CNN Photo Horizon Correction Method based on convolutional neural network and residual network structure

摘要

The present invention relates to a method of leveling a tilted image by measuring and using the inclination of the image when the tilted image is inputted. The method includes: a step (a) of generating a learning data set for learning an angle measurement network in accordance with a residual network structure including first and second pulling layers and an angle prediction part; a step (b) of learning an optimal parameter of the angle measurement network; and a step (c) of rotating the image and cropping an empty pixel area.
