This paper proposes a distributed multi-sensor information fusion structure without fusion center, and the corresponding fusion algorithm. Based on the fusion structure, each sensor sends the acquired target’s information to its out-neighbors, at the same time, associates and fuses the information from its in-neighbors, and then sends the fused message to its out-neighbors. Through such a cyclic process, a decentralized multi-sensor fusion structure is thus constructed in the way of the multi-point parallel fusion. By means of opinion dynamics, a distributed discrete-time fusion algorithm is then designed. It is proven that all sensors can realize the consensus fusion in a short time by the new distributed fusion scheme if the multi-sensor network is strongly connected or has a directed spanning tree, even though there are the “blind” sensors in the sensor system. Finally, the experimental simulations are illustrated to verify the effectiveness of the proposed fusion scheme and algorithm.
