Summarizing Image/Surface Registration for 6DOF Robot/Camera Pose Estimation

In recent years, 6 Degrees Of Freedom (DOF) Pose Estimation and 3D Mapping is becoming more important not only in the robotics community for applications such as robot navigation but also in computer vision for the registration of large surfaces such as buildings and statues. In both situations, the robot/camera position and orientation must be estimated in order to be used for further alignment of the 3D map/surface. Although the techniques differ slightly depending on the application, both communities tend to solve similar problems by means of different approaches. This article is a guide for any scientist interested in the field since the surveyed techniques have been compared pointing out their pros and cons and their potential applications.
