In this paper, we compare three different marker based approaches for six degrees of freedom (6DOF) pose estimation, which can be used for position and attitude control of micro aerial vehicles (MAV). All methods are able to achieve real time pose estimation onboard without assistance of any external metric sensor. Since these methods can be used in various working environments, we compare their performance by carrying out experiments across two different platforms: an AscTec Hummingbird and a Pixhawk quadrocopter. We evaluate each method's accuracy by using an external tracking system and compare the methods with respect to their operating ranges and processing time. We finally compare each method's performance during autonomous takeoff, hovering and landing of a quadrocopter.
