Based on the detecting corner information of the tower image, according to the feature of the front-view tower image satisfying the left-right symmetry of the building area approximately, an algorithm calculating the medial axis of the tower area is proposed. On the basis of the morphology feature of the tower and knowing the medial axis, the corresponding algorithm is presented to locate the tower peak and the left-right tower corners. Finally, according to the three key points, demarcating the tower building area is realized.
