Interactive demonstration method and system for BIM augmented reality in building sand table

Abstract

The present invention discloses an interactive demonstration method and a system for the BIM augmented reality in a building sand table. The method comprises the steps of establishing a terrain three-dimensional model on an elevation digital model, establishing a sand table building three-dimensional model on the BIM and storing the established model inside a database server; acquiring the range of characteristics on a medium by a camera shooting device, acquiring the terrain three-dimensional model and the sand table building three-dimensional model of the corresponding number out of the range of characteristics to generate a sand table three-dimensional model by an AR client; outputting the sand table three-dimensional model to a display device and realizing the superimposed display of the sand table three-dimensional model within the corresponding range of characteristics of display equipment; acquiring the corresponding gesture action of an operator by somatosensory equipment; acquiring the terrain three-dimensional model or the sand table building three-dimensional model of the corresponding number by the AR client according to the gesture action of the operator, and outputting the acquired terrain three-dimensional model or the sand table building three-dimensional model of the corresponding number to the corresponding range of characteristics of the display equipment. In this way, the superimposed display of the terrain three-dimensional model or the sand table building three-dimensional model is realized. According to the technical scheme of the invention, the automatic identification and the automatic query of the AR client are realized. Meanwhile, the working efficiency and the working quality are greatly improved.

Description

technical field [0001] The invention relates to the application field of building planning approval, in particular to a BIM augmented reality interactive demonstration method and system in a building sand table. Background technique [0002] Existing traditional architectural planning generally uses a large amount of paper media for design, storage takes up space, production, printing, storage, maintenance, and retrieval are slow; regardless of pre-production, approval or post-storage, maintenance, and storage will bring additional resource consumption , For example, in the conventional planning approval process, paper atlases are usually used to review scheme comparison, green space, orientation, volume ratio, sunshine, energy saving, fire protection, etc. Data visualization cannot be performed, and traditional atlases are reviewed by a small number of people at the same time. The utilization rate of resources is low, and multiple people cannot review in parallel at the sam...
