General approach to error prediction in point registration
A method for the first-order analysis of the point registration problem is presented and validated. The method is a unified approach to the problem that allows for inhomogeneous and anisotropic fiducial localization error (FLE) and arbitrary weighting in the registration algorithm. Cross-covariance matrices are derived both for target registration error (TRE) and for weighted fiducial registrat...
متن کاملRigid point registration circuits
In 1996 Freeborough proposed a method for estimating target registration error (TRE) in the absence of ground truth. In his approach, a circuit of registrations is performed using the same registration method on multiple views of the same object: 1 to 2, 2 to 3, ..., NC –1 to NC , and NC to 1 where NC is at least three and the last registration completes the circuit. Any difference between the ...
متن کاملTarget Registration Error in Point-based Rigid-body Registration: a Worst-case Analysis
The model has to be evaluated in terms of accuracy, robustness and speed. In a first evaluation, sequences of anatomic structures were used. Accuracy and robustness were evaluated by registering reconstructed point clouds with a polygon model from a laser scanner. The first results indicated that the surface model is reconstructed with millimeter precision. An important criterion for the usabil...
متن کاملThe distribution of registration error of a fiducial marker in rigid-body point-based registration
Many image-guidance surgical systems rely on rigid-body, point-based registration of fiducial markers attached to the patient. Marker locations in image space and physical space are used to provide the transformation that maps a point from one space to the other. Target registration error (TRE) is known to depend on the fiducial localization error (FLE), and the fiducial registration error (FRE...
متن کاملDerivation of Expected Registration Error for Point-based Rigid-body Registration
This paper presents two new expressions for estimating registration accuracy in point-based rigid-body registration and points out a danger in using the traditional measure of registration accuracy. Rigid-body registration is appropriate for applications in which relatively rigid parts of the body are involved. In some such applications rigid-body registration is accomplished by aligning two se...
