sensorThe theory and application of information fusion technology involve multiple disciplines such as information electronics, computer science, and automation, and is a widely applied comprehensive high-tech.

1. In the field of information electronics

The implementation and development of information fusion technology are based on the principles, methods, and technologies of information electronics. The information fusion system needs to use multiple sensors to collect various information, including sound, light, electricity, motion, vision, touch, force perception, and language and text. For example, the "smart bomb" used in the Gulf War had a combination of laser and radar sensors. The distributed information processing structure in information fusion technology is achieved through wireless networks, wired networksintelligent network Communication networks such as broadband intelligent integrated digital networks are used to gather information and transmit it to the fusion center for fusion. In addition to natural (physical) information, information fusion technology also integrates social information, represented by language and writing, which involves large-scale Chinese language databases, language knowledge acquisition theories and methods. Machine translation, natural language understanding and processing technologies, and information fusion utilize mathematical and physical theories and methods such as fractal, chaos, fuzzy reasoning, and artificial neural networks. Its development direction is to integrate and correlate information of different properties of nonlinear and complex environmental factors, and observe and explore the world from various perspectives.

2. In the field of computer science

The development history of computers has evolved from serial computers to parallel computers, from numerical computing to image processing, and from general databases to comprehensive image databases. From the perspective of information fusion, future computers will inevitably include multiple functions such as numerical parallel computing, image processing, and comprehensive spatiotemporal image understanding. Gradually realizing a thinking mode similar to the human brain for information collection, processing, and comprehensive storage.

In computer science, research on parallel databases, active databases, and multi databases is currently underway. Information fusion requires systems to adapt to the changing external world, therefore, the concept of spatial and temporal databases has emerged, providing guarantees for data fusion. Space means that different types of data come from different spatial locations; Time implies that databases can adapt to changes in the objective environment over time.Information FusionThe processing requires corresponding database principles and structures to integrate data that has changed over time and space. Under the concept of information fusion, the spatial and temporal databases proposed are an important research direction in computer science.

3. In the field of automation

In the field of automation in information science, information fusion technology is based on various control theories. Information fusion technology adopts system theories such as fuzzy control, intelligent control, and evolutionary computing, and combines knowledge from fields such as biology, economics, society, and military to conduct qualitative and quantitative analysis. According to the functions and principles of the human brain, visual, auditory, tactile, sensory, perceptual, attention, memory, learning, and higher-level cognitive processes are carried out, integrating spatial and temporal information, automatically interpreting data and information, and making judgments on the environment and situation. The current control technology has evolved from program control to information fusion based controlintelligent control. For example, the Patriot missile system in the Gulf War defeated the program controlled ScudMissile. Intelligent control systems are not only used for military purposes, but also for production process control and supply and marketing management in factories and enterprises, urban construction planning, road traffic management, commercial management, financial management and forecasting, geological and mineral resource management, environmental monitoring and protection, monitoring of grain crop growth, disaster weather forecasting and prevention, and other industries involving macro, micro, and social aspects. The best embodiment of the idea of information fusion is in the research of intelligent robots. Research and exploration of biomimetic mechanisms for intelligent robots,

The three-dimensional and time-varying image processing in robot vision, active vision research, acquisition and understanding of non visual sensor information inside and outside robots, behavior control of intelligent robots, environmental modeling and processing, knowledge cognition and logical reasoning, as well as the application of neural and network technology in robot control and sensor information processing, are all related toInformation FusionThe technology of information fusion, which is related to ideas, will develop rapidly.
