The invention discloses a cooperative obstacle dodging method and a device thereof. The method comprises the steps of when an obstacle is detected in a flight advancing direction, acquiring position of the obstacle and contour of the obstacle, uniformly distributing a plurality of point sources along the contour of the obstacle, thereby forming a uniform potential field, constructing a potential function of the uniform potential field so that a constructed obstacle expulsive force potential function accords with the outer surface of the obstacle, and transmitting an obstacle dodging control instruction according to the position of the obstacle and the potential function. Because the plurality of point sources distributed on the outer surface of the obstacle generate the expulsive potentialfield which accords with the contour of the obstacle, after the expulsive force potential function which is same with the contour of the obstacle is constructed, the obstacle dodging control instruction is transmitted according to the distance to the obstacle and the expulsive force potential function, an unmanned aerial vehicle set can be made to smoothly dodge the obstacle with random shape andrandom size in a short distance. The cooperative obstacle dodging method and the device thereof improve applicability of the cooperative obstacle dodging method.
