Abstract

The embodiment of the invention provides a real-time three-dimensional reconstruction system and method for a solid building block model based on distributed sensing. The system comprises: a distributed sensing subsystem and a three-dimensional reconstruction subsystem. Identification information of all the entity building blocks and connection information between the entity building blocks and the entity building blocks on the lower portion of the entity building blocks are obtained through the distributed sensing subsystem, and construction of a three-dimensional splicing model of the entitybuilding blocks and the entity building blocks on the lower portion of the entity building blocks is achieved through the three-dimensional reconstruction subsystem. According to the invention, the active and distributed sensing subsystems are introduced, the characteristics of light weight and expandability are maintained while the recognition precision is effectively improved, and the robustness of the whole system can be improved. According to the embodiment of the invention, based on the detection of the topological relation between the connected entity building blocks and the lower entity building blocks, the problems of shielding, recognition and the like encountered by a computer vision method 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
