Landslide and form identification method based on YoV4 algorithm

The invention discloses a landslide and form identification method based on a YoV4 algorithm, and the method comprises the steps: 1, obtaining an image containing a landslide region from a satellite remote sensing image, and carrying out the preprocessing of the image, and forming image data containing target identification features; 2, inputting the image data containing the target recognition features into a target recognition model established by using a YoV4 algorithm, and outputting a landslide recognition result image by the target recognition model; 3, determining the shape of the landslide according to the length-width ratio of the landslide recognition result image; 4, acquiring elevation data corresponding to a landslide identification result image area, determining a landslide direction and marking the landslide direction in the image; according to the method, landslide form identification is added, especially landslide direction identification is added, the direction identification accuracy reache
