Detection method of airport area through aerial shooting image

The invention discloses a detection method of an airport area through an aerial shooting image, and aims at solving the technical problem that an airfield runway detection method is poor in detection effect under existing long linear characteristics. The method comprises that at first, according to a long straight line characteristic of an airfield runway, a Steger algorithm is used for strengthening a linear object in the image, and the central point of the linear object is determined through calculation of a characteristic value of the maximum absolute value of an Hessian matrix; then straight line detection is carried out on the result of the linear objects strengthened by the Steger algorithm through Hough conversion; and finally the position of an airport is determined through straight line connection and statistics. Due to the fact that the Hough conversion detection straight line is carried out on the basis of the result of the Steger algorithm, a great quantity of interference line segments are remove
