Description

[Technical field]

[0001] The present invention relates to the field of residential environment design, and more particularly to a residential environment design system based on digitalization. The present invention also relates to a residential environment design method based on digitalization. [Background technology]

[0002] Living environment design is the design of the living environment, and the most common is interior design. Interior design utilizes material, technical means and architectural design principles according to the building's purpose, location environment and corresponding standards to create an indoor environment that is functional, reasonable, comfortable and beautiful, and meets people's material and spiritual needs. Currently, the interior design process is complicated, and it is very inconvenient to explain the design to the user through pictures and text. In many cases, the user's needs cannot be fully met after actual construction due to errors in user understanding, which causes subsequent rework to waste resources and time. Therefore, a digital-based living environment design system and method are provided.

[0003] Regarding digital or VR technology-based design, the invention specification of the publication number CN110837673A in the China Patent Pool discloses a garden landscape design system based on VR technology, but the system mainly describes garden design correspondingly, and does not design interior design and architectural design.

[0004] It is due to the landscape design subsystem including a functional area division module, a vegetation planning module and an architectural planning module. The present invention introduces VR technology into the construction of a 3D model of garden landscape design, so that the real scene can be viewed directly without the need to go to the site, only with VR glasses, thereby improving the efficiency of the 3D model, and the landscape design is carried out by dividing the area, so that the design is regular and efficient. This patent mainly considers multiple factors when planning vegetation, thereby ensuring the rational planting of vegetation in the growing environment and landscaping under the condition of effectively utilizing existing resources. Considering the vegetation layout and architectural layout between the areas, the rational layout of vegetation and architecture is carried out overall. In addition, although gardens and living environments are related, they are mainly for viewing and leisure, and the patent does not mention the design of the main living environment of buildings and indoors, and the scenes are also different, making it difficult to follow.

A digital-based residential environment design system according to claim 1.

6. A method for using the design system according to any one of claims 1 to 5, comprising the steps of: Step 1: measuring living environment data by a data input subsystem, inputting the measured data, and transmitting the data in a digital form to a design subsystem; Step 2 in which the design subsystem establishes a three-dimensional model based on the environmental data input by the data input subsystem; Step 3, the design subsystem performs a rudimentary illumination rendering on the established 3D model to provide it with basic illumination; A step 4 of selecting the required design type and completing the design, An automatic design type that introduces a floor plan similar to the actual living environment data through a floor plan entry module, selects a model floor plan and model room that meets the conditions from the design database, and automatically designs the user's own room based on the selected model room; Step 4 includes a manual design type in which a jig and building material template is selected from a design database to manually decorate the room; Step 5: a user wears a hardware device of the VR experience subsystem and interacts with the VR experience subsystem with the completed three-dimensional model, thereby allowing the user to experience the designed living environment; Step 6: based on the user's feedback, modify the 3D model using manual design type, and perform two trials until the user is satisfied. A method for designing a living environment based on digitalization.

7. The measurement of the living environment data by the data input subsystem described in step 1 is performed using a three-dimensional laser. The specific method is as follows: 1) Preprocessing the massive amount of point cloud data obtained by 3D laser scanning to determine the point cloud data in the target area; 2) Dividing and managing the point cloud data in the target area according to floors, dividing rooms into the floors, and encoding and managing the room data according to an actual scene; 3) Extracting feature information of each room on each floor from the blocked point cloud data corresponding to each room; 7. The method for designing a living environment based on digitization according to claim 6.

8. Specifically, dividing the floor into rooms and encoding and managing the room data according to an actual scene includes the following steps: 1) setting names for each room in the target area based on a floor plan of the target area; 2) Isolating and extracting the smallest planar elements for each room; 3) drawing the structure of the target area, each room and the smallest planar element within the room by tree nodes; 8. The method for designing a living environment based on digitization according to claim 7.
