Robust surface registration using N-points approximate congruent sets

Scans acquired by 3D sensors are typically represented in a local coordinate system. When multiple scans, taken from different locations, represent the same scene these must be registered to a common reference frame. We propose a fast and robust registration approach to automatically align two scans by finding two sets of N -points, that are approximately congruent under rigid transformation an...

Fast Registration of Laser Scans with 4-points Congruent Sets – What Works and What Doesn’t

Sampling-based algorithms in the mould of RANSAC have emerged as one of the most successful methods for the fully automated registration of point clouds acquired by terrestrial laser scanning (TLS). Sampling methods in conjunction with 3D keypoint extraction, have shown promising results, e.g. the recent K-4PCS (Theiler et al., 2013). However, they still exhibit certain improbable failures, and...

Markerless Point Cloud Registration with Keypoint-based 4-points Congruent Sets

This paper addresses the registration of LiDAR point clouds. More specifically, we present an automatic method for markerless registration of two such point clouds given in arbitrary local scan coordinates – i.e. without simplifying assumptions such as a common up-vector. Clearly, the critical step of the registration is to find a coarse initial alignment, to be refined with established local m...

Curvature guided surface registration using level sets

We present a new approach for non-rigid surface-registration of 3D objects. By representing the surfaces as the zero-level of a signed distance function in 3D space, our algorithm becomes independent of topology. We propose an extension of Thirion’s Demons algorithm to register the distance images. Our extension includes the use of a curvature term to guide the registration in the direction tan...

Robust Surface Matching for Registration

The ability to accurately register images of patients taken at different times is very important in many medical applications. In most cases, the main reason for registration is to measure changes, and therefore any automatic registration algorithm employed for this task must be able to cope when there are significant differences in the images. In this paper a new algorithm is presented which e...
