image acquired by capturing the search model, or may be an image acquired by capturing the search model and other three-dimensional models printed together with the search model, without limitation. The image acquisition may be performed from a frontal view, a left front view, a right front view, a left rear view, and / or a right rear view, but is not limited thereto.

[0045] S120 , searching the 3D printing database for target 3D printing data that matches the search information.

[0046] Specifically, the target 3D printing data is the 3D printing data that matches the search information. The 3D printing data may include: model list layout data, slice data, and node information of each process node, but is not limited thereto. For example, one 3D printing corresponds to one piece of 3D printing data, and one piece of 3D printing data includes: the corresponding 3D printing model list layout data, slice file, and node information of each process node, etc.

[0047] In some embodiments, the search information includes a search term. Accordingly, S120 may include: searching a 3D printing database for target 3D printing data that matches the search term.

[0048] Specifically, the target three-dimensional printing data includes node information of each process node, and the search term matches the node information in the target three-dimensional printing data.

[0049] It is understandable that the user can input one search term into the electronic device, or can input multiple search terms to perform a comprehensive search of multiple search terms (for example, a comprehensive search of model name, slice file name, slice time, printing device name, etc.). In this way, after the electronic device obtains the search term, it can implement a fuzzy search based on the search term, and searching by the search term can reduce the difficulty of the user's search.

[0050] In some other embodiments, the retrieved information includes a retrieved image. Accordingly, S120 may include: searching the 3D printing database for target 3D printing data to which the model list layout data matching the retrieved image belongs.

[0051] Specifically, the target three-dimensional printing data includes a layout view, and the layout view at least includes a three-dimensional model that matches the retrieval model in the retrieval image.

[0052] It is understandable that the user can input a search image into the electronic device. In this way, after obtaining the search image, the electronic device can perform a more accurate search based on the search image, so as to more accurately retrieve the three-dimensional printing data of the three-dimensional model that the user actually wants to retrieve, thereby improving the search accuracy. Moreover, when the user is unable to give a search term, the search can also be performed through the search image.

[0053] S130: Display at least part of the target three-dimensional printing data.

[0054] In some embodiments, S130 may include: displaying at least one process node control corresponding to at least part of the target 3D printing data; and displaying data under the process node corresponding to the target process node control in response to a triggering operation on the target process node control.

[0055] For example, when the user triggers the typesetting process node control, the model list typesetting data and the node information of the typesetting process node can be displayed; when the user triggers the slicing process node control, the node information of the slicing file and the slicing process node can be displayed; when the user triggers the sending process node control, the node information of the sending process node can be displayed; when the user triggers the printing process node control, the node information of the printing process node can be displayed.

[0056] Of course, in other embodiments, all target three-dimensional printing data may also be directly displayed.

[0057] Optionally, the method further includes: during the process of three-dimensional printing of the three-dimensional model, saving the three-dimensional printing data thereof into a three-dimensional printing database.

[0058] In this way, the 3D printing database can record the 3D printing data corresponding to each 3D printing, so that the 3D printing data can be stored effectively and uniformly. In addition, when the user wants to retrieve the 3D printing data of a certain 3D model later, the user can input the search information into the electronic device so that the electronic device can retrieve the 3D printing data of the 3D model based on the search information, which is convenient for the user to retrieve the 3D model with abnormal printing, and trace the problem based on the retrieved target 3D printing data, which is convenient for the user to perform quality control.

[0059] The disclosed embodiment can obtain the search information, and then search the target 3D printing data matching the search information in the 3D printing database, so as to display at least part of the target 3D printing data. It can be seen that by adopting the above technical solution, the target 3D printing data can be automatically searched in the 3D printing database based on the search information, without the need for the user to manually search the data in a time-consuming and laborious manner. In this way, the convenience of the user in searching the target 3D printing data can be improved, and the user can quickly analyze the cause of the printing abnormality of the model and quickly re-print the 3D printing.

[0060] Figure 2 This is a flow chart of another method for processing three-dimensional printing data provided by an embodiment of the present disclosure. The embodiment of the present disclosure is optimized on the basis of the above embodiment, and the embodiment of the present disclosure can be combined with various optional solutions in one or more of the above embodiments.

[0061] like Figure 2 As shown, the method for processing three-dimensional printing data may include the following steps.

[0062] S210, obtaining a retrieval image, wherein if the retrieval model is not removed from the printing platform, the retrieval image is obtained by collecting images of all three-dimensional models on the printing platform.

