White laser, synced scan (3D scanner)

IEEE Computer Graphics and Applications, 1993
A 3-D scanner that employs white laser light and yields high-resolution data in files small enough to be handled on a graphics desktop or readily communicated using a modem is discussed. At its heart is a synchronized sensing system that frees up the axis in the data file.

Exploiting mirrors for laser stripe 3D scanning

Fourth International Conference on 3-D Digital Imaging and Modeling, 2003. 3DIM 2003. Proceedings., 2004
This paper proposes and evaluates the use of a mirror for improving the scanning process when using laser-stripe acquisition devices. We propose to exploit mirrors for two different purposes: automatizing the 3D acquisition process and allowing the scanning of hard-to-reach parts.

Reconstruction of 3D Model Based on Laser Scanning

2008
Three-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, 1998
Generation 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), 2018
Due 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), 2016
Nowadays, 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.
