The invention relates to the technical field of geological disaster monitoring, in particular to a landslide analysis method based on deep learning and satellite images. The method comprises the following steps: S1, acquiring a satellite remote sensing image and landform data of a landslide area, and preprocessing the satellite image; S2, constructing a feature set according to a satellite image preprocessing result in combination with the landform data; s3, constructing a training sample set based on the feature set, classifying and positioning the areas conforming to the initial features of the landslide, and outputting the boundary and the distribution range of the landslide; s4, outputting an expression result according to the landslide boundary and the distribution range, and performing multi-index precision evaluation; and if the precision is smaller than the set value, returning to the step 2 and / or the step 3 to carry out adjustment and optimization. The invention aims to provide a landslide analysis method based on deep learning and satellite images so as to realize rapid and high-precision landslide analysis through the satellite images.

The utility model discloses a rotating disc type positioning ink-jet printer which comprises a base body, a rotating disc and a rotation driving mechanism for driving the rotating disc to rotate are rotatably installed on the base body, positioning notches are distributed in the circumferential edge of the rotating disc, and the outer sides of the positioning notches are in an open state and used for hanging goblets upside down so that the bottoms of the goblets can face the right upper portion. The base body is further provided with a code spraying assembly and a locking mechanism, the code spraying assembly is located above one of the positioning notches of the rotating disc and used for spraying ink to the bottom of the goblet, and the locking mechanism is used for fixedly locking the goblet staying below the code spraying assembly in the corresponding positioning notch. The rotating driving mechanism can enable the goblets hung upside down on the positioning notch to sequentially stay below the code spraying assembly one by one. The goblet bottom ink jet device has the advantages that the goblet bottom ink jet can be completed in batches, the goblets with ink jet can be recognized and positioned more easily in the follow-up silk-screen printing process, and therefore the success rate of silk-screen printing marks and patterns of the goblets can be improved.
