Problems solved by technology

[0003] The existing method does not have the function of spatial positioning, so markers need to be pasted on the ground for identification and tracking. For example, if a developer develops a new community and wants to preview the real scene of the community, at this time, 50,000 people in this community are required. Put a sign in the center of the open space of square meters, and then walk for 30 minutes to scan the real scene in the planned preview area, and then superimpose the virtual model and the scanned real scene to preview the real estate, which leads to complex operation and intelligent level Low

Embodiment Construction

[0059] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0060] In order to solve the problem in the prior art that the global context information cannot be effectively used and the accuracy of organ segmentation is low due to the inconsistency between the multi-phase image data and the inability to effectively fuse the multi-phase image data.

[0061] The application provides a method for superimposing a virtual model and a real sce...

Abstract

The invention discloses a method and a device for realizing superposition of a virtual model and a real scene based on orientation. According to the method, the technical means of ARkit and geographic positioning are comprehensively used in a Unity 3d engine, and geographic coordinates serve as reference of the placement position of a virtual model, so that the virtual model combined with a real scene has a spatial orientation memory function. Therefore, according to the method, the virtual model can be laid on the real scene ground according to the geographic coordinates, namely the virtual model is placed in the real scene without pasting a marker on the ground and carrying out real scene scanning. The device is convenient to operate and high in intelligent degree, and enables the urban construction space combined with the real scene to be visualized. The invention further provides a conversion method for the geographic coordinates and the world coordinates of the virtual reality software, so that the position where the virtual model and the real scene are overlapped is closer to a preset position, and errors can be reduced.

Description

technical field [0001] The present application relates to the field of virtual reality technology, and in particular to a method and device for realizing orientation-based superimposition of a virtual model and a real scene. Background technique [0002] Currently, it is necessary to superimpose the virtual model with the real scene when previewing the real scene of the building. [0003] The existing method does not have the function of spatial positioning, so markers need to be pasted on the ground for identification and tracking. For example, if a developer develops a new community and wants to preview the real scene of the community, at this time, 50,000 people in this community are required. Put a sign in the center of the open space of square meters, and then walk for 30 minutes to scan the real scene in the planned preview area, and then superimpose the virtual model and the scanned real scene to preview the real estate, which leads to complex operation and intelligen...
