In order to avoid airplanes parking in the depot from crashing other moving airplanes

this paper proposed a method about position detection of airplane head based on image color character analysis. The method is used in the designing of intelligent security surveillance system for airplane depot toward the functioning of collision and striking warning. Firstly

the RGB image captured by the camera is transtormed into the HSI space. Then the red area

which is related to airplane head

is extracted by double thresholding of the saturation and hue components. And then the segmented image is post-processed with morphological operations to determine tile vertex of airplane head and the corresponding safe zone. Experimental results demonstrate that this method can detect the airplane head effictively and improve the performance of the classical surveillance system.
