چکیده

We introduce a data processing pipeline designed to generate registration markers from range scan data. This approach uses curvature maps and histogram-templates to identify local surface features. The noise associated with real-world scans is addressed using a (common) Gauss filter and expansion-segmentation. Experimental results are presented for data from The Digital Michelangelo Project.

Range Scan Registration Using Reduced Deformable Models

We present an unsupervised method for registering range scans of deforming, articulated shapes. The key idea is to model the motion of the underlying object using a reduced deformable model. We use a linear skinning model for its simplicity and represent the weight functions on a regular grid localized to the surface geometry. This decouples the deformation model from the surface representation...

Registration Using Cortical Surface for Microscope-based Image-guided Neurosurgery

Microscope-based Image-guided Neurosurgery seeks to establish an accurate correlation between preoperative images and the current surgical scene under the microscope through rigid registration. Information, drawn from diagnostic image data, including computerized tomography (CT) and magnetic resonance images (MRIs), can be projected into the operating microscope, overlaying the surgical field i...

Scan registration for autonomous mining vehicles using 3D-NDT

Scan registration is an essential subtask when building maps based on range finder data from mobile robots. The problem is to deduce how the robot has moved between consecutive scans, based on the shape of overlapping portions of the scans. This paper presents a new algorithm for registration of 3D data. The algorithm is a generalization and improvement of the normal distributions transform NDT...

Incorporation of a laser range scanner into image-guided liver surgery: surface acquisition, registration, and tracking.

As image guided surgical procedures become increasingly diverse, there will be more scenarios where point-based fiducials cannot be accurately localized for registration and rigid body assumptions no longer hold. As a result, procedures will rely more frequently on anatomical surfaces for the basis of image alignment and will require intraoperative geometric data to measure and compensate for t...

Registration methods for gross motion correction during image - guided kidney surgery

Purpose The National Cancer Institute reported an increased incidence of kidney cancer over the past 30 years, projecting over 54,000 new cases in 2008 [1]. Surgical intervention is the established method of treatment, with partial nephrectomies preferred when physiologically practical [2, 3]. Along with nephron-sparing approaches, minimally invasive methods have gained ground due to reduced bl...
