Example Embodiment

[0013] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention. Detailed implementation modes and specific operation procedures are given, but the protection scope of the present invention is not limited to the following Mentioned examples.

[0014] According to the method for matching mobile augmented reality virtual coordinates and construction site coordinates according to the present invention, the engineering mobile augmented reality application system is developed by using the mobile augmented reality interface such as Arkit after importing the engineering 3D design model into the 3D engine such as Scenekit figure 2 As shown, that is: when the mobile terminal device automatically establishes a virtual coordinate system when the application is started, the virtual coordinate system takes the position of the camera of...

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...
