[0057] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0059] like Figure 1 FIG. 1 is a schematic diagram of an implementation flow of a method for recognizing a table top contour shape provided by an embodiment of the present invention. The method is applied to a processor and may specifically include the following steps:

[0060] S101, obtaining countertop models involved in a decoration plan, and determining a countertop model to be identified in the countertop models.

[0061] In an embodiment of the present invention, a user (eg, a designer) can use home design software to perform home decoration design, thereby generating a certain decoration plan. Before generating the design data of the production process, a countertop model involved in the decoration plan can be obtained.

[0062] It should be noted that the countertop model involved in the decoration plan can have various shapes, such as rectangular, L-shaped or U-shaped. Figure 2 As shown, the embodiments of the present invention are not limited to this.

[0063] For the countertop models involved in the decoration plan, the embodiment of the present invention needs to determine the countertop models to be identified in the countertop models. For example, for the countertop models involved in the kitchen decoration plan, the countertop models to be identified in the countertop models are determined.

[0064] Specifically, the embodiments of the present invention can determine the table top model to be identified in the table top model in the following manner: determine whether the table top model is segmented; if the table top model is segmented, obtain (several) sub-table top models after the table top model is segmented, and determine (several) sub-table top models as the table top model to be identified; if the table top model is not segmented, determine the table top model as the table top model to be identified.

[0065] For example, for a countertop model involved in a kitchen decoration plan, the embodiment of the present invention determines whether the countertop model is segmented, such as Figure 3 As shown, assuming that the tabletop model is segmented, it means that the tabletop model is segmented, and four sub-tabletop models after the tabletop model is segmented are obtained, and the four sub-tabletop models are determined to be the tabletop models to be identified.

[0066] In addition, assuming that the tabletop model has not been segmented, it means that the tabletop model has not been segmented. In this case, the entire tabletop model can be identified as a whole, that is, the tabletop model is determined to be the tabletop model to be identified.

[0067] In the embodiment of the present invention, after the table top model is segmented, the segmentation line and the table top model outline have intersection points, and these intersection points can form a segmentation point array. For example, if a rectangular table top model is cut in the middle, the segmentation line and the rectangular table top model have two intersection points, such as Figure 4 As shown, the segmentation point array is formed.

[0068] Based on this, the embodiment of the present invention can obtain the table top data corresponding to the table top model and determine whether the table top data includes a segmentation point array. If the table top data includes a segmentation point array, it can be determined that the table top model is segmented. If the table top data does not include a segmentation point array, it is determined that the table top model is not segmented.

[0069] S102, selecting a target tabletop model from the tabletop models to be identified, and determining a minimum rectangular bounding box surrounding the target tabletop model.

[0070] For the table top models to be identified, some table top models may not need to be identified, such as rectangular table top models. Therefore, in the embodiment of the present invention, it is necessary to filter the target table top model from the table top models to be identified in order to identify the contour shape.

[0071] It should be noted that, in the embodiment of the present invention, the number of countertop models to be identified can be multiple, such as the several sub-countertop models mentioned above, so that the target countertop model can be screened from the multiple countertop models to be identified, and the embodiment of the present invention is not limited to this.

[0072] Among them, for a rectangular table top model, there are generally 4 contour points, that is, 4 vertices correspond to 4 contour points. The number of contour points is relatively small, and it does not belong to an anisotropic (i.e. U-shaped or L-shaped) table top model. For a table top model with a large number of contour points, it is highly likely to belong to an anisotropic (i.e. U-shaped or L-shaped) table top model. Based on this, the target table top model can be screened from the table top models to be identified.

[0073] Specifically, for a tabletop model to be identified, in the embodiment of the present invention, the number of contour points corresponding to the tabletop model to be identified is obtained, and it is determined whether the number of contour points is greater than or equal to a preset number threshold.

[0074] If the number of contour points corresponding to the table model to be identified is greater than or equal to a preset number threshold, the table model to be identified can be determined as a target table model, which means that subsequent processes can be executed on it.

[0075] If the number of contour points corresponding to the countertop model to be identified is less than the preset threshold, the countertop model to be identified can be eliminated, which means that there is no need to execute subsequent processes on it, and only the countertop models to be identified whose number of contour points is greater than or equal to the preset threshold need to be screened out.

[0076] For example, the countertop model to be identified is a rectangular countertop model. The embodiment of the present invention obtains the number of contour points corresponding to the countertop model to be identified (4) and presets the number threshold (5). It can be seen that the number of contour points corresponding to the countertop model to be identified is less than the preset number threshold. At this time, the countertop model to be identified can be eliminated, which means that there is no need to execute subsequent processes on it, and it is only necessary to screen out the countertop models to be identified whose number of contour points is greater than or equal to 5.

[0077] For example, the countertop model to be identified is an L-shaped countertop model. The embodiment of the present invention obtains the number of contour points corresponding to the countertop model to be identified (6) and the preset number threshold (5). It can be seen that the number of contour points corresponding to the countertop model to be identified is greater than the preset number threshold. At this time, the countertop model to be identified is determined to be the target countertop model, which means that the subsequent process can be executed on it.

