Continuous 3D scan-matching with a spinning 2D laser

2009 IEEE International Conference on Robotics and Automation, 2009
Scan-matching is a technique that can be used for building accurate maps and estimating vehicle motion by comparing a sequence of point cloud measurements of the environment taken from a moving sensor. One challenge that arises in mapping applications where the sensor motion is fast relative to the measurement time is that scans become locally ...

Non-rigid registration and rectification of 3D laser scans

2010 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2010
Three dimensional point clouds acquired by range scanners often do not represent the environment precisely due to noise and errors in the acquisition process. These latter systematical errors manifest as deformations of different kinds in the 3D range image.

Optical scanning of laser line sensors for 3D imaging

Applied Optics, 2018
In scanning laser triangulation sensors for 3D imaging, the achievable throughput is strongly limited by the moving mass. By realizing an optical scanning approach rather than repositioning the entire sensor, this limitation could be reduced, leading to a reduced measurement time.

Helmet accommodation analysis using 3D laser scanning

Applied Ergonomics, 2000
A method used to determine the probable population accommodation of a helmet sizing system is described. The method involves the use of 3D laser scanning, as a means of measuring helmet standoff distance (distance between the inside of the helmet and the skull), and the selection of a representative sample of test subjects.

Evaluation of registration methods for sparse 3D laser scans

2015 European Conference on Mobile Robots (ECMR), 2015
The registration of 3D laser scans is an important task in mapping applications. For the task of mapping with autonomous micro aerial vehicles (MAVs), we have developed a light-weight 3D laser scanner. Since the laser scanner is rotated quickly for fast omnidirectional obstacle perception, the acquired point clouds are particularly sparse and ...

3D Laser scanning system and 3D segmentation of urban scenes

2010 IEEE International Conference on Automation, Quality and Testing, Robotics (AQTR), 2010
This paper dwells upon the promising 3D technology for mobile robots and automation industry. The first part of the paper describes the design details of our own 3D Time of Flight (TOF) scanning system based on 2D laser range finder. The second part presents a specific segmentation technique for 3D outdoor urban environments by the common detection of ...

3D Laser Scanning for Image Guided Stereotactic Neurosurgery

1995
While this work is in its very early stages, the 3D laser scanner shows significant promise as a surgical localization device with advantages over other sensing methods. Accurate 3D surface extraction and matching, a central problem in computer vision, is the key to frameless stereotaxic neurosurgery using this technique.

Application of 3D laser scanning in building surveys

Journal of Building Survey, Appraisal & Valuation, 2012
Laser scanning of a building facade can generate a highly detailed, three-dimensional model of a facility. Multiple collections of data, or multiple scans over a number of years using a point cloud to model points on the structure and map deviation of those points from a selected baseline, can illustrate specific locations for focus of repairs due to ...

3D Laser Scanning for Heritage: Advice and Guidance on the Use of Laser Scanning in Archaeology and Architecture

2018
The first edition of 3D Laser Scanning for Heritage was published in 2007 and originated from the Heritage3D project that in 2006 considered the development of professional guidance for laser scanning in archaeology and architecture. Publication of the second edition in 2011 continued the aims of the original document in providing updated guidance on ...
