Abstract:
We are using a drone to obtain aerial views of grape farms to check the growth of grapevines. The shadows cast by the branches (cordons) in captured images differ depending on the location of the drone when the images were captured. The problem with stitching images of cordons with shadows together is that the cordons often appear disjointed at the edges of individual images. To solve this problem, we propose a method for removing elements other than cordons in the images captured from above, so that cordons only can be extracted from the images. We tested the effectiveness of this method using images in which the cordons were disjointed at the edges of the images after stitching by conventional methods.