[0063] In the disclosed embodiment, if the three-dimensional model that the user wants to retrieve (i.e., the retrieval model) has not been removed from the printing platform, the user can perform image acquisition on all three-dimensional models on the printing platform to obtain a retrieval image. For example, an image acquisition device (such as a camera, etc.) can be used to perform image acquisition on the printing platform and all three-dimensional models thereon from at least one acquisition perspective, such as acquiring images from a frontal top view, a left front top view, a right front top view, a left rear top view, and / or a right rear top view.

[0064] S220, extracting feature information of all three-dimensional models on the printing platform from the search image.

[0065] Specifically, the feature information may include contour information of the 3D model. Of course, for a scenario where the retrieval model has not been removed from the printing platform, the feature information may also include position information of the 3D model on the printing platform, wherein the position information may be the coordinates of the center point of the 3D model in the image coordinate system established based on the printing platform, but is not limited thereto.

[0066] It should be noted that if there are multiple retrieval images corresponding to different acquisition perspectives, the feature information of all three-dimensional models on the printing platform can be first extracted from the retrieval image collected from the frontal view perspective; if the extraction fails, the feature information of all three-dimensional models on the printing platform is extracted from the retrieval image collected from other perspectives (such as left front view, right front view, left rear view, and / or right rear view, etc.). It can be understood that the probability of distortion of the image collected from the frontal view perspective is small, and even if distortion occurs, the degree of distortion is small. Therefore, the probability of successful extraction can be increased by preferentially extracting the feature information of all three-dimensional models on the printing platform from the retrieval image collected from the frontal view perspective.

[0067] Specifically, for a search image, there are many specific implementation methods for extracting feature information of all three-dimensional models on the printing platform from the search image. Typical examples are described below, but they do not constitute limitations on the present application.

[0068] In some embodiments, S220 may include: identifying an image region corresponding to the printing platform from the retrieved image; and extracting feature information of each three-dimensional model on the printing platform from the image region corresponding to the printing platform.

[0069] Specifically, an edge detection operator (such as Canny operator, Roberts operator, Sobel, etc.) may be used to perform edge detection on the search image to obtain an image region corresponding to the printing platform (ie, contour information of the printing platform).

[0070] Specifically, edge detection is performed on the image area corresponding to the printing platform using an edge detection operator (such as Canny operator, Roberts operator, Sobel, etc.) to obtain image areas (i.e., contour information) corresponding to all three-dimensional models on the printing platform. Of course, the position information of the three-dimensional model on the printing platform can also be determined based on the image area corresponding to the printing platform and the image area corresponding to the three-dimensional model.

[0071] It can be understood that by first identifying the image area corresponding to the printing platform and then extracting the feature information of each three-dimensional model on the printing platform from the image area corresponding to the printing platform, the feature information of the three-dimensional model can be extracted simply and quickly.

[0072] In some other embodiments, the retrieval image may be input into a pre-trained first feature extraction model, and feature information of all three-dimensional models in the retrieval image output by the first feature extraction model may be obtained.

[0073] S230 . Based on the feature information, select the three-dimensional model with the largest area from all the three-dimensional models on the printing platform as the target model.

[0074] Specifically, the areas corresponding to all three-dimensional models on the printing platform are determined based on the contour information, and then the three-dimensional model with the largest area is selected as the target model.

[0075] Of course, in other embodiments, a three-dimensional model may be randomly selected from all three-dimensional models on the printing platform as the target model, or the retrieval model may be used as the target model.

[0076] S240: Retrieve candidate 3D printing data that matches the feature information of the target model from the 3D printing database.

[0077] Specifically, the layout view in the candidate three-dimensional printing data includes at least one three-dimensional model, and the at least one three-dimensional model includes a three-dimensional model whose feature information matches the feature information of the target model.

[0078] Specifically, as described above, the 3D printing database stores 3D printing data, including layout views. For a layout view having the same acquisition perspective as the search image, when the layout view and the search image are adjusted to the same image size, a shape matching algorithm (i.e., matchShape) can be used to match the feature information of the target model with the 3D model in the layout view, and the 3D printing data corresponding to the layout view to which the 3D model matching the feature information of the target model belongs is determined as candidate 3D printing data.

