Embodiment Construction

[0028] Hereinafter, specific aspects of the present invention will be described with reference to the drawings, but the present invention is not limited to the examples shown in the drawings.

[0029] Such as figure 1 As shown, the present invention superimposes the processed input video stream on the surface of the corresponding plain model sand table through a projector, so as to realize real-time simulation and miniature reproduction of the dynamic changes of the real scene. The projector can be installed vertically and project downward, or it can be installed horizontally as shown in the figure and use a reflector to project the projected content onto the plain sand table from top to bottom. The final effect is as follows figure 2 as shown, figure 2 (b) in represents the original white plain model sand table without texture, after the fusion processing of the input video stream, the figure 2 The real scene shown in (a) in (a) is vividly reproduced, and the authentic...

Abstract

The invention discloses a mixed-reality sandbox device and method. The sandbox device is formed by a prime module sandbox, a projector and a computer. The input is from a plurality of monitoring cameras in the real world, which collect local scenes of the real world and provide input video streams for the device; the prime module sandbox of the device is made according to the real world in a certain scale; the surfaces of regions corresponding to the input video streams are light-color diffuse reflection materials; and the projector is arranged above the prime module sandbox, and projects downwards onto the surface of the sandbox. The method adopts a two-step alignment strategy to calibrate the input video streams, then, carries out splicing on overlap regions through an edge-adaptive image fusion algorithm, and enables images and videos in the real scene to be fused and projected to the surface of the prime module sandbox in real time in the device operation process according to the obtained calibration result, thereby realizing real-time simulation and miniature reproduction of dynamic change of the real scene.

Description

technical field [0001] The invention relates to a mixed reality sand table device and method, which mix real scenes with physical models in real time, and belong to the technical field of virtual reality. Background technique [0002] In recent years, virtual reality technology (VR) has developed rapidly, and mixed reality technology (MR), one of its branches, mixes the real world and the virtual world, so that it can show more details of the real world and provide more realistic presentations. Effect. Spatial Augmented Reality (SAR), as an important branch of mixed reality technology, can use projectors, transparent screens and other equipment to enhance the surface of real objects. This technology provides spatial information of physical existence and allows multiple people to simultaneously Enhance interaction in space. [0003] A lot of space augmented reality research has been carried out internationally. As early as 1998, Raskar et al. put forward the idea of ​​futur...
