Intelligent space and nurse robot multi-sensor system and information fusion method of intelligent space and nurse robot multi-sensor system

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.
