An active structure (also known as a smart or adaptive structure) is a mechanical structure with the ability to alter its configuration, form or properties in response to changes in the environment. The term active structure also refers to structures that, unlike traditional engineering structures (e.g., bridges, buildings), require constant motion and hence power input to remain stable. The advantage of active structures is that they can be far more massive than a traditional static structure: an example would be a space fountain, a building that reaches into orbit.
A method, device and storage medium for three-dimensional modeling of a housing source
The application provides a house source three-dimensional modeling method, equipment and a storage medium, wherein the method comprises using a camera to shoot a first video of the interior of a house, and splitting the first video into multiple indoor images. The indoor image set is subjected to semantic segmentation, and movable obstacles in the indoor image set are removed according to K labels. The active structure in the house interior structure image set is marked according to the K labels, and the two sides of the active structure are subjected to connected component analysis. The house interior structure image set is converted into M three-dimensional point clouds, and the M three-dimensional point clouds are reconstructed based on the spatial connection relationship. N reconstructed point clouds are subjected to Poisson reconstruction, and the interior three-dimensional model of the house source is obtained. The application adopts the semantic segmentation mode to exclude the influence of furniture and other movable obstacles on the house structure, uses the active structure to improve the accuracy of the spatial relationship between different regions in modeling, and represents the space separated by the active structure, so that the house is comprehensively and accurately three-dimensionally modeled.