[0079] It should be noted that if a piece of three-dimensional printing data includes layout views under multiple different acquisition perspectives, and the number of retrieval images is multiple and corresponds to different acquisition perspectives, the retrieval image captured under the top view perspective can be matched with the layout view first, that is, the shape matching algorithm (i.e., matchShape) is used to match the feature information of the target model extracted from the retrieval image captured under the top view perspective with the three-dimensional model in the layout view captured under the top view perspective; if the match fails, the retrieval image and layout view captured under other perspectives (such as left front top view, right front top view, left rear top view, and / or right rear top view, etc.) are selected for matching.

[0080] It is understandable that the larger the area, the more features and details there are on the three-dimensional model. Matching the three-dimensional model with the largest area as the target model can make the matched candidate three-dimensional printing data more accurate.

[0081] S250: Check whether the candidate 3D printing data matches the feature information of the retrieval model, and if so, determine the candidate 3D printing data as the target 3D printing data.

[0082] Specifically, as described above, the layout view in the candidate three-dimensional printing data includes at least one three-dimensional model. If the at least one three-dimensional model includes a three-dimensional model whose feature information matches the feature information of the retrieval model, the candidate three-dimensional printing data matches the retrieval model, otherwise it does not match.

[0083] It is understandable that by verifying whether the candidate three-dimensional printing data matches the retrieval model, the accuracy of the target three-dimensional printing data finally determined can be improved.

[0084] Of course, in other embodiments, S250 may include: checking whether the feature information of the three-dimensional model other than the target model on the printing platform matches the feature information of the three-dimensional model other than the target model in the candidate three-dimensional printing data; if so, determining that the candidate three-dimensional printing data matches the retrieval model.

[0085] Specifically, as described above, the layout view in the candidate three-dimensional printing data includes at least one three-dimensional model. If the at least one three-dimensional model corresponds one-to-one with all the three-dimensional models on the printing platform and the feature information matches, then the candidate three-dimensional printing data is the target three-dimensional printing model; otherwise, the candidate three-dimensional printing data is not the target three-dimensional printing data.

[0086] It is understandable that by verifying whether the candidate 3D printing data matches the feature information of the 3D model other than the target model on the printing platform, the accuracy of the target 3D printing data finally determined can be further improved.

[0087] It should be noted that when verifying whether the retrieval model, or each three-dimensional model other than the target model on the printing platform matches the candidate three-dimensional printing data, the verification can be preferentially performed based on the layout view that matches the target model. If the verification result is a mismatch, the verification can be performed based on the layout views under other acquisition perspectives.

[0088] S260: Display at least part of the target three-dimensional printing data.

[0089] Specifically, S260 is similar to S130 and will not be described in detail here.

[0090] The disclosed embodiment can use the 3D model with the largest area on the printing platform as the target model, that is, the 3D model with more details and features as the target model, and retrieve the candidate 3D printing data based on the target model, so that the retrieved candidate 3D printing data is more accurate. In addition, by verifying whether the candidate 3D printing data matches the feature information of the retrieval model, it is possible to further verify whether the candidate 3D printing data is the target 3D printing data, thereby further improving the accuracy of the target 3D printing data finally retrieved.

[0091] Figure 3 This is a flow chart of another method for processing three-dimensional printing data provided by an embodiment of the present disclosure. The embodiment of the present disclosure is optimized on the basis of the above embodiment, and the embodiment of the present disclosure can be combined with various optional solutions in one or more of the above embodiments.

[0092] like Figure 3 As shown, the method for processing three-dimensional printing data may include the following steps.

[0093] S310, obtaining a retrieval image, wherein if the retrieval model has been removed from the printing platform, the retrieval image is obtained by performing image acquisition on the retrieval model.

[0094] In the disclosed embodiment, if the three-dimensional model that the user wants to retrieve (i.e., the retrieval model) has been removed from the printing platform, considering that it is inconvenient for the user to find other three-dimensional models that are three-dimensionally printed together with the retrieval model, the user can perform image acquisition on the retrieval model to obtain a retrieval image. For example, an image acquisition device (such as a camera, etc.) can be used to acquire images of the retrieval model from at least one acquisition perspective, such as acquiring images from a frontal top view, a left front top view, a right front top view, a left rear top view, and / or a right rear top view.

[0095] S320: Extract feature information of the retrieval model from the retrieval image.

[0096] Specifically, the feature information may include contour information of the three-dimensional model.

