Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for virtual three-dimensional modeling of houses using depth cameras fail to capture detailed information of functional spaces, leading to incomplete understanding of the house's structure and layout.
Innovation Solution
A method involving the acquisition of depth images and pictures from multiple angles within each functional space, using a processor to create a virtual 3D model and panoramic images, which are then sent to a terminal device upon request, allowing users to view the structure and details of the house.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If depth image collection is used for virtual 3D modeling, then the overall structure of the house can be captured, but the details of each functional space cannot be collected finely
Solution Approach 1:
The patent divides the house into multiple functional spaces (living room, bedroom, kitchen, etc.) and collects images separately for each space. This segmentation allows detailed capture of each functional area while maintaining the overall structure, resolving the contradiction between capturing overall structure and collecting fine details.
Solution Approach 2:
The patent combines depth images (3D spatial information) with regular pictures (2D detailed visual information) to create a comprehensive model. By adding the dimension of regular images alongside depth images, the system captures both structural and detailed information simultaneously.
2Ease of manufacture
If only depth images are collected, then the modeling process is simple, but users cannot comprehensively learn about each functional space
Solution Approach 1:
The patent merges depth image collection with regular picture collection into a unified process. Both types of images are acquired simultaneously using the same photographing spots, maintaining process simplicity while enriching the information content through combination of different image types.
Solution Approach 2:
The system uses a universal photographing approach that serves multiple functions: depth images provide 3D structure while regular pictures provide detailed visual information. This multi-functional collection method eliminates the need for separate detailed photography processes.
3Measurement precision
If multiple photographing spots are used to capture details, then functional space details improve, but data collection complexity increases
Solution Approach 1:
The patent performs preliminary selection of photographing spots based on the house layout and functional spaces. By pre-determining optimal positions before actual photography, the system captures necessary details without requiring excessive photographing spots, thus reducing collection complexity while maintaining detail precision.
Solution Approach 2:
The system creates a comprehensive digital model by collecting data at multiple spots and combining them into a unified virtual representation. This copying approach allows detailed capture across multiple locations while managing complexity through centralized data integration and processing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enables comprehensive data collection and model generation, allowing users to view both the overall structure and specific details of each functional space, improving the accuracy and completeness of the virtual house model.
Implementation Method 1
a camera that measures a distance between a photographing spot and the camera through the principle of structured light. The basic principle of structured light technique is as follows: a grating is placed outside a laser, and laser is refracted when being projected by the grating for imaging

AI summary
Embodiments of the present disclosure disclose a method for data collection and model generation of a house. According to the method, when a model of a house is to be established, both collected depth images of the house and pictures of the house are acquired. A virtual three-dimensional model of the house is created by using the depth images, and a panoramic image of a functional space is generated by using the pictures. When a user needs to learn about the structure of the house, the user can view the virtual three-dimensional model created from the depth images; and when the user needs to learn about specific details of a functional space, the user can view the panoramic image of the functional space. The details of a functional space of the house can be displayed, and the structure of the house can be displayed as well, which helps the user to fully learn about the house.
