3D Sketch-based 3D Model Retrieval with Convolutional Neural Network

3D sketch-based 3D model retrieval is to retrieve similar 3D models using users' hand-drawn 3D sketches as input. Compared with traditional 2D sketch-based retrieval, 3D sketch-based 3D model retrieval is a brand new and challenging research topic. In this paper, we employ advanced deep learning method and propose a novel 3D sketch based 3D model retrieval system. Our system has been comprehensively tested on two benchmark datasets and compared with other existing 3D model retrieval algorithms. The experimental results reveal our approach outperforms other competing state-of-the-arts and demonstrate promising potential of our approach on 3D sketch based applications.
