Abstract: According to the target with no significant visual features，a novel vision navigation method is proposed.In the vision heading navigation，the salient feature point with known relative position to the target is chosen as the reference point.And the pose adjustment quantities of the robot are determined according to the image of the reference point.To improve the environmental adaptability，this algorithm uses only one reference point and has the advantages of simple structure and low computation complexity.Experimental results show that the vision navigation method combined with the location navigation device can eliminate the pose errors effectively，and the applicability and stability of the method are verified.
