Abstract
There are still problems with high algorithm complexity due to the high precision of the tracking method for special markers, a position and pose estimation method based on rigid body motion analysis is proposed in this paper. This method used a rigid body structure to register and track virtual scenery and observation viewpoints. According to the spatial beam convergence idea, it can accurately track the movement of a rigid body structure, making the pose estimation process more flexible and results more accurate. This method uses a large amount of spatial analytical geometric theory knowledge to make it reliable in theory. The experiment also verified the method’s anti-jamming, positioning accuracy, modularity, etc. The experimental results show that the use of rigid body structure to simulate the three-dimensional virtual observation point of view can accurately control the first-person viewing angle change, and the user experience during the roaming process is obvious higher than traditional visual interaction.
