| titleOfInvention | A Light Adaptive Green Field Extraction Method |
| abstract | The invention discloses a light adaptive green field extraction method. The method first uses the perfect reflection white balance and brightness uniformity processing to obtain grayscale and color images with uniform brightness, which improves the algorithm's adaptive degree to light; Separating the h channel for Gaussian filtering makes the color of the color image more uniform and improves the integrity of the green field extraction; then, the green channel is separated by the design formula, and the Otsu method is used for binarization to obtain the green part of the picture. ; Finally, through erosion expansion, small area deletion, and convex envelope calculation methods, a complete green site outline is finally obtained. Based on the method provided by the present invention, there is a complete green field extraction effect for photos with different brightness, photos with different brightness in different regions, and photos with deviation of green color in extreme cases. |
