Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with specific embodiments.

[0020] A specific embodiment of the construction management method based on HoloLens-based BIM+MR of the present invention:

[0021] The construction management method of BIM+MR based on HoloLens includes the following steps:

[0022] Step 1: According to the project construction drawings, use Revit software to construct BIM model and information;

[0023] Step 2: Through the BIM-MR plug-in on the Revit side, convert the BIM model built by the Revit software into a model format that can be recognized by Unity, and at the same time extract and retain the model information. The BIM-MR plug-in on the Revit side needs to optimize the number of model faces to achieve Requirements that the HoloLens device can carry;

[0024] Step 3: Establish a BIM-MR communication and data server, and connect the Revit software on the user's PC side and the HoloLens device side to ob...

Abstract

The invention relates to a construction management method of BIM + MR based on HoloLens, and the method comprises the steps: 1, building a BIM model and information through employing Revit software according to a project construction drawing; 2, a BIM model constructed by Revit software is converted into a model format capable of being recognized by Unity through a BIM-MR plug-in at the Revit end, meanwhile, model information is extracted and reserved, and the BIM-MR plug-in at the Revit end needs to optimize the model surface number so as to meet the requirement that HoloLens equipment can bear the model surface number; step 3, establishing a BIM-MR collaborative network server, and connecting Revit software of a user PC terminal and a HoloLens device terminal so as to acquire the acquired BIM data in real time, and synchronously displaying the acquired BIM data in an MR scene of HoloLens; 4, construction is carried out based on the BIM-MR function of the HoloLens client, and positioning correspondence is carried out on the BIM model and a real coordinate system through a model positioning function; and 5, carrying out construction quality acceptance and operation and maintenance based on the BIM-MR function of the HoloLens client. The BIM information data can be better matched with the on-site entity construction part, rework is reduced, material waste is avoided, cost is saved, and construction efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of building construction, in particular to a HoloLens-based BIM+MR construction management method. Background technique [0002] BIM (Building information modeling, building information modeling) is based on the relevant information data of the project as the basis of the model, to establish the building model, and to simulate the real information of the building through digital information simulation. The BIM model has complete data, and its eight characteristics are intuition, relevance, consistency, visualization, easy coordination, easy simulation, easy optimization, and mapability of information. By sharing a unified architectural model, project participants such as construction units, design units, construction units, and supervision units can share data and information on the same platform, and collaborate to improve the construction process. Compared with traditional construction processes, i...
