The home decoration industry is rapidly digitalized and informationized, the design and production are thoroughly completed, and after the design of a merchant designer is completed, data can be directly imported into factory equipment to carry out production installation. This requires accurate calculation information to be provided to the factory equipment, and errors of a few millimeters can cause failure of factory production, which brings serious losses to manufacturers.

However, as an important component in home decoration design, there is no platform currently available that can directly use design data to obtain accurate table production dimensions. When the size of the table top is output, the existing design platform can only output the size of the upper area of the table top and does not contain the water retaining width; nor can the entire mesa be cut to a size suitable for production. Therefore, a material calculating method capable of directly outputting the accurate size of the table top is needed.

The existing problems are as follows:

(1) When a merchant calculates materials on the table top, the calculated materials are required to contain the water retaining width so as to obtain more accurate quotation data and size information for production;

(2) The size of the raw materials is limited, but the size of the table surface designed by a designer may exceed the limit, and a merchant needs to cut the table surface according to the size so as to obtain size information which can be used for production;

(3) Various special-shaped table tops such as L-shaped table tops and U-shaped table tops exist, when the table tops are reproduced, the table tops cannot be produced according to a whole block, cutting is needed, and each segmented sub-block is produced respectively;

(4) The direction of the table board cut by the user may be inconsistent, and during production, the table board needs to be rotated according to the direction of the board, so that the production size is redetermined.

The invention will be described in detail below with reference to the attached drawings:

1. scene arrangement

The designer designs a scheme according to the opinion of the house owner, and the scheme comprises two tables. There is an L-shaped table cut into 3 pieces (as shown in fig. 2) and a rotated table with arc segments (as shown in fig. 3). And both table tops are provided with front water retaining plates.

2. Automatic calculating material

Both the designer and the factory's production docking machine will trigger an automatic calculation algorithm to generate a checklist or direct production docking. In this embodiment, the following logic will be run:

2.1 traversing all the table tops in the proposal, respectively calculating the materials

2.2L type cutting table material calculating.

2.2.1 extracting the height information of the water retaining from the contour information of the water retaining

2.2.2 calculating the area of the Table overall

2.2.2.1 traversing each edge of the table to find an edge that if it has a front water stop, then it is marked as an edge that needs to extend outwards according to the front water stop height.

2.2.2.2 extending outwardly from the mesa overall area. And (5) expanding each side needing to be extended outwards to obtain a new whole area of the table top.

2.2.2.3 determines whether rotation is required. If the table top is rotated, the region to which the table top is rotated is restored according to the same rotation angle, and the model is not rotated and does not need to be restored.

2.2.3 since the table is cut, the area of the cut table sub-blocks needs to be calculated, each sub-block of the table is traversed

2.2.3.1 traverses each edge of the mesa sub-block. And determining whether the edge needs to be extended according to the front water retaining according to the cutting line, the original edge of the table top and the intersecting and collinear relation between the edges, and marking the edge as the required extension.

2.2.3.2 extend outwardly of the area of the mesa sub-block resulting in an extended area of the mesa sub-block.

2.2.3.3 intersection of extended mesa sub-block region and mesa bulk region to filter the portion of mesa sub-block extending beyond bulk.

2.3.2.2 the procedure of step 2.2.2.2 was repeated.

2.3.2.3 steps are repeated 2.2.2.3, but here the table is rotated 45 ° clockwise, so the entire table area needs to be rotated 45 ° counter-clockwise in order to restore the area before rotation.

2.3.3 because this mesa is not cut, no sub-blocks need to be traversed.

2.3.4 obtaining the size of the region bounding box of the mesa according to the rotated mesa region, and taking the size as the calculation result of the mesa

And 2.4, calculating quotation according to the calculation result of the steps, and outputting a list and production data.
