Problems solved by technology

If the software is directly used for modeling without on-site measurement, the deviation of the model size will be relatively large, which will have a relatively large adverse effect on the decoration effect
At present, the mainstream home improvement software does not have the function of quickly measuring and automatically modeling the room on the spot

Embodiment 1

[0054] Please refer to Figure 1 to Figure 3 , this embodiment provides a method for measuring the internal dimensions of a cubic room.

[0055] First, in this embodiment, the corresponding figure 1 In the spatial position shown, define the coordinates of the four corners where the user faces the wall from the upper left, upper right, lower left, and lower right to V 1 , V 2 , V 3 , V 4 ;Define the coordinates of the 4 corners where the user is facing away from the wall in order from upper left, upper right, lower left, and lower right respectively as V 5 , V 6 , V 7 , V 8 ;

[0056] Taking the user's eye position as the origin of the three-axis coordinate system, the spatial coordinate value of the corner can be represented by {x,y,z}, such as figure 2shown.

[0057] Then V 1 to V 8 Represents the 8 corner vector values ​​of a cubic room, that is, the spatial coordinate values ​​{x, y, z} of each corner, and its specific expression is as follows:

[0058] V 1 =...

Embodiment 2

[0098] Please refer to Figure 4 , on the basis of the first embodiment, this embodiment further optimizes the accuracy of the finally acquired data that is closest to the real room size, that is, the gap between the three-dimensional array acquired in S7 and the real room size.

[0099] Specifically, in the method of this embodiment, the same steps as those in Embodiment 1 will not be repeated here. For details, please refer to the description of Embodiment 1. The difference is that after S7, the following steps are further included:

[0100] S8: The three-dimensional array with the highest similarity obtained in the previous step is used as a seed, and a second preset number of three-dimensional arrays is randomly generated according to the preset precision value;

[0101] Specifically, using the three-dimensional array B={b1, b2, b3} acquired by S7 as a seed, randomly generate a second preset number of three-dimensional arrays according to the preset precision value of the ...

Embodiment 3

[0114] On the basis of Embodiment 1 and Embodiment 2, this embodiment provides a computer storage medium on which a computer program is stored, and when the computer program is executed by a processor, the foregoing Embodiment 1 and / or Embodiment 2 are implemented. The steps involved in the described method for measuring the interior dimensions of a cubical room.

[0115] The storage medium may be a magnetic disk, an optical disk, a read-only memory (Read-Only Memory, ROM) or a random access memory (Random Access Memory, RAM), etc.

[0116] In summary, the method for measuring the internal dimensions of a cubic room and the storage medium provided by the present invention can not only quickly and automatically measure and obtain the dimension data of a cubic room through software in a simple and easy way, but also has the characteristics of easy operation; and The accuracy of the final measurement result can be flexibly adjusted according to the user-defined accuracy, which ca...

Abstract

The invention provides a cubic room internal dimension measurement method and a storage medium. The method comprises the following steps: S1, recording first vector values obtained when a display screen center aligns each corner of a room respectively; S2, randomly generating a first preset number of three-dimensional array; S3, calculating the second vector value of each corner by taking the display screen center as the origin of a three-dimensional coordinate system according to each three-dimensional array; S4, performing unit processing on the second vector values; S5, calculating a unit vector deviation between a unit second vector value and the first vector value corresponding to each three-dimensional array; S6, calculating the similarity according to the unit vector deviation corresponding to each three-dimensional array; and S7, acquiring three-dimensional arrays with the highest similarity. Through adoption of the cubic room internal dimension measurement method, accurate dimension data of a cubic room can be quickly and automatically measured by software in a simple and feasible way. The method has the characteristics of easiness and convenience in operation, meeting ofdifferent requirements and high practicability.

Description

technical field [0001] The invention relates to the technical field of house decoration, in particular to a method for measuring the internal dimensions of a cubic room and a storage medium. Background technique [0002] In the room decoration effect model displayed by the home decoration software, the decorated room structure model needs to be measured on the spot and then manually modeled by the designer, which requires a lot of work in the early stage of modeling. If the software is directly used for modeling without on-site measurement, the deviation of the model size will be relatively large, which will have a relatively large adverse effect on the decoration effect. At present, the mainstream home improvement software does not have the function of quickly measuring and automatically modeling the room on the spot. [0003] Therefore, it is necessary to provide a method and a computer-readable storage medium of the corresponding computer program that can be applied to h...
