Abstract


With the rapid development of remote sensing technology , remote sensing data processing , get valid information is a hot topic for many scholars . Many research directions in the field of remote sensing is an important technology in the extraction and segmentation of the road , with a good practical military value , the application fields , is an important issue of practical value and research value . Based on the field of remote sensing technology , the advanced experience of learning and summarizes the domestic and international road extraction from remote sensing images , proceed from the common image processing technology , the establishment of a mathematical model for remote sensing road and for improving mathematical model to establish the extraction process . Study the RGB color space , and the pros and cons of the HIS color space , color space model to establish a hybrid filter invalid pixel of remote sensing image , extracted road framework . Compared with traditional methods , the filtering of invalid pixels can be increased by more than 20% . The geometric characteristics of the remote sensing images in the road , a quadrilateral - based regional extension method to achieve road extraction . The VC6.0 development platform , the development of remote sensing image road extraction system at the same time meet the basic color image processing and manipulation . The experiments show that the method is an effective extraction .
