Fast Marker Based C-Arm Pose Estimation
To estimate the pose of a C-Arm during interventions therapy we have developed a small sized X-Ray Target including a special set of beads with known locations in 3D space. Since the patient needs to remain in the X-Ray path for all feasible poses of the C-Arm during the intervention, we cannot construct a single marker which is entirely visible in all images. Therefore finding 2D-3D point corr...
متن کاملMarker-less Pose Estimation
The ability to capture human motion precisely has benefits in various applications ranging from biomechanics studies, to physical therapy and exoskeleton control. The current most utilized methods for determining body kinematics and motion rely on either 1) optical systems which require retrofitting a room with an array of expensive cameras and tagging the subject with retro-flective markers at...
متن کاملPredicting Accuracy in Pose Estimation for Marker-based Tracking
Tracking is a necessity for interactive virtual environments. Marker-based tracking solutions involve the placement of fiducials in a rigid configuration on the object(s) to be tracked, called a tracking probe. The realization that tracking performance is linked to probe performance necessitates investigation into the design of tracking probes for proponents of marker-based tracking. A challeng...
متن کاملRelative Pose Estimation of a Spin-Stabilized Spacecraft
This paper presents filtering solutions for estimating the relative trajectory of a spin stabilized satellite. The SPHERES satellites have been selected as the hardware testbed for implementing a Multiplicative Extended Kalman Filter and novel Multiplicative Unscented Kalman Filter. Relative state measurements are provided by imaging fiducial markers on the target. The results from this analysi...
متن کاملVisual Pose Estimation System for Autonomous Rendezvous of Spacecraft
In this work, we consider a tracker spacecraft equipped with a short-range vision system that must visually identify a target and determining its relative angular velocity and relative linear velocity using only visual information from an onboard camera. By means of visual feature detection and tracking across rapid, successive frames, features detected in two-dimensional images are matched and...
