Owing to the limits of a single sensor and uncertainties of sensor data

information fusion of multi-sensor system is frequently used to acquire a representation of environment and objects. In this paper

three main research topics of multi-sensor information fusion

i. e. representation of information

framework and means of fusion

and control off fusion

are discussed. Also

several typical results are introduced to describe the advances in those fields. Finally

our research strategies on multi-sensor information fusion are presented according to international research trends.
