Embodiment Construction
[0025] The present invention will be further described below in conjunction with drawings and embodiments.
[0026] It is known that the visible light image I taken by the helicopter inspection has a width of Width and a height of Height, according to figure 1 , the classification method is as follows:
[0027] Step 1: Carry out LoG transformation to input image I, to extract the strip shape in the image, obtain strip mask BarMask; LoG transformation, namely known Laplace-Of-Gaussian transformation;
[0028] ,
[0029] Step 2: For the image under the strip mask, use the usual edge detection method to extract the edge, such as the Canny edge detection method; use the Hough transform method for the edge, such as the GradientProgressiveProbabilisticHough transform, to detect the straight line segment; according to the direction of the straight line segment, Quantity and length, to determine whether there are towers in image I.
[0030] The judgment method is as follows:
