| titleOfInvention | Color steel tile factory building extraction method based on remote sensing image |
| abstract | The invention discloses a remote sensing image-based color steel tile factory building extraction method which comprises the steps of obtaining a remote sensing image, preprocessing the remote sensing image to obtain a spectral reflectivity image, wherein the remote sensing image at least comprises blue, green, red and near infrared wave bands. Respectively carrying out wave band operation R on the remote sensing images B ×(R B ‑R R ) And 1-mean (R) B +R G +R NIR ) (ii) a Then combining the two parts; or respectively carrying out wave band operation (R) on the remote sensing images B ×(R B ‑R G )×|R G ‑R R |) 1/3 And mean (R) NIR +R R )‑mean(R B +R G +R R ) (ii) a Then combining the two parts; two kinds of extraction formulas for the color steel tile can be obtained. The invention also discloses a corresponding extraction system. Because the spectral reflectivity of the ground objects in blue, green, red and near infrared bands has difference, the core idea of the invention is to enhance the difference through band operation and extract the target ground object through the optimal threshold value, and the target ground object of the invention is the color steel tile so as to realize the extraction of the color steel tile factory building. |
