Abstract: Sometimes，in the airplane images，the object pixels have a clear distinction to those of the background.But the position，angle and scale of the object change actively.It troubles the airplane image object recognition.The paper proposes a recognition method based on the moments and corner characters of the object.Firstly，segments the objects in the template image and the image to be measured.The segmentation results would be standard by the moment characters.Then calculats the comparability between the two objects though the edge points of the template image object and the corners of the object in the image to be measured.The experiments show that the proposed method is an efficiency algorithm and has good adaptability.

Key words: moment, corner, object recognition, comparability
