A portable engineering BIM model projection device and method based on augmented reality

Abstract

The invention discloses a portable engineering BIM model projection device and method based on augmented reality, and relates to the technical field of augmented reality. The device comprises an imagecollector for obtaining a two-dimensional image, a central processor, and a memory, wherein the two-dimensional image comprises a paper two-dimensional engineering drawing or a two-dimensional code and is used for receiving the two-dimensional image pushed by the image collector, generating an image matching code according to the two-dimensional image, and pushing the image matching code to a background server through a network interface and the Internet; the background server stores the comparison drawings, and the comparison drawings and the image matching codes have a one-to-one corresponding mapping relation; the background server pushes the corresponding BIM model to a memory through the Internet and a network interface; the memory pushes the BIM model to the central processing unit;and the central processing unit pushes the BIM model to the micro projector. According to the present invention, the BIM building information model technology, the AR technology and the projection technology are combined, so that the problem of BIM model image sharing is solved.

Description

Technical field [0001] The present invention relates to the field of augmented reality technology, in particular to a portable engineering BIM model projection device and method based on augmented reality. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: BIM technology is the building information model, and the three-dimensional BIM technology can well show the relative position relationship of the engineering space; AR technology, the augmented reality technology, has the ability to compare the virtual world with the real world. The ability to combine. Through the combination of AR technology and BIM technology, BIM models can be displayed in conjunction with two-dimensional drawings, which will bring great convenience to the design, verification and review of engineering schemes. Currently, the commonly used technology to combine the two is to use portable augmented reality glasses Or a handheld device with a camera...

AI Technical Summary

Problems solved by technology

[0004] (1) Whether using augmented reality glasses or handheld devices with cameras, users cannot share the images they see with others;

[0005] (2) Due to the size limitation of portable augmented reality glasses or the screen of a handheld device with a camera, although the details can be viewed by zooming in on the model, the details and the overall view cannot be considered;

[0006] (3) Portable augmented reality glasses or handheld devices with cameras can be classified as wearable devices, which will occupy part of the user's limbs. For example, augmented reality glasses will occupy the user's eyes and make it difficult to distract and communicate with others. Occupying both hands of the user, it is difficult to balance when comparing BIM models, viewing 2D drawings, annotating on drawings, and discussing design plans with others

[0007] (4) The current market price of somatosensory devices is relatively high, and the volume is relatively large. Using somatosensory devices to realize gesture interaction will seriously affect product price competitiveness and product portability
