Abstract

Abstract: 3D scenes can be reconstructed more easily and rapidly with depth camera. However, it is difficult to retrieve items in 3D scenes from a single view depth image, especially for the pose estimation. In this paper, we present a method of pose estimation using convolutional neural network with synthesis depth data, which predicts the items' pose in 3D scenes by regression. This is achieved by (i) synthesizing large amount of depth images with different pose for linear regression using 3D model, (ii) designing a class-dependent linear regression framework, which estimates the object's pose from different classes separately, (iii) reforming LeNet-5 model by representing the loss layer as a linear regression form. The proposed algorithm is demonstrated on different data sets and achieves higher accuracy (average error 4.3°) than other algorithms.
