Embodiment Construction

[0021] Example figure 1 and figure 2 As shown, the present invention uses mixed reality technology to realize the positioning method between the building model and the entity, including the following steps:

[0022] Step 1. Based on various relevant information data of the physical building, a building BIM model of the physical building is established through digital information simulation, and the physical building and the building BIM model adopt the same coordinate system;

[0023] Step 2. Paste the QR code 2 at any position on the wall 1 of the physical building. The QR code 2 contains the coordinate information of the pasted position and the angle information between the pasted wall and the magnetic north direction, and also contains a Y-axis direction identification Parameter information;

[0024] Step 3. Set the head-mounted display device 4 of mixed reality technology on the position of the building BIM model. The head-mounted display device 4 includes a depth camer...

Abstract

The invention discloses a method for realizing positioning between a building model and an entity by using the mixed reality technology. The method comprises a step of establishes a building BIM modelof a physical building and adopting the same coordinate system, pasting a two-dimensional code at any position of a physical building wall, wherein the two-dimensional code includes the coordinate information of a position of pasting the two-dimensional code, the information of an angle with a north magnetic pole direction and Y-axis direction identification parameter information, and a step of setting a head-mounted display device at the position of the building BIM model, allowing a depth camera to the head-mounted display device to scan the two-dimensional code to read relevant information, the distance between a sensor measuring device and the two-dimensional code, the angle between an electronic compass measuring device and the north magnetic pole direction and the angle between a gravity sensor measuring device and a gravity direction, obtaining the coordinates of the device in the coordinate system through calculation, and determining the coordinates of the building BIM model relative to the physical building. According to the method, the positioning between the building BIM model and the entity is achieved through a mixed reality device, and location information is provided for the display of the building BIM model.

Description

technical field [0001] The invention relates to a positioning method between a building model and an entity by applying mixed reality technology. Background technique [0002] Mixed reality technology is still in the stage of perfection, and the application of mixed reality technology to display architectural BIM models is still in the exploratory stage. The building BIM (Building Information Modeling) model is based on the relevant information data of the construction project, establishes a three-dimensional building model, and simulates the real information of the building through digital information simulation, which has information completeness and information relevance. , information consistency, visualization, coordination, simulation, optimization and plotting. The architectural BIM model enables engineering and technical personnel to correctly understand and efficiently respond to various architectural information, and provides a basis for collaborative work for the...