[0078] In addition, in the embodiment of the present invention, for the target table model, the minimum rectangular bounding box surrounding the target table model is determined. A minimum rectangular bounding box that can completely surround the target table model can be created, so that the minimum rectangular bounding box surrounding the target table model can be determined.

[0079] For example, for the target table model, that is, the L-shaped table model, create a minimum rectangular bounding box that can completely surround the target table model, such as Figure 5 As shown, the minimum rectangular bounding box surrounding the target table model can be determined.

[0080] S103, using the minimum rectangular bounding box to crop the target table model to obtain a cropped contour result, and compare it with the target table model contour.

[0081] In the embodiment of the present invention, for the target table model, the target table model can be clipped using a minimum rectangular bounding box to obtain a clipped contour result. The clipping method here can be a Boolean operation, which is not limited in the embodiment of the present invention.

[0082] Specifically, for the target table model, the minimum rectangular bounding box can be used to perform Boolean operations on the target table model to obtain a difference set to obtain a clipped contour result. The specific processing of the Boolean operation can refer to the processing flow on the market, and the embodiment of the present invention will not be repeated here.

[0083] For example, for the target table model, i.e., the L-shaped table model, the minimum rectangular bounding box is used to perform Boolean operations on the target table model to obtain the difference set to obtain the contour result after clipping. The contour result here can be as follows: Figure 6 Dotted line shown.

[0084] In addition, for the cropped contour result, the embodiment of the present invention compares the cropped contour result with the target table model. The comparison here specifically performs edge-to-edge coincidence detection, that is, the cropped contour result and the target table model perform edge-to-edge coincidence detection, where the edge refers to the contour edge.

[0085] S104: Identify the contour shape of the target tabletop model according to the comparison result, and trigger a prompt according to the contour shape.

[0086] Regarding the comparison result between the cropped contour result and the target table top model, the embodiment of the present invention can identify the contour shape of the target table top model according to the comparison result, and trigger a corresponding prompt according to the contour shape.

[0087] In this embodiment of the present invention, the (contour) edges that overlap the cropped contour result and the target table model contour are determined, and the number of the overlapping edges is obtained, and then it is determined whether the number of the overlapping edges is greater than or equal to a preset edge threshold.

[0088] If the number of overlapping edges is greater than or equal to the preset edge threshold, it means that the contour shape of the target table model is heterogeneous, that is, the contour shape of the target table model is U-shaped or L-shaped; if the number of overlapping edges is less than the preset edge threshold, it is determined that the contour shape of the target table model is non-U-shaped or non-L-shaped.

[0089] For example, for the clipped contour result, such as Figure 6 The dotted line shown in FIG. 1 is used to perform an edge-to-edge coincidence detection on the contour result after cropping and the target table model, thereby determining the (contour) edge where the contour result after cropping coincides with the contour of the target table model, that is, Figure 6 The dotted line shown means that the number of the overlapping edges is 2. The number of the overlapping edges is obtained, and then it is determined whether the number of the overlapping edges is greater than or equal to the preset edge threshold. Here, it is assumed that the preset edge threshold is 2, indicating that the number of the overlapping edges is equal to the preset edge threshold, which means that the contour shape of the target table model is heterogeneous, that is, the contour shape of the target table model is L-shaped.

[0090] In addition, when the contour shape of the target countertop model is U-shaped or L-shaped, a prompt is triggered to remind the user that this situation requires further cutting, that is, the target countertop model needs to be further cut to meet the needs of automated production process without manual review; otherwise, when actual production begins, it will be discovered that the data does not meet production needs, and the wrong countertop will be produced or no production will be performed, resulting in an erroneous production order; ultimately, the user can only return to the design stage for modification, which will seriously affect automated production without manual review.

[0091] Through the above description of the technical solution provided by the embodiment of the present invention, the countertop model involved in the decoration plan is obtained, and the countertop model to be identified in the countertop model is determined, the target countertop model is screened from the countertop model to be identified, and the minimum rectangular bounding box surrounding the target countertop model is determined, the target countertop model is cropped using the minimum rectangular bounding box to obtain the cropped contour result, and the contour result is compared with the target countertop model contour, the contour shape of the target countertop model is identified according to the comparison result, and a prompt is triggered according to the contour shape.

[0092] By identifying the contour shape of the countertop model in this way, the U-shaped or L-shaped countertop model that is difficult to meet the production process requirements can be quickly identified, and prompts can be triggered based on the contour shape to perform accurate detection before generating actual production data, so as to achieve the purpose of allowing users to improve the design again, avoid generating overly complex design data that is difficult to meet the production process, and avoid wasting resources and labor costs. The subsequent on-site splicing and installation of the countertop with a U-shaped or L-shaped contour is relatively simple and convenient.
