Abstract

The embodiment of the present invention provides a system and method for real-time three-dimensional reconstruction of a solid volume model based on distributed sensing. The system includes: a distributed sensing subsystem and a three-dimensional reconstruction subsystem. The identification information of the building block and the connection information between the solid building block and its lower solid building block are obtained, and the three-dimensional splicing model of the solid building block and the lower solid building block is realized through the three-dimensional reconstruction subsystem. The real-time three-dimensional reconstruction system of solid building blocks based on distributed sensing provided in the embodiment of the present invention introduces an active and distributed sensing subsystem to effectively improve the recognition accuracy while maintaining the characteristics of light weight and expandability , and can improve the robustness of the whole system. In the embodiment of the present invention, based on the detection of the topological relationship between the connected solid blocks and the lower solid blocks, problems such as occlusion and recognition encountered by computer vision methods can be solved in principle.

Description

technical field [0001] The present invention relates to the technical field of computer-aided design, more specifically, to a system and method for real-time three-dimensional reconstruction of a solid block model based on distributed sensing. Background technique [0002] With the development of digital technology, digital 3D models are increasingly used in various scenes and fields, such as mechanical design, architectural design, entertainment design and so on. However, 3D modeling is still a highly professional job, and it is difficult for novice users to learn the design of 3D models in a short time, which also hinders the possibility of rapid prototyping for users according to their own needs. In the field of computer-aided design, how to provide a convenient tool for users to build digital models has been a research hotspot all the time. [0003] Solid building blocks are a common tool used for children's education and creative design, with features such as ease of u...

Problems solved by technology

[0005] However, both 3D reconstruction using computer vision technology and 3D reconstruction using capacitance measurement technology are passive detection technologies. When 3D reconstruction using computer vision technology is used, its feasibility is limited by the installation position of the camera and image quality. and other factors, the reconstruction effect will also be affected by factors such as light and occlusion, and the recognition stability is low

When using capacitance measurement technology for 3D reconstruction, it will also face many external environmental influences, such as human touch or interference from other conductors will lead to recognition errors
