Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] The invention discloses an augmented reality stakeout system based on BIM technology, which uses the augmented reality technology to carry out simulated stakeout of the designed BIM model on the construction site, so as to clarify the corresponding mapping relationship between each design position in the BIM model and the construction site , which can avoid the on-site construction personnel from misunderstanding the design intent expressed by the BIM model, and it is more convenient for Party A and the supervisory unit to supervise the construction site.

[0042] like figure 1 As shown, the augmented reality stakeout system includes a positioning device 1 and an augmented reality device 3 worn by a user 2. The positioning device 1 is used to track the position of the augmented reality device 3 to realize the stakeout operation of the BIM model ...

Abstract

The invention discloses an augmented reality lofting system and method based on a BIM technology. The method comprises the steps that a construction site is located in a positioning and tracking rangeof a positioning device, and a standard ruler is used for measuring and positioning the working space of the positioning device and establishing a measurement coordinate system; coordinates of key design positions A / B / C in the measurement coordinate system are determined respectively; coordinate transformation parameters of a construction design coordinate system which is converted to the measurement coordinate system are determined; the coordinate conversion parameters are utilized to conduct coordinate transformation on a BIM model, then the BIM model after subjected to coordinate transformation is loaded into augmented reality equipment, and when a user wears the augmented reality equipment on the head to observe the construction site, the BIM model is displayed in the construction site and all the key design positions of the BIM model overlap with all key construction positions of the construction site one to one respectively. By means of the method, the mapping relationship of the construction site and the BIM model can be accurately determined so that a BIM three-dimensional design result of a design unit can be accurately superimposed on the construction site by using an augmented reality technology.

Description

technical field [0001] The invention relates to building information processing technology, in particular to an augmented reality lofting system and an implementation method based on BIM technology. Background technique [0002] Augmented Reality (AR for short) is a technology that calculates the position and attitude of camera images in real time and adds corresponding images. The goal of this technology is to superimpose the virtual world on the screen and interact with the real world. In order to achieve the perfect combination of virtual and real scenes in the augmented reality system, the virtual added information generated by the computer needs to maintain a precise alignment relationship with the real scene through a three-dimensional tracking registration algorithm. [0003] In augmented reality system, tracking and registration is the basic technology of augmented reality system construction, and also the key to determine the performance of augmented reality system....
