The pose accuracy is mostly affected by the camera hardware, in particular its resolution (the bigger the better) in comparison to its field of view, as well as the marker distance from the camera (the further away the marker, the more imprecision increases). Fractal marker detection and pose estimation. The objective of the test was to demonstrate the capability of the TriDAR system to track an object in space without using targets markers such as retro-reflectors. What do I need to need to modify in order to display diffrent models for different markers at the same time? The following repository is an easy to use package for human pose estimation with UnityBarracuda. From a scan through the aruco docs it seems like if you've calibrated your camera you can estimate the pose (3D location and rotation) of each marker using the estimatePoseSingleMarkers function.
