Description

Technical Field

[0001] The present invention relates to the fields of blockchain, virtual scenes and computer technology, and in particular to a virtual scene application system based on blockchain. Background Art

[0002] The blockchain has become a national strategy and has greatly promoted the rapid development of the blockchain industry. The Internet of Things group is an important cornerstone of the blockchain, and the numerous sensor networks at the end of the Internet of Things are the foundation of the Internet of Things. 5G is the main direction of the development of the new generation of mobile communication technology and an important part of the future new generation of information infrastructure. Compared with 4G, 5G has the technical characteristics of "ultra-high speed, ultra-low latency, and ultra-large connection". It will not only further enhance the user's network experience and bring faster transmission speeds to mobile terminals, but also meet the application needs of the future Internet of Everything, giving everything the ability to connect online, but also provide support for the realization of large-volume Internet of Things based on audio, video, and vision.

[0003] The Video Sensor Network is a distributed sensing Internet of Things composed of a group of video sensor nodes with computing, storage and communication capabilities. It uses the video sensors on the nodes to perceive the image and video information of the surrounding environment, and transmits the data to the information aggregation node through multi-hop relay. The aggregation node analyzes the monitoring data to achieve comprehensive and effective environmental monitoring.

[0004] At present, most of the domestic virtual scene implementations are based on virtual reality (VR) technology, virtual reality enhancement technology and geometric modeling technology. Virtual reality (VR) technology and virtual reality enhancement technology are mostly implemented in the form of stand-alone systems. However, the virtual scene implemented by geometric modeling technology cannot produce the actual scene feeling, is subject to great scene constraints in actual applications, and the experience is not good. The industry is in urgent need of a virtual scene application system that can meet actual applications. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a virtual scene application system based on blockchain to solve the problems existing in the prior art.

[0006] To achieve the above-mentioned purpose and other related purposes, the present invention provides a virtual scene application system based on blockchain, comprising: a blockchain data extraction module, a material database module, a model generator, a scene restoration data output module, a result database and a visualization module;

[0007] The blockchain data extraction module is located at the bottom layer of the system and is used for time series two-dimensional scene image data processing, converting the input data format into a row vector form of timestamp and image data;

[0008] The material database module is located in the upper layer of the blockchain data extraction module, and is used to store the sampled data formatted by the data preprocessing module in ascending time order;

[0009] The model generator calculates the three-dimensional scene model parameters according to the output of the material database module, and is connected to the material database module and the scene restoration data output module;

[0010] The scene restoration data output module is connected to the output of the model generator and is used to cache and format the scene restoration matrix output by the model generator;

[0011] The result database is connected to the scene restoration data output module and is used to continuously store the output result sequence of the scene restoration data output module;

[0012] The visualization module is connected to the result database and is used to dynamically display the result sequence stored in the result database.

[0013] Optionally, the time series two-dimensional scene images collected by the blockchain data extraction module are collected at equal time intervals, indicating that the CMOS sensor lens at the end of the blockchain moves a fixed distance.

[0014] Optionally, the material database module adds a displacement mark when formatting the sampled data.

[0015] Optionally, the model generator uses image-based modeling and rendering (IBMR) technology to restore the real three-dimensional world scene according to two-dimensional continuous pictures.

[0016] Optionally, the result database is a text file in text form, a SQL SERVER database, an ORACLE database or a MYSQL database.

[0017] Optionally, the visualization module draws and restores the scene based on openGL library and openCV library.

[0018] As described above, the present invention provides a virtual scene application system based on blockchain, which has the following beneficial effects: the present invention integrates 5G technology, blockchain Internet of Things technology and visual sensor technology, applies IBMR technology to restore real three-dimensional virtual scenes from two-dimensional scene pictures, overcomes the bottleneck of virtual reality (VR) technology application scenarios, and overcomes the problem that virtual scenes realized by geometric modeling technology cannot produce actual scene perception. In fact, the blockchain terminal CMOS sensor network has covered most areas of the country, which provides necessary conditions for the realization of virtual scene application systems based on blockchain, and also reduces the construction cost of virtual scene application systems.
