Embodiment 1

[0084] In order to further describe the method of the embodiment of the present invention, the Mars probe is taken as an example to explain the specific process of the embodiment of the present invention in detail:

[0085]Since the Mars probe is deployed on a planet in space, humans cannot set foot in it at present, so there is a problem that it is impossible to intuitively understand the topography of Mars. Using the method of the embodiment of the present invention, it is possible to visually present the topography of Mars in the environmental space where humans live, and at the same time Part of the actual object or environment (such as a real probe built one-to-one) can be accurately matched with the virtual Martian landform, allowing operators to achieve a real on-the-spot experience.

[0086] Step 1: Before the launch of the Mars rover, select a fixed position on it as the GCS coordinate system (the center of the Mars rover arm turntable is selected as the origin of the ...

Abstract

The invention provides a remote virtual-real high-precision matching and positioning method for augmented reality and mixed reality, and relates to the technical field of mixed reality and augmented reality. By constructing multiple coordinate systems and determining the position relation between the coordinate systems, the real markers are used for determining the positions of the point cloud scene of the remote scene and the near-end virtual scene in the near-end environment space, and oriented remote virtual-real high-precision matching positioning is achieved. Method according to the invention, according to the method, the position of the virtual object in the mixed and augmented reality environment can be adaptively and accurately positioned on the basis of marking the position of theobject in the real space and crossing the space obstacle, and the scene in the virtual space is accurately superposed into the near-end environment space, so that interactive operations such as remote training demonstration and auxiliary guidance under virtual-real comparison are conveniently realized.

Description

technical field [0001] The invention relates to the technical field of mixed reality and augmented reality, in particular to a method for remote virtual-real high-precision matching and positioning for augmented and mixed reality. Background technique [0002] Augmented and mixed reality technology seamlessly superimposes computer-simulated digital information data with real scene environments, breaks through space and time constraints, and realizes highly immersive, real-time information guidance and virtual-real interaction without a sense of separation. Its essence is reflected in "what you see is what you get, what you touch is what you see". With the help of this technology, the information displayed and interacted on the screen can be replaced with three-dimensional information strongly related to the actual environmental objects, which can be intuitively presented to the user. [0003] An important application scenario of augmented and mixed reality is remote assiste...