[0097] It should be noted that if there are multiple retrieval images corresponding to different acquisition perspectives, the feature information of the retrieval model can be first extracted from the retrieval image acquired from the frontal overhead perspective; if the extraction fails, the feature information of the retrieval model can be extracted from the retrieval images acquired from other perspectives (for example, left front overhead view, right front overhead view, left rear overhead view, and / or right rear overhead view, etc.).

[0098] Specifically, for a search image, there are many specific implementation methods for extracting feature information of a search model from the search image. Typical examples are described below, but they do not constitute a limitation to the present application.

[0099] In some embodiments, an edge detection operator (eg, Canny operator, Roberts operator, Sobel, etc.) may be used to perform edge detection on the retrieval image to obtain an image region corresponding to the retrieval model (ie, contour information of the retrieval model).

[0100] In other embodiments, the retrieval image may also be input into a pre-trained second feature extraction model, and feature information of the retrieval model output by the second feature extraction model may be obtained.

[0101] S330 , searching the 3D printing database for target 3D printing data that matches the feature information of the search model.

[0102] Specifically, the layout view in the target three-dimensional printing data includes at least one three-dimensional model, and the at least one three-dimensional model includes a three-dimensional model whose feature information matches the feature information of the search model.

[0103] Specifically, as described above, the 3D printing database stores 3D printing data, including layout views. For a layout view having the same acquisition perspective as the search image, when the layout view and the search image are adjusted to the same image size, a shape matching algorithm (i.e., matchShape) can be used to match the feature information of the search model with the 3D model in the layout view, and the 3D printing data corresponding to the layout view to which the 3D model matching the feature information of the search model belongs is determined as the target 3D printing data.

[0104] It should be noted that if a piece of three-dimensional printing data includes layout views under multiple different acquisition perspectives, and the number of retrieval images is multiple and corresponds to different acquisition perspectives, the retrieval image captured under the top view perspective can be matched with the layout view first, that is, the shape matching algorithm (i.e., matchShape) is used to match the feature information of the retrieval model extracted from the retrieval image captured under the top view perspective with the three-dimensional model in the layout view captured under the top view perspective; if the match fails, the retrieval image and layout view captured under other perspectives (such as left front top view, right front top view, left rear top view, and / or right rear top view, etc.) are selected for matching.

[0105] S340: Display at least part of the target three-dimensional printing data.

[0106] Specifically, S340 is similar to S130 and will not be described in detail here.

[0107] The disclosed embodiment can extract the feature information of the retrieval model from the retrieval image, and then retrieve the target 3D printing data matching the feature information of the retrieval model in the 3D printing database. The retrieval based on the feature information of the retrieval model is simple and convenient, which is conducive to quickly obtaining the target 3D printing data.

[0108] Figure 4 1 is a schematic diagram of a structure of a 3D printing data processing device provided by an embodiment of the present disclosure. The 3D printing data processing device can be understood as the above-mentioned electronic device or a part of the functional modules in the above-mentioned electronic device. Figure 4 As shown, the 3D printing data processing device 400 includes:

[0109] A first acquisition module 410, used to acquire search information;

[0110] A first retrieval module 420 is used to retrieve target 3D printing data matching the retrieval information in the 3D printing database;

[0111] The first display module 430 is used to display at least part of the target 3D printing data.

[0112] In some other implementations, the first acquisition module 410 is specifically used to acquire a search term, wherein the search term includes node information of each process node in a process of performing three-dimensional printing on a three-dimensional model;

[0113] or;

[0114] A retrieval image is obtained, wherein the retrieval image at least includes an image area corresponding to the retrieval model.

[0115] In some further embodiments, if the retrieval model is not removed from the printing platform, the retrieval image is obtained by performing image acquisition on all three-dimensional models on the printing platform;

[0116] The first search module 420 may include:

[0117] A first extraction submodule, used to extract feature information of all three-dimensional models on the printing platform from the search image;

[0119] A first matching submodule, configured to retrieve candidate 3D printing data matching the feature information of the target model from the 3D printing database;

[0120] The first verification submodule is used to verify whether the candidate 3D printing data matches the feature information of the retrieval model, and if so, determine the candidate 3D printing data as the target 3D printing data.

[0121] In some further embodiments, the first extraction submodule is specifically used to identify the image area corresponding to the printing platform from the search image;

[0122] Feature information of each three-dimensional model on the printing platform is extracted in the image area corresponding to the printing platform.

[0123] In some further implementations, the first syndrome module is specifically configured to:
