Survey of Rigid Object Pose Estimation Algorithms Based on Deep Learning

Rigid object pose estimation aims to obtain 3D translation and 3D rotation information of the rigid object in the camera coordinate system,which plays an important role in rapidly developing fields such as autonomous driving,robotics and augmented reality.The representative papers on rigid object pose estimation based on deep learning from 2017 to 2021 are summarized and analyzed.The rigid object pose estimation methods are divided into coordinate-based,keypoints-based and template-based me-thods.The rigid object pose estimation task is divided into four sub-tasks:image preprocessing,spatial mapping or feature ma-tching,pose recovery,and pose optimization.The subtask realization of each method and its advantages and problems are introduced in detail.The challenges of rigid object pose estimation are analyzed,and the existing solutions and their advantages and disadvantages are summarized.Based on the rigid object pose estimation method,the articulated object and deformable object pose estimation are analyzed.The common datasets and performance evaluation indexes of rigid object pose estimation are introduced,and the performance of existing methods on common datasets is compared and analyzed.Finally,the future research directions of pose tracking and class rigid object pose estimation are prospected.
