Embodiment Construction
[0067] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0068] See details figure 1 , figure 2 , image 3 and Figure 4 , the technical scheme that the present invention adopts is: a kind of airport area extraction method based on saliency and LSD line detection, comprises the following steps:
[0069] Step 1, establish the original airport detection data set D;
[0070] Step 2, extract the remote sensing image A one by one from the data set, and perform down-sampling, the specific implementation method is as follows:
[0071] Step 2.1, first read the original remote sensing image, and obtain the width, length and channel number of the image;
[0072] Step 2.2, then use the input and output functions of GDAL to input the length, width and number of channels of the image, and set the downsampling size to 4000*4000;
[0073] Step 2.3, save the image after downsampling, the for...
