hVI provides a landslide monitor method with an image type three-dimensional which consists of the sole camera. The proposed method can calculate three-dimensional landslide displacement distance using the immediate image.
The 3D landslide real-time monitor system has an important function for warning debris flows, and a necessary procedure to monitor the hillside stability for a new construction.
