Mobile augmented reality matching method for virtual coordinates and construction field coordinates

Abstract

The invention discloses a mobile augmented reality matching method for virtual coordinates and construction field coordinates. The method includes I, establishing an application system developed basedon an Arkit interface; II, pasting a two-dimensional code with pile point field coordinate information on two pile points in a construction field; III, placing a mobile terminal device exactly abovethe first pile point as an origin of coordinates and scans the two-dimensional code on the first pile point, acquires the field coordinates of a field coordinate system of the pile point, and acquiresthe virtual coordinates of the mobile terminal device in the virtual coordinate system synchronously, and modifying the position of the origin of coordinates of the virtual coordinate system; IV, through scanning the two-dimensional code on the second pile point, acquiring the field coordinates of the second pile point in the field coordinate system and the virtual coordinates of the mobile terminal device in the virtual coordinate system, and implementing the matching of virtual coordinates and field coordinates finally.

Description

technical field [0001] The invention relates to the application of mobile augmented reality technology in engineering, in particular to a method for matching virtual coordinates of mobile augmented reality with coordinates of a construction site. Background technique [0002] Augmented reality (English: Augmented Reality, referred to as AR) is a visualization technology that superimposes virtual text, images, and three-dimensional models in real scenes. With the improvement of the performance of mobile terminal equipment such as smartphones and Ipads (laptops, tablets), and the improvement of related spatial perception technologies, augmented reality technology has gradually moved from the PC terminal to the mobile terminal, from the two-dimensional enhancement of superimposed simple pictures and text Reality is moving towards the three-dimensional augmented reality that perceives the real three-dimensional space and can accurately place the three-dimensional virtual model i...

AI Technical Summary

Problems solved by technology

People try to apply mobile augmented reality technology to the construction site stakeout, but the problem is that the construction site often adopts a site coordinate system based on fixed pile points. The coordinate system takes the fixed pile point as the coordinate origin and the east-west direction as X Axis, the north-south direction is the Y axis, and the vertical direction is the Z axis
