[0035] The following details the embodiments of the present invention. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0036] A method for automatically docking and positioning parametric cabinets for customized furniture, comprising the following steps:

[0037] Step S1: Obtain all cabinet units in the three-dimensional scene, where the cabinet units include information about all sides;

[0038] Step S2: Traverse and read the information about all sides of each cabinet unit;

[0039] Step S3: Calculate all positioning angle attributes of each cabinet unit according to the information about all sides of each cabinet unit, where the positioning angle attributes include the left front angle, the right front angle, the left rear angle, and the right rear angle;

[0040] Step S4: Receive an instruction from the user to create and position a parametric cabinet in the three-dimensional scene, or a confirmation instruction to select a cabinet unit in the scene as the cabinet unit to be arranged, receive an operation instruction from the user to drag the cabinet unit to be arranged with the mouse cursor, and determine whether the distance between the cursor point and the positioning angle points corresponding to the positioning angles of other cabinet units is less than a limit value. If so, perform matching according to the positioning matching method; if the distances between the cursor point and the positioning angle points corresponding to the positioning angles of multiple other cabinet units are all less than the limit value, then match with the positioning angle of the cabinet unit with the smallest distance value;

[0041] Step S5: Convert the positioning angle of the cabinet unit to be arranged to the positioning angle of the target cabinet unit that matches the cabinet unit to be arranged through coordinate transformation, and the docking and positioning of the cabinet unit to be arranged is completed.

[0042] A method for automatically docking and positioning parametric cabinets for customized furniture in this solution, as Figure 1 shown, obtains all cabinet units in the three-dimensional scene. The cabinet units include information about all sides. In one embodiment, as Figure 2 shown, the rear side, the front side, the left side, and the right side of the cabinet unit are specified in the counterclockwise direction, which facilitates the subsequent definition of each positioning angle attribute in the cabinet unit. Specifically, p1p2 is the rear side of the unit cabinet, p2p3 is the left side of the unit cabinet, p3p4 is the front side of the unit cabinet, and p4p1 is the right side of the unit cabinet. Therefore, p1p2 and p2p3 form the left rear angle, p1p2 and p4p1 form the right rear angle, p2p3 and p3p4 form the left front angle, and p4p1 and p3p4 form the right front angle.

[0043] First, read the information of all sides of the first cabinet unit, and calculate all the positioning angle attributes of this cabinet unit. The positioning angle attributes include the left front angle, the right front angle, the left rear angle, and the right rear angle. Then, read the second cabinet unit and calculate all the positioning angle attributes of the second cabinet unit, and so on until all cabinet units are read. When the user arranges the cabinet units in the three-dimensional scene, move the mouse cursor point to drag and arrange a cabinet unit, and find the positioning angle whose distance from the mouse cursor point is less than the limit value among the positioning angle points of other cabinet units, and match it with the above. Convert the positioning angle of the arranged cabinet unit to the positioning angle of the target cabinet unit that matches the arranged cabinet unit through coordinate transformation, so as to achieve the fast and accurate docking and positioning of the cabinet unit.

[0044] This solution realizes the fast and accurate docking and positioning of the cabinet unit by matching the cursor point of the arranged cabinet unit with the corresponding positioning angle point of the target cabinet unit, which can effectively solve the problems of cumbersome operation in the traditional docking and positioning technology, and easy occurrence of misoperation leading to positioning errors and then design errors.

[0045] Preferably, in step S4, the limit value is specifically 100 pixel points.

[0046] In this embodiment, the judgment of the distance between the cursor point of the arranged cabinet unit and the corresponding positioning angle point of the positioning angle of other cabinet units is actually the judgment of the screen pixel distance. When the distance between the cursor point of the arranged cabinet unit and the corresponding positioning angle point of the positioning angle of other cabinet units is less than 100 pixel points, the positioning angle of the arranged cabinet unit is in contact with the positioning angle of the corresponding matching cabinet unit, and the effect after the matching positioning of the two is displayed, which is convenient for the user to operate.

