Visual-lidar Odometry and Mapping: Low-drift, Robust, and Fast
"... Abstract — Here, we present a general framework for com-bining visual odometry and lidar odometry in a fundamental and first principle method. The method shows improvements in performance over the state of the art, particularly in robustness to aggressive motion and temporary lack of visual features ..."

features. The proposed on-line method starts with visual odometry to estimate the ego-motion and to register point clouds from a scanning lidar at a high frequency but low fidelity. Then, scan matching based lidar odometry refines the motion estimation and point cloud registration simultaneously. We show
DETECTION AND ROBUST ESTIMATION OF CYLINDER FEATURES IN POINT CLOUDS
"... ABSTRACT The objective of this work is to develop new methods for efficient automatic 3D modeling of existing industrial installations from point cloud data. Traditionally, cylinder feature extraction algorithms utilize 5D Hough transforms, resulting in impractically high computational complexity. ..."

. A more efficient approach uses a 2D Hough transform to estimate orientation followed by a 3D Hough transform to detect position, but still has extensive runtimes and lacks robustness in dense point cloud data. This work endeavors to (1) further decrease the runtime for cylinder feature extraction
On-Line Dense Visual Odometry with Depth Images using Normals Based Error Functions Supervisor Candidate
"... In this thesis work, we present a method for dense visual odometry which uses depth images registration to compute the transformation between dif-ferent poses. The registration algorithm proposed is able to match 3D point clouds extracted by depth images and can be seen as a variant of the generaliz ..."

of the generalized ICP algorithm based on a plane-to-plane metric. Substantially, we exploit the structure of the point clouds, in particular we take advantage of the information given by the surface normals of each point. A closed form solution is developed for the least-squares estimation prob-lem used to register
Dense RGB-D Visual Odometry using Inverse Depth∗
, 2015
"... Abstract – In this paper we present a dense visual odometry system for RGB-D cameras performing both photometric and geometric error minimisation to estimate the camera motion between frames. Contrary to most works in the literature, we parametrise the geometric error by the inverse depth instead of ..."

REGISTRATION OF 3D POINT CLOUD USING A HIERARCHICAL OBJECT BASED METHOD
"... Point cloud registration is an inevitable problem in many applications, such as modelling in large scale outdoor environment with the point cloud captured by the moving scanner. How to put these point cloud into the same coordinate system fast and efficiently is the bottleneck to accomplish the 3D m ..."

This method makes an extension of SLAM6D in two aspects: 1) The modified surf descriptor is used to find corresponding point pairs to estimate the initial
Robust Reconstruction of Watertight 3D Models from Non-uniformly Sampled Point Clouds Without Normal Information
, 2006
"... We present a new volumetric method for reconstructing watertight triangle meshes from arbitrary, unoriented point clouds. While previous techniques usually reconstruct surfaces as the zero level-set of a signed distance function, our method uses an unsigned distance function and hence does not requi ..."

1Monocular Visual Odometry using a Planar Road Model to Solve Scale Ambiguity
"... Abstract — Precise knowledge of a robots’s ego-motion is a crucial requirement for higher level tasks like autonomous navigation. Bundle adjustment based monocular visual odometry has proven to successfully estimate the motion of a robot for short sequences, but it suffers from an ambiguity in scale ..."
