Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] The application of the AR technology of the present invention realizes the transformation from the three-dimensional virtual world to the three-dimensional augmented reality world, and the visual display of the components hidden inside the wall is more perceptual, so that the building information can be displayed more comprehensively, intelligently and intuitively. Giving full play to the advantages of building information model and AR technology can significantly improve the spatial positioning accuracy and efficiency of hidden pipelines on the project site, with a high degree of intelligence and low cost, and realize the position control of the construction of hidden pipelines in the project. Provides a basis for decision-making guidance. The application of technologies such as model size measurement, two-dimensional code calibration of engineering m...

Abstract

The invention discloses a project hidden pipeline measurement and spatial position automatic matching method based on BIM+AR. The method comprises the steps that firstly combinative application is carried out on BIM technology and AR, calibration of two-dimensional code models in a BIM model provides data support for taking the BIM model, two-dimensional code pasting and information extraction technology corresponding to project site provide conditions for AR technology display visualization models being applied, and model distance measuring results, model and live-action measurement and hidden pipeline spatial position matching technology provide the basis for hidden pipeline spatial position positioning. According to the project hidden pipeline measurement and spatial position automaticmatching method based on the BIM+AR, the changing from the three-dimensional virtual world to the three-dimensional augmented reality world is realized applied by the AR technology, visual presentation is carried out on components hidden in wall bodies, the perceptibility is higher so that building information can be presented more comprehensively, more intelligently and more intuitively, the advantages of building information models and the AR technology can be brought into full play, and accuracy and efficiency of the spatial positioning of the project site hidden pipeline can be significantly improved.

Description

technical field [0001] The invention belongs to the expanded application technology of AR in the field of construction engineering, in particular to a BIM+AR-based engineering concealed pipeline measurement and spatial position automatic matching method. Background technique [0002] Augmented Reality (AR for short) is a technology that calculates the position and angle of the camera in real time and adds corresponding images. The goal of this technology is to put the virtual world on the screen and interact with the real world. This technology was first proposed in 1990. With the improvement of computing power of mobile electronic products, augmented reality has become more and more widely used. Our country has paid attention to the research and application of virtual reality technology in the past ten years. Due to the limitation of technology and cost, the main application objects are military and high-end commercial use. The products suitable for ordinary consumers have ...
