Abstract: Compared with DST，DSmT can keep the conflict of evidences as a focus element in data fusion in order to resolve the difficulty in the high conflict.But the DSmT’s computation will oversize more easily because more focus elements are additional in DSmT rule.And the fusion result is worse than DST’s when the low conflict situation is occurred.Aiming at it，this paper proposes one kind of intelligent algorithms on basis of DST and DSmT，combining their advantages.The algorithm uses conflict mass as a judgment in conflict evidences.DST fusion rule is adopted when conflict mass is lower.And DSmT fusion rule is adopted while opposition.It reduces computation with same fusion quantity.At last，Pioneer II mobile robot is used and the correctness and validity of the developed method are verified.