[0047] Further explanation, if the distances between the cursor point of the arranged cabinet unit and the corresponding positioning angle points of multiple positioning angles in other cabinet units are all within 100 pixel points, then select the positioning angle with the smallest distance to match the arranged cabinet unit.

[0048] Preferably, in step S4, the positioning matching methods include the left front angle of the arranged cabinet unit matching the right front angle of the target cabinet unit, the left rear angle of the arranged cabinet unit matching the right rear angle of the target cabinet unit, the right front angle of the arranged cabinet unit matching the left front angle of the target cabinet unit, and the right rear angle of the arranged cabinet unit matching the left rear angle of the target cabinet unit. Specifically, the positioning matching method is unique, which is conducive to aligning and positioning the front or rear sides of each cabinet unit and preventing multiple cabinet units from overlapping and stacking.

[0049] Preferably, in step S5, it specifically includes the following steps:

[0050] Step S51: Establish a first coordinate system with the positioning corners of the arranged cabinet unit corresponding to the positioning corner points;

[0051] Step S52: Establish a second coordinate system with the positioning corners of the target cabinet unit corresponding to the positioning corner points;

[0052] Step S53: Convert the first coordinate system into the second coordinate system through matrix transformation.

[0053] Specifically, the coordinate conversion method is an existing 3D editing technology. In one embodiment, as Figure 3 shown, set the second cabinet 2 as the arranged cabinet unit, and set the first cabinet 1 as the target cabinet unit that matches the arranged cabinet unit. The left rear corner of the second cabinet 2 matches the right rear corner of the first cabinet 1. Among them, the corner point e corresponding to the left rear corner of the second cabinet 2 and the two corresponding sides he and ef form the first coordinate system, and the corner point d corresponding to the right rear corner of the first cabinet 1 and the two corresponding sides cd and da form the second coordinate system. By converting the first coordinate system into the second coordinate system through matrix transformation, the docking and positioning of the second cabinet 2 are completed.

[0054] Preferably, it further includes a setting step: setting the positioning corners of the arranged cabinet unit that has completed positioning and the positioning corners of the target cabinet unit that matches it as non-docking associated attributes. Specifically, set the two positioning corners that have completed matching as non-docking associated attributes, so that these two positioning corners will not participate in the matching during the next matching operation, avoiding interference operations and misoperations.

[0055] On the other hand, the present application provides a system for automatically docking and positioning parametric cabinets for customized furniture, and the system includes:

[0056] An acquisition module, used to acquire all cabinet units in the 3D scene;

[0062] A matching module for matching the positioning corners of two cabinet units according to the positioning matching method;

[0063] A conversion module for converting the positioning corner of the arranged cabinet unit to the positioning corner of the target cabinet unit that matches the arranged cabinet unit through coordinate conversion.

[0064] Specifically, the system includes an acquisition module, a reading module, a calculation module, a first receiving module, a second receiving module, a judgment module, a matching module, and a conversion module. The cooperation of each module realizes the rapid and accurate docking positioning of the cabinet unit.

[0065] Preferably, the conversion module includes a first creation sub-module, a second creation sub-module, and a conversion sub-module; the first creation sub-module is used to establish a first coordinate system for the positioning corner corresponding to the positioning corner point of the arranged cabinet unit, the second creation sub-module is used to establish a second coordinate system for the positioning corner corresponding to the positioning corner point of the target cabinet unit, and the conversion sub-module is used to convert the first coordinate system into the second coordinate system through matrix transformation.

[0066] Specifically, the conversion module includes a first creation sub-module, a second creation sub-module, and a conversion sub-module. The cooperation of each module realizes the conversion of the positioning corner of the cabinet unit that has been matched with the arranged cabinet unit to the target positioning corner of the arranged cabinet unit through coordinate conversion.

[0067] Preferably, it further includes a setting module for setting the positioning corner of the arranged cabinet unit that has completed positioning and the positioning corner of the target cabinet unit that matches it as a non-docking association attribute.

[0068] Specifically, the setting module sets the two positioning corners that have been matched as non-docking association attributes, and these two positioning corners will not participate in the matching during the next matching operation, avoiding interference operations and misoperations.
