A framework for measuring TRE at the tip of an optically tracked pointing stylus
نویسندگان
چکیده
We describe a framework for measuring TRE at the tip of an optically tracked pointing stylus. Our approach relied on a robotic manipulator equipped with a spherical wrist to collect large amounts of tracking data from well defined paths. Fitting the tracking data to planes, circles, and spheres allowed us to derive estimates of FLE and precisely localize target locations. A preliminary analysis of our data suggested that there was bias in the registered pointer tip location that depended on the tilt angle of the coordinate reference frame with respect to the tracking system.

On Fiducial Target Registration Error in the Presence of Anisotropic Noise
We study the effect of anisotropic noise on target registration error (TRE) by using a tracked and calibrated stylus tip as the fiducial registration application. We present a simple, efficient unscented Kalman filter algorithm that is suitable for fiducial registration even with a small number of fiducials. We also derive an equation that predicts TRE under anisotropic noise. The predicted TRE...
متن کاملUltra-Sharpening of Diamond Stylus by 500 eV O+/O2 + Ion Beam Machining without Facet and Ripple Formation
The price of single point diamond tools with a sharp tip is very high due to complex machining process and highly expensive machining equipments. Yet, the performance is not quite satisfactory. In this paper, we have presented a very simple and cost effective machining process for the sharpening and polishing of diamond stylus using low energy reactive ion beam machining (RIBM). In our method, ...
متن کاملStylus Tip Center Position Self-Calibration Based on Invariable Distances in Light-Pen Systems
The light-pen coordinate measuring machine (LPCMM for short) is portable and flexible to measure features including invisible ones in-situ. Since different styluses are needed to measure different features and even during the process of measuring a single workpiece with complicated configurations, to improve the system measurement accuracy it is beneficial to calibrate the stylus tip center pos...
متن کاملHand–eye calibration using a target registration error model
Surgical cameras are prevalent in modern operating theatres and are often used as a surrogate for direct vision. Visualisation techniques (e.g. image fusion) made possible by tracking the camera require accurate hand-eye calibration between the camera and the tracking system. The authors introduce the concept of 'guided hand-eye calibration', where calibration measurements are facilitated by a ...
متن کاملEvaluating haptic feedback in virtual environments using ISO 9241-9
The ISO 9241 Part 9 standard [2] pointing task is used to evaluate passive haptic feedback in target selection in a virtual environment (VE). Participants performed a tapping task using a tracked stylus in a CAVE both with, and without passive haptic feedback provided by a plastic panel co-located with the targets. Pointing throughput (but not speed nor accuracy alone) was significantly higher ...
