Reconstruction of 3D Model Based on Laser Scanning
2008Three-dimensional laser scanning can be used to collect spatial location of points rapidly and abundantly, and obtain three-dimensional coordinates of the target surface, which provides new technical means for the rapid creation of three-dimensional image model of the object.

Laser scanning technique for 3D measurement
SPIE Proceedings, 1998Generation of scanning structured light is an initiative triangulation-based method for acquiring range data. Unlike traditional projection of paten diaphragm, diode laser, rotating mirror and CCD camera are employed into our device. Diode laser is modulated to emit a modulated slit laser beam.

Feature detection and scan area selection for 3D laser scanning sensors
2018 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2018Due to the trend towards small lot sizes and fast changes of relevant product features in production processes, the demands for flexible measurement systems with high precision and throughput are constantly growing. By using optical scanning sensor systems, e.g.

Research on laser stripe extraction in underwater 3D laser scanning
2016 IEEE International Conference on Information and Automation (ICIA), 2016Nowadays, 3D laser scanners find a wide range of applications such as object measurement, orthotics and prosthetics, reverse engineering and prototyping, quality control, part inspection and documentation of cultural artifacts. 3D scanning is a fast and accurate method of putting physical measurements of an object onto computer.

Continuous 3D scan-matching with a spinning 2D laser
2009 IEEE International Conference on Robotics and Automation, 2009Scan-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, 2010Three 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, 2018In 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, 2000A 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), 2015The 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 ...
