Disclosed herein are an apparatus and method for generating a skeleton model using deep learning. The method for generating a 3D full-body skeleton model using deep learning, performed by the apparatus for generating the 3D full-body skeleton model using deep learning, includes generating training data using deep learning by receiving a 2D X-ray image for training, analyzing the 2D X-ray image of a user using the training data, and generating a 3D full-body skeleton model by registering 3D local part bone models generated from the result of analyzing the 2D X-ray image of the user.
