Abstract

The invention discloses an intelligent space and nurse robot multi-sensor system, establishes a manual sign expression model of the typical QRCode and RFID (radio frequency identification devices) based technique in intelligent space, builds a multi-mode information expression system based on improved JDL (joint directors of laboratories) model and a multi-mode information acquiring model based on a distribution type data fusion tree, and designs a corresponding fusion algorithm by aiming at the characteristics of each layer. The model shields the isomerism of the device and the complexity of environment. By considering the dynamics, isomerism and hierarchy of intelligent space information and organically combining local fusion with overall fusion, the fusion efficiency is increased, the fusion precision is ensured, the recognition of intelligent space to human and environment is improved, the system is conveniently integrated, and the expandability and the reusability of the system are improved.

Description

technical field [0001] The invention relates to an intelligent space and nurse robot multi-sensor system and an information fusion method thereof. Background technique [0002] There are a large number of distributed sensors in the smart space, which provide rich heterogeneous information for the smart space. In order to make full use of the ubiquitous services and resources in the smart space, it is necessary to establish a corresponding information model representation method. This model enables the intelligent space and service robot system to have multi-mode information acquisition capabilities, and realize richer information services and sharing. In the traditional mode, the relationship between service robots and sensing devices is one-to-one and direct possession, and the robot and computing environment are fixed. This mode limits the communication and sharing of information, and it is difficult to meet the needs of smart spaces. [0003] The information service of ...

Problems solved by technology

A complete information fusion system includes many aspects such as the functional model of information fusion, fusion level, fusion topology, and appropriate fusion methods. The current research on this topic mainly focuses on different fusion algorithms and their improvements. Designing a reasonable information fusion model for the smart space, selecting an efficient information fusion algorithm and system learning algorithm, and providing a multi-mode information acquisition mechanism for the smart space are still seldom studied
