All falling within the scope of the present invention.

As shown in fig. 1, the method for calculating a demolished wall provided by the present invention includes:

The first embodiment is as follows:

as shown in fig. 2 to 7, the present embodiment takes reading the original house type data as an example, and the principle of reading the decoration design data is the same, which is not repeated herein.

Wall Wa is composed of six control points (Pa1-Pa6), two parallel segments (Sa1, Sa2), and Wa can be represented as a closed space (Pa1, Pa2, Pa3, Pa4, Pa5, Pa6, Pa 1). The connected walls are point-combined to form a larger closed space Cn, and the closed spaces are combined into a group G1, which is the final data of the house type.

1) If the wall Wa is directly connected with the wall Wb, it is necessary to combine Wa ═ with (Pa1, Pa2, Pa3, Pa4, Pa5, Pa6, Pa1), Wb ═ with (Pb1, Pb2, Pb3, Pb4, Pb5, Pb6, Pb1), Wa and Wb exist at the same position: pa 2-Pb 2, Pa 3-Pb 3, Pa 4-Pb 4. Wa and Wb combined to give Ca ═ Ca (Pa1, Pa2, Pb1, Pb6, Pb5, Pb4, Pa5, Pa6, Pa 1).

2) If the walls Wa, Wb and Wc are directly connected, it is necessary to combine Wa ═ Pa1, Pa2, Pa3, Pa4, Pa5, Pa6 and Pa1, Wb ═ Pb (Pb1, Pb2, Pb3, Pb4, Pb5, Pb6 and Pb1), and Wc ═ Pc (Pc1, Pc2, Pc3, Pc4, Pc5, Pc6 and Pc 1). The points Pa2, Pb2, Pa3, Pb3, Pc3, Pb4, Pc2 and Pa4, Pc4 of Wa, Wb and Wc are in the same position. The combination of Wa, Wb, Wc yields Cb ═ (Pa1, Pa2, Pb1, Pb6, Pb5, Pb4, Pc1, Pc6, Pc5, Pc4, Pa5, Pa6, Pa 1).

3) If the walls Wa, Wb, Wc, and Wd are directly connected, it is necessary to combine Wa ═ (Pa1, Pa2, Pa3, Pa4, Pa5, Pa6, Pa1), Wb ═ (Pb1, Pb2, Pb3, Pb4, Pb5, Pb6, Pb1), Wc ═ (Pc1, Pc2, Pc3, Pc4, Pc5, Pc6, Pc1), Wd ═ (Pd1, Pd2, Pd3, Pd4, Pd5, Pd6, Pd 1). Pa 2-Pb 2, Pa 3-Pb 3-Pc 3-Pd 3, Pb 4-Pc 2, Pd 2-Pc 4, and Pd 4-Pa 4 exist at the same position of Wa, Wb, Wc, and Wd. Wa, Wb, Wc, and Wd combined to give Cd ═ (Pa1, Pa2, Pb1, Pb6, Pb5, Pb4, Pc1, Pc6, Pc5, Pc4, Pd1, Pd6, Pd5, Pd4, Pa5, Pa6, Pa 1).
