The accurate estimation of three-dimensional (3D) object pose is important in a wide range of applications, such as robotics and augmented reality. The key to estimate object poses is matching feature points in the captured image with predefined ones of the 3D model of the object. Existing learning-based pose estimation systems utilize a voting strategy to estimate the feature points in a vector space for improving the accuracy of the estimated pose. However, the loss function of such approaches only takes account of the direction of the vector, resulting in an error-prone localization of feature points. Therefore, this paper considers a projection loss function dealing with the error of the vector field and incorporates a refinement network to revise the predicted pose to obtain a good final output. Experimental results show that the proposed methods outperform the state-of-the-art methods in ADD(-S) metric on the LINEMOD and Occlusion LINEMOD datasets. Moreover, the proposed method can be applied to real-world practical scenarios in real time to simultaneously estimate the poses of multiple objects.
