The Principle and Application of 3 D Sensors

2016

Gradual development of modern trends with more emphasis on visualization and measurement accuracy have resulted in the continuous improvement of measuring instruments, which are very closely linked to Personal Computers and/or Programmable Logic Controllers to the displaying unit and leads to greater utilization of 3D technology. 3D technology is used in security, biometrics, and in many other fields. This contribution is focused on understanding the issues of scanning and its advantages and disadvantages. It serves as a complete overview of the structure of the 3D sensors and their use.

3D Laser Scanners: History, Applications, and Future

A 3D scanner is a device that analyzes a real-world object or environment to collect data on its shape and possibly its appearance (i.e. color). The collected data can then be used to construct digital three-dimensional models. 3D laser scanning developed during the last half of the 20th century in an attempt to accurately recreate the surfaces of various objects and places. The technology is especially helpful in fields of research and design. The first 3D scanning technology was created in the 1960s. The early scanners used lights, cameras and projectors to perform this task. Due to limitations of the equipment it often took a lot of time and effort to scan objects accurately. After 1985 they were replaced with scanners that could use white light, lasers and shadowing to capture a given surface. Many different technologies can be used to build these 3D scanning devices; each technology comes with its own limitations, advantages, and costs. Many limitations in the kind of objects t...

3-D Imaging Techniques and Review of Products

3-D imaging has applications in several fields, such as design, entertainment, manufacturing, defense, security, construction, medical, medicine and for visual aid. Even though 3-D imaging is known since long time, the advancement of 3-D technology was gradual because of the slow advancements in 3D visualization, quality of 3-D sensors, less availability of processing power etc. Recent years, we have computers with more power with multi-cores, high precision 3D image sensors and 3D displays. This has led to the adoption of 3D imaging across various verticals. This paper discusses the techniques used to obtain the 3-D image, the essential features required for 3-D camera and reviews some of the 3-D cameras in the academic and market sectors.
