Physical image information fusion device and method

Abstract

The invention provides a physical image information fusion device and a physical image information fusion method. The method comprises the following steps of: rapidly and accurately obtaining left and right viewpoint positions of a model space through characteristic edges of a real space characteristic cube, and generating left and right images of the model space; completely coinciding the characteristic cube in the left and right images of the model space and the real left and right image characteristic cube to realize rapid fusion of the physical image information; and judging whether the viewpoint is changed by detecting whether the current real image is coincided with the characteristic points of the characteristic cube in the previous real image, and calculating a new viewpoint coordinate so as to generate a new model left and right image when the viewpoint is changed. The three-dimensional simulation of an assembly environment is realized based on a three-dimensional display mode, so that an operator has a feeling of being personally on the scene, the position of a real assembling unit is sensed through binocular vision, a virtual assembling unit model is established, the virtual assembling unit and the real assembling unit are fused, and the information world and the physical world are combined.

Description

technical field [0001] The invention relates to the field of 3D display technology of CPS (Cyber-Physical Systems) and image processing technology, specifically a cyber-physical image fusion device and method, which realize multi-angle fusion display of three-dimensional models and real objects. Background technique [0002] Cyber-Physical Systems (CPS) is a new type of embedded system that realizes the deep integration of the information world and the physical world through the mutual cooperation of computing, communication, control and other related technologies. CPS can adjust and control each physical entity in real time and efficiently according to the information of each feature point in the physical environment, which promotes the development of virtual assembly technology. [0003] It is an important process of virtual assembly to establish a virtual assembly environment that is consistent with the actual assembly production environment, and to carry out product asse...

AI Technical Summary

Problems solved by technology

[0005] 1) The assembly process of parts is usually affected by assembly tools, combined fixtures and other assembly environment information, but the current assembly environment construction technology only involves the 3D model construction process of parts, and does not take into account other assembly tools such as assembly tools and combined fixtures. environmental impact;

[0006] 2) At present, the interactive technology involved in virtual assembly completely relies on sensors and dialog menus to realize the simulation process of assembly, and has not realized the integration of the information world and the physical world

At the same time, the assembly simulation in the two-dimensional plane environment ignores the human-computer interaction process, and it is difficult to realize the real three-dimensional virtual assembly process
