Problems solved by technology
Because the information expression of two-dimensional design drawings is not direct, it causes certain difficulties in the communication and understanding among equipment designers, engineers and manufacturers. Therefore, the 3D virtual display of 2D drawings based on augmented reality technology has attracted more and more attention. Now Some implementations of 2D and 3D mixed augmented reality have a large amount of calculation and the recognition rate is not high

Embodiment Construction
[0053]The present invention provides a method and system for realizing 2D and 3D mixed augmented reality based on mobile devices, which are applied in the technical field of 2D / 3D mixed augmented reality. The method for realizing 2D and 3D mixed augmented reality based on mobile devices in the present invention includes: 2D drawing management server management and configuration; 2D drawing recognition device recognizes 2D drawings; 2D / 3D data hybrid visualization device realizes 2D / 3D data hybrid visualization based on mobile devices; implementation method of 2D and 3D hybrid augmented reality based on mobile devices in the present invention Recognition of design drawings through mobile device video without marking the drawings, and in order to identify design drawings, extract boundary points from the video image to determine the 2D drawing area, because the feature points in the entire image are displayed according to the 2D drawing area The amount of calculation is much smal...

The invention discloses a method and system for achieving 2D and 3D hybrid augmented reality based on mobile equipment, and the system comprises a 2D drawing management server which is used for management and configuration; a 2D drawing recognition device for recognizing a 2D drawing; a 2D / 3D data mixing visualized device which is used for achieving the 2D / 3D data mixing visualization based on mobile equipment. The system provided by the invention, carries out the recognition of a design drawing through the mobile equipment, does not need to mark the drawing, and extracts boundary points for determining a 2D drawing region from a video image so as to recognize the design drawing. Because the feature points of the whole image are extracted according to the displaying degree matching of the 2D drawing region, the calculation burden is far less than the calculation burden of a conventional matching mode, and the recognition rate is greatly improved.
Description
technical field [0001] The invention relates to the technical field of 2D / 3D mixed augmented reality, in particular to a method and system for realizing 2D and 3D mixed augmented reality based on mobile equipment. Background technique [0002] Augmented reality is widely used in various industries including power equipment manufacturing because of its ability to enhance the sense of reality immersion. Because the information expression of two-dimensional design drawings is not direct, it causes certain difficulties in the communication and understanding among equipment designers, engineers and manufacturers. Therefore, the 3D virtual display of 2D drawings based on augmented reality technology has attracted more and more attention. Now Some implementations of 2D and 3D mixed augmented reality have a large amount of calculation and a low recognition rate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method a...
