The invention belongs to potential landslide identification fields, it discloses a kind of potential landslide automatic identifying method of the optical remote sensing for taking InSAR deformation into account: obtaining the rate of deformation figure and optical remote sensing image data of target area, and the optical remote sensing image is pre-processed, obtain the optical remote sensing image figure of target area；The terrain information data of target area are calculated；According to the rate of deformation figure of target area, segmentation obtains multiple objects, and chooses terrain classification sample, obtains the characteristic of division element and its threshold value of all kinds of terrain classification samples；The potential landslide areas in target area for being utilized optical remote sensing image acquisition is rejected in classification；Potential landslide object is calculated, potential landslide object is merged with the potential landslide areas in obtained target area, finally obtains target area completely potential landslide areas；Present invention combination optical remote sensing and InSAR rate of deformation information, can quickly and effectively extract potential landslide, the degree of automation and high reliablity, provide technical support for prevention landslide disaster. |
