Abstract :
A simple and feasible method to retrieve directional fraction of vegetation cover is presented. A digital camera is adopted to capture multi-angle images for a wheat field and trees. The viewing angles are controlled by an automatic multi-angle observation device. After image processing, directional fraction cover and gap probability can be obtained.
