| Multiple sensors, information fusion technology and the combination of the traditional robot constitutes the intelligent robot. Intelligent robot is equivalent to the replication of human, and a variety of different sensor is constitutes the "features" of intelligent robots. Intelligent robot can respond to the change of the surrounding environment, requires intelligent robots have the ability to sense their surroundings, and the ability to use sensors to collect the information integrated processing and intelligence operations, this also is the embodiment of the intelligent robot.With the development of science and technology, multi-sensor fusion technology is also useful applications from the beginning, to the present civil, medical, financial, security and other fields. The development of multi-sensor information fusion technology, a single information already cannot satisfy people growing demand for information. In this paper the research of intelligent robot system, the single image information and the single voice information can not meet the requirement of the intelligent robot for family services, must according to certain algorithm will be two different types of sensor information fusion, play advantage of the two goals of recognition.By consideration of the design requirements, and the study of fusion algorithm is relatively mature, and finally confirmed by CCD camera, image processing module of DSP processing image information, voice processing module by LD3320 acquisition, FPGA processing voice information, according to the expert system and artificial neural network algorithm for the fusion of two modules.Defining the design of the hardware and software and the fusion algorithm, experimental verification to the system. First on intelligent robot audiovisual two modules respectively to validate system feasibility, through experimental verification, you can get two modules are comply with the design requirements. Finally after fusion experiments, validated both fusion algorithm can realize the target of correct identification.Intelligent robot not only can be used in the family environment, can also play a role in otther environments. Intelligent robot audio-visual integration system provides the mobility of the elderly and disabled, intelligent life has played a positive significance for the future. |
